    Features
    1, water-based paint, non-toxic harmless, pollution-free green products, is a national key recommendation of one of the materials can be used for drinking water projects;
    2, can be wet or dry in a variety of materials directly on the base surface construction, bonding firm;
    3, the coating has a strong tensile strength, water resistance, good weather resistance;
    4, cold construction, easy to operate, grass-roots water content is not restricted, can shorten the duration, color adjustable, with a dual function of waterproof decoration;
    5, the base surface without water can be built in wet base surface construction.
     
    The scope of application
    Type I products (weight ratio of liquid powder = 1: 1) is mainly used for non-exposed roofing, bathroom, bathroom and external walls of the waterproof, anti-seepage and moisture-proof non-long-term flooding under the building waterproofing works; 重庆体彩gineering and tunnel, hole and other coatings waterproof, used in wet or dry concrete, metal, plastic, porcelain, insulation layer and other base surface, with good adhesion.
    Type II products (weight ratio of liquid powder = 1: 2) for long-term flooding environment under the building waterproofing works and moisture, maintenance works for long-term underground waterproofing site.
     
    Packaging transport storage
    Transport should prevent rain, exposure, by freezing, to avoid extrusion, collision, keep the packaging intact;
    Products used in dry, ventilated, cool place storage, liquid component storage temperature is not low 5 ℃;

    Construction technology
    Construction follow the "first facade, after the plane" in the order, the construction process is as follows.
    Basic treatment → additional layer treatment → first brushing → second brushing → third brushing → protective layer and decorative layer construction → quality inspection and closed water test
    Base preparation
    Treatment of grass-roots surface smooth, solid, no sharp angle, dust and water, and according to the design requirements of the waterproof node to do. The oil is cleared and the corners are flat.
    Mixing method: the first liquid and water into the mixing bucket, portable electric stirrer stirring constantly into the powder slowly, add at least 5 minutes, thoroughly stirring evenly, was slurry without clumps.
    Additional waterproof layer
    According to the design requirements in the groove to fill the sealing material, in the yin and yang angle, root and other details should be more than (2-4 times), underground works should be wrapped with a layer of carcass reinforcement.
    Construction of large surface waterproof layer
    Waterproof coating should be no less than three times, each time interval 8h, winter should be extended. Each coating thickness of 0.3-0.5mm is appropriate, the amount of paint about 0.9kg / ㎡, should not be too thick again, the surface construction to not add water or less water is appropriate to avoid the flow of paint, resulting in the thickness of the facade is not easy to achieve the design thickness , While the accumulation of yin and yang angle is too thick, resulting in cracks. When adding carcass reinforcement material, the carcass should be paved, no wrinkles, lap less than 100mm, the first brushing the application of paint, paved after the above brush again paint.
    Coating waterproof layer to complete the experience after passing, should be designed to protect the isolation layer construction.
     
    Precautions
    Polymeric cement waterproof coating is strictly prohibited in the rain, fog, five or more windy days of construction, not in the construction environment temperature below 5 ℃ and higher than 35 ℃ or sun exposure when the construction.
    ● paving the carcass reinforcement material, the carcass layer should be fully soaked waterproof coating must not have Lucha and wrinkles.
    ● Coating acceptance should be completed after the timely construction of the protective layer.
    ● According to the progress of the preparation of the number of materials, with a good material should be used within 2 hours.
