Why really stone paint do frame and primer? Watching you will understand

Really stone paint more and more popular in recent years. Really stone paint have very strong adornment sex, is a kind of natural stone, marble and granite of thick slurry paint. Can provide natural color, natural stone texture, all sorts of line design, all sorts of three-dimensional shape design, can visually show the elegant beauty of the whole building. Next, KeBao building materials will share with you why really stone paint should be divided and primer. Division of labor is more difficult, but why do you still need to do this? Main purpose is to avoid large area concrete base surface cracks due to thermal expansion and cold contraction. Set up a certain number of grid nodes can reduce the area of a single concrete waterproof layer, thus reducing the coating cracks caused by inflation and warping deformation. At the same time, the grid lines as the border, in a more organized way for construction is also very convenient. In addition, the grid lines can also increase the aesthetic feeling of facade, won't appear too drab. It is well known that the base material of building external wall is mostly cement mortar or concrete surface, its characteristic is void, high basicity. Among them, the porous structure makes its water imbibition is strong, lead to really stone paint coating surface is not smooth, easy to cause the coating to wrinkling, and may lead to coating dry too fast, result in the crack of the paint and waste paint. Strong alkaline will lead to the chemical degradation of resin in the coating, coating aging faster, reduce the service life of coating, whitening and even FanJian. Alkali really stone paint primer of the present invention has excellent sealing isolation function, salt and alkali separated from really stone paint, good penetrated into the depth of the grassroots, make up the gap at the grass-roots level, have very strong mechanical bite, improve the coating adhesion. Overall improve and guarantee the service life really stone paint system. Coating finishing is the purpose of improving really stone paint coating waterproof, pollution resistance, resistance to ultraviolet radiation and other performance, and easy to clean in the future. If there is no finishing varnish, it is easy to make really stone paint coating is not water resistant, bleach, easy coloring, reducing the service life of really stone paint. Really stone paint, empty drum and loss is related to the underlying process. Uneven is caused by the uneven bottom processing. Hollow out the problem is caused by the bottom ballooning, which makes true stone paint feel puffy. Therefore, before spraying really stone paint, the underlying must undergo the appropriate treatment. In addition, the coating must be coated with a special primer before really stone paint, such ability can alkaline and moisture proof. Remove uneven, hollowing out, until not be removed, then remove float ash, moisture of primer, after waiting for primer is dry scrape waterproof putty, finally spraying really stone paint. Hollowing out phenomenon is often associated with base material. The poor quality of putty powder, improper handling before construction. This will happen. Really stone paint construction requirements as part of the coating thickness. On the one hand, ensures that the fullness of the coating, texture and vivid stone effect. On the other hand, to avoid the really stone paint construction process at the harmonic color different problem. In general, 2 - 3 mm can fully present the stone texture coating, in other words, 2 - Really stone paint thickness of 3 mm can fully achieve the quality of the ideal effect. There is absolutely no need to increase the coating thickness, resulting in additional costs. That is why KeBao building materials to share with you really stone paint. Why do you need to do partition and primer? I believe that after reading this article, you will have a classification of really stone paint and primer has a certain understanding. I hope this is helpful to you. Interested in really stone paint friend can read more about really stone paint the wall really stone paint price is determined by what factors? Let you seconds to understand an article 'information.
