Tiling a wet wall
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? http://www.screwfix.com/search.do;js...chbutton.y= 0 (screwfix 97710, Dunlop Fix 'n' Grout Waterproof Adhesive cheers, NT |

(screwfix 97710, Dunlop Fix 'n' Grout Waterproof Adhesive cheers, NT 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. Simon. |

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. -- Andrew Gabriel [email address is not usable -- followup in the newsgroup] |

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 |

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! NT |

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. 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. -- Andrew Gabriel [email address is not usable -- followup in the newsgroup] |
