Installing Bamboo Flooring

Before installing bamboo flooring, watch an installing bamboo flooring video; you may decide to hire a professional for installing your bamboo floor. There are tricks for bamboo flooring installing that can make the job faster with better results. Installing bamboo floor over fir floor with no subfloor isn't much different than installing over plywood or OSB subfloors. If installing floating bamboo floors over slab subfloor, take extra care so you have great results -- or again, hire a professional. Bamboo flooring is beautiful and durable, and very much worth your consideration. Installing bamboo flooring isn't hard, but hiring a professional is worth your consideration.

Installing bamboo flooring over a wood sub-floor is no more difficult that installing other wood flooring, and many homeowners find self-installation to be a great way to save money. However, installation over concrete takes more skill and expertise, and may not be worth the money you'd save by installing it yourself. Before you begin the project, it's important to assess your capability and motivation to do the job yourself.

Once you've committed to installing your bamboo floor, make sure to order an additional 7-9 percent flooring to allow for waste and cuts. Also, carefully examine the bamboo flooring for consistent color, finish, quality, and damage before you begin. As with all projects, read and have a thorough understanding the manufacturer's installation instructions, policies and warranties because the time spent in these early stages can greatly improve the quality of your finished product.

The basic concepts for installing bamboo flooring are the same as for installing other hardwood flooring. The sub-floor must be flat, smooth, clean and preferably dry -- especially if installing onto a concrete surface (and you probably should consider laying a vapor barrier between the sub-floor and bamboo. Most bamboo floors are not covered under warranty if installed in a bathroom, washroom, saunas, or other similar wet locations -- but check with the manufacturer you want to choose to make sure. Remember, bamboo flooring is a natural product that will warp or swell with extended exposure to moisture, and shrink with extended exposure to heat.


General Preparation
   

  • Acclimate: As with other hardwoods, bamboo flooring must be acclimated in the room where it will be installed for 24-72 hours to ensure it adapts properly to the temperature and humidity level of the room. If you live in an arid zone, it's advisable to have the wood acclimate in the space it's to be installed for even longer; you want the wood to be at about the same moisture content as the humidity level in the room.

  •    
  • Lay-Out: By laying the flooring prior to installation, you can ensure that the floor color and grain characteristics enhance the beauty of the finished floor. Being a natural product there will be variations, and the finished floor looks better if you intermix the light and dark pieces, as well as the slightly different grains.

  •    
  • Warranty: Follow the manufacturer's installation instructions to protect your warranty.

  •    
  • Tapping Block: To avoid fracturing the flooring edge, use a tapping block to hit the bamboo, or a rubber-headed mallet. Never hit the bamboo flooring directly.

  •    
  • Base Molding: Remove any base molding (aka baseboard or toe kick) and door thresholds before installation. Leave 1/4-1/2" expansion space between walls, cabinets, etc. using plastic or wood spacers to accommodate expansion due to changes in moisture level. These spaces will be covered when base moldings are reinstalled.


    Wood Sub-Floor -- Additional Preparation
       

  • Clean and Smooth Surface: The wood sub-floor must be clean and free of all wax, grease, paint, etc. To ensure a smooth, even surface, sand the wood sub-flooring, and remove dust with vacuum and damp rag. If the floor isn't level, sand down the high spots and fill in the low spots.

  •    
  • Secure: To eliminate squeaks, nail or screw the sub-flooring every six inches. This is well worth the effort because squeaking floors are a nuisance.

  •    
  • Moisture: As recommended by the manufacturer, add a moisture barrier.

  • Concrete -- Additional Preparation
       

  • Clean and Dry: The cement must be clean and free of all oil, stains, dust and debris, and must have all cracks and holes filled with patching material. Do not install on concrete unless it will stay dry during all seasons. Using a moisture meter, check the moisture levels in both the concrete and bamboo flooring. The difference between the two must be less than 3 percent (or 3 lbs. per 1,000 square feet, using a calcium chloride test).

  •    
  • Moisture Treatment: Treat for moisture per the manufacturer's recommendations.

  • Vinyl -- Additional Preparation
       

  • Clean and Dry: Make sure the vinyl is in good condition, clean, level and well bonded to the sub-floor.

  • Installation

    Once your sub-floor has been prepared, your working line can be established by measuring an equal distance (the width of the plank plus 1/4" for expansion) from the wall at both ends. Once measured, snap a chalk line. Confirm your working line by laying a few rows without glue or nails.

    The three primary methods for installing bamboo flooring include the nail-down method, the glue-down method, and the floating method. Typically, the nail-down method is used with wood sub-flooring, the glue-down method is used for concrete sub-flooring, and the floating method is used for radiant heat floors, though nail-down can also be used on radiant heat floors too.

    The use of each method depends upon the sub-flooring and the manufacturer's recommendations. Regardless of the method you choose, it is vital to follow the manufacturer's instructions because they vary from company to company, and variances from these instructions may void the warranty.


    Finishing

    Bamboo flooring can be purchased either pre-finished or unfinished. If you've installed unfinished flooring, sand the flooring using a floor sander as you would any other hardwood surface. After sanding the floor with a coarse grit, repeat with a medium grit and finish with a fine grit paper. Directly after sanding, apply the first coat of finish to avoid moisture absorption. Apply additional coats as recommended by the manufacturer, and as needed for traffic. Pre-finished flooring is ready to use immediately.


