Abstract
The fresco coating composition which, when admixed with a cement-based plaster, produces a material for troweling, to obtain fresco finish. The composition is made by combining: a) 10 to 24% by weight of at least one binder selected from the group consisting essentially of an acrylic polymer binder or an acrylic polymer binder and an acrylic polymer cross-linking binder; b) 20 to 50% by weight of water; c) 2 to 8% by weight of a filler selected from the group consisting essentially of cellulose, paper pulp, or mixtures thereof; d) 20 to 40% by weight of at least one water-insoluble particulate extender including silica sand; e) 0.5 to 2% by weight of a thickening agent; f) optionally at least one of a solvent, a coalescence promoter, a foam inhibitor, a biocide and mixtures thereof.
