mtaylor Posted August 26, 2019 Share #1 Posted August 26, 2019 I have some "Lite Ply" that's been sitting in the workshop for about a year. The A/C or heat has been on and windows closed (allergies). Yet it's warped a bit. Is there anyway to prevent it from warping? It's 1/8" thick, 3-ply. My concern is that I have more on the way for my new build and if it's going to warp, that's a real problem.

Chuck Posted August 26, 2019 Share #2 Posted August 26, 2019 It always happens to me too. I keep a heavy flat weight on it. Several large heavy stones. This helps but there is still warping at times.

Chuck Posted August 26, 2019 Share #3 Posted August 26, 2019 If you wet it...only wet one side. I forgot which side you are supposed to add water to. Then flatten and leave in the sun.

CDW Posted August 26, 2019 Share #4 Posted August 26, 2019 All I know is, it's easier to prevent warping than to correct warping. Storing it on a flat surface with a flat weight on top has kept it flat for me. Without it, it warps. mtaylor and Canute 2 Quote Completed Projects: USS Fletcher 1:144 Scharnhorst 1:350 USS Independence LCS-2 1:350 1:32 J7W1 Shinden Interceptor/Fighter Fairey Swordfish Mk.

mtaylor Posted August 27, 2019 Author Share #5 Posted August 27, 2019 Thanks for insight everyone. I'm testing on my available stock while waiting for my order from National Balsa. Seems that the smaller cut pieces don't warp like sheets. By smaller, I'm looking 12" X 12" whereas my 24"X24" did warp. Both were stored in the same place. When the fresh comes in, I'll keep it flat for few days on the dining room table and then cut it down to manageable sizes.

reklein Posted August 28, 2019 Share #6 Posted August 28, 2019 Maybe you could use flat concrete pavers from HD. I would use stickers,small wooden strips , between the concrete and the ply though.
