What is the difference between cement-based permeable crystalline waterproof coating and JS waterproof coating?

1. Cement-based osmotic crystallization is a rigid waterproof material, JS waterproof coating is a flexible waterproof coating, J is the abbreviation of polymer, S is the abbreviation of cement-based, and JS waterproof coating is the abbreviation of polymer cement waterproof coating. \x0d\2。 The implementation standard of cement-based osmotic crystallization is GB 18445-200 1. The implementation standard of JS is GB/T23445-2009. \x0d\3。 Both materials are directly coated on the base, and the osmotic crystallization directly penetrates into the tiny holes of the concrete base to achieve the waterproof and moisture-proof effect. JS forms a waterproof coating on the base to achieve the waterproof effect. \x0d\4。 Osmotic crystallization has no ductility and flexibility, which easily leads to water leakage. JS has certain flexibility, extensibility and low-temperature flexibility, is not easy to crack, and has relatively superior waterproof performance. \x0d\5。 It is suggested that the two materials be used together for better effect. The concrete base should be coated with osmotic crystallization first and then JS three times, and the film thickness is about1.5 mm. These are two waterproof works, and the waterproof quality is better.
