Re: titebond frp vs pl premium
Type: Proprietary emulsion polymer
"Do not use over treated plywood or metal, plastic, foam board, painted surfaces, sealed concrete, certain types of specially treated or moisture resistant gypsum wallboard, or other non-porous surface"
PL Premium is a polyurethane adhesive
thats the info. im sure you can, but I believe the reason PL Prem is used is because it is a polyurethane adhesive, that holds up better to moister than an emulsion polymer.
maybe someone can elaborate or correct me...
