Abstract
Joint-sealing and coating compounds containing aqueous dispersions of polymers and copolymers, except for polyacrylates and acrylate copolymers, plasticizers and typical additives, such as pigments and the like, show excellent properties, particularly in regard to spreadability, smoothing behavior and resistance to spray water of uncured surfaces of these compounds providing they contain nonionic cellulose ethers selected from the group consisting of hydroxyethyl, hydorxyethyl-methyl, hydroxypropyl-methyl and hydroxypropyl cellulose having a Brookfield viscosity (2% aqueous solution at 20.degree. C.) of at least 3,000 mPa.s.
