The former are used for rooms in which insignificant humidity is observed, so they cannot be used in the bathroom. Cement mixtures are suitable for any room. However, the mixtures from gypsum create a thicker screed, thanks to which large and visible irregularities are eliminated. Choose a special mixture for a certain type of work.
