12 Must Know Things You Need To Know When Buying Hardwood Flooring!


I am about to reveal to you some key facts that hardwood flooring manufacturers do not tell you about and it could save you thousands of dollars on your next hardwood floor.

Being an owner of a third generation family flooring business, I have seen flooring stores come and go all the time. I have seen gimmicks and tricks from manufacturers, representing their flooring products with impressive statistics and new "technologies" to guide people into how "their" product is better than the next. Sometimes the changes in product are actually viable and do work, but others are just plain nonsense.

Let's talk about some things you may not know when it comes to hardwood flooring, both engineered and solid hardwood.

Did you know that wood flooring has a comfort level too? Wood flooring will perform best when the indoor environment in which it is to be installed has a relative humidity range of 35 to 55 percent and a temperature range from 60 to 80 degrees Fahrenheit. This is about the same comfort range that we as humans enjoy.

Let's talk about the first thing you must do as an installer and the home owner. Ready for this...READ THE INSTRUCTIONS FIRST! Before you go gung ho and rip open the boxes, as most men do, take 10 minutes and read the complete instructions for the material provided. There should be a copy that comes in every box of material. Sit back, have a beer, and READ!

Now that we have that clearly understood, you need to INSPECT to know what to EXPECT!

1. Acclimation: The moisture content of the wood and subfloor must be within 2-4 percentage points of each other and the subfloor must not exceed 12% moisture content. The farther the percentage points are away from the subfloor moisture percentage, the more problems you will have. For proper acclimation, material must achieve room temperature (65-80 degrees F) for 24 hours PRIOR to installation. This means that the heat has to be on and working way before you try to install the flooring. To get proper acclimation, store the material according to the manufacturer's directions. The instructions will specify whether to store opened or unopened and whether to store in the center of the room or at the edges. This leads into the next big topic of moisture content.

2. Moisture Content: What is the ideal moisture content of the actual hardwood product? Every manufacturer will very slightly, but the average approved moisture content in the hard wood flooring itself should be between 6-9%. For example, if the moisture content of the subfloor is 12% and the hardwood flooring is 9% there is a 3% difference between the two wood products, which is in the allowable tolerance of installation. Although some movement can be expected even in this range, dramatic expansion and contraction can happen outside of these measurements. There are several electronic moisture meters available on the market to test the moisture content of the hardwood and subfloor. These are generally a pin probe type meter and they can give you an immediate reading of your wood's moisture level. It is very important that it is set to the species of wood that you are installing and that you take moisture measurements from several boxes of material and from several areas of the subfloor throughout the area that is to be installed.

3. Climate Control: Climate control might be the single most common reason for customer dissatisfaction with their hardwood purchase. It is CRITICAL, that the proper temperature and humidity level be maintained throughout the life of the hardwood installation. Improper climate control will result in the material swelling in the summer and shrinking, or gapping, in the winter. Without proper climate control within the house, gapping and shrinking will definitely occur. In the Northwest we do not have a huge problem with this issue unless there is a device used in the home which dries out the air to an extreme amount like a wood stove. This is why a pot of water is ALWAYS recommended to be kept on the wood stove when using it as a heat source. The pot of water keeps moisture in the air. Special Note: Some products that are constructed with HDF cores, are more stable and less prone to expanding and contracting.

4. Floating Floors: A key thing people miss when installing floating floors is to allow for an expansion gap around the room. Just as real dimensional lumber expands and contracts, so does your floor. There must be enough space left at vertical surfaces, like walls and posts to allow for this movement. The larger the area the more space that is required. Rule #1 - Always leave the required expansion gap called for by the manufacturer. Rule #2 - If your installer says that it is not necessary, fire them and refer to rule number one.

You can cover all expansion gaps with wood wall base or quarter round wood trim or a combination of the two.

5. Expansion Joint: Expansion joints are almost always required between rooms, where a room meets a hall or in large expanses. You can use a "T" molding in these areas to allow for the floor expansion and contraction.

6. Moisture Control: Here is a big one! Moisture in the subfloor, called "hydrostatic pressure or vapor emissions", is a MAJOR reason for flooring failures. The subfloor is not to exceed 65% relative humidity. There are several moisture meters that can be used on the floor that provide accurate readings, or a calcium chloride test, used for "concrete floors". If your wood subfloor is above 12% with a meter, do not lay the floor. If your wood subfloor is above 12% then you have to find out why - it could be a new floor and just needs to dry out. If you have concrete floors, you have to find out the source of the moisture. If you still cannot figure out why the floor is above 12%, don't use hardwood. Period. I mean it...you will kick yourself. If your floor is OK to install, remember to always float an engineered floor over 8 mil plastic when going over concrete so as to eliminate and minimize water vapor coming through the concrete floor.

7. Glue down Flooring: In residential installations, most flooring that is engineered is either click together or tongue and grove. I don't think I, personally, would ever glue down an engineered floor. It is an acceptable way to install but I find that it is terrible to rip out years later. Either glue it together or click it together but don't glue it down to the subfloor unless you have a very specific reason to. I have seen more problems even stapling it down to the subfloor. Stapling down your engineered floor will just lead to squeaks and creeks that will drive you nuts. Pull out the instructions that you threw in the garbage and look up the manufacture's installation methods, then go file the instructions with your purchase receipt for future reference.

