some stains from setting as quickly as they might otherwise, possibly allowing a little time to clean them up. But in a shower, unless you're drinking a lot of red wine without the shower running, I don't see much gain from the sealers in that application.

If you'll type marble shower into the Advanced Search feature, you'll find a good bit of reading available about the potential issues I was referring to.

Salvageable? I dunno. It really depends upon how much glue there is on those tiles. If the backs are pretty well covered and it's a water soluble glue, I don't see a lot of hope unless you're willing to remove and clean all the pieces and set them individually as Al is suggesting. That would give you bragging rights and you could say you set them the way tiles were set back in the good ol' days. Except I'd recommend you use thinset mortar instead of Pure.

Aside from that, a different tile selection is all I could recommend. Or you could simply set what you have the way you were and see if it stays in place. I've certainly been wrong before. Probably won't matter what mortar you set it with, but I'd recommend a modified thinset mortar (ANSI A118.4) anyway.

We (TYW) once asked a major mortar manufacturer what thinset mortar they would recommend for setting that kind of mesh mounted tile on shower floors and the response was, "Somebody else's." True story.

My opinion; worth price charged.

You understand, C, that penetrating sealers do not really prevent stains on tiles?

As they guys have said, Unibond Anti-mould Shower & Bathroom Grout and Adhesive is not propper stuff to use really, get some propper Mosaic fix adhesive, and a good mocroban grout which is anti mould.

Not to ask a really stupid question but, there isn't still a plastic type of backing on the mosaic tiles is there ? like a sheet film, as this has to be removed "if there in the first place" before fixing.

I know it's a dumb question, but with you saying the mosaic tiles just are not sticking, even using poor quality ready mixed duel adhesive\grout, I would of expected mosaics still to grip, or you simply might not be pressing firmly enough onto the mosaic sheet enough when setting them.

Good luck
