Use of ethylene oxide/propylene oxide block copolymers in hydraulic

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.

Joint-sealing materials and coating materials which contain aqueous dispersions of polyacrylates or acrylate copolymers, plasticizers and the usual additives, such as pigments and the like, have excellent properties particularly with regard to brushability, smoothing behavior and wash-out resistance when they contain a nonionic cellulose ether selected from the group consisting of hydroxyethyl cellulose, hydroxyethyl-methyl cellulose, hydroxypropyl-methyl cellulose and hydroxypropyl cellulose having a Brookfield viscosity in a 2% aqueous solution at 20.degree. C. of at least 3000 mPa.s.
