Painted Conservatory flooring - please help

[mbga9pgf]

hi all, having an absolute nightmare with a 25m area to be slate tiled (flexible cement based adhesive).

i was wondering rather than grinding off the paint, which is taking ages and trashing the house, i could pour a thin coat of self levelling screed to the concrete to provide a good key for the adhesive?

i hired a power stripper from brandons and after about 5m2 and all i have succeeded in doing is destroy the grinding head on the tool. the paint has come off in patches but where it wasnt trowelled off, its refusing to budge! not to mention a very unhappy wife with the generated dust (despite putting up dust sheets its got everywhere)any other sugtestions like a re-screed.

The only other option I can think of ould be to key up the surface rather than completely remove it with a sanding disk (get the gloss off the paint) then SBR slurry coat it as a primer. Would this work or would I be asking for trouble?

dont use self leveller. if the paint is very secure get some acrylic bonding agent (we sell granfix) and mix it roughly 1:1 with dry cement based tile adhesive to make a slurry mix. coat the floor in this and let it dry, then follow with a cement based tile adhesive - the 1 part flexible adhesives will perform better than a standard adhesive so go with one of those.

you have to remember you are sticking to the paint, so if thats loose you tiles will lift. if its solid it will be fine.

not sure if you have bought your slate, but if not we could supply this and the adhesives\bonding etc you would require
