What is the cause of the really stone paint off the sand? Watching you will understand

Really stone paint is the most popular exterior wall coating. Really stone paint because of its environmental protection, natural material, low cost, beautiful and easy, and is widely used in architectural decoration industry. However, the shakeout phenomenon also headache in the process of construction. Some really stone paint will drop more in the process of spraying sand, cause the cost of serious waste, indirectly increased the cost of materials. Next, the lacquer that bake will tell you why the sand will be dropped from the true stone paint. Raw material: currently, really stone paint with sand has two kinds: artificial sand and natural sand. According to the observation, from really stone paint made of natural sand removal of sand amount is less than the artificial sand. Recipe: affected by really stone paint viscosity, in general, really stone paint is too dry, in the process of spraying of base material wet adhesion is poor, often leads to high sand ratio. Climate: summer construction, true stone lacquer is the highest temperature at noon when spraying. Really stone paint after the atomized spray to the base material in the process of water loss is very big, lead to reach the surface of the base material really stone paint when wet adhesion is poor, a significant sand drops. Construction: in the construction under the influence of air pressure, high pressure will make the color sand on the surface of the lack of mud packages, weakening of base material wet adhesion, at the same time, the reaction of base material is large, lead to high sand ratio. When air pressure is low, spray atomization is bad, spraying a floating effect, less sand drops. Dilution consistency: difficult construction really stone paint is too thick, if it is too thin, the daub on a wall of sand viscosity is too low, can lead to sand fall off. So. In really stone paint construction process, should strengthen the consistency of really stone paint, as far as possible to help solve the problem of falling sand. To remove sand from really stone paint, therefore, the problem is influenced by many factors. In the case of raw materials and formulation cannot accurately identify, spray can try to see the quality of the construction in the process of buying really stone paint, and master the temperature. Low temperature also easy to cause the phenomenon of really stone paint white, also easy to cause high temperature really stone paint sand-out phenomenon, we should also control the pressure of the spray gun, do not require rapid construction. After all, has the problem of waste material cost, rework is also very trouble. That is really stone paint off KeBao building materials share the cause of the sand. When you build, you must pay attention to this situation. Some really stone paint spraying when more sand, about a third of serious cases will fall, causing serious waste, the cost of indirect increased cost of materials. I hope this is helpful to everyone.
