Repel Cure is recommended for use on new or existing unsealed Pool Decks, Exposed Aggregate Concrete, Broom Finish Concrete, & other unsealed porous concrete & masonry surfaces. Other uses may be acceptable. Repel Cure is a dual functioning chemical reactive curing compound and water repellent with a low viscosity for better penetration on concrete substrates. Repel Cure’s unique formulation provides superior water and salt resistance compared to standard sealers used to protect exterior concrete. Improved resistance to deicing road salts, salt water pool systems, rain, sleet and snow are achieved with our advanced chemical reactive formula. Repel Cure also meets cure & seal specs ASTM C-309, Type 1, Class A & B, AASHTO Spec M-148, Type 1, Class A & B so it can be applied directly to fresh poured concrete after all surface water has dissipated.
