PSA veneer buckling problem -- need advice

Don’t know what to tell you.
I have use a fair amount of PSA veneer. I use it for the exposed end panel in kitchen cabinets matching the wood of the face frames. Never had a problem with it. Did you follow the instructions for applying the veneer? Was the surface of the door sealed? PSA is not supposed to go over raw wood.

How did you apply pressure to the veneer? Hopefully not with a roller like you would do with HLP (Formica)

Chances are that you didn’t apply enough pressure when you applied it. it’s called pressure sensitive adhesive for a reason. You should use a veneer hammer or veneer scraper to apply the pressure and make at least 2 passes over the entire surface. Failing to seal the substrate or moisture can also cause problems.

Toward the bottom of the page shows a veneer scraper and a pattern of applying pressure.

Yes, I sealed the door prior to applying the PSA veneer, and I used a veneer scraper to apply pressure. It all looked great for a week or two..

Back to square one, don’t know what to tell you. They claim you can use any finish on it.

Any idea how old the veneer was? Just wondering if the adhesive went bad or perhaps was exposed to extreme heat somewhere along the way. I did a quick search and found one reference to a 2-year shelf life which doesn’t seem very long to me. Temperature and humidity can also play a role, especially at the time of application.

Just thinking out loud.
