Do i need to tank behind Wet wall panels

[tile89]

Hi,
Before you all say wet wall panels are horrible and everything i agree, and would much rather tile a cubicle, but it is what the customer wants,
Just wondering if there is any need to tank behind them?

I always tank a shower area and sometimes round a bath before tiling depending on situation, but not really sure whether this is needed as there are no ways water can get behind panel and there is no grout lines for water to get through etc etc

Thanks

hi there the panels can still be penetrated if silicone seal is not sound or if not fitted into corners with silicone correctly
we have fitted them but have only fitted direct to moisture res plasterboard

if your tanking check out what adhesives for fixing the panels are suitable for direct contact with the tank kits through supplier is the only advice i can suggest mate

As a rule, no you don't have to tank first for wet wall panels..

i have never seen tanking used behind wet wall panels , so would agree with dave, but saying that it wont hurt if they can be fixed to tanking and i dont see why they cant imo , if the customer is ok with the extra charge
