The early stage of the concrete polishing process includes four steps: grinding (coarse grinding), repairing, curing, and polishing (fine grinding). Generally, it is necessary to further adjust the tools and steps used according to the actual situation to achieve the final design effect.
(1) Grinding (coarse grinding) refers to the use of metal diamond tools for grinding, which can remove fine pits, blemishes, colorants or other thin coatings on the floor (such as epoxy coating, self-leveling cement, PVC plastic ground, etc.) To prepare for the subsequent polishing process. According to different concrete floor conditions, the grinding process can usually be divided into three to four steps.
(2) Repairing refers to the use of repairing agent to fill in the air bubbles, cracks, and fine cavities in the concrete.
(3) Curing refers to the process of applying curing agent on the surface of the concrete to harden the concrete.
(4) Polishing (fine grinding) refers to the use of resin polishing pads to polish the floor until the floor exhibits the expected gloss. The polishing process can be divided into three to five steps. According to the floor conditions and gloss requirements, the maximum usable number of resin polishing pads is 3000 grits. According to the glossiness of the polished surface, the polished concrete floor can be divided into three categories: industrial floor, commercial floor and top floor.
