Verified by manufacturer 5 months ago
Grey salt and moisture resistant restoration plaster for internal and external use.
Application
For internal and external use. Suitable for the repair of moisture and salt damaged masonry, also after the post installation of a horizontal barrier with Koster Crisin 76, Koster Mautrol, Köster Mautrol 2C or Koster Mautrol Flex 2C.
It can be applied to reduce the formation of condensate after waterproofing rooms with high humidity using mineral sealing slurries such as the Koster KD System or Koster NB 1 Grey. It can also be used as a water repellent exterior plaster.
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 Koster Polysil TG 500, with a minimum consumption of 120 g/m².
