水泥砂浆坐砌隔热砖。隔热砖距女儿墙内边不少于250。六、注意事项：1、基层表面应清洁光滑平整，无渗漏，无积水，严禁带水、带泥施工。平整度用 2M 直尺检查，最大空隙不应大于5mm，不得有空鼓、开裂及起砂、脱皮等缺陷，空隙只允许平缓。阴角处应做成直径 50mm的圆角。阳角处应做成直径 10mm 圆角，角度应为135o，其边长不小于 12cm。2、如基层为混泥土25、结构而且不平整，可进行局部修补整平，然后满刮一道 HQB 高分子防水剂，将气孔、小孔堵塞平整。不得在特别潮湿、不通风的环境下施工，否则会影响成膜质量。4、基层应坚实，平整光滑，均匀一致，无空鼓、凹坑以及掉皮起砂等现象。5、涂层分多次进行，力求均匀，切不可出现漏涂现象，一定要待前一次涂的材料成膜，方可进行下一次涂刷工作，前后两次间隔时间具体视气温高低、空气湿度大小而定，涂刷方向要垂直，直到防水层达到 2mm 为止。七、产品保护：1、涂膜完成后，不得随意刻划涂膜表面，不得持任何硬物在涂膜上拖行，不得堆放重物、硬物。2、当立壁涂膜采用水泥浆保护层则要在最后一遍涂膜固化前，撒上一层干砂，以利于增强与水26、泥砂浆保护层的粘结力。3、常见质量问题：ndoverallleadershipresponsibilityforsafety.AdministrativeDeputyiswit

气孔、气泡：材料搅拌方式及搅拌时间未使材料拌合均匀，施工时，基层处理不干净，做涂层前应仔细清理基层，不得有浮砂和灰尘，基层上更不应有孔隙，涂膜各层出现的气孔应按工艺要求处理，防止涂膜破坏造成渗漏。b 起鼓：基层有起皮、起砂、开裂、积水31、，使涂膜粘结不良，基层施工应认真操作、保养，待基层符合防水施工要求后，先涂底层涂料，固化后，再按防水层施工工艺逐层涂刷。c 涂膜翘边：防水层的边沿、分项刷的搭接处、出现同基层剥离翘边现象。主要原因是基层不洁净或积水，收口操作不细致，密封不好，底层涂料不粘。d 破损：涂膜防水分层施工过程中或全部涂膜施工完，未等涂膜固化就上人操作活动，或放置工具材料等，将涂膜破环、划伤，施工中应保护涂膜的完整。八、工程质量验收标准检验项目要求检验方法主控项目防水涂料和胎体增强材料必须符合设计要求检查出厂合格证、质量检验报告和现场抽检报告涂膜防水层不得有渗漏或积水现象.雨后或淋雨、蓄水试验。涂膜防水层在天面、檐沟、32、檐口、水落口、变形缝和伸出屋面管道等处细部做法必须符合设计要求观察检查和检查隐蔽工程验收记录表ndoverallleadershipresponsibilityforsafety.AdministrativeDeputyiswit
