All construction coatings have passed ISO9001 Coating home news: (1) construction conditions of organosilicon waterproof coating: 1 Organosilicon waterproof coating must be retested on site, and unqualified materials shall not be constructed 2 The materials must be sealed and stored in a cool and dry place, and it is strictly prohibited to contact with water; 3 Necessary and sufficient construction tools shall be provided, and labor arrangement shall be organized; 4 The base course shall have sufficient strength, be solid, flat and free of sand; 5 The dust, oil dirt, particles and other sundries on the surface of the base course shall be cleaned up; (2) the construction process of organosilicon waterproof coating: Remove the peeling off part → clean the base course → repair the brick joint and peeling off part → brush the first silicone waterproof coating → additional treatment of the details → lay the non-woven fabric → brush the second silicone waterproof coating → brush the third silicone waterproof coating → brush the fourth silicone waterproof coating → waterproof layer acceptance (3) key points of construction of silicone waterproof coating: (1) The peeling off part shall be removed, and the peeling off part shall be removed from the base course, and then the base course shall be cleaned without floating dust, sundries and open water (2) Before repairing the brick joints and peeling off parts in large area, the silicone waterproof coating shall be used to repair the brick joints and peeling off parts (3) A layer of reinforced cloth shall be added to the construction site for additional treatment of details First, apply silicone waterproof coating with rubber scraper or paint brush thickness evenly, and paste reinforced cloth immediately for reinforcement treatment When the reinforced cloth is pasted, it shall be spread and flattened with a paint brush, closely bonded with the lower layer of paint, with a lap width of 100mm, and then painted with one or three layers of paint on the surface to make it reach the thickness required by the design (4) The first coating construction and laying of non-woven fabric: before the first coating, mix the organosilicon waterproof coating evenly, use rubber scraper or paint brush to scrape (brush) on the surface of the base course for a thin coating, and then the first coating construction, with uniform thickness and flat surface After the first coating surface is dry, lay non-woven fabric in time (5) Coating construction for the second time: then, apply the coating for the second time according to the above formula and method The direction of each application shall be perpendicular to the direction of the last application, and the amount of application is still the same as that of the first application (6) The third and fourth coating construction: after the second coating surface is dry, the third and fourth coating construction shall be carried out in the same way The thickness of the final waterproof layer shall reach 1.5mm or the design requirements (7) During the acceptance construction of the waterproof layer, the inspection shall be carried out at the same time of painting, and any defect found shall be repaired in time The on-site constructors and quality inspectors must follow the shift for inspection, and the next coating construction can only be carried out after passing the inspection In particular, it is necessary to pay attention to whether the practices at the intersection of the plane and the facade, the corner and the internal and external corners are correct After the self inspection is qualified, it shall be reported to the supervision party / the construction party for overall acceptance of the waterproof layer After the waterproof layer is completed and dried for 48h, it shall be subject to 24h water storage test, and it is qualified if there is no leakage （4） Finished product protection 1 The flexible waterproof system is relatively fragile, so necessary protection must be carried out to avoid damage 2 Heavy utensils and transportation equipment shall not be consigned on the unprotected waterproof layer 3 During the construction of waterproof layer, the operators shall wear soft soled shoes It is strictly forbidden to wear nail shoes to enter the site to avoid damaging the waterproof layer If the coiled material is damaged, it shall be repaired in time Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
