These problems really stone paint construction should be how to solve? 2019 KeBao paint entire network

Really stone paint construction often encounter some problems. 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 how to solve the problems in really stone paint construction. 'Coating too soft' really stone paint spraying after construction, in good weather conditions will be three days after a nail scratch, this is called the coating is too soft. Emulsion to incorrect or insufficient content of emulsion 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, bond strength should not be less than 3 mpa, the minimum film-forming temperature should not be less than 20 ℃. Higher minimum film-forming temperature may make it difficult to film forming at low temperatures, this can be achieved by adding proper film forming additive to solve. After coating is dry, the amount of film forming additive basically can volatilize, generally will not affect the performance of the coating. Coating fall off when they have too much sand spraying really stone paint falls off will have too much sand, this refers to the normal spray paint falls off easily under pressure, and spacing of the phenomenon. Some really stone paint will have a lot of sand in the process of spraying, in serious cases can reach 1/3, cause huge waste. In addition to the factors of construction method, the above phenomenon can also be caused by raw material and formula. At present, really stone paint with sand has two kinds: artificial sand and natural sand. Has been observed from really stone paint made of natural sand to remove sand amount is less than the artificial sand. This may be associated with the hardness and surface state of sand. In general, high hardness, smooth surface density of sand is easy to fall off. In addition, in the preparation of really stone paint, sand grading is also very important. Appropriate grading really stone paint is not only cut off in the process of spraying sand, and coating. Therefore, we suggest that in the preparation of really stone paint, as far as possible the use of natural sand, sand should be graded. Were used in this study shows that the lower and less sand loss in the construction process, and the coating quality is better also, particle size of more than 10 5%, 10 - 50 25%, 50 - 100 50%, less than 20% 100 mesh. 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 paint is too thin, the wall of sand low initial viscosity, could easily lead to 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. 1) The amount of each building materials once is not enough, different batches of material color deviation, lead to off color; The reason of color difference may be related to the following factors: 1) The amount of each building materials once is not enough, different batches of material color deviation, lead to off color; 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 in the rain in the time limit, after can't work in a dry environment construction, cause off color. 4) Uneven color mixture will result in color difference. 5) Coating store, a layer or surface layer is floating color, did not fully stir well before spraying. According to the reasons of the color difference, can take the following measures to prevent the poor really stone paint colour: 1) The same walls, the same color really stone paint, should use the same batch number, the same paint manufacturer of construction, quantity should be one-time purchase. When the batch number is not of the same color at the same time, should mix in advance, to ensure that does not produce off color metope. Construction process, the wall from top to bottom seam is divided into a grid, Yin and Yang Angle or drain pipe, as piecewise line construction. 2) Improve the operation of the c
