How Do I Paint Chalky Surfaces?
Chalky wall surfaces occur when the previously painted surface starts to break down due to either UV or environmental action. This results in the film build breaking down and becoming unstable characterised by a chalky or dusty feel to the surface with some areas of obvious flaking. This can occur on both internal and external surfaces.
The critical element in painting these surfaces is correct preparation.
