I'm just about to install a quadrant shower tray directly onto the floor(access to trap available in cupboard directly below) which will be bonded to the WBP using mortar but wondered if I needed to prime/seal the WBP ply before laying the mortar or will the mortar bond to the ply ok?
Secondly, the shower trap has a large rubber seal that fits on the underside of the shower tray. Is it recommended to double seal with silicone sealant or will the rubber seal be good eneough?
