Laying wood flooring on concrete

Get the right materials

Engineered wood is a newer type of flooring that has become one of the most popular choices for covering high-traffic areas like basements and entryways. This style usually has an extra layer in between the top layer of wood and the bottom layer of wood. Engineered is somewhat similar to laminate, but it’s engineered to look more natural than laminate. The good news about this type of flooring is you don’t have to worry as much about cracks developing over time since there are several layers holding everything together.

Most types of engineered flooring will require you to use a special underlayment called thinset mortar or adhesive if you plan on installing concrete or tile. This type of flooring hasn’t been around very long though, so it’s still recommended to ask the manufacturer if you should use adhesive. If you’re installing your wood floor over top of existing tile, it’s also a good idea to talk with the manufacturer about installation methods for this application.

Install on a clean, dry surface

If you are planning to install the best carpenters glue over concrete in a basement or other finished area, then most likely you will need a special subfloor instead of just regular plywood. If this is the case, be sure to seal and paint all areas where water could seep through onto your wood floors from underneath as any moisture can cause mold problems down the road –– which may be very expensive to repair later.

For a finished look, most folks choose to seal with polyurethane. Again, keep in mind that it’s important to make sure you check with the manufacturer about using this method since some may not recommend it.

Your new wood floors won’t be “floating” on top of your concrete if there is moisture below and even though 99% of the time this will never happen due to well-sealed subfloors, you still need to make sure any nearby walls or framing are sealed too. If water ever seeps through them onto your new floors from underneath, then even if they’re completely flat, they could still possibly bow upwards over time or develop cracks along the bottom edge –– which isn’t very safe for anyone walking over them.

Before you get started, be sure to tape off any areas adjacent to the concrete that is painted or finished so they don’t get damaged during installation. Tape and trash can liners are your best friends while doing this type of work because it makes clean-up much easier afterward.


If you don’t have a lot of experience with installing flooring, then I’d recommend hiring a professional installer if you want things done right –– unless you’re up for the challenge! A good place to start is at Home Depot where they will have a handy ” how-to” guide posted on their website which gives general instructions based on the type of flooring material your shopping for .

I wish you all many happy years of enjoying your new floors!

Have a great day!
