i am tiling a walk in shower 1450 x 850, on new skimmed ordinary p/bd.i went to topps to ask for a tanking kit and they recommended homelux matting. i can get two runs horizontally across the two walls where water splashes and the third wall where i walk in ,just tile the wall w/o matting.
is this practical or do you recommend a different method. also the guy in topps said overlap the matting by 5mm and don,t bother with joint tape. this does not sound like good advice as i would have a lump to tile over.
also what adhesive should i use for the matting.
thanks in advance
ps there is a shower/fan light in the shower

The membrane needs to over lapped by 50mm not 5mm as recommmended...

what size tiles are you using and what type please...then we can advise more.?

Just to expand on Dave comment - The homelux membrane should be butt jointed and overlapped by 100mm wide jointing tape ( ie 50mm each side overlap). If your going to the expense of tanking do the job as they request or you will have no come back when it leaks!

John.

John is right...but once you get used to a system then the tapes do not have to used as you can simlply cut strips from the membrane or over lap by 50mm each side but for new comers then defo use the tapes...

the tiles are ceramic (rocersa atlantis) and they are 400 x 250 with a 50 x 250 border tile where they meet

I find the Homelux mats quite thick. Wetdecs supplies stuff that is thinner (Durabase WP) and gives less problems for lippage IMO.

If you are using a waterproof matting you really need to be using a powdered adhesive. White star is dispersion and as such dries by evaporation of moisture. If you don't give it anywhere to dry through, the adhesive won't set!

ok grumpy grouter the white star is going back and the paddle mixer is coming out for another workout
many thanks terry

ps i was advised that with tiles under 300mm wide the white star would be ok but i joined on here to get advice from experienced guys not salesmen so ta again
