Early-rain-resistant joint-sealing compounds containing (a) aqueous polymer dispersions (I), (b) nonionic cellulose ethers (II) selected from the group consisting of hydroxyethyl, hydroxyethyl-methyl, hydroxypropyl-methyl and hydroxypropyl cellulose, and (c) optionally typical additives, such as fillers, pigments, plasticizers, extenders, thickeners, foam inhibitors, dispersion aids, pH regulators, preservatives and anti-aging agents, which can be produced by thorough mixing of (I) with the other constituents. To be able to introduce (II) in quantities above the solubility limit, the joint-sealing compounds are characterized in that (II) is suspended in retarded form in small quantities of water and is added and intermixed after suspension.
