Glue Solid Wood Floor To Concrete

The other concern has always been that water in a concrete slab will be absorbed by wood flooring.

Glue solid wood floor to concrete.

Glue forms the initial bond but without screws and nails the natural expansion and contraction of the wood can break or weaken the glue. In this case the subfloor is the concrete slab. Solid hardwood should not be glued to a concrete slab. Engineered hardwood is perfectly suited to do the job and there is no reason to glue down solid hardwood.

I have seen some major disasters because someone who lacked experience did exactly what this post suggests and ended up with a 16 000 failure in no time. If the wood can t expand sideways it will twist warp or cup as it absorbs moisture. It comes in a caulking tube and is sold at almost. Then you are on your own with a cupped floor that no one will cover any warranty.

Glue is a secondary method of attachment for bonding wood to concrete. The only limitation is the slabs must be above or on grade. One suggested glue is pl 400. There is no valid reason to glue a solid floor to concrete there are plenty of good engineered floors on the market the rh in the home must be maintained or it will cup.

Wood needs to move as the humidity increases and decreases throughout the year. Although you can attach hardwood directly to concrete with glue or nails it s not advisable. When affixing wood to concrete one of the best and easiest methods is to glue the wood to the concrete with epoxy. I have seen some glue down 3 4 solid hardwood floors directly to concrete and many installers use straps or clamps in an effort to force board rows tighter together during installation.

Installations of solid wood are never recommended below grade. These products regardless of species thickness or width can be glued down successfully over concrete or gypsum based sub floors.
