Un-intended crackle glaze...

IM

Morning all.

We're in the process of decorating our daughter's bedroom at the moment (a basic "slap some paint up, we're looking to move in the New Year" job...).

Unfortunately, where we have emulsioned the walls (old textured wallpaper with numerous previous coats of paint) we have got what looks like that crackle glaze effect that was all the rage for doing on old furniture on 90s DIY shows.

I'm guessing that there has been some sort of reaction between the old and new paint (the room isn't particularly cold or warm).

I don't want to have to go to the faff of stripping the wallpaper (and risk taking the plaster down with it...), so any suggestions???

i don't think there is anything you can do apart from stripping off paper
you can't sand down or fill the wallpaper
try and see if you can strip off a small bit and see what walls are like underneath , you will need a steamer to get it off

Maybe you could 'seal' the old emulsion before painting? Have you put the paint on very thickly as this can sometimes cause it to crack?

The problem with previously painted wall paper is that you cant sand it down like you can with ordinary walls.
And if the existing paint was silk, and you have put on matt, and of course you cant sand it down to get a key, then you will get crazing, or if you applied the paint too thick, (straight from the can)

You could perhaps go over it again, with a thinned down coat of emulsion, and if its still crazes, then you have no alternative but to strip it off.
