Extension of JS flexible composite waterproof coating I. Overview Extension of JS flexible composite waterproof coating is a composite of polymer emulsion and cement based inorganic powder made of two-component waterproof mortar. The waterproof mortar is being recognized as a new waterproof material water sector, the Ministry of Construction, the State Bureau of Building Materials Products to focus on. Second, product characteristics 1, the product can be applied directly in the wet base surface. 2, the product has excellent film-forming water resistance, weatherability. 3, set waterproof and adhesive material in one, or mosaic tiling and other protective layer directly on the waterproof layer. 4, does not contain any organic solvents, non-toxic and pollution-free, is a green product. 5, the product is suitable for slope base, toilet and bathroom, swimming pool and other parts. Third, the product type two-component. ?

All parts should be securely installed nodes, joints tight, closed head smooth. 2, the construction is completed primary treatment method for building stronger layer processing node portion, the reinforcement layer can be used paint brush or cloth reinforced mesh lining. After the node enhance the process, brushing primer. When configuring a primer, according to A: B: water = 1: 1.2: 1 ratio of mixing, stirring evenly. Use the scraper to scrape the surface of the base primer evenly coated after careful examination, the base surface may not appear open at the end phenomenon. A large area of ??the rear primer paint to dry construction, coatings in accordance with the ratio Stir, knife channel number can be executed according to the design requirements, we recommend at least three. Scratch conducted every construction in the same direction, but on a vertical work with. Scratch every interval to eight hours, with the coating to dry prevail. If you need to make rigid waterproof layer protection layer, must complete two days after the last film in the construction, such as poor ventilation or winter construction, the time should be extended. V. Note the following 1,0 ℃ or rain not construction. 2, each film dosage should not exceed 0.8kg / m, as every scratch is too thick, curing speed internal inconsistencies, easy to crack, the impact of a membranous most. 3, after the coating mix is ??recommended once exhausted, turned unmixed paint, to be sealed, the cured coating can not be diluted again. 4, used tools, utensils should be promptly clean water. VI, packaging, transport and storage 1, JS liquid material plastic bucket sealed packaging, powder with plastic bags sealed packaging. 2, Specifications: liquid feed: 20kg / barrel, 50kg / barrel, powder: 25kg / bags, 50kg / bag. 2, the liquid material should be stored in a cool place above 5 ℃, insulation measures must be taken when the temperature is below 0 ℃ winter, the powder should be kept in a dry place. During transportation to prevent the sun and rain, prevent collisions, maintain packaging intact. Under these conditions, JS waterproof mortar shelf life of 12 months.
