What caused the short-lived really stone paint?

At present, most of the outer walls of the building will be completed really stone paint. However, some people say that, although the true stone lacquer is good, but its life is too short. In fact, really stone paint life is generally acceptable. What happened to the true stone lacquer is shorter? Ke fort really stone paint tell you. Really stone paint life really stone paint, exterior wall thermal stress: this is mainly refers to the local force caused by temperature difference between inside and outside change, this will lead to structural changes, such as exterior expansion shrinkage in a state of flux, increasing the coating latex material aging. Therefore, external wall thermal stress should be categorized as shorten really stone paint and the service life of the main reasons. Compared with the multilayer buildings and factories, the outer surface of the high-rise building, generally larger, or more the number of exposure in the sun. In exterior wall decoration design, therefore, suggest that choose flexible anti-cracking performance really stone paint putty, really stone paint surface to improve the ability of resistance to deformation. Two, facing wind pressure: generally speaking, exterior wall will produce positive and reverse thrust suction, both will make top really stone paint surface cracking, penetrating rain and mud. If really stone paint has a certain ability to resist wind, really stone paint construction no empty drum and layered problems, negative air pressure volume expansion might damage the outer wall of basement wall. Three, environmental moisture: to avoid water damage to the building, should choose not bibulous, hydrophobic good, really stone paint, in order to avoid water migration in the process of the wall the increase of water content, improve the water resistance and freeze resistance of really stone paint. Four, high fire: high-rise buildings are more stringent than multi-storey building fire prevention requirements. Exterior wall should really stone paint has excellent fire retardant function, to prevent the fire spreading, don't smoke or toxic gases. In addition, you should solve the problem of surface crack, flake coating, otherwise it's easy to create difficulties to residents of the rescue work. Five, the ground vibrations: seismic dynamic causes high-rise building deformation and deformation of structure and exterior wall coating. The hard really stone paint surface is, the bear the greater the shaking force, damage is more serious. This is the true stone lacquer coating on the premise of guarantee the adhesion, meet the requirement of flexibility, and reduce the load of surface layer, prevent large area crack, flake, or even fall off under the influence of surface vibration.
