NB System

Crystalline Waterproofing Slurry (2-component)

Capilary active, crystalising cement based waterproofing slurry. Consists of two components (powder and liquid component) and can be applied with a brush or spray application. 

KÖSTER NB System sealing slurry is a mineral coating with excellent capillary sealing properties. It contains crystallising agents which penetrate deep to fill the voids and capillaries and that react with moisture and ingredients in the substrate to form crystals and thus creating the waterproofing effect, to seal off fround moisture, non-pressurized and pressurized water – on both the positive and negative side. The KÖSTER NB System sealing slurry becomes integral part with the substrate itself. Once applied to the substrate, it leaves a coating with excellent pressure- and abrasion resistance and has excellent resistance to chemical compounds. 

KÖSTER NB System is hygenic and is certified in drinking water applications. The coating is waterproof both from the positive and negative side up to a pressure of 13,8 bars. 

CE certificate EN 1504-2 standard.
