Abstract

The invention discloses a repair method for a local crack of hardened floor, relates to the technical field of architectural ornaments, and aims to the problems that the repair method for the local crack or pit of the hardened floor is long in construction period and high in construction cost, and the color of the colored hardened floor is non-uniform. The repair method comprises the following steps of first, filing the crack or pit in an area to be repaired with a repairing agent, and performing targeted repairing on the crack or pit; then, uniformly spraying a curing agent on the surface ofthe hardened floor, fully soaking and grinding; and finally, coating the surface of the hardened floor with a water-borne protective agent, and grinding and polishing. And the purpose of densely modifying the interior of concrete is achieved; and the repairing effect of the crack or the pit is improved fundamentally.

Description

technical field [0001] The invention relates to the technical field of architectural decoration, in particular to a method for repairing local cracks in hardened floors. Background technique [0002] Hardened floor is a concrete floor containing mineral alloy aggregates. It has the characteristics of dustproof, anti-skid, wear-resistant and strong decoration. It is widely used in industrial plants, parking lots and other places. However, when plastering the poured concrete surface, obvious tortoise cracks often appear on the surface of the hardened floor due to shrinkage cracks, or coin-sized pits appear on the surface of the hardened floor during other subsequent constructions, thus Affect the overall performance of the hardened floor. [0003] At present, there are two ways to deal with local cracks or pits in the hardened floor: [0004] 1. Repair by glue injection, using urethane or acrylamide polymer grout to react with water to form solid sediment or foam material to...
