GECO CEMENT plaster is a pre-mixed, breathable cement-based plaster with mineral fibres and a fine floated finish, classified as a renovation mortar (EN 998-1 R). It is used to plaster damp walls and ceilings, indoors and outdoors, in one or more coats.
It goes on thick – up to 30 mm (1.18 in) per coat – without sagging or cracking: anti-sagging additives keep the surface uniform, mineral fibres improve impact resistance and controlled shrinkage limits fissures. Its capillary water absorption is class W0, and because it is vapour-permeable it lets the wall dry out.
After 1.5-2 hours it can be floated to a smooth or slightly rough finish; after 24 hours it can be painted or covered.
