Boarder line onto perfect plaster with no paint. Who can tell how well the plaster was fix ?
Don't risk it. Do it once and do it right. 😉

thank you, should I look in to some tile backer boards? Can these be fixed to my plaster walls..or does all the plaster need to come off first?

i've already noticed 6mm and 12mm thick boards…is 6mm ok for walls? i saw this stuff… http://www.tilegiant.co.uk/pdf/nmp/nmp_guide.pdf

and this 6mm Jackoboard backing board for tile | Jackoboard tile insulation board

(sorry, I'm a useless girl, so learning as I go! 😉 )

Plaster should come off first unles you can screw through to a substantial surface behind.

Without screws, you're relying on the plaster to hold the weight of the board, the tiles and 2 layers of adhesive.

So now we need to know, whats behind the plaster?

thanks, i believe it is either brieze block or brick - all solid walls i.e. not stud walls. the flat was built in 1953 so it's pretty solid construction.
