Surface Preparation
It is crucial that ample time is allowed for the concrete / plaster surfaces to dry out. High moisture content is a common cause for premature paint failures, such as blistering, discoloration, etc. As concrete/plaster are alkaline in nature together with the presence of salts and moisture which may cause paint systems to fail prematurely. Masonry surfaces must be reasonable dry and free from oil/grease and other contaminants before an appropriate Seamaster Exterior Wall Sealer is applied.
Surface must be dry and free from any structural damages. Wash the surface to remove any vegetable growths, stains, debris and powderiness by high pressure water jet.
For poor paintwork which is powdery, chalky and poor in adhesion, it is crucial to remove the old paintwork by scraping or by brushing with a stiff bristle brush before the full painting system is applied.
