1. Base surface treatment: Appropriate treatment should be carried out according to the specific situation, such as removing curing agent, oil stains, dust, building laitance, wall residues and removing loose materials left on the base surface.

2. Use a grinding machine with 30, 100 mesh, and 300 mesh resin grinding pads for grinding (wet grinding with water). Grind 3-5 times depending on the ground conditions. The ground should be treated as flat as possible. The flatter the ground, the better the later effect. Depending on the ground conditions, you can choose not to do 30 and 100 meshes.

3. After the ground is dry, spray a sealing and curing agent on the ground, apply it evenly, and keep the surface moist for more than 20 minutes.

4. After the ground is dry, use a grinder with 500 and 1000 mesh grinding pads to dry the ground. Grind 3-5 times depending on the ground conditions.

5. Spray a lithium-based concrete sealing and curing agent on the ground, apply it evenly, and let it dry.

6. Finally, dry the ground with a high-speed polishing machine.
