I know: How many times is it appropriate to spray the construction of colorful water bag sand on the outer wall?

coating raw materials and equipment network:
water-wrapped sand (lychee surface, fire surface imitation stone): lychee surface, fire surface imitation stone should not only have a stone pattern of the color sense, but also have a lychee surface, fire surface stone surface color sand texture. With the touch of the hand should also have the convex surface of the original stone, in terms of particle color must be similar, particle color between the soft butt, from a distance to mix into a similar color, in the near to see to have the soft clarity of particles. Remember that on the market in real stone paint and texture paint spray water, this is not called water wrap sand, this is the last generation of water package water to do fire surface imitation stone paint method.At present, most manufacturers because of technical problems, still choose the last generation of products to do fire-face imitation stone, the effect is that the pattern layer is very thin, as if floating in the shape of the surface, color points appear very dull. Color point cover is coated film, is smooth, and the real lychee surface, fire surface stone pattern of the three-dimensional sense, surface scrub feeling is far from. At the same time, because the material of the medium coating and the main material is completely different, it is easy to produce the quality problem of coating film. At present, water-wrapped sand products can be counted as real lychee surface, fire surface imitation stone paint, its main material contains sand, coating film is relatively thick. After spraying, the pattern and shape are all in one, and the lychee surface, fire surface stone is closer. Water-wrapped sand coating compared to water-wrapped paint, its coating film strength is better, weather resistance is more superior, water-coated sand coating compared to real stone paint, its emulsion content is higher, its pattern simulation degree is richer, fuller, stone effect is more realistic, is the water-wrapped water coating and real stone paint advantages of the combination, blue out of blue and better than blue!How many times is it appropriate for the construction spray of colorful water bag sand on the outer wall? Many people in the external wall water sand construction, some once on the molding, but some are two molding, in the end is a good molding or two molding good?1, water-packed sand is divided into fire surface and lychee surface two, in the spray fire surface can be used once spray method, to complete once;2, in a spray fire surface, particles can barely do full spray, there will be dewy phenomenon, the market spray lychee surface color point particles basically can not do a full spray of 90 percent, but with 50 percent of particles to spray, so will certainly be exposed or no lychee surface texture.3, a spray molding due to the particle stacking pressure is relatively thick, not easy to dry, film-forming slow, there will be cracking, cracking, especially in the northeast to autumn and winter time, low temperature, slow drying speed, spraying is more likely to appear cracking, cracking, whitening and other irresistible phenomena.4, a molding of the thickness of the coating is not easy to grasp, especially for new sprayers, more likely to cause construction defects.5, a molding can not overcome the construction defects, but secondary molding can be for the previous process caused by the problem to take rescue construction. This defect is caused by the wall, some is caused by the paint formula, however, the construction staff may not understand these, if a molding then trouble comes, so secondary molding can play a role in the construction risk firewall.6, intuitively many people think that the secondary construction paint consumption is large, the theoretical basis is that the second construction twice hit the hard wall water-wrapped sand particles more. However, according to experience, one construction and secondary construction paint consumption is similar. Because the thickness of a construction is not easy to grasp, often sprayed thick, secondary construction atomization effect is good, with accurate paint, and then take into account the other benefits of secondary construction, the cost is actually similar.7, a molding can reduce costs, reduce construction risks. Sometimes the construction is to eat by the sky, especially in the south of the rainy season, if the wall is not dry, or rain, in the rush time situation may be reluctant to work, if it is a molding after the discovery of paint white loss is large, if the first thin spray once, dry after the paint surface did not white, basically no big problem, in case there is a little white, delay the construction period of the second construction can also cover it. Even if the duration is too tight must be constructed, then the dry after the previous water-wrapped sand on the follow-up water will play a blocking role, for the secondary construction of the paint drying to buy time, such as paint dry after the water will seep out will not be white.8, a molding because the amount of paint is too large sprayed out often particles are not uniform enough, in the case of unstable gun pressure and so on will have the phenomenon of not covering the bottom. Secondary molding will supplement the dewy bottom phenomenon, to achieve the ideal effect (less paint, fan atomization effect is good, easy to control, spray out very flat).9, according to the construction experience, for yellow, red, orange, coffee color these colors in particular to secondary molding, otherwise it is easy to "flower" off.Disclaimer: Part of the content of this article comes from the network, we have indicated the source, copyright belongs to the original author!
