PC
PC concrete durability protection coating series is composed of base coating, medium coating and top coating. The medium coating PC-01 is an alkali-resistant coloring coating with excellent alkaline resistance, mildew resistance and algae resistance. At the same time, it can adjust and repair the concrete color difference, close to the desired appearance color of the exposed concrete, and provide beautiful coloring effect. PC-02 has high weather resistance and strong self-cleaning effect, to prevent the phenomenon of ultraviolet degradation, yellow, aging, color difference and uneven luster, and has excellent corrosion resistance, stain resistance and atmospheric corrosion resistance, maintain the natural texture and texture of the composite coating, and improve the service life of the composite coating.
1. Water-based materials, safe and environmentally friendly, easy to construct and low cost;
2. It has a color-modifying effect, beautifies the coating, and makes the concrete components have a uniform appearance;
3. Waterproof, stain-resistant, self-cleaning, prevent external rainwater from eroding the structure, and increase the service life of the concrete structure;
4. Long-term weather resistance, no whitening or discoloration, resistance to atmospheric erosion, resistance to ultraviolet radiation, and not easy to wear.
It is suitable for the durable protection and decoration of all exposed concrete buildings such as municipal administration, hydropower, railways, bridges, tunnels, etc., ensuring the durability, self-cleaning and beautiful appearance of the structure, reflecting the simple beauty of concrete;
It is suitable for color difference repair, beautification, water treatment and protection of ordinary concrete. While constructing the natural appearance of plain concrete, it improves the corrosion resistance and carbonization resistance of the building and ensures the durability of the structure.
It is suitable for the protection and decoration of high-alkaline base surfaces such as cement mortar plaster surfaces, concrete, lime plaster surfaces, gypsum products, cement bricks, etc. The main application areas are seaport terminals, cross-sea (river) bridges, water conservancy project dams, urban viaducts, high-grade highway bridges, railway bridges, tunnels, airport pavements, plain concrete buildings, thermal power, nuclear power plants, sewage treatment plants and other projects.
JC/T 1018-2020 (primer)
GB/T 9755-2014 (Mid-coat)
1. Remove the residue, scum and other impurities on the surface of the base layer, rinse it with clean water, and keep the surface clean;
2. Fill and repair the cracks and potholes on the concrete surface to keep the base surface flat. To ensure the beauty of the overall base surface, the overall base surface can be leveled with cement-based materials or putty materials;
3. Use spraying or rolling to apply primer (SK nano silicon ion permeability modifier) to the concrete base surface to effectively repair the internal concrete capillary cracks and improve the bonding strength between the upper coating and the base surface;
4. Before the construction of the midcoat, the color difference should be compared and it should be consistent with the color of the concrete. The midcoat should be diluted according to the construction requirements and the amount of water should be adjusted on site. The dilution ratio is: midcoat: water = 1:0-6;
5. When the base surface is completely dry, the midcoat is applied by spraying or rolling. The number of times of application is determined according to the site requirements, and the overall effect must be uniform.
6. After the middle coating is completely dry, the top coating can be applied;
7. Dilute the topcoat first, and adjust the amount of water on site. The dilution ratio is: topcoat: water = 1:0-0.5;
8. The topcoat is applied by spraying or rolling, and is applied 1-2 times with continuity and integrity required.
1. Before construction, cracks and uneven areas must be repaired before coating can be carried out;
2. Do not construct when the temperature is below 5℃ and the humidity is above 85%. Please avoid rain, snow and strong wind weather;
3. The workplace should be well ventilated and fireworks are strictly prohibited during operation;
4. When spraying, it is recommended to use an airless spray gun, adjust the paint output and spray fan surface to ensure the continuity, integrity and no sagging of the coating;
5. The product should be stored in a cool place and properly kept, stored and discarded. After opening, please use it up as soon as possible.
