I'd like to fill a gap between the bottom of my tiles and the bottom of my shower pan. The shower pan is fiberglass.
I'm considering using an epoxy to fill this void, and I want to put tiles on top, flush with existing tiles, to make it look nice.
Will (cement-based) tile grout adhere to a set epoxy such as Marine Grade Epoxy Adhesive Paste?
An alternative is to use the epoxy to bind a piece of concrete board, and then grout the tiles to that.
Suggestions / implications?
