So, I’ve been working on this house prepping the sub floor prior to the new wood floor install. I have cut 48 sheets and loosely installed. After all were cut and put in place, the next step was to remove each sheet, apply glue and screw down. In the 2 days since starting this work, I have noticed that the plywood has become slightly crown shaped acting like a cushion of air is underneath.
Now, the plywood has been on site for about 6 months, but stored in pallet form thus in dry storage. However, laying the sheets over the radiant heat has dried the wood even more.
Moisture testing proved my theory. On the bottom side facing the heat source the moisture is 2% lower than the side up, or side away from the heat. As the side is dried it shrinks and gets smaller. The up side is slower to dry thus creating the warped plywood.
Again, Acclimation! Acclimation! Acclimation!