8. Nail Down Flooring: A very common mistake we have seen in solid flooring installations is proper nail length, gauge of the nail, and spacing between nails. Always refer to the manufacture and double check the subfloor thickness. When using a pneumatic nailer, pay close attention to proper PSI settings.

9. Natural Product Variations: One of the inherent beauties of hardwood is the differences between boards and how much or little they accept stain. No two pieces will ever be alike and that is one thing that makes wood flooring so luxurious and realistic compared to laminate flooring. Pay careful attention to the layout and selecting the color and grain of each board when you are working with the product. Work out of 4-5 boxes at a time when doing a layout, this will randomize any variations between boxes of hardwood.

10. Culled Material: In every natural product like wood, there will be some pieces that, while not defective, and within industry standards, are not what the consumer, you, wants visually. Generally allow for 5-10% waste factor on material. This means that you need to buy 5-10% more material then what your job physically measures out to be. Larger jobs of 1000+ sf could work with 5% while jobs under that square footage can figure 10%.

When buying material from the "Big Box" stores you have to keep in mind that when they purchase materials for a "stocking special" they purchase a product that they can sell at the lowest possible price to use in their ads. This means that the hardwood that they pick up is "Tavern Grade" which means it does not meet the specs of normal running line material. The product will have more voids, mis-filled holes in the face of the hardwood, warped boards both side to side and up and down, and broken toungs. This product will have a lot more waste factor to it, even as much as 20-25% compared to the professional flooring stores stocking inventory. Buyer beware, what you could think is saving you that 10% difference in price, could be costing you 20-25% more in having to buy more wood for the same size job. Oh, and by the way, always keep 1-3 full boxes of material for doing repairs. Do not return them to the store. You will NEVER be able to match the floor again should you need to. Paint would fall into this same realm of thinking. When you need to touch up a wall, they will NEVER be able to exactly match the color. In hardwood there is not only color to match but grain of the wood, board width, color and the number one factor, gloss level of the hardwood or "luster".

11. Scratches: All hardwoods scratch - it's a fact of life. You just cannot change it. You will scratch, scuff, and dent your hardwood under the right conditions. Scratches occur more frequently under chair legs that are small in diameter and at entry areas where abrasion dirt is tracked in on the bottom of shoes. The industry has developed more scratch resistant surfaces like those containing aluminum oxide, they tend to show less scratching but the wood still dents under pressure. To help save your floors use felt chair protectors under all of your free standing chairs. Area rugs are great for rolling chairs in the kitchen, or replace the cheap plastic wheels with rubber barrel casters. The more expensive casters will spread the weight of the chair out more efficiently. The best first line of defense is an area rug by the front door or a tiled entry way to catch the dirt and sand "before" it gets dragged across the hardwood floors. Good rules of thumb, shoes get checked at the door.

12. Cleaning: For heaven sakes ask a flooring professional! Your wood floors are tough but they are delicate when it comes to moisture and cleaners. Throughout this article we have talked about moisture, now we don't want to ruin the floor by trying to maintain it improperly. Follow the manufacturer's instructions.

DO NOT: Use a wet mop system, a steamer, a bucket and mop, any "Wax" finish, no soaps, no polishes, and for heaven's sakes do not over wet your floor with a wet mop.

The best way to clean your floor is to use a microfiber mop and spray a professional hardwood cleaner onto the mop head, to dampen the head, and then clean your floor. If you see streaking or a wet trail, you have used too much cleaner and immediately wipe up the excess with a terry cloth towel.

If you treat your hardwood floors with the love you would treat your wood dining room table, you will be happy for years to come.

How to Fit Solid Wooden Flooring


Making sure that your wooden floor is finished and laid correctly, will save you lots of money in the long run.

These 10 key factors must be taken into account when fitting a solid wood floor.

1.Height allowance

2.Sub floor Types

3.Installation methods

4.Skirting

5.Quantity to order

6.Quality and Moisture content of wood on arrival

7.Acclimatization of the wood on site

8.Expansion gaps

9.Direction of boards

10.Maintenance

1. Height allowance: First thing to check is whether the thickness of the new floor you have chosen and the possible addition of a sub base will affect your room in any way. Either by head height on low beams, ceilings or doorways or will it create a step into leading rooms.

2. Subfloor: What is the existing subfloor? In all cases check the moisture level of the sub base. Fit a solid wood floor anywhere near moisture and you are wasting your time and money. Generally all ground floor bases are prone to moisture problems at some time or other, so adequate moisture proofing is essential. First floors are less prone and less precaution is needed. Different sub bases include, concrete, wooden beams, chipboard planks and old floor boards.

3. Installation methods: There are four different methods of installation each one has its own advantages and disadvantages and specific applications. Gluing: used on both concrete and chipboard sub bases where there is an even and clean surface. Can be messy and glue is expensive. Nailing: used on wooden beams, chipboard and old wooden floor sub bases. Excellent long lasting and strong method but a special nailer is required. Floating: the new floor is not attached to the sub base by gluing or nailing but is floated on top of it. For this method you will need to use an underlay that you wooden floor rests upon. Underlays are good in that they provide a moisture and acoustic barrier Sticky membrane: This is similar to floating a floor but the underlay used is sticky on one side. But be warned if you are not experienced in this method of installation it is very difficult, as the sticky side is extremely sticky and of you get the board in the wrong place you will have extreme difficulty in adjusting it.

