Really stone paint when construction in yellow loss should how to deal with? 2019 KeBao paint entire network

Really stone paint is one of the most popular of the exterior wall coating of our country at present. In really stone paint application process, due to reasons such as construction and the product itself, often appear some problems, affects the quality of paint film, decorative effect and construction cost, and even affect the durability of buildings and normal use, has a certain universality. Next, KeBao building materials will share with you really stone paint construction yellow fall off in the process of treatment. Yellow really stone paint yellow is mainly due to the really stone paint the quality problem of the emulsion. Some really stone paint manufacturers use bad acrylic emulsion as binder, it will decompose after ultraviolet irradiation and isolated non-ferrous material, eventually lead to yellow. Prevention and control measures: grassroots alkalinity should be strictly controlled. If high alkalinity, can be sealed with alkali resistant paint to prevent alkali precipitation. In strict accordance with the normal construction of quantities, do not cut corners; Really stone paint theory of normal distribution is 3. 5 ~ 5. 5 kg/m. Reasonable control of the thickener cellulose proportion. Coating cracking really stone paint coating cracking is really stone paint coating surface drying after the film, and sometimes even in weeks or longer after drying, paint film surface is big or small crack phenomenon. Really stone paint coating cracking is the main reason of the: cracking at the grass-roots level; One-time spraying quantity is too large, coating is too thick; Basic no divided into pieces, or divided block is too large; Coating is too thick, improper dilution. The coating itself have defects in performance. The temperature difference is big, weather suddenly cold, lead to the inner and outer drying speed is different, 'internal surface drying, drying,' result in the crack of the paint, etc. In view of the different reasons really stone paint coating cracking, can take the following corresponding preventive measures are: 1) Comprehensive repair of primary processing, the crack part and plaster leveling being dry flat rear can construction. 2) Pay attention to several thin coating, avoid too thick coating. 3) At the grass-roots level can be divided into appropriate to the size of the square. 4) Adjust the viscosity of coating, reach the medium viscosity, convenient for construction. 5) Adjustment of coating formula, to develop high quality stone paint products. 6) To prevent sudden changes in temperature result in the crack of the coating, should apply small nozzle spray gun, spraying layers. Should as far as possible to control the rate of each layer of dry. Spraying distance should be a little bit far. Empty drum off reason: coating construction when moisture content is too high at the grass-roots level; Due to insufficient age or on the base of the cement mortar and concrete curing temperature is low and strength is insufficient, mixed mortar base design strength is low, or the construction scale is not correct; The coating quality are not up to standard. Don't use the alkali resistant sealant; The coating surface is not completely dry, namely, coating the surface of the varnish coating, etc. Really stone paint falls off phenomenon often occurred in the empty drum Angle of Yin and Yang, windowsill, pipe root edge, greatly influenced by the rain the metope of the relatively weak position, etc. The reason is that the following several aspects: 1) Based on the edge of the pipe Angle and the roots of Yin and Yang, wall plaster team does not reach the designated position, uneven, straight, really stone paint construction team was not well done the handover check, without further processing, leaving hidden dangers. 2) Poor adhesion at the grass-roots level putty with wall body, be bored with child elements doping. 3) In really stone paint emulsion formula, in order to reduce costs, some manufacturers use less emulsion and more additives, resulting in a decline in adhesion. 4) Operating personnel technical level is low, the sense of responsibility is not strong, no pressure improper selection and large caliber gun, weak links to take effective preventive measures. Above is KeBao building materials common really stone paint yellow fall off in the process of the construction process. For really stone paint shed empty drum, we should deal with basic, remove dust and other viscous substances on the surface of the grassroots, will bump part broken and sand, hope so