    [Note: pre-finished bamboo planks have beveled edges so that as the imperfections of milling come into play, you won't have ridges between planks. One advantage of unfinished bamboo flooring over pre-finished bamboo flooring is that the sanding done after the bamboo installation is complete smooths all plank edges. Then putty can be applied to any gaps, caused by the imperfections of milled wood, before the finishing coats are applied, giving a smooth surface to your new bamboo floor. With a smooth floor, there are no cracks or gaps to collect dirt. And, damage happens as bamboo is installed; there is minimal recourse with pre-finished bamboo, but with unfinished bamboo the sanding will take care of the nicks and scrapes that can happen.]

    Hi Steve,

    I know somebody who has bamboo flooring, I'm hoping she'll be a long in a bit to chime in on this one.

    I'm thinking it has to do with the nail gun and the nails being used, so I did some google-ing to see if I could find an answer. You can do the same as well. ;o)

    Look at this thread by clicking here. Some folks have really done their homework there.

    Hi, great site! I am installing Morning Star Horizontal carbonized in my walk-in closet and bathroom sink area (separate from shower area). Well the floor I did first is in the walk-in closet and it is perfect. The floor I just installed yesterday in the sink/hallway area snaps like an old house! No squeeking, snapping or popping. In the walk-in I used a staple gun from H.Depot, but I hand nailed the rest of the floor in the sink area. I spaced the nails 2" apart. Should I have used a staple gun to secure the boards? Thanks for advice!

    Hi John,

    Most likely. Another thing to think about: how level was the area that you installed yesterday before you put down the Morning Star flooring?

    hello, what type or kind of nail do I use? exactly where does the nail go on the tongue part? do you have any ideas for the baseboard to use with the bamboo?

    cannon at July 29, 2008 11:28 PM


    Hi Cannon,

    Sounds like you need to visit the manufacturer's website or a DIY (do-it-yourself) website for detailed instructions. You can call the manufacturer too. Most installers use nail guns. A lot of people hire a professional for bamboo flooring installation because it tends to split, chip, splinter, etc. during installation. You can do it yourself, so long as you take the time to learn about it first.

    Remember, it is vital to follow the manufacturer's instructions because they vary from company to company, and variances from these instructions may void the warranty.

    Hi Cannon, I checked with a friend of mine who had bamboo flooring installed, and the installers used a staples (with a staple gun) for the T&G and something akin to finish nails where they couldn't access the T&G. She also made the comment that installing bamboo flooring is best left to professionals, in her opinion, due to the reasons I mentioned in the post above. At least that way, if it gets screwed up, it's not your fault but the installers.

    Oh, forgot to address your question about baseboard. Any baseboard that's thick enough to cover the expansion gap will work, and choose something that fits your home decor. I know, not much help, but you didn't include information on what kind of colors you're using, or if you want the baseboard to coordinate with the walls or the floor. ;~)

    Hi, We had a guy install bamboo flooring in a small bedroom by glueing to concrete floor. Gorgeous result, beautiful hardwood floor. BUT--the bamboo apparently got permanently stained on its surface, by his hands during the process. (fingerprint marks, etc.) I don't know how to get them off. Plus, the stains are not glue but I think they are a glue by-product like oil, sweat, dirt, glue vapors, etc. Even if he wore gloves (which he should have), how to prevent glue vapors from imprinting the bamboo when installing in the future? He has to touch the bamboo surfaces during install. DIY folks say 'wipe down' during install to prevent all this; but I am not sure plain water will do it, if it is glue vapors...what to use during install to wipe down?!?!? HELP!! Thanks

    You can try using a vinegar/water mixture and see if that takes care of it. If it doesn't, then it's time for a delicate operation -- cleaning up the glue. With great care, gently dab mineral spirits onto the glue until it comes up. Be careful to not get too much on the flooring surface so you don't damage the finish. Be sure to wash the spots with clear water when you are done to remove all remnants of the mineral spirits.

    When the glue in removed you may have to buff the fingerprints with a soft cloth-- if they are just body oil and not glue smudges -- to get the clean surface you want.

    I've also heard of a more unconventional approach for adhesive residue - don't know if it works on other problems, like those from body oil, etc. Use a small amount of "Goo Gone" and "Bon Ami" on a paper towel and gently rub with the grain over any traces of adhesive. Quickly wipe off the mixture with a slightly damp towel and then thoroughly dry. Bon Ami is a mild abrasive that mixed with the Goo gone is just enough to do the trick. You may notice a slightly less shiny appearance after using this, however it is not enough that anyone but you would notice. Certainly much better than the smudged adhesive look.

    If the glue was latex based, you might try using a SOS pad - not the steel wool ones, but the kind made of plastic fibers. There's two kinds, the kind for tougher scrubbing and delicate. Use the delicate. Sometimes this works. Don't scrub hard though and be sure to take a damp rag to clean up afterwards or microfiber cloth. You can also use a dry microfiber cloth to kind of 'buff' it afterwards.

    You can also call the manufacturer - I'm sure they've heard of this numerous times and can also make recommendations.

    How do you fill in gaps in a pre finished bamboo floor? Two weeks after installation I noticed a 1/4 inch gap running the length of my floor and ther minor gaps. The floor was installed in the cold weather. Now that it is warm the gap has closed a little, but is still noticable as it is in the middle of my living room. The inspector said it is not the floor, but the installers liability. They suggest filling it in with putty, but I am concerned about the putty cracking and needing replacement over time. I am wondering if the best thing to do is to have the floor replaced even though it will be difficult?

    Hi ksmith,

    I would suggest giving the installers a call, and perhaps even the manufacturer. What brand did you use (just out of curiosity).

    I agree with the inspector, it should be the liability of the installer - the size of the gap in unacceptable. I wouldn't do anything yourself yet. The floor would still be under warranty from the manufacturer, what kind of warranty (if any) did you get from the installer on their work?