4. Skirting: is decorative and provides a necessary cover for the expansion gap that you need to leave around your solid wood floor. You can undercut the skirting, remove the skirting and refit it later or fit beading up to the skirting which will cover the expansion gap.

5. Quantity to order: To calculate the quantity of timber to order measure the rooms and calculate the square meters, then you must add a minimum of 5% extra on top of your area to allow for cutting and wastage. It seems like an unnecessary expense, but it is unavoidable. If you have lots of corners and small rooms it is advisable to allow 10%. The last thing you want is to run out and then not be able to get matching timber.

6. Quality and Moisture content of wood on arrival: Due to the popularity of wooden flooring, it has become a very big industry. The benefit of that to you the consumer is that it has become very competitive. So good quality wood is available at cheaper prices, however Do Not necessarily go for the cheapest you can find, for the following reasons. Floors boards have gone through multiple stages of manufacture from being cut down and machined to be kiln dried and finished. All these stages cost money and if the manufacturer has skimped on these to keep his costs down ultimately the quality of the final product will be inferior. Cheap boards that do not fit together or warp are not cheap in the long run. The moisture content of the wood on arrival at you premises should be between 8% and 12%. It is unlikely that you will have a moisture reader, so will be difficult for you to measure this. This is an advantage of using a professional. They can ensure that these factors are correct and it is their responsibility to do so. Make sure they do.

7. Expansion Gaps: This is the big one. In my experience people generally tend to underestimate the expansion and contraction properties of wood. When a floor is on the move and there is no space for it to go into, nothing can stop it. It will buckle itself and it will break walls if necessary for it to expand. Therefore it is vital to leave a gap all around your floor into which the floor can expand, about 15mm is preferable. Please ensure that this gap is consistent all around including doorways.

8. Acclimatization of the wood on site: This is a long debated subject amongst floor fitters and my beliefs are based around natural laws. Acclimatizing wood in a very dry centrally heated room during winter is going to give you problems as it expands in the summer months and conversely putting wood on site in summer months with all the windows and doors open is going to give you big gaps in the winter months as the wood contracts. Likewise there is no point in acclimatizing wood at any time of year on a building site as this is not the environment that the wood will always live in.

So what does one do - Well these are the ideals: wood arrives from the factory at between 8% and 12% and the ideal humidity of a room for wooden floors is between 40% and 60%. Keep within these ranges when you fit your floor and keep the room at this humidity and you will never ever have a problem with you floor. Hiring a professional takes this worry away from you, but ensures that your professional gives you a guarantee on his workmanship. In doing so he is stating he is comfortable with his level of skill and knowledge.

Fitting engineered floors certainly does negate a lot of these problems as they do not expand or contract to nearly the same degree as a solid wood floor.

9. Direction of boards: There is no right or wrong here. And it is generally a matter of taste, but there are a few guidelines. If you are fitting onto existing rafters or batons you do not have a choice as the boards have to run at 90 degrees to the rafters. General rule of thumb is to run the boards away from the door leading into the room. Looking down the length of the board tends to make the room look larger. Boards running cross ways tend to be jarring to the eyes. Likewise run boards along the longer length of the room, for instance a long hallway with the boards running across the short length looks strange. If in doubt and if you are a little bolder try going diagonal it has a great affect.

10. Maintenance: Methods used will vary according to the type of finish you have. Suffice to say that a little ongoing maintenance will save you a lot of effort and money down the line. Wooden floors are very practical and very easy to keep clean and looking great, but do not just ignore them once you have fitted them. Follow the advice from your layer or wood supplier.

Don't Let This Happen to Your New Hardwood Floor (Avoiding Flooring Failures)


I am called to inspect probably twenty to thirty solid hardwood floors every year that after several weeks or months have started gapping. A quick reminder: solid hardwood floor planks are each one piece of wood, whereas engineered wood planks are several different layers of wood glued together-very much like plywood. Once-in-a-while I'll see an engineered wood with gapping. In either case, it is a serious and very expensive problem. If you will take the time to read the rest of this article, you can be sure this won't happen to you, I promise.

"Moisture levels" are very important with solid hardwood flooring. All wood has moisture of some amount. When a solid wood floor has been installed, especially if nailed/stapled in, and then starts gapping at the seams so that there is space between adjacent boards, it is because they have shrunk. The only other possibility is that your house has expanded, but I'm pretty confident that has never happened and never will. So, why did the boards shrink? Because they lost moisture since being installed. When wood dries out, it shrinks, when it gets wetter, it expands. Okay, now we're getting to the very important part.

Most people are familiar with the term "acclimation". Most people know that wood flooring, even laminates (like Pergo) is to be acclimated before being installed. Usually the instructions say to acclimate for 48 hours, or 3 days, or whatever, then install. THAT IS NOT CORRECT. If you acclimate the product as outlined by the manufacturer for the proper time, then install it, and then it gaps, it will not be warrantied or replaced by the manufacturer. The small print on flooring installation is this: when the installer installs the flooring, he/she accepts that the flooring and subfloor are suitable for installation. The problem is, sometimes the wood flooring is showing up at the house to be acclimated at 15% moisture level, and is to be installed in a home with the subfloor having 6% to 9% moisture level. There is no way that flooring can acclimate to those conditions in a few days. It will still be too wet. And after it is installed, it will shrink-causing gapping. And the worst part, the flooring will have to be pulled up and thrown away. It is not a correctable situation.

