description The present invention relates to an aqueous coating composition providing improved adhesion to friable surfaces such as chalky weathered paint surfaces and masonry surfaces and to a method for producing a coating on a friable surface. An aqueous coating composition having improved adhesion to friable surfaces is provided. The aqueous coating composition includes a plurality of polymeric particles having a particle size of less than 120 nanometers, and containing at least two polymers, one of which contains, as polymerized units, acid functional monomers, water soluble monomers, or both. Optionally, the aqueous coating composition includes a nonionic surfactant. In addition, a method for improving adhesion to friable surfaces by using the aqueous coating compositions of the invention is provided.
