I am finishing my basement. I purchased about 10 PT 2x4x12's and 10 in pine for top and bottom plates. I hand-picked each stud to assure straightness and stored them flat on a concrete floor. A week later I went to use them and about half of them were either bowed, crowned or twisted. What happened?
Hi bobkat, all that I can tell you is that storing wood on concrete is not a good idea. I don't know if it's the coolness of the concrete, or moisture exuding through the concrete, or a combination of both. What I've done in past years is simply to flip the boards over and let them warp back down the opposite direction. It'll take some of the bowing out and make them a little more straight. For future reference make some kind of raised area (shelving) for storing lumber, after all when you go to the local home center you don't see boards sitting on the ground. Good luck!
