Coating knowledge: coating decoration construction skills -- renovation construction technology of old buildings

Core tip: [news] in the renovation and coating project of the old building, first of all, it is necessary to find out what materials are used to decorate the old wall surface, so as to make the renovated wall surface glow In the past, the wall decoration materials were basically ceramic tiles or ordinary coatings For the renovation of these two types of walls, here are some introductions, hoping to be helpful for the reference of peers ● renovation of old tiles With the increasing use of architectural coatings, many old mosaics and facing tiles are not suitable for the needs of modern cities If they are removed completely, the walls are plastered again, and then the coatings are applied again, it will bring too much work and time-consuming 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 Paint Home News: [news] in the renovation and coating project of the old building, first of all, it is necessary to find out what materials are used to decorate the old wall surface, so as to make the renovated wall surface glow In the past, the wall decoration materials were basically ceramic tiles or ordinary coatings For the renovation of these two types of walls, here are some introductions, hoping to be helpful for the reference of peers ● the renovation of old ceramic tiles with the increasing use of architectural coatings, many of the old mosaics and facing tiles are not suitable for the needs of modern cities, such as removing all of them, re plastering and re coating the walls, which will bring problems such as too much work, time and money, environmental pollution, disturbance to the residents, etc As a result, there are some engineering cases of coating and facing construction directly on the old mosaic and tile facing Although the methods of replacing the old mosaic and ceramic tile with paint finish are different, they should be generally treated as follows: 1 The floating soil on the mosaic and ceramic tile surfaces should be cleaned and washed with high-pressure water; 2 The damaged parts should be repaired and leveled first; 3 The ceramic tile surfaces should be polished with electric grinding wheel to increase the roughness; 4 Use special adhesive or new elastic putty on the surface of ceramic tile to scrape the seam of ceramic tile, and then scrape the seam several times If necessary, renovate the putty by adding alkali resistant glass fiber mesh composite ceramic tile according to the bonding force between the ceramic tile and the base, and apply it on the old ceramic tile surface; 5 Carry out the separation joint treatment according to the construction requirements, and at the same time, directly apply or roughen the above materials on the wall surface; 6 After the above materials are dried, apply 1-2 layers of flexible water-resistant putty to level the wall surface After the leveling layer is dried, it shall be painted with latex coating, oil coating, fluorocarbon metal paint and other processes according to the design requirements ● renovation and cleaning of ordinary wall surface: use a blade to remove the loose base of the wall surface If the blade can not be removed, you can use a small hammer to tap gently If there is no sound of hollowing, and the place that is still not loose after tapping can retain the original base Clean the wall: clean the floating dust and oil on the surface thoroughly with detergent or alkali solution, and then wash thoroughly with high-pressure water gun to remove the powdered coating Repair the wall: repair the local damaged parts with the flexible waterproof putty on the outer wall, and then level the whole wall If necessary, the putty layer can be watered for necessary maintenance Application of sealing primer: after the alkalinity of the putty layer is less than 10, the sealing primer shall be applied once Excessive mixing of water with the sealing primer is prohibited and leakage is prevented Paint the exterior wall finish: after the sealing primer is completely dry, paint the exterior wall finish twice It is forbidden to mix too much water during coating application, especially for dark paint, too much water may cause such undesirable phenomena as floating color and blooming Paint house focuses on the news and information of coating, diatom mud, paint coating, coating technology, fireproof coating, coating, diatom mud, paint coating, coating technology, decoration knowledge and decoration effect map of fireproof coating,
