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
