Water sand bags and colorful construction coating, spray a few good?

Compared with water package of water type coating, water sand mold coating has better film strength and weather resistance. Compared with the really stone paint, water bag sand coating has higher content of emulsion, richer, more full of design simulation and more lifelike stone effect. This is water bag water coating and in combination with the advantages of really stone paint, shine on you more than the blue! Outside the wall spray color of water and sediment package many times right? When many people are in construction of exterior wall of water bag of sand, some of them are of one step forming, some of them are two steps to shape. It is formed step or two step form? Shaw will discuss with you: 1. The sand in the water can be divided into two kinds: burning surface and the surface of the lychee. When burner noodles, can use a spray method. Litchi surface must brush twice. 2. A burner good noodles, particles can hardly complete, there will be a show at the bottom of the phenomenon. Spraying on the market of litchi was almost amounted to less than 90% of the total spraying, spraying but 50% of the grain, so the bottom will certainly be exposed, otherwise, litchi surface, there is no sense. 3. A injection molding is not easy to dry, because the particles of relatively thick laminated degree, and its membrane performance is slow. When the temperature is low, the drying speed is slow, especially in the northeast of qiu dong season, may appear crack and craze. After spraying, it is easier to appear irresistible phenomenon, such as crack, cracking and turned white. 4. A shape is not easy to control the thickness of the coating, especially for the new spraying hand, are more likely to cause construction defects. 5. A molding can't overcome the defects of construction, but the secondary forming can be caused by the previous process to take remedial construction. Some defects are caused by a wall, some of them are caused by coating formula. Construction personnel, however, may not know that, if they have a molding, trouble came. As a result, secondary forming can be used as construction risk of firewall. 6. Intuitively, a lot of people think that the second construction will consume large amounts of paint, theoretical basis is the second time construction will use more water and sand hit hard wall twice. According to experience, however, a building in the consumption amount of paint and the second building in roughly the same amount of consumption of paint. Due to the thickness of the first construction is not easy to master, so often spray thicker, atomization effect is good, the second construction paint quantity accurately, considering the second construction of other benefits, the cost is actually the same. 7. One step forming can reduce cost and risk of construction. Sometimes construction depends on the weather, especially in the south of the rainy season, if you don't dry wall, or rain, under the condition of the time limit for a project may be difficult to construction. If after a molding find paint white, losses will be very big. If you gently spraying, drying after the paint is not white, basically there will be no big problem. If a bit pale, can also be covered when the second delay during the construction. Even if the construction period is too tight, the construction is necessary, the sand will be dry after the first water blockage of subsequent water, for the second construction paint surface drying time, dry paint surface water won't become white. 8. For a forming, due to excessive paint, particles tend to be uneven, the bottom will not be covered under the unstable pressure gun. Secondary forming can be added at the bottom of the leakage phenomenon, to achieve the ideal effect, The paint quantity is little, fan atomization effect is good, easy to control, smooth discharge) 。 9. According to the construction experience, yellow, red, orange and brown should be special molding twice, otherwise easy to 'blossom'. According to the formation of a sand layer or the second water situation, everyone after reading analysis should have a clear understanding on this point. I hope the water gush arenaceous knowledge help you.
