Waterproof use method

1.？ The surface of the substrate must be sufficiently wet to saturation (but free of water) and must be firm, clean and flat. Uneven place can be leveled with cement mortar and 1-2 times medium sand.

2.？ Ingredients: retarding waterproofing should be selected for waterproof surface construction. Mix the materials according to the ratio of powder: water = 1: 0.30 ~ 0.35 to form a uniform putty (excluding raw meal powder or particles). Manual stirring should not exceed 5 kg at a time, otherwise it should be stirred with a blender.

3.？ Feeding: feeding in the order of "plastering method" and making two layers. Wipe the first layer of material on the board with a trowel or scraper: after the coating hardens, spray it wet (but don't use water), and then coat the second layer of material. The feeding interval of each layer is about 1 hour. Scrape back and forth more when feeding to make the coating dense, and pay attention to lap joint at the same time. The material of each layer is about 1.2kg/ m2, the total material is about 2.4kg/ m2, and the coating thickness is about1.5mm.

4.？ Moisturizing and curing. After the coating is hardened, it should be cured immediately to ensure that the coating is wet and prevent pulverization. Care should be taken to avoid damaging the coating during the first curing. * * * Cure for 2-3 days by spraying water, covering with wet substance and coating with curing liquid. In particularly humid places (such as the basement with stagnant water). ) or waterproof coating after hardening, immediately put a protective layer or block on it, which can save moisture curing.

Second, the seepage surface construction

1.？ The surface treatment of the substrate should be wet, firm, clean and smooth. Uneven places should be leveled with medium sand which is twice the weight of water leakage. If the seepage of foundation surface is serious, a diversion hole should be drilled at a proper position to concentrate the leaked water.

2.？ Ingredients: the matrix with serious leakage and water seepage should be made into quick-setting, impervious and evenly stirred (according to the required time), and the powder should be stirred into a uniform putty shape according to the ratio of powder: water = 1:0.3 ~ 0.35 (excluding raw powder or particles). Don't use too many ingredients at a time, so as to avoid solidification and waste.

3.？ Feeding shall be carried out in the order of "plastering method", * * two or three times. Specific practice: after drying the surface of the base with a dry cloth, quickly wipe the first layer of material with a trowel. If there is water leakage, leave it alone: after the coating hardens, dry the second layer of material on the surface; if there is still more water leakage, apply the third layer of material in the same way. If there is only local water leakage, add another layer at the leaking place until there is no water leakage.

Rub it back and forth several times with a little force to make the coating dense, and pay attention to lap joint at the same time. The material of each layer is about 1.2kg/ m2, the total material consumption of two-layer method is about 2.4kg/ m2, and that of three-layer method is about 3.6 kg/ m2. The coating thickness of two-layer method is about 1.5mm, and that of three-layer method is about 2.2 mm.
