Paint knowledge, the inadequacy of real stone paint technology and improvement methods

Core tip: cracks sometimes appear in the internal and external corners during the spraying process of the real stone paint Because the internal and external corners are the intersection of two surfaces *, if the real stone paint is sprayed, there will be two different directions of tension acting on the coating at the internal and external corners at the same time during the drying process, which is easy to crack On site solution: if the internal and external corners of the cracks are found, spray again with a thin spray gun, and spray again every half an hour until the cracks are covered; For the internal and external corners of new spraying, special attention shall be paid not to spray thick at one time Thin spray multi-layer method shall be adopted, i.e spray again after the surface is dry The distance of spray gun shall be far, the movement speed shall be fast, and it is not allowed to spray vertically at the internal and external corners Only scattering, i.e spraying, can be adopted Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Home of paint news: Cracks in internal and external corners during the spraying process of real stone paint, sometimes cracks appear in the internal and external corners, because the internal and external corners are the intersection of two sides *, if the real stone paint is sprayed, there will be two different directions of tension in the drying process at the same time acting on the coating at the internal and external corners, which is easy to crack On site solution: if the internal and external corners of the cracks are found, spray again with a thin spray gun, and spray again every half an hour until the cracks are covered; For the internal and external corners of new spraying, special attention shall be paid not to spray thick at one time Thin spray multi-layer method shall be adopted, i.e spray again after the surface is dry The distance of spray gun shall be far, the movement speed shall be fast, and it is not allowed to spray vertically at the internal and external corners Only scattering, i.e spray two surfaces, and let the edge of spray flower sweep into the internal and external corners The main reason for plane cracks may be that the weather temperature difference is large and suddenly becomes cold, resulting in different drying speed of the inner and outer layers, and cracks are formed when the surface is dry and the inner layer is not dry The on-site solution is to use a small nozzle spray gun, spray thin layers, try to control the drying speed of each layer, and the spraying distance is a little longer Cracks appear in the process of film formation When spraying, the coverage is not uniform or too thick Cracks appear on the surface of the coating after film formation, or even after several weeks This situation should be analyzed in detail In addition to the spraying method, the formula should be changed if necessary, and trial production should be carried out again 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,
