Abstract:
A method of modifying a masonry composition comprising:treating the masonry composition with a polymer;wherein a composition comprising the masonry composition and the polymer consists essentially of the masonry composition, the polymer, and optionally, at least one component selected from the group consisting of fillers, inorganic pigments, organic pigments, and water;wherein the polymer comprises as polymerized units: a) from 20 to 100 parts by weight of at least one C.sub.12 to C.sub.40 alkyl ester of (meth)acrylic acid, b) from 0 to 80 parts by weight of at least one ethylenically unsaturated monomer, and c) from 0 to 80 parts by weight of at least one ethylenically unsaturated acid containing monomer or salts thereof, provided that when the at least one ethylenically unsaturated monomer is selected from the group consisting of hydroxyethyl (meth)acrylate and hydroxypropyl (meth)acrylate, the combined total level of hydroxyethyl (meth)acrylate and hydroxypropyl (meth)acrylate ranges from 0 to 40 parts; and wherein the polymer is an emulsion polymer prepared by emulsion polymerization.
