墙砖为什么会脱落？
功能需求: 增加房间
我家最近正在装修，已经准备完工了，但是卫生间的墙砖突然就掉下来了，不知道是啥情况，装修师傅说是瓷砖问题，有谁知道墙砖为啥会突然掉下来吗？

一般不会是瓷砖的问题，墙砖的施工工艺是分两大类，一、瓷片类工艺，因为瓷片规格小并且密度低，所以泡水后直接刮浆铺贴就行，不会掉。二、瓷砖类，也是现在主流，瓷砖和地砖是一样的，密度高，规格大，重量大，贴墙容易脱落，所有就需要一些措施，第一：墙面清理，墙面如果有腻子等脆弱的墙面装饰需要全部铲下来。第二：拉毛，把墙面用专门工具刮的有棱槽，目的是贴瓷砖的砂浆和原有墙面粘贴的更牢固。第三：刷背胶，在瓷砖后面刷一层高粘性的物质，目的是让瓷砖和贴瓷砖的砂浆之间粘的更牢固。第四：粘结剂，在贴瓷砖的砂浆里加入适量粘结剂让砂浆本身粘性更高。
以上所有步骤保证工艺和材料没问题就不会掉
以下为瓷砖可能脱落的原因，你自己根据实际情况看是什么问题：（前提是按照我上述方法施工，如果不是按照我说的弄或者少了几个步骤，那就肯定有问题）
1.辅料也就是上述说的粘结剂背胶等东西质量问题
2.师傅的水泥砂浆及粘结剂比例问题（可能性小）
3.水泥质量问题或沙子大小不对（可能性小）
4.墙体本身问题，有很多开发商的原有墙体用钥匙都能划一个深槽，那就贴不住砖
另外，你要看掉下来的砖后面是带着水泥砂浆还是不带，带着说明是水泥砂浆和墙体接触的问题，不带就是瓷砖和水泥砂浆的问题。
