Coating process: acrylic exterior wall coating construction process

Key tips: 1 Construction process: 2、 Construction process (1) Base course inspection ◆ patrol and inspect the wall of each floor carefully, and inform Party A in writing of the problems such as uneven wall, hollowing, uneven internal and external corners, cracks, grid joints, excessive humidity, etc., which need to be solved by the civil engineering party as soon as possible ◆ construction protection The parts not to be painted shall be closed and isolated to avoid pollution (2) Base treatment process ◆ cracks (civil engineering quality problems, assist in handling) A edge Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Home of coatings news: 1 Construction process: 2 Construction process (1) basic level inspection ◆ patrol every wall surface and check carefully Inform Party A in writing of the problems such as uneven wall surface, hollowing, uneven internal and external corners, cracks, grid joints, excessive humidity, etc., which need to be solved by the civil engineering party as soon as possible ◆ construction protection will be closed and isolated to avoid pollution (2) Base surface treatment process ◆ cracks (civil engineering quality problems, help to deal with) a chisel along the cracks or cut the V-groove with a depth of 2-3mm B clean up the dust, brush the sealing primer (improve the adhesion of putty) C fill the cracks with putty, no cracks, good flatness ◆ the surface of embedded parts shall be derusted and polished B brush with antirust primer ◆ honeycomb, pitted surface and holes (civil engineering quality problems, assist in handling) a 901 glue and cement shall be added in proportion of 1:3 to repair the honeycomb and pitted surface B after drying, polish it to be flat and smooth ◆ the residual slurry and the attached garbage on the wall shall be removed, and the wall shall be shoveled once with a blade, especially the corner parts of the window frame shall be cleaned until there is no attachment on the wall ◆ the formwork joint shall be polished smoothly with an angle grinder, and the transition shall be smooth ◆ cut a 2-3mm deep V-groove along the joint of the frame and brick wall, and fill it with putty to prevent cracking (3) Apply putty: level the external wall putty for three times ◆ when the first putty is fully applied, the thickness shall be controlled below 1-2mm ◆ level the internal and external corners of the base surface ◆ after the putty is dry, remove the scraper marks and burrs on the putty surface with abrasive cloth, and then apply the putty for the second time Check the putty layer on the base surface, repair the damaged part, and measure the flatness with a straight guiding rule, which shall meet the national acceptance standard Sanding: ◆ attention shall be paid to grinding joints and edges to make them smooth and excessive; ◆ grinding shall be focused on the corners and joints of the wall where it is not easy to grind; ◆ cleaning the floating powder and dust on the wall to facilitate the next process; (4) painting primer: one full spraying of oily sealing primer A before applying the primer, it shall be confirmed that: the wall humidity is not more than 8%; ◆ the surface dust has been cleaned; ◆ to prevent cross contamination; B before applying the primer, it shall be protected to prevent the contamination of finished products and semi-finished products; when applying the primer, it shall be carried out according to the construction method of first corner, edge and then large surface During rolling coating, obvious joints shall be prevented; foreign matters stuck on the wall shall be cleaned in time C set up full-time personnel for inspection The primer shall not be missed or sagged, and obvious joints and uneven roll coating are not allowed D the next construction can be carried out after the drying time is 24 hours E putty repair ◆ after the primer is dry, some sand holes, defects and small cracks in the wall body will be seen, and the putty will be used for repair ◆ after the putty to be repaired is dry, sand grinding and re patching the primer; (5) painting the top coat: spraying the top coat twice ◆ mix with professional diluent according to the proportion required in the product manual, and keep it still for 15 minutes according to the site climate, so that the paint can react completely During construction, the air temperature shall be above 5 ℃, and it is strictly prohibited to brush the top coat below 5 ℃; ◆ stir evenly with the mixing gun; ◆ the top coat must be rolled on the dry primer or the middle coat; ◆ brush the corners and the parts that are not easy to spray first, and then carry out the top coat construction from the top to the bottom The construction of the parts that are easy to be dirty and stained shall be carried out later, such as windowsill and skirting line The second finishing coat must be constructed after the first finishing coat is completely dry ◆ the construction of two color finishing coats shall prevent mutual pollution The lighter paint shall be painted first, and the darker paint shall be painted later, so as to cover the light paint within the overcolor line ◆ the coating surface must be uniform, without bottom leakage, pinholes, sagging, wrinkles and other undesirable phenomena (6) Construction cleaning and burying ① machine cleaning ◆ after each construction, the roller brush shall be cleaned, dried and hung at the designated position ◆ other tools and equipment, such as wires, lights, ladders and so on, shall be recovered in time and shall not be placed at will ◆ mechanical equipment shall be cleaned and repaired in time ②construction cleaning After the completion of construction, keep the construction site clean and tidy The contaminated non construction parts, equipment and equipment shall be cleaned without damage 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,