I need to interject one small point here. "Some" gapping on solid hardwood flooring is very normal, especially if you live in an area with real seasonal changes like I do eastern Washington. Our homes here will invariably be drier in the winter and wetter in the summer, causing some minor gapping and is perfectly normal. One sure way to know if the gapping is normal is if it pretty much disappears each year during the wetter time. But the gapping I'm talking about is not like this. One lady showed me how some spaghetti that had fallen on the floor had rolled into the gaps. Or if your missing one or more of your favorite pets-that is also a clue.

THE SOLUTION So before this horrible scenario happens, make sure the following is done before your new floor is installed. The flooring needs to be moisture checked with a wood meter. There are pin meters (invasive) and magnetic (non-invasive), either of which will work. However, these run $200 to $300 or more. Insist that the installer have the moisture checked, especially as it will be the installers BIG problem if later you have gapping. Because you know what will happen? The manufacturer will send me to look at the floor, I'll make a lot of measurements of dimensions and moisture levels, and using the Wood Handbook's coefficient of dimensional change tables, I'll be able to determine what the actual moisture level of the wood was at the time of installation. I'll find that it was too high (or WAY too high), and the finding will be that the wood floor was not acclimated to the home's normal environment before being installed. OUCH! That will cost somebody a lot of money, and will cost you at least a lot of hassle with the issue of replacement, etc. You don't want that, and neither do I.

By the way, engineered wood should definitely be acclimated as well, although some of the manufacturers do not want the cartons opened for acclimation and some do, so pay attention to that. Also, laminates (which are real layers of wood similar to engineered except for the top layer which is melamine (aluminum oxide or similar) are also to be acclimated but I've never seen a claim rejected because the floor wasn't acclimated. Typically laminates and a lot of the engineered woods are "floating" which means they connect together and become one unit. Any dimensional change does not normally cause gapping but rather a change of the amount of clearance (perimeter expansion space) at the walls. Some of these issues I'll cover in another article.

TO SUMMARIZE: With any kind of wood flooring, but especially with solid hardwood, be sure that the moisture levels of the wood is within 2% to 4% of the subfloor the flooring is going on top of. In my part of the country where the relative humidity of homes is usually between 25% and 40%, the flooring should be between 6% and 9% before being installed. That leads to one of my favorite phrases, "IMAGINE NO GAPPING!".

10 Questions to Ask Your Hardwood Flooring Supplier


10 Questions to Ask Your Hardwood Flooring Supplier Before Purchasing

1. If there are any problems, who do I call?

Most flooring stores will be buying the flooring they are selling to you from a distributor who purchases the flooring from the manufacturer. Sometime, especially with products coming from overseas there is more than one distributor involved. In many cases if you have an issue with your flooring and complain to the retailer they will call the distributor and let them know there is a complaint, the distributor will tell the manufacturer there has been a complaint. In most cases the manufacturer will deny the complaint and if you are lucky they will even send a representative to deny your claim in person. Most retailers would correct a manufacturing problem to make their customers happy because they are the ones dealing with the customers face to face but in reality they do not have the final say unless they want to replace the flooring out of their own pocket. The manufacturer is so far removed from the actual client that they know it is better for their bottom line to deny the claims and assume they will never have to deal with the issue because they are so protected by their warranties. Picture a person at a desk with a pile of hardwood flooring claims on their desk with a big stamp that says "denied".

2. How durable is the finish?

Durability is probably the most important things to consider when purchasing a prefinished hardwood floor. The finish is what you are actually walking on and must be very durable to have a beautiful lasting floor for years to come. Many imported prefinished floors have very little durability and the finish can be taken off with a few swipes of 150 grit sandpaper. When buying hardwood there are a few ways to test the finish: one would be to take 150 grit sandpaper and rub the finish to see if the finish will come off and two would be to firmly press the edge of a coin against the finish, a quality finish will dent but not come off. Quality manufacturers will have aluminum oxide or better yet titanium oxide hardeners in the finish. Many offshore manufactured products will say they have aluminum oxide in them but actually do not. To test if a hardwood floor has aluminum oxide in the finish simply put the sample in your microwave and if it sparks, it does indeed have aluminum oxide in the finish. I know that may seem a little strange but it's something worth checking because hardwood flooring is a big investment and you want to know the durability of the finish.

3. What is the structural and surface warranty?

This is a very important part of choosing a hardwood floor. Anyone can put a 25, 30, or 40 year warranty on the finish of their product but the real question is; will they stand behind their warranty. Many large hardwood flooring manufacturers have warranties that are up to ten pages. When you read through the entire warranty and all of the exclusions it really gives the client the impression that there is actually no warranty at all. The problem is most consumers don't take the time to read the warranty and are shocked when they find out the issue they are having with the flooring is one of the "exclusions". Most warranties will say that there is an industry standard of 5% margin for error which means that when your entire floor is complete the manufacturer is allowed to have 5% of the boards defective. That means a finished floor of 1000 square feet would be allowed roughly 100 boards with any kind of defect.

