: : Looking for a good adhesive promoter. I've been trying PVA with little success. Maybe I'm not useing enough coats?

: Hi Jim
: What materials are you trying to bond?
: Regards gordon

Silica Bronze arc sprayed onto break-away plaster molds. I've had to go with a fine texture on the smooth plaster surfaces, but I would like too just paint a adhesion promoter to speed up production.

PVA doesn't seem to help, but it does make the plaster really hard to clean off. Zinc sticks on the smooth parts, but I want the bronze surface without having to re-spray after demolding.
