The five main reasons really stone paint short-lived

True stone lacquer is a kind of widely used in exterior architectural coatings products, accounts for the largest proportion of the whole metope outer protective structure. Nowadays, environment change more and more fierce, true stone lacquer is actually affected by more factors. The key point is really stone paint accelerated aging, lead to actual quickly shorten service life. One, the external wall thermal stress mainly refers to the local force caused by the wall temperature difference between inside and outside, it will cause expansion and contraction of the external wall of structural changes, such as to be 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 in general, 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 water vapor 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.
