Koester - SB Haftemulsion Koncentrat elasticising emulsion

Flexible emulsion for universal use for sealing slurries, plaster, mortars, concrete. It reduces absorbency and increases frost resistance of mortars and plaster. Moreover, it increases plasticity and improves workability of mortars. It does not contain solvents, fillers or softeners. Used to perform renovation rendering (sprats).

Application

• the product is used wherever exceptionally good adhesion between mortars, mineral slurries, concrete, plasters and the existing mineral substrate is required
• the preparation makes the mortars plastic, changes the water absorption by mineral systems, improves the workability of fresh mortars
• bound plasters and mortars are much more resistant to frost, salt and other aggressive substances
