What is the most efficient method for tackling calcimine painted surfaces like ceilings?
Since calcimine paints contain little or no binder, they tend to be very chalky. Clean the surface with a household cleaner to remove as much chalk as possible. Rinse thoroughly. Then apply a primer that secures adhesion on chalky surfaces, such as LOXON Conditioner. Follow with two coats of the topcoat of your choice.
