Beschreibung
Zusammenfassung:	An aqueous tape joint compound including: an inorganic filler; an emulsion polymer binder; cellulose ether thickener; water; and from 0.01 to 1.3% by weight 5 based on the weight of the aqueous joint compound, water-soluble polymer or salts thereof, the water-soluble polymer selected from the group consisting of (a) polymer consisting essentially of, as polymerized units, from 50% to 100%, by weight based on the weight of the polymer, acrylic acid, and from 0% to 50%, by weight based on the weight of the polymer, second monoethylenically unsaturated acid monomer, (b) 10 diisobutylene-maleic anhydride polymer, and (c) mixtures thereof, the water-soluble polymer having a weight average molecular weight of from 1500 to 75,000 and a calculated Tg of from 80 C to 250 C; the aqueous tape joint compound being substantially free from calcium sulfate hemihydrate is provided. The invention also relates to a method for forming an aqueous tape joint compound and a method for 15 forming a monolithic surface.
