Preventing veneer from curling
In the past I've used veneer very sparingly and only on tiny pieces (box lids); no problem. I just tried my first larger piece (cabinet back), and had to use 4 pieces of veneer aligned properly... It all went to^&$^#!
I put PVA glue down on the plywood then placed down the veneers. My expectation was that I would get a few minutes to align them, flatten them, etc, before pressing them down (heavy marble pavers).
However, within seconds the 4 pieces began to curl away from the backing and wouldn't stay down. I ended up scrambling to weigh them down, not being sure whether I managed to get out all the "bubbles" etc. I assume the glue introduced moisture which caused this.
Next morning, I could see that there were gaps, bubbles, it was all crap.
What can I do to prevent (or at least deal with) this next time?
Thanks!!
