I was going to build something that required one sheet of 3/4” prefinished birch plywood and one sheet of
The dilemma : I only needed a half a sheet and my supplier had one that was starting to “delaminate” on the edge. That’s OK, I only needed half of it length-wise. What I did not realize was that this was no ordinary plywood. It looked great, an Alder veener plywood. I got this $60.00 sheet for only $20.00. Great deal huh?
What this piece of CR was is 1/4” 2 ply DF core with 1/8” MDF on either side. It was not delaminating, one of the MDF layers was separating right down the middle. If you put this CR length-wise between two saw horses and cut it length-wise, the WHOLE thing “delaminates”. I now have 4 sheets of 2’ x 8’.
The good news is the supplier is refunding my money and doesn’t want the PLYWOOD ? back. My neighbors house is all done in alder inside. He might line some closets with it or something.
This stuff (when carried flat and unsupported) bends in the middle from own weight and IT FAILS.
