Waterproof repair mortar for universal use. It is used for sealing and filling cavities in concrete. The mortar adheres very well to the substrate and is hydrophobic. Together with the SB Haftemulsion additive, it is used as a PCC repair mortar.

Properties

• waterproof mortar for repairs and sealing
• very good adhesion, also to old mineral building substrates
• with the addition of Koester SB Haftemulsion emulsion used as a concrete repair mortar of PCC type (Polymer Cement Concrete)
• based on cement with increased resistance to sulphates

Application

• performing waterproof repairs, facets and restorations in concrete
• making plaster in airtight
• leveling unevenness or filling joints before insulation with bituminous masses, also with water under pressure
• making watertight profiles (facets) at the junction of walls and the foundation in - before insulation with bituminous masses (Bikuthan 2K, Deuxan 2K) or with K STER NB 1 sealing micro-mortar
