Clay plaster
Single or multilayer basecoat plaster for interior application. For 25 years now clay basecoat plaster with straw has been the classic for applying thick layers, e.g. on rough masonry, for wall panel heating or for restoration work in historical buildings. Up to 35 mm can be applied in a single operation. The material is highly workable, it sticks overhead, and is suitable for gap filling and much more. Clay basecoat plaster with straw is also a substrate for all coarse and fine Claytec clay topcoat plasters. Dry mortar never expires and can also be used with plastering machines.
Application
Single-layer topcoat plaster for interior use. Manual or machine plaster on CLAYTEC clay basecoat plaster, clay building boards and other sufficiently flat surfaces made of suitable building materials.
