Wall paint is actually what people call latex paint. As one of the decoration materials, it occupies a relatively large proportion in paints. However, choosing a good wall paint is very important, but the formaldehyde in the wall paint is also very troublesome for consumers. Next Xiaobian introduced the purchase techniques of wall paint and the characteristics of exterior wall paint. Wall paint purchase skills 1, hiding power Can see the hiding power of paint, with a black and white grid to show the minimum amount of paint, generally the greater the weight, the weaker the hiding power, and the stronger the hiding power, the less the amount of paint per unit area. 2, adhesion The adhesion of the wall paint can be seen. If the bond between the coating film and the coated surface is firm, the coated side can be a bare substrate or a painted substrate. The wall paint with weak adhesion is easy to fall off, affecting the appearance of the wall. 3, viscosity Viscosity is an important indicator to inspect the wall paint. When the viscosity test is performed, it can be measured with the paint viscosity measurement instrument. If the paint is too thick, it is not easy to brush, and it is too thin and easy to fall. Therefore, the viscosity of the paint must be controlled at a certain level. In the range. 4, fineness The size of the fineness will affect the smoothness of the surface of the coating film, as well as the light transmission, etc. Generally, the finer the coating, the more expensive it is. Exterior wall paint features 1, good decorative The exterior wall paint has a better decorative effect and can maintain the original decorative performance for a long period of time. 2, good weather resistance Exterior wall paint is mostly used outdoors, so it is subject to sunlight, rain, sand, etc. Under such circumstances, cracking and falling off are likely to occur. The outer wall paint has good weatherability, and its coating requirements are specified. The above-mentioned damage does not occur within the age limit. 3, good stain resistance The pollution of the environment is getting worse and worse. The dust in the air will be covered with the entire coating and will lose its decorative effect. Therefore, decorative coatings for exterior wall finishes are not easily contaminated by these substances or are easily removed after contamination. 4, good water resistance Even if the outer wall paint is under the baptism of heavy rain, it will not receive damage. Therefore, the exterior wall paint has very good water resistance. When cracks occur on the base wall, the coating film remains intact and has a waterproof function. 5, good mold resistance The anti-mildew property of the exterior wall paint is good. Even in the long-term moist environment, mold and algae growth will not occur. Editor's summary: The purchase of wall lacquer and the characteristics of the exterior wall paint are introduced here. I hope to help everyone. If you want to know more related information, you can pay attention to this website information.
