Paint knowledge | common plastering mortar

Core tip: common plastering mortar is the largest amount of plastering mortar in construction engineering Its main function is to protect the wall and ground from the erosion of wind and rain and harmful impurities, improve the performance of moisture-proof, corrosion-proof and weathering resistance, and increase the durability; at the same time, it can make the surface of the building flat, clean and beautiful Plastering mortar is usually divided into two or three layers for construction The requirements of each layer of mortar are different, so the mortar selected for each layer is also different Generally, the bottom mortar plays the role of bonding the base course, which requires that the mortar should have good workability and high bonding force, so the water retention of the bottom mortar is better, otherwise the water is easily absorbed by the base material and affects the mortar 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: common plastering mortar is the largest amount of plastering mortar used in construction projects Its main function is to protect the wall and ground from the erosion of wind and rain and harmful impurities, improve the performance of moisture-proof, corrosion-proof and weathering resistance, and increase the durability; at the same time, it can make the surface of the building flat, clean and beautiful Plastering mortar is usually divided into two or three layers for construction The requirements of each layer of mortar are different, so the mortar selected for each layer is also different Generally, the bottom mortar plays the role of bonding the base, which requires that the mortar should have good workability and high bonding force, so the water retention of the bottom mortar is better, otherwise the water is easily absorbed by the base material and affects the bonding force of the mortar The rough surface of the base course is good for bonding with mortar Middle plastering is mainly for leveling, sometimes it can be omitted The surface plastering is mainly for the purpose of flatness and beauty, so fine sand is selected For the bottom plastering of brick wall, lime mortar is often used; for the bottom plastering of slatted wall or ceiling, mixed mortar or lime mortar is often used; for the bottom plastering of concrete wall, beam, column, roof, etc., mixed mortar, pocketknife lime slurry or paper reinforced lime slurry is often used Where it is easy to collide or wet, cement mortar shall be used Such as wainscot, skirting board, ground, canopy, windowsill, pool, well, etc., generally 1:2.5 cement mortar is used 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,
