. Implementation standard: "Cement-based penetrating crystalline waterproof coating"
. Product Introduction
. Cement-based Penetrating crystalline waterproof coating is a powdery waterproof coating with penetrating crystallization function, which is based on selected high-quality cement and mixed with special inorganic materials and active polymers with high penetrating activity. The waterproofing mechanism mainly utilizes the porosity of the concrete structure. In the presence of water, active compounds penetrate into the interior of the concrete, forming a large number of water-insoluble long chain crystals in the pores and cracks, filling the capillary channels, thereby making the concrete dense. ,water proof. And because the active material can be activated by water many years later, new crystals can grow in secondary cracks. Therefore, the cement-based penetrating crystalline waterproof coating has the ability to self-heal multiple times and improve impermeability, and is suitable for applications that require permanent waterproofing. Waterproofing and repair of the internal and external surfaces or bodies of various concrete structures.
. Product Features
. Non-toxic and odorless, environmentally friendly product, easy to construct.
. It has super penetration ability and can penetrate into the concrete to form crystals and repair cracks smaller than .
. Construction on wet base surface is simple and requires no protective layer, saving time and labor.
., strong impermeability, inorganic material, long aging resistance and lifespan.
., can resist the erosion of most chemical substances, and has strong corrosion resistance.
., can achieve multiple self-repairs, and has long-term waterproofing effect.
., single-component powder, easy to transport and store.
. Scope of application
. Can be widely used in the waterproofing and protection of concrete structures in underground structures of industrial and civil buildings, subways, civil air defenses, roads and bridges, pools, sewage pools, hydropower stations, nuclear power plants, water conservancy projects, etc. , it is also suitable for waterproofing and plugging of concrete structures, especially suitable for waterproofing and plugging of water surfaces at the back (facing) of underground buildings (structures). Special recommendation: Suitable for structural parts prone to micro-crack leakage.

. Debris, unevenness and cracks must be leveled first, and the yin and yang angles should be made into arcs. Before construction, the base surface should be moist but without open water. < .Construction: Stir according to the mass ratio of powder:water:.3 until it becomes sticky. Use a scraper or brush to apply the prepared paint in two or more coats to the treated and pre-wetted concrete surface. The second coat must be applied while the first coat is still wet. If it is found that part of the base surface is still dry during the construction process, it must be re-moistened. < r. Maintenance: The coating should be fully maintained. After applying the coating, it should be covered with damp burlap in time to ensure that the coating is moist. After the coating is hardened, it can be cured by spray and covered with burlap. It must be cured for several hours. . Precautions
. . Cannot be used in rainy days and icy climates. It should not be used at ℃. In the sun, when the temperature is high, the coating must be sprayed with water to moisten it.
. The coating slurry should be used up within 3 minutes after mixing, and should be stirred continuously during use. It is strictly forbidden to add additional water.
. Watering and curing is prohibited before the coating hardens.
. Do not add too much water to the ingredients. Adding too much water will cause excessive hydration of the cement, resulting in bulging, delamination, powdering, cracks, and low strength of the coating.
. Reference dosage
. Reference dosage per square meter: ., depending on the construction site and base surface conditions.
