Crack-bridging, stable, 2 component, polymer modified bitumen thick film sealant for waterproofing external (positive side) substrates.

KÖSTER Deuxan® 2C is a two component polystyrene-free, fibrated, polymer modified bitumen thick film sealant for the safe waterproofing of building structures. The coating bridges cracks of the substrate safely and against pressurised water. KÖSTER Deuxan® 2C is radon-proof.

Field of application
KÖSTER Deuxan® 2C is designed for the safe and permanent outside waterproofing of basement walls, foundations, floor plates etc., for intermediate waterproofing of balconies and terraces. Since applications of waterproofing are carried out depending on the water-loading conditions, the loading conditions have to be determined exactly by the planner prior to the application.

Deuxan being applied

KÖSTER Deuxan® 2C has been successfully used in load conditions of pressurised water for many years (Consumption min. 6 kg / m²). The coating is also suited for the intermediate waterproofing underneath screeds and for bonding insulation- and drainage- boards.
