Characteristic crack pipe mouth to strengthen the HB polymer cement waterproof coating, in particular high performance HB construction emulsion adhesive (referred to as the HB type emulsion glue) as the main body, with a certain proportion of cement made. This product has excellent adhesion, impermeability, crack resistance, durability and resistance to acid and alkali effects. The product is non-toxic, non-polluting, convenient construction, with significant environmental benefits, the Department of a new generation of environmentally friendly waterproof material. Use 1, widely used in the exterior walls, toilet and bathroom kitchen, pool, basement, roofing and other building waterproof, anti-leakage, moisture, and other projects. 2, anti-leakage, moisture for aerated concrete, hollow bricks, porous materials such as masonry. The main technical performance bond strength: concrete, cement mortar bonding ≥ 1.0MPa. 2, Elongation: No treatment ≥ 80%. Tensile strength: No treatment ≥ 1.8MPa. 3, impermeability: 0.3MPa, 30min impervious. 4, Resistance: ≥ 0.6Mpa. Primary treatment: the substrate surface should be smooth and firm, no cellular pockmarked face, dirt and oil, the yin and yang angle made curved; before the construction of grass-roots defective parts to repair. 2, priming again: first brush the surface of the substrate HB emulsion adhesive. Coated waterproof coating: by HB emulsion adhesive: cement = 1: (0.6-0.8) of weight than mixing HB waterproof paint brush three times, the thickness of the waterproof specification requirements, each pass paints interval of approximately (1-2h to sticky hands is appropriate). Enhancement: For enhanced waterproof layer, can be woven or non-alkali glass fiber cloth for the carcass to be enhanced. 5, the amount :1-2kg / m2. The Note 1 HB emulsion adhesive before use should Stir. The cement required 425 # or more ordinary portland cement or slag cement; early strength cement should not be used. 3, HB emulsion adhesive should be stored in a cool place, shelf life of 24 months.
