Am trying to glue mount card to foam core with pva and a rolled then cutting 6mm spacers but when cut the spacers the card becomes unstuck from the foamcore. Any ideas?
Thanks, calico

Roller, not rolled. Sorry

If it's just for a spacer I'd use d/s tape. (Not ATG). PVA really needs to dry under pressure to form a good bond.

Your glue hasn't had time to go off.

I use pva glue, with ATG to hold it until it has gone off. D/S tape would work too

Cut the foamcore spacers first, and stick in the frame using a few bits of Double sided tape (to hold until the glue sets) and a few dabs of PVA . Then cut the card spacers and fit the same way to the foamcore spacers, do as two separate operations, don't try and combined them.

i tend to dry mount sheets together, then cut spacers from them

and for colours i dont use a lot i dry mount off cuts

i normally actually use just 2 lots of mountboard though, dont stock 3mm foamcore only 5mm

Pressure plus time fixed it in the end, but some interesting alternative approaches for me to try next time. Thanks all!
