Really stone paint falls off what is the reason?

True stone lacquer is a kind of vivid stone texture external wall decoration materials, can take advantage of natural stone texture effect. Usually really stone paint has the weather resistance and waterproof, can be applied to various climates, ideal for - service life 15 years. However, many really stone paint construction projects are often short of actual standard, lead to really stone paint falls off, white, yellow phenomenon. In the third part of the paint and some sections of the seven. As shown in the figure below, really stone paint is likely to fall off large area, it may not be the problem of paint. Instead, can really stone paint film and become an organic whole repeatedly, the emulsion content is higher, better quality paint. If really stone paint falls off into pieces, there may be several reasons: the reason one: basic mishandling metope residual ash 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. Reason 2: use putty leveling, don't mortar. Because 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 true 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. Reason 3: mortar in dry before the second daub, primer daub before drying. 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. Reason 4: a primer is not used or quality is not good, does not work. Preventing primer used in 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 level processing ( Loose surface and dust shall be removed before construction, ensure metope is firm, smooth, clean, no empty drum, no dirt. If mishandled, easy to cause foaming, alkalization, frosting, fall off wait for a phenomenon. 2: coating mortar, hanging net, apply twice mortar ( It is mainly used for leveling) 3: a primer ( Can effectively prevent the occurrence of basification, yellow, faded, seeping into the grassroots, binding mortar, play the role of connecting the mortar and really stone paint) 4: (twice really stone paint Really stone paint construction is the key to the suitable viscosity of coating, the first layer is a bit thin, should be uniform. After drying, spraying for the second time. When the second spray paint, paint will be
