Hello all my buddies,
i have a site meeting in the morning on my hotel job,i'm for starting it on monday.
The builder told me on the phone today that the hotel owner wants the showers all tanked and the floors !!! yes the FLOORS !! anyone ever done that before or is he up the river without a paddle??????

Believe it or not, water falls to the floor when you shower

I could hold a long lecture on the merits of waterproofing, but I won't, as I'm a bit short for time atm. I'll say this though:

The floor and about 1 metre up on the walls, in a 1 metre radious from the shower fitting, are the most important surfaces to waterproof properly, as those are the areas which aree going to be exposed the most to water. Pay particular attention to a proper seal around the drain. I assume the floors are concrete, but know that concrete isn't (normally) a waterproof material. Damp concrete can weaken, and be attacked by mold. Damp can also infiltrate more sensitive areas through concrete. Need to go. Back later.

One customer got me to tank her shower room floor, the tile shop recommended it. Was happy to oblige.

Bisazza do a thin blade for the 4" angle grinder for glass mosaic, it is supposed not to chip them.

It really depends on the type of glass, and the size and thickness of the glass tiles. If your normal manual tile cutter doesn't explode them, just make sure to sand the edges a bit, as they tend to be nasty. Otherwise, I'd recommend a wet saw with a blade meant for glass.

Make sure to use white adhesive which is specifically meant for glass and other very dense materials. Gray adhesive can shine through in a less than pretty manner.

Thanks Dave,
these glass tiles aren't mosaics though, modular laid to a pattern,
In Co.Down.
I'll try to tile the glass wall first then cut the porcelain walls into it which will hide the edge cuts for me.

i found that the bigger glass tiles from original style cut easy on a rubi. its the one and two inch mosaics that shatter

Hi Joe

Tanking floors is becomine more popular wiyh the majority of leaks originating from the wall to floor transition. We have just sold a 15 room spanish hotel with showers and all floors done.

Our waterproof membrane the Durabase WP will suit your needs I would think and you are assured a good deal being a forum member. Could get it on site bit sharpish for you !!

If you would like some help, a costing or you want to pass our details on to your specifier then email or call us on the below.

cheers

Thanks wetdec,

i think i'll be recommending a big order for Mapei keraflex white.
