Cement-based waterproof paints are waterproof coatings permeating crystallized paints based on special cement, quartz sand, etc., and seep into powdered waterproof materials made of various active chemical substances. The silicate ion dissolved in waterproof coatings using the solid cement base spreads with surface water permeating in concrete and chemically reacts with calcium ion in concrete to produce insoluble calcium silicate in water hydraulics (cranch crystals) with crystals filled with porosity and integrated into concrete, clogged through the porosity lanes inside the concrete, thus condensing the concrete and preventing water leakage. In addition, cement-based water-proof coatings have catalytic properties, and once water encounters can produce a continuous chemical reaction, the crystals that are generated grow and fill the porosity of the concrete's interior, so that concrete structures, even if partially damaged, can produce crystallization and self-remediation (0. 4 mm...
