Coating process: which processes and specific operations should be included in the base treatment

Core tip: basic treatment mainly includes the following processes: (1) There is a great relationship between the condition of the base course and the performance of the coating after construction, so it is very important to carry out a comprehensive inspection of the base course before the coating decoration of the building There are many kinds of building coatings You can choose appropriate building coatings according to the conditions of the base, or check whether the base meets the construction requirements according to the selected coatings Generally, the surface conditions such as strength, flatness, pH and cleanliness shall be inspected (2) Cleaning of base course Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Coating home news: the base treatment mainly includes the following processes: (1) the base inspection of the condition of the base has a great relationship with the performance of the coating after construction, so it is very important to carry out a comprehensive inspection of the base before building coating decoration There are many kinds of building coatings You can choose appropriate building coatings according to the conditions of the base, or check whether the base meets the construction requirements according to the selected coatings Generally, the surface conditions such as strength, flatness, pH and cleanliness shall be inspected (2) The purpose of cleaning the base course is to remove the adherents on the surface of the base course and make the base course clean without affecting the adhesion of the coating to the base course There are mechanical and chemical methods for base cleaning In case of hollowing and pulverization of the base course, mechanical chiseling and steel wire brush shall be used to remove floating dust, etc.; the oil, film remover, sealing material and other adherents on the base course can be removed with organic solvent or chemical detergent (3) After the base cleaning work is completed, the defects of the base (such as cracks and cavities in the base) shall be repaired in time According to the specific situation of the defects, appropriate materials and methods shall be used to repair, so as to create a good base for the external wall coating project ① For the treatment of peeling of the old wall coating base, steel wire brush off the peeling coating surface, brush the interface agent, and carry out the coating construction again ② For the treatment of the cracks in the base course of the old wall coating, V-groove shall be opened, alkali resistant glass fiber mesh cloth shall be hung, cement mortar shall be plastered, flexible putty shall be applied, and coating construction shall be carried out ③ For the treatment of hollowing of the old wall coating base, the marble machine cut the hollowing wall, thin and multiple times of cement mortar plastering to reach the height of the original wall, brush the interface agent, and then carry out the coating construction 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,
