SG 68 undercoat plaster is a complementary product to the Baumit Bayosan renovation system. It is used to remove large inequalities / or as a salt storage in case of heavy loading of the substrate. Due to good stability, the plaster is easily applied to relatively thick layers and safely fills even large defects. plaster is used only in cases when the thickness of the total layer of the plaster system in renovation works exceeds 4 cm. Otherwise, it makes sense to use typical renovation plasters for leveling or as a primer. SG 68 plaster can only be used as a primer plaster and requires covering at least 15 mm thick with a layer of renovation plaster.
