New Plaster

Newly applied plaster must be completely dry before starting to apply any paint! If the room has no cornice prime the walls before painting the ceiling. This ensures that you have no colour mismatch around the edge of the ceiling as the primer will be a different shade of white to standard ceiling emulsion.

Method 1

The absolute best way to prepare newly plastered or drywall is to use Zinsser Allcoat Multi-Surface Primer and Finish™. It’s a fantastic product that will do a host of things for you. It’s a high-adhesion product similar to their Bullseye 1-2-3™ product but unlike that product will provide you with a finishing coat as well. It sticks to almost anything, obliterates deep colours and is very economical. One coat is often enough but in some cases you may need additional coats.

Method 2

Add E-B™ to your initial coat of emulsion. This will help the paint stick and stop it constantly peeling away as you roll.

Method 3

Alternatively you use an emulsion paint of a suitable colour which has been diluted with clean water – usually 20%. This ensures that the emulsion will thoroughly penetrate the plaster and any moisture will be allowed to escape. Several coats will need to be applied until the surface is built up to a solid finish. 

When applying the finishing coat or coats do not dilute the emulsion but apply it as if you were painting a normal wall or ceiling.
