1. NEWLY PLASTERED WALLS SHOULD BE LEFT TO DRY COMPLETELY BEFORE ANY PAINT OR PRIMER ARE APPLIED. YOU WILL KNOW THE PLASTER IS DRY WHEN ALL DARK PATCHES HAVE DISAPPEARED AND THE COLOUR OF THE PLASTER TURNS TO A LIGHT PINK. IN AN IDEAL WORLD THIS SHOULD BE LEFT FOR A FURTHER WEEK TO ENSURE THE PLASTER HAS DRIED FULLY BEFORE APPLYING THE PRIMER.
2. THE FIRST COAT ON ANY NEW PLASTER SHOULD BE A PRIMER WHICH HELPS SEAL THE PLASTER AND CREATES A BETTER SURFACE FOR PAINT TO ADHERE ONTO. NOT USING A PRIMER WILL RESULT IN THE PLASTER SOAKING UP ANY PAINT APPLIED TO IT. FOLLOWING INSTRUCTIONS ON THE TIN OF PRIMER, APPLY THE SEALER TO THE WALLS USING A ROLLER.
ITS ALSO POSSIBLE TO USE A STANDARD WHITE EMULSION PAINT IN PLACE OF THE PRIMER BY MIXING THE PAINT WITH WATER. THIS METHOD IS AS EFFECTIVE AND CAN BE A CHEAPER OPTION. MIX AROUND 70% PAINT AND 30% WATER IN A KETTLE AND APPLY TO THE WALLS USING A ROLLER.
2. ALLOW THE COAT OF PRIMER TO DRY AS STATED ON THE TIN OR FOR AROUND A DAY BEFORE APPLYING YOUR FIRST COAT OF PAINT.
