Hi All,
I have just joined the community so I hope I have opened this thread in the right forum area.
I have done a lot of research on this topic but I still have questions that I can't seem to get an answer to.
My plan was to fit moisture resistant plaster board in the shower cubicle, apply tiling primer,followed by tanking paint. I would then tile onto the tanked areas and grout the tiles.
I am planning to use a shower tray with tiling upstands with the tiles lipping over the upstands and sealed to the tray intself with silicone sealant.
I have however just realised that there seems to be a problem with this.
The reason I am proposing to use tanking is because tile grout and tile adhesive do not form a 100% water barrier. The tanking therefore would give this 100% water barrier instead.
My problem is as follows: If the water does penetrate through the grout onto the tanking interface it would then have no choice but to seep down the tanked wall behind the tiles. When this moisure gets to the bottom where the shower tray is located it would seep into the shower tray (assuming that I have rebated the upstands into the wall slightly). The problem is however that the water cannot drain away from this point because the shower tray is silicone sealed to the tiles. The water would then effectively be trapped between the tanked wall and the silicone sealant.
Have I missed something because I can't see a solution to this.
Any and all help would be much appreciated.
