Characteristic crack, nozzle strengthen the HB polymer cement-based waterproof coating, based on specific high performance HB construction emulsion adhesive (referred to as HB emulsion glue) as the main, with a certain proportion of cement made. The product has excellent adhesion, impermeability, crack resistance, durability, and acid and alkali resistance effect. The product is non-toxic, non-polluting, easy construction, has significant environmental benefits of a new generation of green waterproof material. Purpose, widely used in the exterior walls, toilet bath kitchen, pools, basements, roofing and other building waterproof, anti-leakage, moisture and other projects. 2, aerated concrete, hollow bricks and porous materials such as masonry against leakage and moisture. The main technical performance, bond strength: concrete, cement mortar bonding ≥ 1.0 MPa. 2, the elongation at break: the no treatment ≥ 80%. Tensile strength: no treatment ≥ 1.8MPa. 3, impermeability: 0.3MPa, 30min impervious. 4, Resistance: ≥ 0.6Mpa. Use 1, the primary treatment: the substrate surface should be smooth and firm, non-cellular, pockmarked face, no dust and oil, made of yin and yang angle arc; pre-construction to repair defective portion of the grass-roots level. 2, end of plastic coated: first brush again HB emulsion adhesive on the substrate surface. Coated waterproof coating: by HB Lotion glue: cement = 1: (0.6-0.8) weight than mixing HB waterproof paint brush three times the thickness of the waterproof specification requirements, each time coating interval of approximately (1-2h to sticky appropriate). 4, enhanced treatment: For enhanced waterproof layer non-woven E-glass fiber cloth can be used for enhanced carcass. 5, the dosage :1-2kg / m2. Note 1, HB emulsion adhesive prior to use uniform mixing. 2, cement required 425 # or more ordinary portland cement or slag cement; early strength cement should not be used. 3, HB emulsion glue should be stored in a cool place, shelf life of 24 months
