Coating process: waterproof and moisture-proof coating construction process

Core tips: the construction process of waterproof and moisture-proof coating is as follows: Base surface cleaning → base surface treatment → division of painting area → sufficient wetting of base surface → preparation of slurry → painting → subsequent painting construction → maintenance → acceptance Base treatment: Before applying (rolling) the waterproof and damp proof course, the construction base surface shall be treated: (1) for the plastering surface of the brick wall, the base surface shall be polished and leveled, and the base surface shall be uneven Paint agent, top 10 Chinese wall paint brands Recommended introduction: interior wall paint and exterior wall paint can achieve beautiful, clean and pleasant effects, but the effects in different environments are different, so the color of the paint will be different There are ten brands of Chinese paint, ten brands of global paint, ten brands of Chinese wall paint, and ten brands of Chinese paint, Famous trademark of Chinese paint and coating In private rooms, most of us choose according to our own personality, personal hobbies and living habits The younger generation will choose the interior wall paint with rich colors and bright colors, while the older ones will have some working experience Coating home news: the construction process of waterproof and moisture-proof coating is as follows: base surface cleaning → base surface treatment → division of painting area → sufficient wetting of base surface → preparation of slurry → painting → subsequent painting construction → maintenance → acceptance Base course treatment: before the construction of waterproof and damp proof course coating (rolling), the construction base surface shall be treated: (1) for the plastering surface of brick wall, the base surface shall be polished and leveled, and the uneven part of the base surface shall be filled and leveled before the construction of the next process (2) for the concrete surface layer, the oil stain, rust, sundries, laitance, reinforcement and formwork on the concrete surface shall be completely removed by scraping, chiseling, polishing and other methods, and the concrete base surface shall be cleaned so that the waterproof coating can be closely combined (3) For the floor, the protruding objects and scum on the reinforced concrete floor shall be cleaned up, the surface shall be spread with plain cement slurry and made with 20 thick 1:2.5 cement mortar leveling layer, and then uniformly coated with cement-based permeable crystalline waterproof coating Construction technology of waterproof and moisture-proof coating: (1) special fiber brush is used for painting equipment, and special roller is used for rolling equipment (2) first clean up the oil, rust, sundries, laitance and other pollutants on the base surface, and then clean the construction surface with water (3) level the honeycomb and pitted surface (4) prepare the slurry according to the required mix proportion, apply the first coat, and carry out the second coat construction after the interval of about 4-8 hours (depending on the indoor environmental humidity, press the coating with fingers, and the coating becomes hard without any trace) The corners and special parts of the side wall shall be painted first Precautions for construction of waterproof and moisture-proof coating: wet the construction surface with water before painting, the construction surface shall be damp but not wet, and the water of the base course shall be saturated as much as possible The coating construction can be carried out by brushing or rolling The brushing method is usually applied by hard bristle brush (artificial fiber is preferred), and the roll coating method is applied by special roller The coating (roll) is applied twice The coating is required to be uniform, and the coating (roll) is applied everywhere When applying (rolling) brush, pay attention to the force Brush back and forth in a crisscross way to ensure that the concave and convex parts can be painted evenly After the completion of the first coating, press it gently with fingers without any trace, and the second coating construction can be carried out after 4 hours If it is too dry, spray water first to wet and maintain, and the overlapping width of the layer shall not be less than 100mm 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,
