Hi All,
Just a quick question,Im tiling a bathroom and tiling over existing tiles.
Which adhesive you you recommend.
Will be grateful of the help.

What tiles u using and what size mate?

the tiles are 250mm by 200mm Ceramic

Tiling over tile isn't really a brilliant option, always remove the old if you are able.

Main thing to bare in mind is the combined weight of both sets of tiles, adhesive and grout all hanging off a substrat you cannot see to check if it's in good enough condition to withstand the strain.

If you are still happy with doing this, then I'd advise a rapid set cement based adhesive only.

thanks for the advice

Didn't say there was anything wrong with tubbed addy, just I would advise and use myself cement based, that's all

If you are tiling over tile, I'd recommend giving them a real good sgub with sugar-soap and get all the grime off (even the stuff you can't see) and then allow them to try a bit before starting.

I'd follow Fek's advice regarding attempting to take them off, and if you can't do that, at least ensure the substrate will carry the weight. You wouldn't want them to fall off on you in the future they can be sharp and heavy.

defo a cement based adhesive and a flexible one at that,although white star says it's fine i wouldn't bother to much slippage etc,and to be honest i would also prefer the bathroom stripped back or a disclaimer signed

An advantage to cement-based would be the fact it doesn't need air to set/cure. So you know when the bag says the adhesive is set, it will be. Though with tubbed, if you're tiling on ceramic or porcelain with ceramic or porcelain, your drying times alter quite a bit, obviously.

Cement based adhesive for me also

I have used tubbed on tile over tile, just they don't dry as quick as I'd like.

Didn't we cover this a few weeks back and apparently even with a disclaimer it would still be the fault of the tiler if it went wrong and he knew there was a chance it could go wrong.... and signing a disclaimer proves the tiler knew which would go against him.

Or was that something similar?

If the tiles are gloss finish, then you cannot use tubbed or standard flexible cement based adhesive...It will need to be an S2 standard..

Thanks at lot guys you have been really helpful.

Sorry Fek wasn't digging. Just wondered why you said cement based only.

I have used tubbed gear loads when going tile on tile with small ceramics coz i find the grip alot better.

I've used Gold star alot too but they changed the name of that.

Never used a Mapei powder on the walls yet as i stick to another brand, but what do they recomend as the best powder for walls, tiled and untiled?

I didn't actually mean to say cement addy only as I have used tubbed before, and I didn't take it as you we're avin a dig either

Didn't Bal re-brand that as something like Natural Stone addy, though ****** ****** still have Gold Star to order on their website
