I’ve made a number of hydrocal castings of a cut stone wall. They are thin, and a bit fragile, and I need to glue them to a sheet of styrene for support. I’m gluing the relatively-smooth flat back side to the styrene.
I tried hot glue, but that didn’t stick well to the hydrocal, and it also peeled off the styrene pretty easily. I tried Liquid Nails for Projects, which kind-of worked when I put a lot on, but I’m suspicious that it might not last.
Any other ideas?
Might want to try some epoxy, you can look for the type that bonds to plastic but any kind should work on the castings.
use the two part liquid not the thick clay type you blend with your fingers.
if you were using cardstock or thin wood for a backing i’d try typical wood glue. cheaper if you have alot of surface area. bonds well with plaster so i assume it does ok with hydrocal
good luck, bobt
Use white glue and attach your castings to aircraft plywood (available at just about any hobby/craft shop in a variety of thickinesses) I use aircraft plywood as a base for stuco structures, good stuff.
Try ceramic tile adhesive. Works for plaster to wood, plaster to plaster, foam to foam and foam to wood.

I bet the clear goop that you use to seal the joints in built-in vacuum pipes (ABS) will rate an A+. Fumes help to pass the time, too.[:D]
Clear silicon caulking is good for this, as is any type of Goop, which is also just clear silicon.
