Prepare and Wet the Concrete Surface

What happens here

Begin by ensuring the concrete surface is clean of any loose debris. Then, liberally apply water to the entire concrete surface using a plastic bottle or a hose. Keeping the surface consistently wet is crucial for effective wet sanding, as it helps lubricate the abrasive, prevents dust generation, and carries away concrete particles, forming a slurry.

Goal: Ensure the concrete surface is adequately wet for sanding.
