Coating process: spraying construction process of real stone paint

Core tips: 1 Construction preparation of real stone paint: (1) Spraying construction materials of real stone paint: primer, real stone paint, finish (2) Equipment and tools for stone paint spraying: ① Base cleaning tools: scraper, wire brush, hammer, drill, broom, etc ② Spraying (plastering) machines and tools: air compressor (0.8-1.2mpa), rigid plastic air pipe (outer diameter: 6mm), portable bucket gun, colorful gun, steel spatula, No.2 brush, hand-held toothless saw ③ Surface treatment tools: sandpaper (40, 60 mesh), clean cloth ④ Auxiliary tools: baffle (0.3 & time 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 Paint Home News: 1 Real stone paint construction preparation: (1) real stone paint spraying construction materials: primer, real stone paint, finish (2) Real stone paint spraying construction equipment and tools: ① base cleaning tools: scraper, wire brush, hammer, drill, broom, etc ②

saw ③ Surface treatment tools: sandpaper (40, 60 mesh), clean cloth ④ Auxiliary tools: baffle (0.3 × 1.0m), bucket, spoon, etc (3) Construction preparation of real stone paint: ① the scaffold shall be double row type and placed less than 200mm away from the wall, and the small cross bar shall not touch the wall, or the basket scaffold shall be used, but the contact with the wall must be handled properly ② The moisture content of the base course is required to be less than 8% ③ It is required that the base course shall be flat and clean, the surface of the base course shall be covered with dirt, which shall be removed by scraper and wire brush, and the uneven parts shall be treated and leveled first ④ The surface of the base course shall be repaired with polymer cement putty for the lack of edges, holes, cracks and pockmarks The commonly used putty is made of 707 glue and cement, the ratio of which is 107 glue: Cement = 20:100, with appropriate amount of water added ⑤ For the original facing of wall trimming or other foundation surface, the adhesion shall be tested and confirmed If the adhesion is poor, it must be removed Otherwise, it must be treated to meet the requirements 2 Construction process of real stone paint: clean the base course → make grid lines → spray primer → apply natural real stone paint once → spray natural real stone paint → Polish → clean floating dust → spray top coat → spray antifouling paint (1) the surface is flat, clean and free of dirt (2) Make dividing strip, snap ink line, and use toothless saw to make dividing groove with width of 20mm and depth of 15-20mm (3) Spray primer with a colorful spray gun, generally from left to right, then from right to left The spraying distance is about 0.4m, the spraying thickness should be less than 1mm, the spraying pressure is 0.4-0.6mpa, the diameter of the spray gun should be adjusted to 2-3mm, and the drying time is about 60 minutes Roll coating and brush coating can also be used (4) Natural stone paint spraying (or daubing) ① one touch spraying method: first, use a steel spatula to scrape a thin layer of natural stone paint, and the second time use a stone paint spray gun to spray evenly, the total thickness of the two times is 2-3mm, or according to the design requirements, the interval time should be more than 30 minutes ② For the spraying construction method, the indoor works can be finished in one time, and for the outdoor works, the spraying shall be completed in two times The total thickness of two times is 2-3mm, or according to the design requirements ③ For natural stone paint with light color, the construction method of one coat and two sprays can be adopted according to the actual situation of the project and the premise of ensuring no leakage of the bottom The thickness depends on the actual situation of the project or according to the design requirements ④ The floating point size can be adjusted and controlled by the "gun plug" During the spraying process, the center line of the spray gun mouth shall always be vertical to the spray surface, and the distance between the spray gun bucket and the spray surface shall be 0.3-0.5m (5) Grinding: after the natural stone paint is completely dried (it can be dried in 24 hours under normal environmental conditions), polish the surface with sandpaper to be relatively smooth, and then wipe off the floating dust with a clean and damp cloth (6) The finishing coat shall be painted twice ① the finishing coat shall be painted twice with a colorful spray gun, with an interval of 60 minutes The specific method is the same as that of the primer The thickness shall be less than 1mm ② If one coat of waterproof protective paint and one coat of antifouling paint are applied, the interval time is 60 minutes and the total thickness is less than 1mm 3 Construction precautions: (1) the construction of natural stone paint must be carried out in the final stage of the decoration project to avoid contamination or damage of the coating (2) In case of heavy rain during spraying, the constructed part must be covered to prevent rain water flushing (3) After natural stone paint is polished and cleaned, waterproof protective film paint or antifouling paint shall be sprayed in time to prevent accidents (4) Under 5 ℃, it is not suitable for construction in windy or rainy days (5) When multiple spray guns are used to spray the same spray surface at the same time, the "gun plug" of the same model shall be selected Home of coatings is specialized in coatings, diatom mud, paint