4. What is the waste factor of the flooring?

The waste factor of the flooring is an important issue as well. If 10-15% waste is what is suggested by the manufacturer than that means you will have to buy that much more to get enough to install your entire floor. The higher the recommended waste factor the lower quality the product. You may find when comparing products for price on may be more than the other but you must factor in the difference in waste to the price. A floor for $6 with 3% waste would cost you $6.18 which would be the same cost as a floor with 10% waste that is $5.62 and the product with 3% waste would definitely be a higher quality product. The bottom line is you shouldn't have to sort the waste out of the boxes; the manufacturers should be taking the waste out at the plant so you are only getting good quality pieces you can install in your floor.

5. What is the average length of the flooring boards?

The question of the average board lengths is one that is not commonly asked when it comes to hardwood flooring. It is something not a lot of people think about until it is brought up. The longer the average length of the floor the better the floor looks especially in large rooms. One foot and two foot lengths produce a very choppy and unattractive floor. The box size is not the only way to tell what the average length is; you can have an 8' box with all short pieces in it. Many offshore manufactured products are in four foot boxes with will definitely ensure you are getting a floor with very short lengths. It is not only offshore products that have short lengths but many North American made products as well. One very high end Canadian manufacturer has an average length of 27-29" in their 3-1/4" Select and Better Red Oak.

6. What is the moisture content of the flooring?

Moisture content is a very important factor when installing hardwood flooring. You need the flooring to be at a proper moisture level for your home/interior climate which is typically between 6-9% moisture content. Installing hardwood flooring with a moisture content that is too high will cause spaces in the floor when the flooring dries out, and installing a hardwood floor that is too dry will result in cupping when the flooring picks up moisture. If the retailer selling you flooring does not have a moisture meter and can check the moisture for you then I would suggest you run. The majority of people selling hardwood flooring know very little about wood and moisture, if they don't even have a moisture meter, that is a sign that they are not professional and know nothing or very little about hardwood flooring and shouldn't be selling it.

7. What does the supplier recommend for acclimation?

I know you must have heard someone say "the flooring must sit in your home for two weeks prior to installation". This is a very general statement and in most cases will do more harm than good for your hardwood floor. If you did this in a new home and it sat in the home while they were drywalling, painting, the wood would be so damp by the time you installed it that you would just be asking for trouble. The fact is a new home will have 1000 to 2000 gallons of water that will be oozing out of the home the first two years. If your flooring is sitting in the home before it is installed it will absorb all of that moisture. If you are having the flooring sit in your home you will want to make sure it is stored in normal living conditions to avoid it from drying out too much or picking up too much moisture. In some cases, a seasonal dwelling, you may want to have the hardwood flooring absorb the moisture before it is installed. If the home is always a high humidity environment then you want the wood to pick up moisture so it can be normal living conditions for that particular environment. You want to have a hygrometer to measure the humidity in your home before the installation and monitor your humidity after to ensure your home is in the proper humidity range to avoid issues with your flooring.

8. What does the stain/finish look like?

Many large manufactures will finish all different woods at the same time without making adjustments for each wood because each time they make adjustments it effects the production. The fact is, each wood needs to be finished differently to achieve the nicest stain/finish. Oak requires more finish to "fill in" the grain or else it will appear very pitted which is not something desirable in an oak floor. You want to be able to hold a piece up to the light and see a perfect smooth finish. Maple requires more brushing than oak so the stain can penetrate into the wood and not appear "blotchy". Maple is a beautiful wood and with the proper staining you can really bring out features such as Birdseye and tiger tail. If not stained properly these features are hidden.

9. Does the supplier warrant the work done by their installers?

If you are purchasing flooring from a company and having your own contractor install the flooring you want to make sure your installer is a professional. In many cases if you use your own contractor and there is an issue you will have the installer blaming the issue on the hardwood and the manufacturer blaming the issue on the installer. When nobody takes the blame you won't have very good luck getting your issue resolved. If you are buying flooring on a supply and install basis you want to make sure the company warrants their installers work and the installers are qualified. Many stores will sub out their installations to contractors so they really don't have the ability to monitor their work unless they visit every jobsite. You can see a list of certified hardwood installers in your area by going to http://www.nwfa.org.

10. What grade is the flooring?

Comparing flooring by grades can be very confusing and misleading. Many large manufacturers have five or six different grades of flooring so just because brand A has a less expensive product than brand B they may not be the same or even a similar grade. There is really no standard grading system for prefinished flooring so just because the product is labelled "select and better" may not mean it is the best quality flooring.

12 Must Know Things You Need To Know When Buying Hardwood Flooring!


I am about to reveal to you some key facts that hardwood flooring manufacturers do not tell you about and it could save you thousands of dollars on your next hardwood floor.

Being an owner of a third generation family flooring business, I have seen flooring stores come and go all the time. I have seen gimmicks and tricks from manufacturers, representing their flooring products with impressive statistics and new "technologies" to guide people into how "their" product is better than the next. Sometimes the changes in product are actually viable and do work, but others are just plain nonsense.

Let's talk about some things you may not know when it comes to hardwood flooring, both engineered and solid hardwood.

Did you know that wood flooring has a comfort level too? Wood flooring will perform best when the indoor environment in which it is to be installed has a relative humidity range of 35 to 55 percent and a temperature range from 60 to 80 degrees Fahrenheit. This is about the same comfort range that we as humans enjoy.

