Infiltration Po SKB-201 grams of cement-based capillary crystalline waterproofing coating is a combination of active chemicals with special cement made of light gray powder-like material, waterproof material category belongs to a kind of rigid gas-free, odorless, non-toxic, non- pollution of green materials. Infiltration g Po SKB-201 waterproof coating suitable for wet construction cement concrete base surface. As the concrete structure of the porous nature of the active material in the wet chemical action of water-based surface, through the capillary phenomenon, and use its "hydrophilic" ability to infiltrate water as carrier in concrete structures has been reached Concrete cracks and leakage in the place. Where contact with water, the catalytic reaction of cement hydration process of calcium silicate and precipitated Ca (OH) 2 reacts with calcium to form insoluble crystalline dendrite-like fiber material, the structure of pores and filling cracks are dense, so the water block, to waterproof the purpose of raising the density of concrete and self-waterproof. Features: 1, suitable for wet cement concrete base surface construction, in welcoming the back surface of the water can be used; construction in rough surface without protective layer can be directly used to backfill the basement wall; 2, with superior penetration, the internal penetration in the concrete mold, can not easily be damaged, with exceptional ability to repair itself, repair cracks less than 0.4mm. Can penetrate the wall surface, and blocking all full of small pores, forming a unique protective layer, 3, long-term impermeability and tolerance of strong water pressure, an inorganic material does not exist the problem of aging, high temperature, low temperature, anti-freeze, salt and corrosion and air pollution can cause damage, and concrete with life; 4, AAR, to prevent chemical corrosion of concrete structures damaged, but the protective effect of reinforced concrete without damage to the expansion of the role; 5, Tu rinse the surface after the coating is then covered with brush directly to the other coatings, can be directly bonded to the tiles and other decorative materials. When used for interior walls, especially when used in basement waterproofing, coatings can withstand high water pressure, water in both the role of external structures, but also decorative; 6, non-toxic, environmentally friendly products, direct contact with drinking water; 7, simple construction, easy operation, fast, save construction period, construction was not required to do protective layer, reducing total cost. Use: 1, waterproof protection of concrete structures, can be used in bear positive and negative pressure of the wall, can be located in basements or below the horizontal wall; green roof 2, can be used as silos, cooling tower water, anti-chemical erosion corrosion of concrete structures, etc.; 3, can be used as irrigation channels of water, repair materials, can be used as dams, locks and waterproof waterproof wall material, water treatment plants for water treatment for water pipes and shafts; 4, for swimming and water tanks, water pool of water, for basic walls and floor, lift and water wells of water, used for grain storage and food library, kitchen and toilet and bathroom in the water, for cable channel, tunnels, ports, terminals and other waterproof. Construction method: 1, Scraping method a) Primary treatment: the concrete base should be smooth and free from loose, peeling, cracking, hollowing, loose and other defects, if defects, cracks, patches should Honeycomb; base surface should be rough, clean, for the use of steel or surface oil, paint, paint surface must be treated by using steel wire brush cleaning, hammering, blasting other means to remove the oil, and rinse well with water; construction before concrete surface should be sprayed water, kept moist, but clearly should be avoided water. b) Preparation and construction of coating: (recommended dosage is 0.8 1.5kg/m2) will THINKABLE waterproof coating and the ratio of clean water mixed as required, stir, then the required amount of brush or spray evenly to the primary surface (the back water or water face is available.) Brush, the paint and water with the ratio of 1:0.4, with a semi-hard brush or nylon brush bristles have been coated to pre-process the concrete surface, brushing should ensure uniform thickness, seamless coating. Spraying, the paint and water mixture ratio was 1:0.5 0.6 (depending on spray equipment may be), the spray gun nozzle and the distance between base level should not exceed 0.5m, and should be perpendicular to the basal plane spray. When the first brush, the initial setting to be coated (touch dry) brush a second time, as shall be first surface has dried spray some water. Good mixing paint, from the beginning of water should be used within 25 minutes, during the construction process, the mixture should be stirred occasionally, and not to have a good coating with additional water. General amount of brushing the paint again 0.5 0.8kg/m2. Temperature below 4 °C or before rain can not works. c) coating conservation: the initial setting up enough to be a hard surface coating, the spraying of a clean water conservation, conservation started 3 to 4 days, daily spraying of water to the coating of not less than 4 to 5 times, so that in wetting condition, but not soaked in water conservation. Covered with wet straw bag is best qualified conservation. In summer, experience hot weather, to increase the number of water spray; in winter frost conservation should be stamped idiot. Reservoirs, swimming pools and other water storage structures should be at least 7 days before they can conserve water use. d) Backfill: Backfill for underground works needed in construction backfill wet after 36 hours, 7 days can not backfill dry soil, in order to avoid affecting THINKABLE coating performance. 2, sprinkle dry method Dry goods scattered in half an hour before pouring concrete, the material according to the amount of 1.5 2.0kg/m2 spread evenly on a pre-wet the cushion (floor outside the water). In the concrete surface is still wet when not completely solidified, the material according to the amount of 1.5 2.0kg/m2 spread evenly in the base surface, and scrape it with concrete with closely, this method is used in a variety of concrete pouring body. Coating without additional conservation, in accordance with the concrete curing methods.
