Coating classification: exterior wall external insulation flexible water-resistant dry powder putty

Core tip: Introduction: At present, with the rapid development of external wall insulation technology in China, it plays an active and important role in promoting the construction energy conservation However, with the development of exterior wall insulation engineering, some common engineering quality problems are exposed Especially in the exterior wall thermal insulation engineering with coating as the facing layer, there are often quality problems such as cracking, foaming and falling off of coating layer, which seriously affect the decoration of the building and the protection of the thermal insulation system Combined with the flexible gradual change characteristics of external wall insulation system, the special flexible water-resistant dry powder putty for external wall insulation must have high bonding strength and crack resistance 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 Introduction: at present, the external wall insulation technology in China is developing rapidly, which plays an active and important role in promoting the construction energy conservation However, with the development of exterior wall insulation engineering, some common engineering quality problems are exposed Especially in the exterior wall thermal insulation engineering with coating as the facing layer, there are often quality problems such as cracking, foaming and falling off of coating layer, which seriously affect the decoration of the building and the protection of the thermal insulation system Combined with the flexible gradual change characteristics of external wall insulation system, the special flexible water-resistant dry powder putty for external wall insulation must have the characteristics of high bonding strength, excellent crack resistance, low water absorption, good air permeability and easy construction Features: ① excellent crack resistance, able to resist micro cracks caused by various stresses; ② especially suitable for leveling on external wall thermal insulation crack resistance mortar or plastering mortar; ③ good air permeability and hydrophobicity; ④ strong adhesion, with two-way affinity to wall and coating; ⑤ non-toxic, odorless, environmental protection products Performance technical group index: Construction: construction method ① after the anti crack protective layer of the external insulation system is accepted and confirmed to be stable, clean and free of hollowing, floating dust, laitance, grease and batik, the flexible putty can be constructed ② According to the putty powder: water ≈ 1:0.3 (weight ratio), pour the accurately weighed mixing water into the clean mixing bucket, start the electric mixer, slowly add the flexible water-resistant putty powder, continue to mix for 3-5 minutes, until it is even and free of caking, stand for 5-10 minutes, mature, and then mix for 2-3 minutes to make the slurry become a uniform paste ③ Apply the putty on the anti crack protective surface with a scraper The thickness of putty application should be 0.5-0.8 mm at a time Generally, two or three times of putty application can be completed depending on the flatness of the base course Note: the putty shall be used as soon as it is stirred The prepared putty shall be used up within 2 hours It is forbidden to add water to the dried putty for further use In case of high temperature in summer, the base course shall be wet first, and the putty application construction shall be started after there is no open water on the surface Storage and transportation: store in a cool and dry place for 12 months 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,
