Concrete Pool Shell Protector is a non-hazardous, user friendly, permanent, clear treatment/preservative sealant solution for new or old concrete pool shell installations. It includes a highly reactive catalytic agent in a water-borne proprietary colloidal silicate base that produces a silica hydrogel inside concrete's matrix that will reduce permeability and porosity and help preserve its embedded steel. Concrete Pool Shell Protector reduces peeling, cracking and loss of bond caused by capillary moisture or internal chemical reactions that can cause bond failure for plaster application. Concrete Pool Shell Protector will arrest or at least severely retard concrete being deteriorated by alkali-aggregate or alkali silicate reactivity.
