Coating process: polyurethane waterproof coating construction process

Core tips: construction procedure: clean the base course → brush the base treatment agent → brush the additional layer waterproof coating → brush the first coating → brush the second coating → brush the third coating → the first water storage test → dilute sand → quality acceptance → protective layer construction → the second water storage test Key points of operation: 1 Clean the base course: clean the base course; make sure the base course has accurate slope making, smooth drainage, flat and solid surface Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Paint Home News: construction procedures: clean the base course → brush the base treatment agent → brush the additional layer of waterproof coating → brush the first coating → brush the second coating → brush the third coating → the first water storage test → dilute sand → quality acceptance → protective layer construction → the second water storage test Key points of operation: 1 Cleaning the base course: clean the base course; the base course shall be accurate in slope making, smooth in drainage, flat and solid in surface, free from dust, sand, shell and cracking Before applying the base treatment agent, the base surface shall be dry 2 Brush the base treatment agent: mix the polyurethane according to the specified proportion and add the appropriate diluent to mix evenly Brush the internal and external corners and the root of the pipe evenly once, and then brush on a large area The material consumption is about 0.2kg/m2 Dry for more than 4 hours after painting before the next process construction 3 Application of additional reinforcement layer waterproof coating: in the weak parts of floor drain, pipe root, internal and external corners, entrances and exits, which are prone to water leakage, polyurethane waterproof coating shall be applied and scraped evenly once for additional reinforcement layer treatment According to the design requirements, the detailed structure can also be treated as additional reinforcement layer with carcass reinforcement material The width of the matrix reinforcement material is 300-500mm, and the lap joint is 100mm During the construction, it is laid flat and scraped with polyurethane waterproof coating 4 Apply and scrape the first coating: prepare the polyurethane waterproof coating correctly and mix it evenly, and apply and scrape it evenly with rubber scraper or brush The thickness shall be consistent during operation, and the material consumption shall be 0.5-0.8kg/m2 5 Apply and scrape the second coating: after the first coating is cured and dried, apply and scrape the second coating according to the method of the first coating The direction of coating scraping shall be perpendicular to the first time, and the material consumption shall be the same as the first time 6 Coating and scraping for the third time: after the coating film of the second time solidifies and dries, the coating shall be applied and scraping for the third time according to the method of the first time The direction of coating scraping shall be perpendicular to the second time, and the material consumption shall be 0.4-0.5kg/m2 7 First water storage test: water storage test can be carried out after the second coating film is cured and dried It is qualified if no leakage is observed after 24 hours of water storage test 8 Facing layer construction: after the water storage test of the coating waterproof layer is no leakage and the quality inspection is qualified, the cement mortar can be plastered and the facing layers such as ceramic tiles and anti-skid floor tiles can be pasted Attention shall be paid to the protection of finished products during construction, and the waterproof layer shall not be damaged 9 Second water storage test: after the completion of the decoration works, the second water storage test shall be conducted before the completion of the works to check whether the waterproof layer is damaged by hydropower or other decoration works after the completion of the works After the second water storage test is qualified, the construction of waterproof works is completed 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,
