Fast-setting repair mortar, slightly intumescent. It is used for sealing and filling cavities in concrete. The mortar adheres very well to the substrate and is hydrophobic. With the addition of SB Haftemulsion, used as a repair mortar of the PCC type. The setting time is 15 minutes.

Properties

• waterproof
• fast-setting
• slightly swelling
• very good adhesion also to old mineral building materials
• with the addition of Koester SB Haftemulsion emulsion used as a PCC (Polymer Cement Concrete) repair mortar
• based on cement with increased resistance to sulphates

Application

• making watertight facets, repairs and restorations
• leveling out unevenness or filling the joints before insulation with bituminous masses, also with water under pressure
