求翻译：待细磨完成后，采用滚筒、毛刷等将混凝土液体密封硬化剂材料均匀涂布在混凝土表面上，让混凝土液体密封硬化剂材料渗透入混凝土表层，渗透时间根据天气情况不同会有所不同，基本待混凝土液体密封硬化剂材料变得粘稠时开始清除；渗透的时间基本控制在20分钟至45分钟之间，如局部开始变干或将要成膜时及时喷水，并用毛刷或滚筒继续滚刷，最后将所有多余的材料清除干净；是什么意思？

After grinding completed, roller, brush, etc., liquid sealing of concrete hardening agent material uniformly coated on the concrete surface, to allow the concrete liquid seal hardener material penetrates into the concrete surface, the penetration time according to the weather conditions may be diffe
