Concrete repair agent is a product specially designed to repair ground cracks and pores. It is a water-based environmentally friendly liquid. It has a good repairing effect on new and old ground cracks and holes, but many customers do not use the concrete repair agent because the method is not satisfactory. Next, let me introduce the correct use of concrete repair agents.
Clean the concrete surface and fully wet it with water, but the surface must not have clear water. Apply a concrete repair agent to the area to be repaired with a brush (or roller) to allow the repair agent to fully penetrate the hole. The concrete repair agent and cement (or the appropriate pigment according to the color of the concrete) are mixed into a repair mortar in a ratio of 1:2-4 (according to the size of the defective hole, appropriate addition of fine sand and crushed stone aggregate). The repaired mortar is filled into the hole of the concrete, compacted and leveled, slightly higher than the concrete surface, and the repaired mortar is now used, and the cement is used up before the initial setting.
