First of all a big hello to everyone here.
A recent weekend project to repaper the stairway of our 1920's ex council house is becoming somewhat more of a job than anticipated. Having steamed of the old paper (a total of 5 layers), the ceiling paint lifted away in an almost unbroken sheet across the entire ceiling. The surface below... well i am assuming it was once paint, but was now a fine powder akin to talc.
Obviously, nothing was going to stick to this, so after a day of wetting down the powder and scrapping it off i am back to what appears to be bare plaster - though it needs a final wipe down as a quick wipe still shows a very fine layer of dust on surface.
i have a can of dulux crack free ceiling paint ready to apply. However before painting would it be best to seal the bare plaster. I am told a dilute PVA is a big no-no, would a 50/50 mix of the ceiling paint and water be suitable to seal/prime the surface before applying the final coat(s)? or is there a product anyone can recomend that would do the job? it is not a large area all in all, but its location and working from a scaffold board between two ladders to reach means i am keen to only have to do this the once.
