How to paint white set plaster

 

One of the biggest "hot potatoes"for painting in Western Australia is how to paint white set plaster walls. Up until recently It has always been difficult to get an official ruling on the most correct method of painting one of the building industry's most contentious surfaces. Recently the Master Builders Association in association with the major paint manufacturers conducted a review on the best trade practices to ensure than when it comes to painting fresh white set plaster walls you are doing so with a system that will not peel or deteriorate in the future.

Basically when it comes to white set plaster there are several factors that can have a detrimental effect to your paintwork if you're not careful with your preparation.
The main issues that you need to look for to achieve the best results are
Residual moisture
Residual alkalinity
Residual efflorescence
Plaster drumminess
Plaster incoherence and softness
Plaster powderiness
An overall assessment of surface soundness
