Hi,
I'm going to tile a bathroom, putting the tiles on bare plasterboard.
When a product says use on gypsum, do they mean the plasterboard or the plaster (which often has gypsum written on it) or is it the same thing?
I'm using Mapei Mapegum around the shower, but it says use Primer G first if the surface is gypsum based.
Sorry to sound dull!
