Miss Coat on walls - Tile Advice

[tilerbev]

hi

started tiling as a career a year or so ago now and have found this forum a lot of help very informative

i have a kitchen splash back to do in a couple of weeks. the customer had already put a miss coat on the walls before looking at the job as its a new extension they wasnt sure whether to tile or upstand the kitchen but now want to go ahead with tiling. now i know tiling onto a painted surface is not the one and am i right in thinking this rule still applys for a miss coat?

do i need to try and remove as much of this miss coat as possible and then prime the wall prior to tiling?

thanks in advance

Who is Miss Coat? Ha ha! You mean 'mist'.

You are correct, you need to remove this paint mechanically. Try using a really cheap flexible scraper (you can get 3 for a pound at the £ shop). I find that those bladed scrapers dig into the plaster.

On one occasion my customer was an artist and he had loads of sticky backed plastic. We put it on the wall and ripped it off a few mins later......it worked, but it was expensive plastic.

Then prime with SBR and tile.

Most mist coats can be washed off with a sponge and warm water which is much easier imo.

Try using a wallpaper stripper, be careful not to damage the plaster skim when scraping as if you do I believe this would be worse than tiling over the mist coat.
