Intermediate resin blend for improved coatings

An intermediate resin blend useful for forming a one-coat composition for coating or sealing a substrate comprising:

• a film forming hydrophobic acrylic resin that cures under ambient conditions via self cross-linking, has an average particle size of less than about 0.1 microns and has a glass transition temperature greater than about 45° C.;
• a water repellency additive comprising silicic acid, diethoxyoctylsilyl trimethylsilyl ester and triethoxyoctylsilane in an amount sufficient to increase both the water repellency and vapor transmission rate of the acrylic resin;
• a plasticizer;
• a foam control additive;
• a surfactant;
• a mar resistance additive;
• wherein the intermediate resin blend has a coalescing requirement of from about 5 to about 15 weight percent cosolvent based on the total resin solids weight;
• wherein the blend has a vapor transmission rate greater than that of the acrylic resin alone;
• wherein the foam control additive is a substituted siloxane emulsion, the surfactant is a low molecular weight organofunctional silicone and the mar resistance additive is an ethyl methyl methyl(2-phenylpropyl) siloxane.

• from about 5 to about 20 weight percent of a cosolvent to form a coating composition;
• and
• wherein the coating composition is adapted to be coated on a substrate selected from the group consisting of concrete, wood, stone, cement, stucco, cement based products and combinations thereof.
