A broad-porous, water-repellent, diffusion-open, cement-based, salt-resistant white renovation plaster. They are intended for salty and damp walls. The product allows for a glass-free desalination and drying of masonry. It has very good workability.
Properties
- salt-resistant
- high strength, making the product suitable for plastering masonry, even with high salinity and moisture.
- thanks to its high porosity and hydrophobicity, the renovation plaster allows for glass-free drying and desalination, even at high salinity levels
- protects against the formation of condensation water
- improves thermal insulation
- does not contain light fillers, so no additional surface treatment is required before applying subsequent layers (e.g. diffusion open wallpapers or paints)
- complies with WTA requirements
Application
- repair and renovation of salty and damp walls, including after restoring horizontal insulation using the injection technique, e.g. with Koester Crisin Creme or Koester Mautrol 2K
- Useful when no papering or painting the plaster is planned
- reduces the formation of condensation water after sealing with a mineral sealing micro-mortar (e.g. Koester NB 1) in rooms with high air humidity
- decorative, water-repellent exterior plaster; in advance, it is recommended to apply a sealing plaster in the plinth area up to 30 cm above the ground (Koester Sperrmortel) in advance
