Tightbond cold press veneer glue.

Furnished content.
(from WoodNet.net)


I usually use UniBond 800 glue when gluing shop cut veneer or laminations.
I ran a little short on this project so I picked up some Tightbond CPV glue.
I have never used it before.
I did a couple of door panels this morning and put in my vacuum press.
The directions said they should be pressed45 min to 2 hours depending on conditions.

Two hours later I release the vacuum and as I was taking them out I notice that the squeeze out glue was still wet.
I put them back in the press.

Was the glue still wet due to being in a plastic bag?
Is the veneer bonded even though the ends are wet? I wouldn't think so.

Anyone had this problem?

The bottle also stated that the press pressure should be 100-150 PSI!!
That surely is a misprint.
My vacuum pump will generate up to 25 or so inches of mercury.
At 20", it is equivalent to about 10 PSI.
100 PSI is over 14,000 pounds per square foot!!

What seemed like a simple solution might turn out to be a bad decision!


TIA