Let's talk about the first thing you must do as an installer and the home owner. Ready for this...READ THE INSTRUCTIONS FIRST! Before you go gung ho and rip open the boxes, as most men do, take 10 minutes and read the complete instructions for the material provided. There should be a copy that comes in every box of material. Sit back, have a beer, and READ!

Now that we have that clearly understood, you need to INSPECT to know what to EXPECT!

1. Acclimation: The moisture content of the wood and subfloor must be within 2-4 percentage points of each other and the subfloor must not exceed 12% moisture content. The farther the percentage points are away from the subfloor moisture percentage, the more problems you will have. For proper acclimation, material must achieve room temperature (65-80 degrees F) for 24 hours PRIOR to installation. This means that the heat has to be on and working way before you try to install the flooring. To get proper acclimation, store the material according to the manufacturer's directions. The instructions will specify whether to store opened or unopened and whether to store in the center of the room or at the edges. This leads into the next big topic of moisture content.

2. Moisture Content: What is the ideal moisture content of the actual hardwood product? Every manufacturer will very slightly, but the average approved moisture content in the hard wood flooring itself should be between 6-9%. For example, if the moisture content of the subfloor is 12% and the hardwood flooring is 9% there is a 3% difference between the two wood products, which is in the allowable tolerance of installation. Although some movement can be expected even in this range, dramatic expansion and contraction can happen outside of these measurements. There are several electronic moisture meters available on the market to test the moisture content of the hardwood and subfloor. These are generally a pin probe type meter and they can give you an immediate reading of your wood's moisture level. It is very important that it is set to the species of wood that you are installing and that you take moisture measurements from several boxes of material and from several areas of the subfloor throughout the area that is to be installed.

3. Climate Control: Climate control might be the single most common reason for customer dissatisfaction with their hardwood purchase. It is CRITICAL, that the proper temperature and humidity level be maintained throughout the life of the hardwood installation. Improper climate control will result in the material swelling in the summer and shrinking, or gapping, in the winter. Without proper climate control within the house, gapping and shrinking will definitely occur. In the Northwest we do not have a huge problem with this issue unless there is a device used in the home which dries out the air to an extreme amount like a wood stove. This is why a pot of water is ALWAYS recommended to be kept on the wood stove when using it as a heat source. The pot of water keeps moisture in the air. Special Note: Some products that are constructed with HDF cores, are more stable and less prone to expanding and contracting.

4. Floating Floors: A key thing people miss when installing floating floors is to allow for an expansion gap around the room. Just as real dimensional lumber expands and contracts, so does your floor. There must be enough space left at vertical surfaces, like walls and posts to allow for this movement. The larger the area the more space that is required. Rule #1 - Always leave the required expansion gap called for by the manufacturer. Rule #2 - If your installer says that it is not necessary, fire them and refer to rule number one.

You can cover all expansion gaps with wood wall base or quarter round wood trim or a combination of the two.

5. Expansion Joint: Expansion joints are almost always required between rooms, where a room meets a hall or in large expanses. You can use a "T" molding in these areas to allow for the floor expansion and contraction.

6. Moisture Control: Here is a big one! Moisture in the subfloor, called "hydrostatic pressure or vapor emissions", is a MAJOR reason for flooring failures. The subfloor is not to exceed 65% relative humidity. There are several moisture meters that can be used on the floor that provide accurate readings, or a calcium chloride test, used for "concrete floors". If your wood subfloor is above 12% with a meter, do not lay the floor. If your wood subfloor is above 12% then you have to find out why - it could be a new floor and just needs to dry out. If you have concrete floors, you have to find out the source of the moisture. If you still cannot figure out why the floor is above 12%, don't use hardwood. Period. I mean it...you will kick yourself. If your floor is ok to install, remember to always float an engineered floor over 8 mil plastic when going over concrete so as to eliminate and minimize water vapor coming through the concrete floor.

7. Glue down Flooring: In residential installations, most flooring that is engineered is either click together or tongue and grove. I don't think I, personally, would ever glue down an engineered floor. It is an acceptable way to install but I find that it is terrible to rip out years later. Either glue it together or click it together but don't glue it down to the subfloor unless you have a very specific reason to. I have seen more problems even stapling it down to the subfloor. Stapling down your engineered floor will just lead to squeaks and creeks that will drive you nuts. Pull out the instructions that you threw in the garbage and look up the manufacture's installation methods, then go file the instructions with your purchase receipt for future reference.

8. Nail Down Flooring: A very common mistake we have seen in solid flooring installations is proper nail length, gauge of the nail, and spacing between nails. Always refer to the manufacture and double check the subfloor thickness. When using a pneumatic nailer, pay close attention to proper PSI settings.

9. Natural Product Variations: One of the inherent beauties of hardwood is the differences between boards and how much or little they accept stain. No two pieces will ever be alike and that is one thing that makes wood flooring so luxurious and realistic compared to laminate flooring. Pay careful attention to the layout and selecting the color and grain of each board when you are working with the product. Work out of 4-5 boxes at a time when doing a layout, this will randomize any variations between boxes of hardwood.

10. Culled Material: In every natural product like wood, there will be some pieces that, while not defective, and within industry standards, are not what the consumer, you, wants visually. Generally allow for 5-10% waste factor on material. This means that you need to buy 5-10% more material then what your job physically measures out to be. Larger jobs of 1000+ sf could work with 5% while jobs under that square footage can figure 10%.

