Hardwood flooring installation options: glue
Just as there is more than “one way to skin a cat,” there are also many different methods homeowners can choose for the installation of their solid hardwood flooring. Those who decide to glue down such flooring often do it for practical reasons, such as when the hardwood must be installed on top of a solid concrete surface.
To be sure, it is possible to first lay down a wooden subfloor and then nail or screw hardwood planks to the top of that, but this method has drawbacks. It is laborious, it adds to the ultimate installation cost of the hardwood flooring itself, and it will cause the floor to be raised higher than homeowners might find optimal.
Considerations for a glue installation over concrete
This is not to say that deciding to glue a hardwood floor on top of concrete is a simple matter. Indeed, it requires careful planning ahead of time. The type of board used must be as stable as possible; many hardwood specialists recommend using only boards that are quarter-sawn. In addition, moisture absorption can be an issue, causing wood to swell and shift position. The solution for this is to use a urethane finish on the boards – one that is designed to promote moisture curing.
With these considerations in mind, it is possible to use a glue-down method over concrete. However, due to very high moisture levels in cellars and basements, it is recommended that the glue-down method be used only above ground level.
Remember that in time your beautiful installed hardwood floor will need some form of floor sanding services to keep it looking as good as new.
