Dear Forum
ive just joined up to ask for some advice.
I'm refitting and modernising our under stairs toilet. New units, new everything.
The room (1.5x1m squared floor area) has had wallpaper stripped, walls washed, sugar soaped, all very clean. top half has been painted as bottom half to have tiles coming one tile above the little corner sink. Tiles are ceramic 450x250x9mm.
Under the old removed wallpaper was a coat of paint, probably painted in 80s. Seems quite tough so did a gaffer tape test and only a little came off. To be safe I've scored the walls quite a lot, score marks about an inch apart and criss cross over the whole tile area.
This exposed a bit of plaster in the score marks etc. So to seal the wall and prime the exposed plaster I used some SBR I had. My concern is I may have used the wrong thing. I had some Cementone SBR Admixture. Only afterwards did I wonder if this has different properties to a normal SBR Primer. I had mixed it 1 part water 1 part SBR. It's all dried now and feels a tiny bit tacky.
question is, was it ok to use this? I scored the wall again in one area and was able to just raise a little of the dried SBR skin off the wall. Only a very very little. But is this enough to mean the tile adhesive won't be any stronger than the SBR's bond? Adhesive I've been sold is 'norcros one part flexible white adhesive'. Is the skin element of the SBR on my wall normal SBR behaviour or is the fact this is an admixture mean it's not the same as a SBR primer?
Have I made a boo boo?
thanks for any feedback, greatly appreciated.