When buying material from the "Big Box" stores you have to keep in mind that when they purchase materials for a "stocking special" they purchase a product that they can sell at the lowest possible price to use in their ads. This means that the hardwood that they pick up is "Tavern Grade" which means it does not meet the specs of normal running line material. The product will have more voids, mis-filled holes in the face of the hardwood, warped boards both side to side and up and down, and broken toungs. This product will have a lot more waste factor to it, even as much as 20-25% compared to the professional flooring stores stocking inventory. Buyer beware, what you could think is saving you that 10% difference in price, could be costing you 20-25% more in having to buy more wood for the same size job. Oh, and by the way, always keep 1-3 full boxes of material for doing repairs. Do not return them to the store. You will NEVER be able to match the floor again should you need to. Paint would fall into this same realm of thinking. When you need to touch up a wall, they will NEVER be able to exactly match the color. In hardwood there is not only color to match but grain of the wood, board width, color and the number one factor, gloss level of the hardwood or "luster".

11. Scratches: All hardwoods scratch - it's a fact of life. You just cannot change it. You will scratch, scuff, and dent your hardwood under the right conditions. Scratches occur more frequently under chair legs that are small in diameter and at entry areas where abrasion dirt is tracked in on the bottom of shoes. The industry has developed more scratch resistant surfaces like those containing aluminum oxide, they tend to show less scratching but the wood still dents under pressure. To help save your floors use felt chair protectors under all of your free standing chairs. Area rugs are great for rolling chairs in the kitchen, or replace the cheap plastic wheels with rubber barrel casters. The more expensive casters will spread the weight of the chair out more efficiently. The best first line of defense is an area rug by the front door or a tiled entry way to catch the dirt and sand "before" it gets dragged across the hardwood floors. Good rules of thumb, shoes get checked at the door.

12. Cleaning: For heaven sakes ask a flooring professional! Your wood floors are tough but they are delicate when it comes to moisture and cleaners. Throughout this article we have talked about moisture, now we don't want to ruin the floor by trying to maintain it improperly. Follow the manufacturer's instructions.

DO NOT: Use a wet mop system, a steamer, a bucket and mop, any "Wax" finish, no soaps, no polishes, and for heaven's sakes do not over wet your floor with a wet mop.

The best way to clean your floor is to use a microfiber mop and spray a professional hardwood cleaner onto the mop head, to dampen the head, and then clean your floor. If you see streaking or a wet trail, you have used too much cleaner and immediately wipe up the excess with a terry cloth towel.

If you treat your hardwood floors with the love you would treat your wood dining room table, you will be happy for years to come.

Installing Hardwood Flooring Over Concrete and Wood Sub Floors


Expansion & Contraction of Hardwood Flooring

"The flooring shop said to leave 10mm for solid wood floor expansion at the walls...now the boards are lifting off the floor." Ill informed advice like this often leads to floor problems. Many flooring sales people unfamiliar with solid wood flooring assume expansion is the same as laminate flooring. In reality that 10mm is not enough for solid wood flooring.

What Is An Expansion Area? Why Do We Need It?

Expansion areas are spaces left around the perimeter of rooms, against fixed objects such as columns, thresholds, hearths, skirting boards, and other stationary items built or secured into the framing structure of the home. Even though Hardwood flooring used is no longer living and breathing it still reacts to moisture changes in the environment. The cells in the solid wood will take on or absorb moisture when the relative humidity is high, or when exposed to water. Expansion takes place, and the hardwood grows, for lack of a clearer term, across the grain (width) of the plank (see below, not all will react this way). Conversely when air moisture levels decrease, moisture content evaporates, shrinking of the solid wood will occur.

When we say spaces, they are defined as installing the hardwood flooring up to and away from the fixed objects. For example; "we recommend at least 15mm small to medium area-18mm expansion on larger areas at the skirting board or wall if new skirting to be fitted."

Hardwood flooring can react to the presence of moisture. In the dry winter heating months, moisture can leave the wood flooring causing the floor to contract slightly in size, which can leave slight gaps between each floor board. In the summer months when the humidity is higher, the hardwood flooring will expand and the gaps will disappear. If there is too much moisture in the subfloor it will cause the wood planks to cup, or buckle. Nearly all problems related to hardwood flooring are due to improper installation and sub floor preparation. This is why it is important when installing hardwood flooring that you follow the correct recommended installation methods by the manufacturer.

Direct Glue Installations

A direct glue installation requires the use of a flooring adhesive applied directly onto the subfloor (never directly apply to the boards). This method can be used on concrete and wooden subfloors. When done correctly this is the most stable method for fitting solid wood flooring as the elastic flooring adhesive allows the floor to expand and contract with no problems.

If you are laying over a concrete subfloor you will first need checked the concrete moisture, if the floor has a moisture content of over 4% then either wait until the sub floor dries to meet this level or use an appropriate moisture barrier, we recommend Sika Mb Primer to ensure no damp rises up into your new floor.

Also note that new concrete slabs require a minimum of 60 days drying time before covering them with a wood floor.

