KÖSTER Sanierputz

Renovation Plaster

KÖSTER Sanierputz is a salt-resistant renovation plaster designed for walls with high salt content and moisture levels. Its wide-pore structure provides excellent durability and does not require additional surface treatment before applying finishing layers.

This renovation plaster prevents condensation, improves thermal insulation, and is highly effective when used after horizontal waterproofing treatments such as KÖSTER Crisin 76 Konzentrat or KÖSTER Mautrol 1K/2K. It reduces the risk of condensation in spaces with high humidity when used alongside mineral waterproofing slurries like KÖSTER NB 1. Additionally, Sanierputz serves as a hydrophobic external plaster, especially for facades with a protective base coat like KÖSTER Sperrmörtel.
