Tiling on painted plasterboard walls

kevin0410

I have painted plaster board walls in my bathroom. Can stick tiles straight on to this? Would it be advisable to give the walls a blast with the sander to rough them up a little?
Many thanks

Youn can not tile on paint

Walls will have to be sanded and scraped to remove paint

Once removed prime with Primer G from Mapei

Do not use PVA

Yes - it would be advisable to give a sand first. Once done you should not need to put any "Mapei" products or anything on there if you tile well!!

Maybe the Mapei salesman will disagree - whatever - check out tilersforums.com for all advice and help on tiling. Great guys and you will get good, sound, quick advice.

The plasterboard will have been plastered,A acrylic primer is required,Dilute to stop it forming a skin that peels
