工程验收结束，发现墙体出现大面积小裂缝，已粉刷好了外墙漆该怎么处理呢？ - 工程施工 - 项目管理 - 氿上知道

1、可能是腻子或者石膏太太厚，干缩厚出现的小裂缝，如果应付验收的话，同意楼上意见；但是后续还是要处理的，看是否为砂浆层空鼓，如砂浆层空鼓的话应剔除空鼓部分，将基层处理后（刷浆、做毛，增加粘接力）后重新抹灰并粉刷。
2、如果只是粉刷层开裂，则剔除粉刷层，在裂缝部位增加加强绷带后重新粉刷即可。
墙面小裂缝产生的原因有多种，主要如下：
1、粉刷分层厚度大；
2、砂浆配合比差异；
3、砂的含泥量较高；
4、季节因素施工；
5、拌制的砂浆闲置时间较长，未及时进行粉刷。
鉴于在处于验收阶段，先可使用小锤轻轻敲击，如无空鼓现象，在表层再次涂刷涂料面层可暂时遮挡细微裂缝。不过大面积开裂的现象经1-2年的时间必然会造成空鼓，导致粉刷层掉落和引起墙面渗水，所以在保修期内还是比较麻烦的。
