Gluing Pink Foam to Plywood - Model Railroader Magazine

Want to try an unbelievable adhesive? It's cheap, easy to use, cleans up with water, holds foam to foam, foam to wood, plaster castings to wood or foam or plaster to plaster. It will hold as good as liquid nail and stronger and more flexable than carpenter's glue.

Try ceramic tile adhesive. My son experimented w/ it for a school project- I wasn't home yet and he needed to glue foam to plywood then add layers of foam on the base foam. Kind of sounds familiar doesn't it. I saw it and thought it wouldn't hold very well. This stuff worked better than anything else I have previously had used. Since then I'll use it anytime I need to laminate foam on wood or place those hydrocal castings and small pieces glued between. For large areas, I use a notched trowel this allows for a good initial tack and the trapped air aids in drying. Glued areas weighted overnight are totally unseperable. For small spots, Cast portals, rocks walls, I use a small putty knife or a strip of wood shingle cut as a spatula just for the job being done. You can but the mastic in large buckets or in qt containers. Liquid nails in a caulking tube is easy to dispense and I still use it. But give the tile adhesive a try. It may only be an additional glue for a special use or you could use it as I do. I feel if it will hold ceramic tiles in a shower wall for close to 30 years there must be something good about it.
