The alkali closed primer has a strong penetration of ultrafine particles, a strong anti-alkaline, closed, water resistance and adhesion, can enhance the substrate strength and coating adhesion to the substrate, so that the film and the wall body the perfect combination to save the amount of topcoat to a certain extent, at the same time comprehensive protection film from the erosion of the wall of an alkaline substance, greatly increasing the life of the paint film. 

 The alkali closed primer scope of application: 
 Concrete, cement mortar, wood, terrazzo, brick walls and rough fiberboard and other substrate surface for sealing primer. 

 Alkali closed primer features: 
 Special and excellent alkali resistance, to prevent efflorescence wall, with excellent adhesion to the substrate, good adhesion on the finish; 
 Small particles of high molecular weight copolymers with superior penetration, the effective closure of the reinforcement wall; 
 Transparent film, save topcoat usage and improve the fullness of finish; 
 Brush, roller, construction and excellent performance; 
 Pure green products, nontoxic, green environmental protection. 

 Alkali closed primer coating rate: 
 Theory brushing area :8-10 m2 / kg, and the actual construction of the surface roughness and the dilution ratio, the consumption of paint are different. 

 The alkali closed primer construction Description: 
 The wall must be clean, dry, smooth, solid, moisture content of less than 10%. 
 Time brushing the alkali sealing primer drying time of not less than two hours. 
 Surface holes, cracks, need to use putty pretreatment. 
 Construction of the temperature of not less than 5 degrees.
