I would like to use latex paint to on old plaster walls in a 1800's house. Some of the walls had to be patched with new plaster where the old plaster was removed down to the lathe. There appears they have been coated with calcimine before being wallpapered. I searched the internet on which primer to use before latex and now I'm totally confused. Should I use oil, water based, shellac or Zinsser Guardz? In addition several of the UK sites mention that the old lime walls have to breathe . What happens to the walls if they can't breathe?



Also does anyone know of any makers (US) of latex free paint?

Futoyos(sp) would have a better idea about Gardz, but I've had to do repairs on old plaster before. Before patching I would prime with gripper, patch, then prime again with gripper (better safe than sorry), then paint with my acrylic top coat

From what I recall in painting some older stucco homes with the old limewash coating, we would have to wash it off first for proper adherence. Then, Im certain any multipurpose sealer would do a good job prior to painting with a latex.
Latex free paint? Like 100% Acrylic?

farm1684, welcome to Paint Talk. I couldn't find your introduction to this forum. What is your paint related trade or field, if I may ask?

Intro

I'm just an amateur DIY painter helping family fixing up their old farmhouse. It's more of a hobby then profession.


By the way thanks to all the replies.
