It can be difficult to know exactly how much glue to use when laying hardwood floors over concrete.

There are many variables to take into account and the answer will differ from project to project.

Luckily, we can help you understand these factors.

Knowing the importance of subfloors and the differences in adhesives will help you pick the appropriate product.

This article will also list the benefits of using an adhesive over nails or using a floating installation method.

Why You Might Want to Use Adhesive

Using a bonding agent to glue down your hardwood flooring is a popular installation method. It's quite easy to do and can be quite cost-effective too.

The result can be more stable than using floating floors or nailing down the hardwood. Of course, for the best results you might still want to hire a professional.

Requirements for Gluing Hardwood Floors

You will need to shop around for adhesives but that's not the tricky part. Gluing a hardwood floor requires either a concrete or plywood subfloor. Obviously concrete will give you a more stable result but there are some things to consider and be aware of.

If your subfloor has any moisture it will eventually rise into your hardwood floor, causing annoying and visually unappealing lumps. No matter how strong your adhesive is, it won't protect you from a damp subfloor.

The same applies if you're gluing hardwood flooring to a plywood subfloor. No matter how much glue you use, a less-than-perfect plywood subfloor will have a serious impact on the top flooring.

How Much Glue Should You Use for Hardwood Floors?

Contrary to popular belief, there is such a thing as too much or not enough glue. Different types of hardwood react differently to adhesives. The strength of the glue is also important.

Cutting corners to save money on glue is not something you want to do. This is especially true if you plan on keeping the hardwood floor for years to come.

So how much glue do you need for installing hardwood floors? Unfortunately, this depends on the brand or formula of the adhesive you choose. The exact amount you need to use should be specified on the label by the manufacturer.

It should also mention how much glue you need for each specific wood thickness and type. Since these adhesives are quite specific, try not to use less. Going a bit over the recommended amount is better than not using enough.

You should also check if a vapor retarder is required for the subfloor. That may not always be the case but it is possible, especially if you're installing 3/4" hardwood on concrete.


The amount of glue you need for installing hardwood flooring varies on a project by project basis. Not all rooms are the same and not everyone uses the same wood, tile thickness or adhesive.

It will also depend on whether you're installing your hardwood floor over concrete or plywood. To find out the exact quantities, you should check the label of the glue bottle for the guidelines you need. Also, remember to consider a vapor retarder if you're using 3/4" thick solid wood tiles on concrete.
