Sealing Around A Shower Tray

Ensuring there are no leaks from a shower cubicle is vitally important as any water egress can cause damage to the property in the long term.

The first step to elliminate leaks is to ensure that the shower tray is installed solidly. The tray then needs to be sealed to the existing wall with a good quality silicone sealant (we recommend Dow Corning). Smear the silicone up the wall slightly so that there is a skirt of silicone running around the tray.

The panels should then be run down over this seal and another seal applied where the panels meet the tray.

Silicone usually turns mouldy from the back and grows through the seal to appear on the front. For this to occur there must be permanent moisture behind the silicone which can occur due to faulty grouting or movement of the shower tray breaking seals. The surfaces needs to be bone dry and free from dust, soap residue etc before application of the silicone sealant which, together with a solidly installed tray, will ensure it does not peel away.
