Awkward wetroom floor.

[JMC tiling]

Gave them a ring this morning, company called mosaic del sur, and they assured me that they are suitable for wetroom installations. However, they also told me not to pre-seal the tiles as it can cause a problem with leaving salt marks on the surface if not fixed, anyone heard of this? They also said that the customer has to expect the tiles to change in nature and appearance over time when water and soaps etc to penetrate the tile especially in hard water areas although this helps with sealing the tiles up. I've decided to install but have made the customer aware of all the potential issues.

Not much more you can do apart from getting it in writing and asking the customer to sign your copy!
Some leave the sealing till the end because of efflorescence and I seal as I take them out the box!
The tiles will discolour over time but that could be weeks not months/ years as may be suggested and as for that helping to seal the tiles - I'am at a loss to see how strawberry shampoo will help with a patina build up!

The guy I spoke to had a rather interesting french accent but I think what he was getting at was that dirt and grime over time will naturally seal the tiles and make them less porous as they would have done 100 years ago before any sealers where thought of. Can't see how that will help the customer in a few months when they can't clean them up. I'm getting everything in writing as you say as personally there is no way I would ever recommend these tiles on a wetroom floor. Problem is, when I told the customer yesterday that they might not be suitable, she was nearly in tears but they really should of consulted me before buying and designing the bathroom.

These tiles are so so porous and prone to staining, it's gonna look a mess within a few months I'm certain of it! Water will get past the surface and into the cement back and that's like the most absorbing material you can imagine

I completely agree

Finally got round to this one, logistically was testing but worked out nice. I also undertook the plumbing which makes these jobs that bit more interesting.
