Manulife plaster cracks from the main analysis of years of work experience in engineering and technical consulting services analysis, polymer surface mortar, cracks in the wall putty, cracks are many reasons. The main thing is to generate internal stresses due to shrinkage of the cement process caused by cracks, hollowing, shedding; secondly because of ground subsidence, earthquakes caused minor cracks, cracks; product of raw materials due to the use of models, specifications, quality meet the requirements and can also lead to poor product ratio improper bonding properties, prone to crack, crack, even hollowing, shedding; wall grassroots obvious cracks, breaks or the grassroots have powder, loose, oil and other phenomena, but also will lead to a crack, hollowing, shedding. Typically, whether horizontal, Hefei gypsum powder, as long as the straight line, cracks, it should be ground subsidence, the wall stress resulting actions. The case of a larger area of ??obvious Tortoise white gypsum powder, primarily grassroots, construction, as well as the product itself, the problem of poor crack resistance. Manulife plaster effective ways and technical methods to solve the crack, the crack problem is now some wrong understanding, one-sided that the polymer surface mortar, wall putty adhesive strength, the stronger the faster the better, the more elastic the better, and in fact is not After this plaster powder, cement hydration to form a strength, is rigid, can not be flexible, elastic can only be called the strength of cement did not meet the normal time of gypsum powder, furthermore highly elastic materials are highly The closure, which can be closed or even completely closed pores of cement, cement hydration hinder and prevent the use of the natural conditions for self-cement curing (breathing), is not conducive to cement stress release.
