How do I stop the foam sticking to the plywood? And, how long does it
take before full expansion is reached?
Polyethylene film. Bin liner, whatever. Peels off the foam a treat.
Yes.
Cling film was suggested as well.
On realising how long the cure/full expansion time is I decided to fall
back to the *trim off the surplus* method.

Tim, for trimming when hardened, a 12" hacksaw blade with a handle made from
gaffa tape wrapped round one end works well.
