Waterproof Powder is composed of waterproofing additives, dispersed in inert fine filler. It is an integral powder-waterproofing admixture used for waterproofing of concrete and cements plasters, because it makes concrete cohesive and reduces porosity and improve water tightness. This is composed of waterproofing additives, dispersed in inert fine filler. Waterproof Powder is an integral powder-waterproofing admixture used for waterproofing of concrete and cement plasters, because It makes concrete cohesive, reduces porosity & improve water tightness.As an effective pore filler, helps to fill capillaries and pores to prevent water seepage. Makes the mix cohesive and denser, hence the concrete and plaster has reduced permeability.
