Joint sealing or coating materials containing aqueous dispersions of polyacrylates, plasticisers and customary additives, such as pigments and the like, have excellent properties, in particular with regard to the spreadability and the smoothness characteristics if they contain nonionic cellulose ethers from the group comprising hydroxyethyl-, hydroxyethylmethyl-, hydroxypropylmethyl- and hydroxy- propylcellulose and having Brookfield viscosities of at least 3,000, in particular at least 5,000, mPa.s in 2% strength aqueous solution at 20<o>C.
