Clay plaster
Single- or multi-layered basecoat and topcoat plaster for indoor use. Mineral clay plaster is a basecoat and topcoat plaster all in one. It contains angular fractured sand to ensure strength. After application, the mortar contracts quite quickly and can be worked with again after a short period. If used as a basecoat plaster, it is suitable for all coarse and fi ne CLAYTEC clay topcoatplasters, e.g. YOSIMA. If used as a rough or even smooth topcoat with a mineral, straw-free surface texture, it can be painted with the CLAYFIX clay paint system.
