I'm using DAP Weldwood contact cement (the original flammable stuff that will make you dizzy) to glue some Formica laminate to pine (lining a storm window sill).
Here's what I'm doing:
I'm coating the wood and letting it dry 10 minutes. The wood proceeds to drink this up and leaves a dry slick surface as if I did nothing.
I add a 2nd and 3rd coat just like the first. I also now add a coat to the laminate. Now the wood looks sealed and after 5 minutes feels tacky. All seems well so I then proceed to stick the laminate to the wood.
After a day, it pops loose in several spots. I can re-press it and it'll stay for a second then comes loose again.
Any ideas on what could be wrong?
