NOVELTY - Concrete crack repair waterproof coating comprises 50-58 pts. wt. silicate cement, 15-25 pts. wt. microbead powder, 4-8 pts. wt. water-repellent, 5-10 pts. wt. acrylic powder, 10-15 pts. wt. graphene nanosheets, 15-25 pts. wt. quartz sand, 1-2 pts. wt. chopped glass strands, 0.05-0.10 pts. wt. defoaming powder, and 0.5-1.0 pts. wt. filler. USE - Concrete crack repair waterproof coating. ADVANTAGE - The concrete crack repair waterproof coating has enhanced performance than existing concrete crack repair waterproof coatings. It uses microbead powder with stable physical and chemical properties and strong aging resistance, thus improving compressive strength and performance of coating. The water repellent has good waterproof effect, which allows waterproof coating to repair concrete crack, so that surface of repaired waterproof coating forms thin waterproof film to prevent water from entering. The acrylic powder provides strong adhesion, good flexibility and good synergistic waterproof effect to coating. The chopped glass strands increase tensile strength and elastic modulus of product.
