纸面石膏板由于其本身材质的限制,接缝开裂一直是个难题,尤其在交工后一年左右时间,裂缝产生更为明显。要解决这一难题,我们认为必须在嵌缝上下功夫,用弹塑体材料代替目前使用的791石膏腻子,才能解决开裂问题。因此,我们在处理两个公共建筑的吊顶及厕浴间石膏板接缝上,采用了以下方法。通过一年的实践和使用,效果良好。其做法如下:一、材料与工具弹性防水密封膏:白色或透明均可。使用非下垂型,固化时间24～72小时为宜,且微量收缩不产生裂纹,与表面装饰材料不发生反应,贮存时间不
Because of the limitations of its own material, plasterboard cracking has always been a problem, especially in the one year or so after the completion of work, cracks are more pronounced. To solve this problem, we believe that we must work hard on the caulking to replace the currently used 791 gypsum putty with an elastomer material to solve the cracking problem. Therefore, we used the following methods to deal with the gypsum board joints between ceilings and toilets in two public buildings. Through one year of practice and use, the effect is good. Its practice is as follows: First, materials and tools Flexible waterproof sealant: white or transparent can be. The use of non-sag type, curing time is suitable for 24 to 72 hours, and the micro-shrinkage does not produce cracks, does not react with the surface decoration material, storage time is not
