Paint is going wrong!!

[cassa333]

HI,

i am painting a room, that was a rather lurid pink, with magnolia. It has taken two/three coats to cover but some areas have gone funny and look like someone has replastered the wall and left it unfinished.

Any ideas why and what can I do to smooth it out?

Thank you

Things to check:
Did you leave enough time between coats for the paint to dry and cure?
Has paint been applied too thickly in one coat?
Was the paint well-stirred so the amounts of pigment and water were the same each time you put your brush / roller in?
It's impossible to diagnose without seeing the problem, but if paint is applied too soon to a still-wet first coat, or too thickly in any one coat, it bonds to itself, not to the surface, and so will be likely to crumble and flake off very easily.

............ also, one would need to know what sort of paint the "pink" was. There might be a reaction.
.......... and what you're using to cover it (the magnolia).

Thank you.

It is something to do with the type of pink paint and the fact that some sort of stuff!! has been splashed over the walls.

I think it will have to be rubbed down and started again.

Before you repaint try and assess what the staining is. Eg if water has penetrated the wall, or if someone rubbed their kebab all over it, you'll need to seal off the stained part. You can get paint that does this - I forget what it's called but it's dead obvious which one it is if you read the cans. Or ask in your DIY shop.
Another way round would be to hang a good plain lining paper, then paint over. You can get 'plaster-type' lining paper - very nice smooth finish like plaster - Wallrock is one brand (not to be confused with Rockwall which is an insulating product. My B&Q hid the wallrock with the insulating stuff recently).

Some pigment does this. Depends on what colour it's over.
Not Crown 'Period' is it, by any chance?
