Glue solid wood floor to concrete.

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. Solid hardwood should not be glued to a concrete slab. Glue is a secondary method of attachment for bonding wood to concrete. The only limitation is the slabs must be above or on grade.

When glue is used in conjunction with screws and nails the bond is strong enough to resist natural movement of the wood. 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. Wood needs to move as the humidity increases and decreases throughout the year.

These products regardless of species thickness or width can be glued down successfully over concrete or gypsum based sub floors. Be advised that over strapping can adversely affect the floor and may result in glue bond failure seam peaking twisted boards or out of square floor board alignment. If the wood can t expand sideways it will twist warp or cup as it absorbs moisture. When affixing wood to concrete one of the best and easiest methods is to glue the wood to the concrete with epoxy.

Installations of solid wood are never recommended below grade. Although you can attach hardwood directly to concrete with glue or nails it s not advisable.
