Coating technology: what are the precautions for the construction of exterior wall coating

Core tip: during the construction of exterior wall coating, different weather and seasons will have a certain impact If the treatment continues, it will have a great impact on the project Not only that, unreasonable exterior wall coating construction will not affect the quality of the whole project Therefore, today we need to understand the construction conditions of exterior wall coating and exterior wall coating Please refer to the following for details: Precautions for exterior wall coating construction: 1 Before use, we should check the label of the coating, mix it carefully and evenly, and cover it tightly after use 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 House News: exterior wall When coating construction is in progress, different weather and seasons will have a certain impact If the treatment is continuous, it will bring great impact on the project Not only that, unreasonable construction of exterior wall coating will not affect the quality of the whole project Therefore, today we need to understand the conditions of construction of exterior wall coating and the precautions for construction of exterior wall coating Please refer to the following for details: precautions for construction of exterior wall coating: 1 Before use, we should check the label of the coating, mix it carefully and evenly, and cover the cover tightly after use 2 The storage and construction of the coating shall meet the air temperature conditions specified in the product specification, which shall generally be above 5 ℃ If the coating is frozen during storage and transportation, it shall be placed in a room with higher temperature to thaw naturally, and it shall not be baked with fire The unfrozen coating can be used only after it is confirmed that there is no qualitative change 3 The color matching of the coating should be completed by the manufacturer or distributor to ensure the consistency of the color of the batch of coating If color mixing is required at the construction site, the color paste provided by the manufacturer or designated brand and place of origin must be used According to the use requirements and proportion, the color paste shall be allocated by special personnel 4 Attention shall be paid to the protection of finished products of coating engineering to prevent human pollution caused by cross operation If the constructed wall is polluted by dirt, it can be lightly scrubbed with a clean wet cloth If the pollution is serious, it should be repainted 5 Pay attention to weather forecast before construction to avoid operation before rain and snow 6 The brushing tools shall be cleaned and kept properly after use Construction preparation and construction conditions of exterior wall coating: 1 Preliminary construction preparation: for the construction process of exterior wall coating, first of all, the preparation work shall be done well, first of all, the pH value of the base course shall be below 9, and the humidity shall be less than 10%; the surface shall be flat, the internal and external corners and corner lines shall be dense, and the outline shall be clear; the wall surface shall be free of water seepage, cracks, hollowing, blistering holes and other structural problems No powdered loose matter, no oil, grease and other adherents 2 Construction conditions: as the exterior wall coating is water-based, the conditions for the construction process of the exterior wall coating are relatively harsh The construction and maintenance temperature is higher than 5 ℃, and the environmental humidity is not higher than 85% In order to ensure good film-forming Low temperature will lead to the pulverization and cracking of the paint film High ambient humidity will usually make the paint film dry for a long time, and eventually lead to poor film formation Weather factors must be considered in the construction of exterior wall Before painting, it does not rain for 12 hours to ensure the base is dry After painting, it cannot rain for 24 hours to prevent the paint film from being damaged by rain Construction process of exterior wall coating: 1 Repair the exterior wall → clean up → fill the putty, apply the putty locally → polish the wall surface → paste the fiberglass cloth → fully apply the putty → Polish again → primer construction → first finishing coat construction → second finishing coat construction , the above is the general process of exterior wall coating construction technology, which can be used as a reference for friends 2 After the completion of exterior wall coating construction process, it is required that the exterior wall coating shall not have the following phenomena: first, there shall be no leakage of coating, penetration, peeling, peeling, anti alkali, color biting and other phenomena; at the same time, the overall color shall be the same, the density shall be uniform, and finally, there shall be no sagging, pimple, brush pattern and pollution of doors and windows Therefore, the doors and windows should be protected before painting The doors and windows should be covered with plastic film or newspaper In the construction of exterior wall coating, we should pay attention to the above problems In addition, before the construction, we should look at the weather surface, and then consider not to construct In addition, after the construction of exterior wall coating, we should also do a series of checks to avoid some mistakes in details 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,
