    Waterproof coatings are generally cement waterproof coatings, acrylic waterproof coatings, polyurethane waterproof coatings, its improper construction operation can easily lead to deep defects. Next JinYuJie waterproof to a brief introduction to the types of waterproof paint and construction methods, I hope to help you in the future home decoration.
    types of waterproof coatings and construction methods areFirst, polymers - cement waterproof coatings
    china
    .
    It is a volatile cured coating, mainly divided into two types: Type I, polymer emulsion as the main ingredient, add a small amount of inormeric active powder, cured to form a flexible coating film, can be applied to the water surface for waterproofing layer;, acrylic waterproof coating.
    it is a volatile cured coating, with better weather resistance, suitable for exposed, non-exposed parts and water-resistant construction. Water-milk color acrylic waterproof coatings have both decorative functions, suitable for roofing and wall waterproofing and decoration. Polymers - cement waterproof coatings, water-milk color acrylic waterproof coatings can be in wet (no water) or dry grass surface construction. Film water resistance less than 80% of the water-milk waterproof coating shall not be used in the basement and other long-term water-resistant parts., polyurethane series of coatings.
    it is a reactive curing type coating, coating film comprehensive performance is good, high strength, large elongation, elasticity, bonding sealing performance is good. Single-group polyurethane coatings rely on the absorption of air and grass-roots moisture and catalyst action curing, can be in the wet or dry grass surface construction; JinYuJie waterproof remind you that the application of polyurethane waterproof coating must pay attention to the choice of low toxic or non-toxic solvents and strictly limit the amount of dosing, reduce the pollution of the atmospheric environment and the impact on personal safety polyurethane waterproof coatings should be used in non-exposed waterproof engineering., cement-based osmosis crystalline waterproof coating.
    it is a rigid waterproof coating material consisting of silicate cement or ordinary silicate cement, quartz sand, etc., which is composed of human active chemicals. The active chemical substances contained in the material are used as carriers to penetrate the concrete interior. In concrete, a vine-like crystal insoluble in water is formed, filling the pores to make the concrete dense and waterproof. This type of coating can be used for water-resistant surface and back-water waterproof construction, suitable for wet substing construction.
    the construction of waterproof coatingsFirst, the coating film to produce pores or bubbles:
    by the mixing method and stirring time is not well mastered caused, should adjust the stirring speed, stirring time to 2 -5min as appropriate., pay attention to the grass-roots treatment:
    grass-roots must be flat, solid, clean, no sand or dust, the grass-roots pore coating to fill the dense.3. Polyurethane waterproof coating in the membrane reaction process to produce CO gas,
    each coating is too thick and other reasons, can make the coating film to produce pores or bubbles, forming a weak part of leakage. Therefore, the thickness of the coating should be strictly controlled during construction.
