SK-3
SK-3 nano-silicon ion permeability modifier can penetrate deeply into the concrete and cracks, react chemically with the calcium ions in the concrete, and generate hydrated calcium silicate crystals that fully fill the pores and tiny cracks inside the concrete (the solution itself can also solidify), making the concrete denser, thereby being able to repair existing cracks, improve the waterproof and anti-seepage grade, cut off the seepage channels, and fundamentally solve the problems of building leakage and cracks.
1. Improve the density of concrete and repair minor cracks;
2. Both the water-facing and water-receiving sides can be used, but the water-facing side has better effect;
3. Green and environmentally friendly, meeting the standards for drinking water projects;
4. Both the material itself and the crystals are inorganic substances, do not age, and have the same lifespan as concrete.
It is suitable for repairing static cracks in concrete with a width of less than 0.4mm, except for cracks that are leaking. It is especially suitable for the quick and simple repair of large-area mesh-like through cracks in flat structures (roof panels, top plates, etc.).
1. Check and clean the base. Use high-pressure or low-pressure washing machines or brushes to clean the base according to different construction surfaces;
2. Paint "three waters and two liquids" construction. Sprinkle water on the cracks until the internal water is saturated. After there is no visible water on the surface of the base surface, spray the first layer of material, with a dosage of 150~300g/m², and spray more material on the cracks. Set the curing time (about 0.5-1h) according to the construction base surface and climate. During this period, avoid the construction base surface from drying, and sprinkle water appropriately when it is dry. In order to accelerate the penetration of the material, low-pressure watering should be evenly carried out again. After there is no visible water on the surface of the base layer, spray the second layer of material, with a dosage of 150~300g/m², and spray more material on the cracks. In order to accelerate the penetration of the material, low-pressure watering should be evenly carried out again.
3. Inspection, repair and acceptance. If the cracks are not completely repaired after the water test, the material can be constructed again according to the above steps until they are completely repaired.
