Tiling on to painted wall

[Jamorgan90]

hi all,
I am doing on a job and just looking for abit of advice. I have a stair case wall to tile in 200x100 what prime would you use? Tile master grip ?

Maybe a little bit of overkill for that size of tile. Tape test and sugar soap is what I would do!

do I understand you want to tile on a painted wall? if so, remove the paint. couple of ways to do this.
1, sand downs with a sander, use a course grit... I've done this its fairly quick, but use dust extraction cos it can get messy.
2, spread a thin layer of tubbed tile adhesive on the area you want to tile, wait 15 minutes and scrape it off. when you do this you realise why you shouldn't tile over paint.
Then prime with a primer. I use tilemaster primeplus 3 to 1
hope this helps.

As @Chris Gibbs memrioned earlier.
Also if you can’t get all the paint off score the wall with a Stanley knife to give the walls key for the adhesive to bond.
Make sure you prime before Tiling

Clean paint, score, tile with White Star or equivalent.

Not advisable at all !

Also, I do not understand the advice of score paint with a Stanley knife to give a key, is that 1% of the wall where your scores are going to make a difference?

And if you
score plaster it weakens it. I thought we all knew this.

 

[Flintstone]

It's surprising how many of people tell me, it just needs a score up before tiling.

I remember a little while ago, flying into Geneva for the day just a little job. After being told the wall was new plaster board. Got there and a painted wall, was told by the site agent he has sealed it and it will never come of the paint. I said may be not. But what has that got to do with how strong the Paint is. Good bye I dont want to miss my plane in the morning.
