Should I remove the paint from the wall before tiling?
Discussion
Hi,
I’m about to tile a section of wall above my bath in the bathroom in readiness for a new shower to be fitted. The house is about 9 years old and has a good quality paint on the wall. It’s not flaking anywhere and it seems to be the original paint as it’s a very good finish and I can’t see any other layers of paint underneath when I cut a hole in the plasterboard for the pipes.
So would I be ok to tile over the top of this paint? Use good quality shower tile adhesive and grout, or should I look at taking the paint off? Once the paint is off and I’m on plaster, should I then look to seal the plaster with something before tiling?
Thanks for any help. I want to make sure I do this properly!

If you tile onto the paint then the grip of the tiles is only as good as the adhesion of the paint to the plaster. I would be inclined to go over the paint with some sandpaper first to give a good key. Our shower was tiled years ago straight onot plasterboard with no special treament and no problems at all.

I'm pretty sure if you make up a a 50/50 PVA glue/water solution and roller it on this will bond any flaking paint & the new adhesive will stick to it nicely.
this is a bathroom. PVA should never be used as a primer in an area exposed to moisture. It goes soft when wet and your tiles will fall off.Most quality adhesives manufacturers wont recommended using PVA at all, anywhere.

What tile adhesive are you using? There will be instructions on the back or on their website on how to prepare surfaces, and particularly what type of primer to use. If you haven't chosen adhesive yet then don't by the crap from the sheds, get a proper trade adhesive. It is more expensive but worth it.Simpo Two said:

Yep; I used BAL. Seven years on and my 1/3 ton of travertine is still on the wall and not in the bath 
ks sake though don't buy it in Topps Tiles, it is a rip-off. Get it online.944fan said:

Cool.
Haven't bought adhesive or grout yet.
Been having a read and it looks like I should use an acrylic primer on the plaster. Then use a bagged adhesive as the tiles are quite large, 330x250mm. I was planning on buying BAL.
I want to make sure this is done right!!
I would always used bagged addy anyway but certainly with large format tiles.Haven't bought adhesive or grout yet.
