Hi,

Im painting my hallway and have an issue with the paint scaling as seen in the photo. I have removed old wallpaper an am painting on top of very old yellow paint. The scaling appeared on the second coat of paint last night. I painted the first coat with standard dulux matt and used dulux trade matt vinyl paint for the second coat. What causes this and how can i fix it? Should i have used some kind of primer???

Thanks

Marc

The emulsion has re-activated the wallpaper paste residue on the wall. When you strip wallpaper and want to paint the walls you should remove all traces of old paste to stop this happening. But all is not lost, get a tin of Zinsser Gardz, give the walls a sand down, dust off and apply a coat of Gardz, allow a couple of hours to fully dry and then you're good to go with your emulsion.

Thanks Ian,

I wondered if this might be the case but how come the first coat i applied didn't start cracking, its only really appeared in the second coat?

Also instead of zinser would polycell 3 in one 1 base coat work? I have a massive upstairs and downstairs hallway to repaint so need about 8 litres!

Cheers

Marc

I'd stick with the Zinsser gardz if I was you, it is designed for this sort of problem and won't fail you. Probably the second coat re-activated the paste because the more water soluble products applied, the more chance this will happen. The picture is a classic example of paste re-activating with emulsion.

Just to add, the Zinsser gardz goes a long, long way. It's thin almost like water so 5 litres would be enough I should think and it's not that expensive if you shop around.
