Q: If my hardwood floors were installed poorly…. My hardwood is glued directly to concrete, no vapor barrier, and there is no 1/2″ gap between floor and wall. How much moisture is needed to cause cupping, or worse, buckling?
A: If the moisture in the floor or coming up through the concrete is higher than the moisture content in the flooring when it was installed, it will impact the floor. That is why there are products and procedures to block or retard moisture movement, so it doesn’t hit the wood floor in one continuous stream.
