Really stone paint four of the most common lacquer disease how can we prevent? 2020 KeBao paint

Nowadays, the urban construction and the outer walls of the cottage to use real stone paint. Because really stone paint production itself and the construction process, the influence of the film quality really stone paint, adornment effect, problems such as wasting material, is bound to affect the totality of really stone paint beautiful decoration and service life. Next, KeBao building materials to share with you four of the most common disease really stone paint coating, and how should we prevent them. Water whitening whitening really stone paint coating water main show: although the coating completely dry, but is still in the water whitening, coating will become loose. After drying, 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 bentonite, etc. And use strong alkali resistance of seal primer. Paint film is too soft on besmear after really stone paint, coating within 3 days after the good weather conditions will still be a nail scratch, this is the so-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 film forming additive basically can volatilize, generally will not affect the performance of the coating. Drop off in the process of sand spraying sand spraying process refers to the spray too much construction, under the normal spray pressure and spacing, paint easily falls off phenomenon. Some really stone paint will drop more in the process of spraying sand, lead to enormous 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 the bentonite. The reason of the difference of color difference really stone paint showed excellent may be associated with 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, time limit after partial metope because in the rain, unable to work in a dry environment construction, result in color difference. 4) Uneven color mixture, the result is that KeBao building materials a total of four of the most common disease really stone paint paint. How should we prevent them? Really stone paint diseases for many reasons, is usually caused by wrong selecting raw materials or construction or external environment. I hope this is helpful to everyone. Interested in really stone paint friend can read more about really stone paint 'really stone paint colour difference problem in where? Is not necessarily a problem of product information.
