How do i paint new plaster

Postby stephen8 » Sat Jun 30, 2007 6:43 pm

We have had the wall plastered a few days ago and brown stains have appeared. We had previously cork tiles on the walls which have been skimmed. The plasterer had problems when applying the unibond and the plaster kept bubbling and then he used something i think it was called spa which he said would be more effective. I have bought sealant for the new plaster but understand that i might need to use microprous paint to allow the plaster to breath.How long do i wait and which do i apply first, the sealant or the microporous paint. As the plaster is drying some of it is leaving a salty,grainy substance on the walls with rust coloured staining coming through in some areas.

Can anyone help please. :?

Wait for the plaster to dry
Treat any stains with white undercoat
Just thin the first coat of emulsion down to give a wash coat
let it dry
any brown marks coat with undercoat
sand down the salty,grainy substance undercoat it

If you like put a roller in undercaot and do the whole wall or walls
smells a bit but should kill any stains
main thing is let it dry thats undercoat emulsion or plaster.

You can purchase DULUX obliterating emulsion which is for new plaster and there isnt much this wont cover even in one coat. :lol:
