Painting Plasterboard

leevis · 30 Mar 2015

Hi All
Put up a new ceiling in the hall and used the mud method on tapered plasterboard. Almost now at the point where I will be painting it.
Obviously I need to seal the plasterboard, now I could buy plasterboard sealer but this is expensive and was told by a colleague to do the following:
2 coats of 25% emulsion and 75% water
2 coats of 75% emulsion and 25% water
and then as many 100% emulsions coats as required.
Does this sound right? Don't want the plasterboard to bubble up etc.

Christ, that's a lot of coats.

On the couple of occasions I've painted plasterboard, I just gave one mist-coat of 75/25 paint/water, and then a couple of normal coats.

Just apply one mist, and crack on with the painting.

One mist coat and as many full top coats as required.

This is bare plasterboard right, not plastered

Yes; there's nothing special about plasterboard - don't worry about it.

No need to go mad with the water,add about 20% water max for the 1st coat and then 2 more coats with 10% water added should give a good finish
