Permanently plastic, damp and waterproof sealing compound for waterproofing against pressurized water
Koster KB-Flex 200 is a permanent plastic sealing compound ideal for sealing pipe and cable penetrations, cavities and for custom detail waterproofing solutions against moisture and pressurized water.
Prior to application, the Koster KB-Flex 200 cartridge is laid into warm water and heated to approx. + 30 °C. This ensures that the material has the optimal consistency for application. The application area flanks must be thoroughly cleaned from the inside so that they are free of dust, sand and other loose particles.
