Description
A salt and pressure resistant restoration plaster for the restoration of heavily moisture and salt burdened substrates. Due to its high porosity and hydrophobicity, it allows for the damage free drying and de-salting of masonry even in the case of high salt contents.
It improves the insulative properties of the wall and therefore helps prevent the formation of condensate. The plaster is free of light fillers and therefore requires no further surface treatment prior to the application of breathable paints or wallpaper which is open to vapor diffusion. CE marked to BS EN 998-1. Substrates must be primed with Köster Polysil TG 500, with a minimum consumption of 120 g/m².
