Tiling onto eggshell paint

[Ambergreen45]

Hi,

Originally posted on Decorating and Painting without realising there was a Tiling section

I want to tile on both sides of a corner in the kitchen behind the top of my freestanding cooker. The area is 1 square meter.

The main area have a thick coat of eggshell paint which I know would not absorb any moisture from the adhesive. Is the setting process done by hydraulic action, once water is added to a dry powder adhesive? Would that be better in my case than a pre-mixed version?

The other part of that area is very porous because I had to re-plaster that section. Perhaps to prevent too much moisture absorption from the adhesive would I need to seal that section with SBR or prime it with 50% paint 50% water?

Should a normal adhesive be sufficient to tile around the top of the cooker or would it have to be a heat resistant adhesive?

Thanks for you advice.

Best to remove paint as any tile stuck to it will be stuck to the paint not the wall.

Cement based adhesive dries by chemical reaction. Tubed relies on exposure to air which is why there's a tile size limit. If they're small tiles then tubed should be okay but bagged is usually better at sticking things and cheaper.

If the background is very absorbent then priming will never hurt.

Tiles shouldn't get hot enough to need heat resistant adhesive. Are the tiles heat resistant?

I've tried rubbing it down with medium size sand paper, the paint is so though it could take days... Any idea on how to remove it reasonably quickly?

I’ve heard PVA is no good. Could I prime the new absorbent plaster with SBR or a mixture of 50% paint/50% water?

They are ordinary 100mm x 100mm tiles, so I presume these should be ok directly around the top of a cooker.

Thanks.

If the plaster's very new then you need to leave it to completely dry or your tiles will drop off. Don't use PVA or paint, use a specialist tiling primer or SBR.

I may now have to tile over 2.5 square meters. Any ideas on how to remove eggshell paint from the wall as sanding down would take far too long as the paint is really tough?

Thanks

It's probably true tiles should be sticking to the plaster, not to the paint. I'm trying to find a way to remove tough thick waterproof eggshell paint from the wall and it could take forever just rubbing it down with sand paper, as hardly anything comes off. I've managed to remove the odd flaky bit with a scapper, but the rest won't really come off. If it has to be done, does anyone has a more practical way in how to remove it?

Many thanks.

as long as the paint is not flaking off prime with sbr then tile it, the tiles are 100 x 100 not 600x600

I've got some SBR left from last year but it doesn't say much on the instructions. Would you say I need to dilute it with water and if so at what rate?

Thanks.
