How to prevent disease really stone paint four big? 2019 KeBao paint entire network

Really stone paint is the most commonly used exterior wall coating. Really stone paint appear gradually replaced the outer wall of ceramic tile, and be used for many wall engineering. Because really stone paint production and construction process, the influence of the film quality really stone paint, adornment effect, material waste and other issues, will inevitably affect the whole beautiful decoration really stone paint and service life. Next, KeBao building materials will share with you really stone paint four Chinese lacquer disease prevention method. 1 water whitening whitening really stone paint coating water main show: although the coating has been completely dry, but will still be whitened and loose in the water. After drying in the sun, the coating is still unable to restore the original color. Really stone paint in white water basically has the following reasons: really stone paint added during the production: inappropriate emulsion. Emulsion manufacturers use too much because some surfactants, to increase the stability of the emulsion, the presence of these surfactants would significantly reduce the resistance to water of emulsion itself. In order to save costs, really stone paint manufacturers only add a small amount of lotion, makes the dry film loose and dense enough, paint film is bibulous rate is relatively high, cohesive strength is relatively low. In the rain for a long time, the rain will gradually into the paint film, really stone paint film to bleach. To solve the problem of paint with water to bleach, really stone paint use special styrene acrylic emulsion and pure acrylic emulsion, or appropriate to add silicon sol or silicon fertilizer. It can improve the resistance of paint film is pale, hardness and adhesion. In addition, by choosing appropriate additives, such as special 217 bentonite, etc. And use strong alkali resistance of seal primer. 2 really stone paint spraying paint film is too soft after construction, in good weather and environmental conditions, three days after the coating will still be a nail scratch, this is called coating is too soft. Emulsion to incorrect or insufficient emulsion content leads to the formation of a paint film coating is not quite close together, this is a major cause of soft really stone paint coating. The solution is to choose a special type of emulsion preparation really stone paint, the minimum film-forming temperature should not be lower than 20 ℃. If the minimum film-forming temperature is higher, when the air temperature is low may not be easy to film, this can be achieved by adding proper film forming additive to solve. After coating is dry, the amount of basic volatile film forming additive, generally will not affect the performance of the coating. 3 spraying process out in the process of sand spraying out too much sand in the construction of spraying is refers to the application really stone paint, paint easily in the normal spray pressure and spacing out the phenomenon of sand. Some really stone paint will drop more in the process of spraying sand, cause huge waste. Because in addition to the construction method of factors, raw materials and formulation can also cause this phenomenon. Made of natural colored sand really stone paint greatly reduces the degree of sand removal. In the preparation of really stone paint, the color of sand grading is also very important. Appropriate grading really stone paint is not only cut off in the process of spraying sand, and coating. In addition, the viscosity of the coating shakeout phenomenon in the process of spraying has a certain influence. When the paint is too thick, not easy to spray paint, construction difficulties. When the coating is too thin, color sand on the walls of the low initial viscosity, easy to cause sand fall off. In construction without difficulty, therefore, the viscosity of the coating should be increased, as soon as possible to help solve the problem of off the sand. However, excessive thickening can lead to poor resistance to water, so you can use 217 bentonite. 4 color difference really stone paint shows excellent color difference. The reason may be associated with the following factors: 1) The amount of each building materials once is not enough, different batches of material color deviation, caused chromatic aberration; 2) Construction personnel technical level is uneven, resulting in uneven thickness, local thinning and color difference. 3) Because of the influence of the weather, because of the limitation of a construction period partial metope can't work in the dry environment construction. 5) Before spraying, coating need to stir to mix well. This is KeBao paint to share with you the four big paint disease. In really stone paint exterior wall construction, everyone must pay attention to the above four, to ensure the perfect construction of really stone paint, hope to be of help.
