:o thank you all for your wonderful help - I shall be using watered down emulsion to seal/prime the walls as suggested. Problem solved at last - many thanks
no, I am going to be painting the walls but am having to take them back to plaster due to old peeling paint. Just not sure exactly what "size" is other than you paint it on your wall before putting emulsion on (at least that is what my dad has suggested!)
HELP!! I have stripped off wallpaper in my daughter's bedroom only to find ancient paint bubbling underneath. I am in the process of stripping this back to plaster as it was painted directly onto the plaster originally. The house was built in the 30's and I believe the plaster is quite old...
