What is the treatment method for sanding on cement pavement?

[Nigel]

Direct spraying ensures that the base layer is fully saturated and absorbed. Continuously replenish the absorbed material to maintain a saturated state, ensuring the entire ground is thoroughly permeated. At least 48 hours after construction, apply Material #2 directly to the hardened ground surface in a single, even, and generous coat. No additional curing is required. If sanding is severe and the surface layer is peeling, the ground should first be coated with a treatment agent. Once dry, mix this treatment agent with cement and apply it evenly to the ground. Inadequate or untimely curing, exposure to intense sunlight, or strong winds can cause excessive water loss from the concrete surface, preventing sufficient hydration and resulting in lower strength.
