    China Paint Online News Information: What are
    the construction of closed primers for real stone paint? The closed primer used in the construction of real stone paint is made of fine grain diameter polymer and a variety of additives, the product penetration is strong, can close the pores of the cement wall, play the role of preventing the return of alkali. In addition, the closed primer can also enhance the strength of the cement base, increase the paint to the grass adhesion. Therefore, to ensure the quality of real stone paint construction, the use of closed primer is very important. Since the closed primer is transparent, care should be taken to prevent leakage during construction, and if leakage occurs, the coating may be flowered due to pan-alkali.

    The role of closed primer
    (1) closed substrate, penetrate into the internal structure of the substrate, block the capillary holes in the substrate, reduce the number of open holes in the substrate, increase the number of closed holes, inhibit the penetration of paint moisture, so that penetration becomes uniform, so that the substrate to the upper coating absorption becomes uniform.
    (2) closed primer can prevent moisture, anti-alkali isolation, the base of the alkali can be effectively isolated, to prevent the oozing of alkali damage to the coating.
    (3) strengthens the loose and weak substrate and strengthens the substrate. The requirements of closed primer: closed primer is attached directly to the substrate, which is attached to the medium coating, the surface coating, the role of the upper and lower, a good coating system between the layer and the coating film there is no layer interface, coating construction requirements between each process can be effectively mutual Penetration, the whole coating becomes a whole, closed primer is attached to the substrate on the first membrane, so the quality of closed primer requirements are very high, there is good water resistance, alkali resistance, waterproof isolation saline oozing, there is good adhesion and inter-layer adhesion. Closed primer type and raw material selection: closed primer has solvent and water-based two, solvent-based closed bottom penetration, closed strong, water-based water emulsion and water-soluble. The closed primer of the water emulsion and silicone sol composite provides the closed properties of the combination of solvent type and emulsion. According to the type and condition of the substrate select closed bonding substrate, loose porous substrate selection strong penetration and strong closure can strengthen the substrate substrate, dense and smooth substrate selection of strong bonding properties of the substrate, and require good inter-layer adhesion.

    closed primer features: 1, strong permeability, excellent closed performance, can improve the strength of the substrate. 3, coating alkali-resistant, acid-resistant, water-resistant performance is excellent, and the surface matching good. 4, can brush, roll coating, construction performance excellent construction. Safety requirements: 1 must avoid inhalation of solvent vapor, eyes, skin must not touch this product, 2 construction should maintain adequate ventilation, 3 away from Mars and open fire, packaging if open, should be used up as soon as possible, construction method 1, before construction, the wall must be clean, dry, flat, no loose. 2, uneven place first filled with putty, dry after grinding flat, and remove dust. 3, if the wall has old paint, should be removed clean. 4, brush coating, roller coating, airless spraying 6, construction environment: temperature is not low day 5 degrees C, relative humidity is not greater than 85%7, primer: closed primer 1 layer 8, finish: exterior paint or interior wall latex paint 2-3 layers.
