Having used some sculptamold I would say you want it fully cured.
I used inexpensive laytex caulk for foam to wood, cork to foam, foam to foam, plaster to foam and track to foam. I was pleased with all the results.
Good luck,
Richard
I would say yes to both.

I've used Sculptamold to fine tune a roadbed base going up a grade. The road will be cut from 2mm black foam. My plan is to attach the foam road to the road bed with a thin layer of clear acrylic caulk. (I want a firm semi-permanent bond but also something that could be removed if ever needed.)
1. Does sculptamold need to be 100% fully cured before bonding a roadbed with acrylic (water based) caulk?
2. Is acrylic caulk the best choice for a semi permanent bond? (DAP Alex Plus clear).
