new to forum & looking for some advise.
I'm in the process of fitting a new shower tray.
The old one has been ripped out & whilst removing the tiles
the plasterboard came away with them.
I've fitted new plasterboard & now want to fit the shower tray.
The tray is going into the corner up against 2 new pieces of plasterboard
so I want to know if I can just use silicone sealant in between the tray
and plasterboard or if the plasterboard needs some kind of sealer (e.g. PVA) applied first.
