Common knowledge of coating: Sixteen procedures and acceptance standards for construction coating

Key tips: Sixteen procedures and acceptance standards for coating construction: 1 Check and clean the base course to see whether there is dust, oil stain and impurity on the surface of the base course, whether the base course is solid and firm, whether the base course has cracks, whether it is flat, vertical and dry 2 The base course is the guarantee for the beauty and durability of the coating, and the cracking of putty layer and coating layer caused by the base course factors (such as cement mortar or wall cracking) is a common disease It is a general method to use bandage to deal with the cracks in the base course If inferior glue is used for the original white covered wall, alkali resistant primer shall be applied for reinforcement, and the wall with pulverization shall be removed 3, wood 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: 16 procedures and acceptance standards for coating construction: 1 Check and clean the base course to see whether there is dust, oil stain and impurity on the surface, whether the base course is solid and firm, whether the base course has cracks, whether it is flat, vertical and dry 2 The base course is the guarantee for the beauty and durability of the coating, and the cracking of putty layer and coating layer caused by the base course factors (such as cement mortar or wall cracking) is a common disease It is a general method to use bandage to deal with the cracks in the base course If inferior glue is used for the original white covered wall surface, alkali resistant primer shall be applied for reinforcement, and if the wall surface is powdered, it shall be removed 3 The wood plate shall be closed to avoid the deformation and color penetration of the plate surface 4 The key point of patching is to apply bandage to ensure the smoothness and firmness of the interface around patching Sticking two layers of bandages can reduce the cracks in the coating layer 5 If the flatness of local puttying base course is not enough, puttying and leveling shall be applied to the local uneven parts first; however, if the flatness deviation of the base course exceeds 8mm, it is not allowed to use the putty to adjust the thickness, and cement mortar shall be used to treat the leveling 6 Grind and polish the putty, Ensure that the base course is roughly flat 7 The first layer of full puttying construction shall not be exposed, missed or left with joint marks 8 The second layer of full puttying puttying is generally applied twice, and the time interval for each layer of puttying shall not be too long The thickness of puttying shall be 1-3mm 9 The internal and external corners * shall be straight to ensure that the internal and external corners are in a straight line 10 For the third full puttying, when there is a high requirement for the flatness of the wall, the puttying can be increased once, but the polishing thickness of the last puttying should not be less than 0.8mm.11 The requirements for the flatness of the puttying layer are high for the fine grinding and leveling coating, which should be polished and leveled, and the puttying layer should not be too hard, so as to prevent the puttying layer from being too smooth and free of fine sand marks after polishing, It is not conducive to the adhesion of the coating to the putty layer 12 The function of the first primer is to resist alkali sealing, reinforce the putty, and cover with fine sand marks Therefore, the first coating layer should be as full as possible 13 During the polishing process of the putty layer, the putty layer breaks When the sand hole is filled, the putty should be filled after the first coating is finished 14 After the putty is polished and filled, the traces should be polished, Avoid affecting the integrity of the coating 15 In order to ensure the finishing effect of the surface coating, the total thickness of the bottom coating should be 30mm, and the bottom coating should not be greedy for labor and material saving, but only the first one 16 The leveling of the bottom coating is not enough, and it should be well polished when the top coating is polished to ensure the smooth effect of the surface coating 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,
