Split Face Stone Mosaics in a Shower. Advice Please

[jlktiling]

Hi guys.

I have a customer who wants to use split face travertine mosaics in a shower. (see attached photo)



Obviously they are very pourous, so what background should i use?

Tanking system, or kerdi.

And what is the best way of sealing these, as there is such a large area. (is there a sealant that can be sprayed?)

Its not a wet room, so there will be a tray.

Thanks in advance for your help.

Would'nt put those in a wet area to be honest.

I agree with andy all because there are lots of gaps in them sort of tiles for mould but you can seal them there are the spray one's but i dont recomend them coz they might leave tiny gaps best one is one in a tub and you paint it on so you know you have a 100% coverage you can get it in topps tiles under tile protection hope this helps

Why not Andy?

They can't be grouted, so that's the main reason for not having them in a wet environment. Too much water would be getting in behind the tiles and into the mosaic mesh, eventually the mesh glue will soften and tiles will come loose, you will be relying on the adhesive to keep it all together.

check with the supplier, you may find there only recomended for a feature wall in a non wet area...

You can't grout those in, they are designed for feature walls.

about three months time these mosaics turn in to a "mold nest" in wet area
