Why really stone paint falls off, the reason here

At present, many foreign companies choose really stone paint as decoration. Really stone paint, 真正的石头漆) Is a kind of exterior wall decoration materials, vivid granite texture, can take advantage of natural stone texture effect. Under normal circumstances, really stone paint has the weather resistance and water resistance, can be applied to various climates, for - service life 15 years. However, many really stone paint construction, often can not meet the actual standard, cause really stone paint falls off, white, yellow wait for a phenomenon. These three kinds of material is divided into seven parts. True stone paint falls off large, this may not be the problem of paint. Fall off several likely a factor: improper handling at the grass-roots level; Residual gray metope too much will affect the degree of the combination of wall with mortar layer. Before construction, loose surface shall be removed and the floating dust, ensure metope solid, smooth, clean, no empty drum and dirt. With putty, without mortar. Because of the really stone paint and putty is not high, spent so really stone paint should use mortar leveling. If you have not professional construction team, with putty, can lead to big really stone paint falls off. If walls with really stone paint, construction with mortar leveling, hang a layer of grid cloth, reoccupy mortar leveling, paint primer, will greatly improve the service life. Mortar recoat time is short, in front of the mortar dry primer. Mortar completely dry climate condition has a lot to do with the length of time. If the weather is good, the air humidity is not high, slurry drying time will be shorten, and vice versa. In good weather conditions, When the temperature is about 25 degrees) , thoroughly dry mortar can be in three hours time, mortar is usually twice a day is enough. However, this process should not be in a hurry. Only mortar dry, polishing and painting. Primers and paint drying time should be according to the actual weather conditions, rain and high humidity of the air may be extended appropriately. Under normal circumstances, the first side can paint 3 - after the primer coating Coated within 4 hours and the second can finish 2 - after the first paint dry Three hours of coating. Do not use primer or primer quality is not acceptable. Preventing primer is closed alkali, alkali to the surface, the influence of the surface of the visual effect. 2 it is fixed at the bottom, the penetration to the bottom, fixed mortar, which connect mortar with true stone paint. If the primer can fixed mortar, it will lose the basic function, after the brush, it will also make true stone paint falls off from the wall. In addition, the primer is black and transparent, it is best not to mix colors. If primer blend color, can save material, but affect the penetration. Initially, the need to 4. 5 kg really stone paint to cover primer, in order to achieve good visual effect. When the primer is adjusted to the same color as the really stone paint, only 3 kg may be sufficient. Save the material. However, before long, really stone paint will be large loss. If you want to avoid some of the common paint problem, you should avoid some common mistakes in the construction, for example, to do the basic cleaning of metope, pay attention to the humidity of metope, 24 hours to avoid the rain, the weather is good to avoid in damp or cold weather construction, etc. Really stone paint professional construction steps: 1. Basic processing ( Loose surface and dust shall be removed before construction, to ensure a solid, smooth, clean, no empty drum and dirt. Improper handling can easily lead to blister, alkalization, flowering, fall off. ) 2. Scraping slurry, hanging net, secondary mortar ( It is mainly used for leveling) 3. Primer ( Can effectively prevent the occurrence of basification, yellow, faded, seeping into the grassroots, binding mortar, mortar and really stone paint connection effect) 4. Two really stone paint ( Really stone paint construction is the key to the proper consistency of paint, spraying a thinner for the first time, second spraying dry evenly. Second spray paint, the paint will be more and more thick) 5. Spray paint ( Paint has very good protection effect to the really stone paint, improved really stone paint layer of contamination resistance, resistance to ultraviolet linear and high weatherability, can prevent really stone paint layer falls off
