二、使用方法及注意事项

1.50kg快速修补砂浆加入6.35升水可生成22升砂浆。

2.被修补的表面必须是结构良好,先将损坏的混凝土清除干净表面无灰尘,油脂等污物及碳化砼、呈粗糙面。在修补周围至少凿去20MM、防止边缘留有已损坏的混凝土;保证新老混凝土界面的粘结强度。

3.施工时用清水混润修补处,先把灰尘、泥浆去除,无积水状再进行浇捣。

4.用搅拌机(或人工搅拌)将干料与清洁水(自来水)搅拌2-3分钟,即能得到均匀料液。

5.搅拌好的料液快速倒入修补处,必须用机械振捣密实一次抹平即可。

6.当气温低于15℃施工时,宜用&40℃温水搅拌,认保证砂浆的早期强度。

7.严禁与其它品种水泥混用。
