Silicate-water based liquid. The active ingredients penetrate deeply into the substrate and react to form an insoluble compound. The pores are permanently sealed through the crystallization process. Used in combination with KOSTER KD 1 Base and KOSTER KD 2 Blitz Powder for the negative side waterproofing of cementitious surfaces such as internal basement waterproofing. The KOSTER KD System stops flowing water and forms a permanent waterproofing layer on masonry and concrete.