All Concrete sub-floors must be dry, smooth, level and free of structural defects. If the concrete sub floor is uneven we recommend using sika latex self leveling compound to level the subfloor. The concrete must also be free of contaminants i.e. paint, oil, wax grease, dirt and curing compounds (the reason for this is that you need the self leveling compound to bond to the sub floor).These may be removed chemically or mechanically as your local hardware store and they will sell you the correct floor cleaner, but do not use solvent-based strippers under any circumstances. The use of residual solvents can create problems with the bonding of flooring adhesives. It is important to ensure a proper bond between the adhesives and concrete and wood panels.

If you have a wooden subfloor you will need to lay a plywood base over the existing floor boards (we recommend using 4mm -6mm exterior grade plywood and screw down every 15cm along the edges and at 20cm intervals throughout the rest of the board using the 1 inch deck screws) before installation, this will then give you a smooth and level surface for you to install you hardwood flooring onto.

You will need to leave a 15mm expansion gap around the perimeter of the room for large areas over 6 meters in length we recommend 18mm expansion gap. To maintain this gap during installation spacers are provided in the kits. After you have installed the hardwood floor you can cover this expansion gap with scotia or new skirting boards The 15mm expansion gap also needs to be left in doorways where the hardwood floor follows through from one room to another we sell on this website a full range of door profiles available to match your floor.

Nailed Down Installations

Nailed down installation is the traditional way to install hardwood floors and can be done either directly onto wooden subfloor or on a concrete subfloor with the use of battens. When fixing battens onto concrete you will need a power-actuated nailer to drive through the battens and fix directly into the concrete, firstly lay out polyethylene moisture sheet then plywood over the battens to create a new sub floor. We recommend 12mm exterior grade plywood and 2inch x 4inch battens. Lay battens around perimeter at ½ inch from the wall, leave ¼ inch gap at each end. Position the first batten so its centre is 16 inches from the outside edge of the perimeter batten. Lay out the remaining battens across the area 16 inch intervals. Always check you battens are level using a level gauge you may need to use cedar shims to level out dips in the concrete, slide the shims under the battens until level. (If in doubt we recommend consulting a professional fitter for this method).

Wooden Subfloor

Hardwood floors can be nailed into existing wooden subfloors such as floorboards or plywood but not into chipboard floors as these are not strong enough to hold the nails. The floorboards must be in good condition and level if not it is advisable to lay 6mm exterior grade plywood down first.

To avoid creaking, check over the subfloor and securely fasten any loose floorboards. For added soundproofing it is also advisable to use a standard foam underlay.

When you nail down a solid wood floor you use a Porta Nailer to drive a nail at a 30 degree angle through the tongue and into the subfloor. Porta Nailers can be hired from any good hire shop but are expensive to buy.

Again you will need to leave a 15mm expansion gap around the perimeter of the room. To maintain this gap during installation spacers are provided in the installation kits.

After you have installed the floor you can cover this expansion gap with scotia or new skirting boards.The 15mm expansion gap also needs to be left in doorways where the floor follows through from one room to another; we sell full range of door profiles available to match your floor on this website.

WASTAGE

When ordering your new floor we recommend you allow for some wastage due to cuts a professional fitter would add on an extra 2%-5% of flooring needed to finish a job. We recommend non professional fitter should add on 5%-10%.

Preparation For Wooden Flooring


I don't think many people actually ask where the wood for wooden flooring comes from. "Trees" would be a fairly obvious answer, to be sure, but believe it or not, it's actually not that simple. Wood is something we're all familiar with; it's in your walls, on your tables, holding your computer up, and probably even holding your butt up as you read this article. Obviously wood is a natural fiber that is manufactured from the stems of large trees, but if you're interested in wooden flooring, there is a bit more learning you should do on the subject. For one thing, you should only ever use treated wooden flooring. This is because the cellulose in the stems of the trees transport water and nutrients from the roots underground up to the leaves above. Untreated lumber will absorb the water from any humidity and will then expand because of it. Although this swelling effect is good for trees, it's not at all good for your wooden flooring, and will eventually lead to costly repairs, if not all out replacement. What good is wooden flooring if it's not going to be a very long lasting floor? That's half the beauty of it; don't spoil it by going cheap with untreated lumber. Treated lumber is the only way to go.

You should plan to receive your lumber at least a few weeks before you plan to actually put it down on the floor in the form of wooden flooring. There will be certain ways of storing the wood that must be followed, depending on the local climate conditions and temperatures. Your lumber provider should be able to give you details on this when you purchase your lumber. Daily fluctuations in temperature and humidity can also affect your wood, but there are plenty of humidity monitors and temperature meters out there to help you keep track.

You'll also likely be using either concrete or drywall, if not both, along with your wooden flooring. It's important that the flooring lumber not be placed anywhere near your drywall or concrete until they are completely and totally dry. As mentioned above, wood floors and humidity do not mix happily, and the bottom sides of the lumber may not be treated, or treated as well as the tops, so before your wooden floor is actually a floor it's particularly vulnerable. A common method of checking to see if the concrete or drywall is dry is placing a clear plastic sheet on that area for a few days and making sure the sheet remains dry. A dry plastic sheet means it's safe to install wooden flooring.

Pay special attention to the area that you place your lumber for the duration of the process known as acclimating. Any areas with high moisture under the flooring or behind the walls should be avoided. Also be wary of any appliances or space heaters as they can affect the readings of the monitors and meters you are using to keep track of the climate around your lumber. The last thing you want to do is go to install wooden flooring, only to find that that lumber is ruined simply because you stored it in the wrong place.
