性能指标

使用方法

1、基层要求及处理
打磨去除混凝土基层表面的疏松层,露出坚实骨料,彻底扫净表面浮灰,基层要求坚固,干燥;无贯通宽裂缝。

2、材料配制
RJ90胶液配比:RJ90甲组份 :RJ90乙组份=31(重量比);
RJ90砂浆配比:RJ90甲组份 :RJ90乙组份:RJ90粉料=314~6(重量比),根据气温、立面或平面施工调整Z90粉料用量;
甲、乙组份取料容器分开使用,每次配料不宜过多,随配随用,30分钟内用完。

施工

涂刷界面剂:将界面剂搅拌均匀,采取滚涂或刷涂的方法,在处理好的基层上涂刷均匀,厚薄一致,确保完全涂满基层。间隔0.5~4小时(根据气温初凝后)可以进行下道工序;
压抹砂浆:在胶液涂刷后表面变粘( 手触胶液有拉丝现象), 立即压抹配制好的RJ90砂浆,同时压实收光;
养护:干燥养护7天,可使用。

用量、包装及储存

 

用量:6kg/m2左右(以结合层厚度4mm);
包装:RJ90甲组20kg/桶,RJ90乙组20kg/桶,RJ90粉料25kg/;
