Horrendous nightmare with paint...

Postby dns » Sun Sep 12, 2010 4:32 pm

I started re-fitting my kitchen a while back.

Chose Dulux Rich Matt for the walls, which were generally in good condition. In places I filled the odd hole with plaster (dents, screw holes, cut-out left by old socket)

It seemed to cover fairly well initially, but then started to bubble badly when it dried, especially when I did a second coat.

I waited for the paint to dry, then tried to sand and scraped the bubbles off, but the paint started peeling away in huge strips, like wallpaper. After much elbow grease, I peeled away as much as was coming off freely, smoothed with surface with Ronseal Perfect Finish (suitable for painting without treatment) and left to dry.

The nightmare came again when I started to re-paint. Previously perfect sections started to bubble...

I'm now stuck in a never-ending cycle, I rub down a bit of wall, think all the problem paint has gone, wash the surface with sugar soap solution prior to repainting, only to find that this causes even more paint to peel...

Anyone got any tips? At the moment I'm seriously considering cutting the problem section out of the wall and starting again with new plasterboard.

Good couple of coats of uni-bond should seal it ready for painting. If its an old house? You might be trying to paint over some old distemper.

Is ronseal not for wood? Sorry i only but stuff from dulux.

That is a water based eggshell kind of paint mate need to use a proper primer or a matt the same colour for a base coat.

don't use unibond it will not take a paint. use a watered down emulsion first as a sealer. also try cleaning the walls - use sugar soap, being a kitchen the walls could be coated in a layer of grease from all the cooking. then seal.
