Abstract
A method of improving the adhesion and durability of both new paint coatings, and older cracked or peeling paint coatings on an architectural surface is described. An aqueous wax emulsion (AWE) which, upon drying, forms an aqueous wax emulsion coating (AWEC), is adherent to an architectural surface as well as to new and older paint coatings. The AWEC is furthermore waterproof, and is hyper-permeable to water vapor, thereby preventing moisture-related bubbling and peeling of the new and older paint coatings.
