Abstract:
1. 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; 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; and wherein the blend is adapted to form a one-coat composition to be coated on a substrate selected from the group consisting of concrete, wood, stone, cement, stucco, cement based products and combinations thereof.
