Hi


Need to tile a wall thats always wet. Yes, drying it would be ideal,
no, its not practical.

I've got some of this, would it do the job?

Dunno what the dunlop one is, but I wouild have though you'd want a
cement-based
adhesive (not pre-mixed) that will set on a wet surface. And a good
key on the surface - dig out some mortar between bricks etc.

What's the wall surface (I presume not gypsum plaster)?

Is there pressure behind the moisture (e.g. a celler below the
water table), or just penetrating damp with no significant
pressure behind it?

I'm guessing you might do better with just a strong sand and cement
mix, depending on the wall surface. That won't mind being wet, but
I suspect most of the bonding agents in tile adhesives (the glue)
won't work at all if kept wet, and is likely to make the adhesive
weaker than it would have been without the bonding, which basically
leaves you with just [fine] sand and cement. Could add a combined
waterproofer/plasticiser too.

If there is pressure behind the moisture, then you may have to tank
the wall first, or it will ultimately push the tiles off, and I
doubt you'll manage to get the tiles act as tanking for any length
of time.

Tile adhesive is water based so won't object to a bit extra surface
moisture providing, as you say, it's not coming from within the surface
you're tiling

The water is meeting the tiles from behind, but at a slow enough rate
that I dont think it would push them off - there is an area at the
bottom it can escape. I think Andrews right about going with sand &
cement, I dont really feel like chancing it with the dunlop stuff.
I'll check more thoroughly when I do it but I'm pretty sure the wall
surface is good and sound, so it cant really be gypsum. The wall is
porous enough for the bottom drainage to handle the water ok.

Thanks everyone, can get on with it now!

Tiling this wall will reduce the opportunities for water to escape and
quite possibly build up pressure that will dislodge the tiles over time.

I think you should deal properly with the water before even thinking
about tiling the wall. But then I would, wouldn't I?

Getting the sand and cement to stick to the wall might be a
challenge. Normally, one would wash over the wall with dilute
PVA, but that's going to be a disaster here. I might be inclined
to brush over with a thinned cement wash, a few minutes
before applying the sand and cement. That's a good way to get
sand and cement to stick to surfaces which it otherwise might
not, as long as it doesn't leave the wall too wet.

Note that the sand and cement will take much longer to set
than a normal tile adhesive with bonding in it, and when it
isn't quite set, I suspect tiles will easily pull away. I
wouldn't dream of touching it (e.g. for grouting) for at
least a week, or two or more weeks if you can. It takes about
6 weeks to reach full strength, although you can probably get
away without waiting that long if you're very careful.

Depending on what the tile backs are like, the same cement
wash trick might be useful on them.

I haven't tried this myself -- just extraplorating from one or
two vaguely similar things I've done in the past.

Many years ago, I had to tile a wall in a steam room. Other people had tried various tiling
adhesives, and they all failed.

I stripped off all the old tiles, pva'd the wall and used swimming pool tile adhesive (cement based)
and swimming pool grout.

It did the job.

But in a steam room the moisture is on the tile side, not coming from
behind them. In the latter case I don't think one stands a chance in
hell of getting tiles to stick

I agree.
