An aqueous composition for coating cementitious or masonry substrates is provided. When dried, the coating composition has high gloss and low dirt pick-up. The composition includes at least one emulsified polymeric binder; at least one water-soluble silicate; at least one alkyl siliconate; at least one pigment, optionally at least one filler; optionally at least one paint additive; and water. The pigment volume concentration (PVC) of the aqueous composition is 40 weight % or less.

The present invention relates to primer compositions in powder form that comprise a dispersion powder based on an acrylate polymer having a glass transition temperature in the range from 50 C. to +30 C. and cement. The compositions of the invention are notable for good water barrier effect, good dust-binding capacity, and a low tendency toward salt efflorescence. The encompositions find use in the priming of masonry, concrete, rendered surfaces, abraded render, plaster surfaces, wall blocks, wood, and ceramic tiles. They can also be used as adhesion promoters with nonabsorbent substrates such as glazed ceramic or glass tiles, metal surfaces, or surfaces of plastic.

A roofing membrane is provided that includes at least one substrate at least partially impregnated with a first asphalt coating composition and a liquid parting agent emulsion applied to the upper surface of the asphalt-coated substrate. The liquid parting agent emulsion comprises one or more thermoplastic polymers and about 15 wt. % to about 40 wt. % of at least one mineral filler, based on the weight of the total solids in the emulsion. The first asphalt coating composition is free of oxidized asphalt.
