My bedroom walls had a blue chalky covering on them (under the wallpaper) which I believe to be distemper. I assumed this as there was some similar chalky red stuff under the wllpaper in bedroom no. 1 which I scrubbed off over many days.
I wanted a quick fix for bedroom 2 so bought some Dulux Primer Sealer which is a solvent based and supposedly suitable for distemper and 'painted plaster'. (There are some patches of old emulsion paint on the wall, alongside and over the distemper).
I sanded the walls where they looked dodgy. I then applied the Primer Sealer and let dry for 2 days. I then painted over the sealer on one wall in Dulux white emulsion. I used a roller and big chunks of the wall started to flake off onto it. It had bubbled and flaked under the new emulsion in some areas and looked fine in others. I don't want this to happen to the other 3 walls so what do people suggest I do? Is there a quick remedy?
I have a feeling the right thing to do now would be to scrub/scrape off all the distemper back to original plaster (as I did in bedroom 1) and start again. If so, does anyone have any tips for REMOVING DISTEMPER THAT IS COATED IN SOLVENT BASED PRIMER SEALER? I want to avoid using any more solvent based stuff as it is making the whole household feel sick.
Thanking you in advance :)
