　　Heilongjiang putty powderWhat about cracks, cracks and dark marks
　　Cause:
　　1, due to the influence of external factors on the building wall cracking phenomenon, such as temperature expansion and contraction principle, foundation subsidence and other external factors。
　　2, due to the incorrect proportion of mixed mortar in the curtain wall, when the viscosity is high, the wall will shrink and lead to cracking and cracking after the wall dries out。
　　3, the cracking phenomenon of putty powder will basically form small micro-cracks on the wall, like chicken feet marks, turtle shell marks and other shapes。
　　Treatment method:
　　1, because external forces are uncontrollable, more difficult to prevent;
　　2, the mixed mortar wall should be dry before the putty powder batch scraping construction;
　　3, such as putty powder cracking should be confirmed by the company's technical personnel to the scene according to the actual situation of the wall。
　　注：
　　1, door, window, beam edge cracking is a normal phenomenon;
　　2, the top floor of the building is more susceptible to thermal expansion and contraction of the impact of cracking。
