Crazing paint after painting over silk paint in front room

Postby emmajackt » Tue Feb 16, 2021 8:58 pm

HI, When I moved house a few years ago the front room walls were painted with a silk paint. I mist coated over this and then I painted my walls with some Johnsons matt emulsion but as I was rolling it, it was bubbling and causing all sorts of problems. I am now going to rub down and tackle the job again. Looking at the walls apart from the peeling, it has crazing all over as in the attached picture. I have been advised to use a solvent based undercoat and then emulsion over that. I cannot find a solvent based undercoat/primer paint for walls anywhere and was wondering if the solvent based paint for wood would be ok? It seems to me that it would be too thick, even if diluted with white spirit, but if someone could point me in the right direction, I would be most grateful

Cheers, Kev.

Hi emmajackt
Oil based wood undercoat will be fine - thinning will depend on the make you buy. Doubt you will ever get a smooth finish short of getting a skim coat applied.
