Tip

After polishing, you can easily take the next step and stain your concrete with great results. Some handheld grinders require a wet application. They need to be used on a wet concrete surface. Follow the manufacturer’s instructions for using your handheld sander.

  • Vacuum the area thoroughly to remove all dust and debris. Wash the concrete with a mild dishwashing soap and water. Rinse away all soap residues. Allow the concrete to dry.

  • Cover any vents and under doorways with plastic sheeting and low-tack painter’s tape. Dust will seep through these openings if not properly sealed. Open as many windows as possible to provide ventilation.

  • Attach the appropriate sanding disk to the handheld grinder. A diamond pad is the more common name for a disk that will grind concrete. Every manufacturer will have a different naming system for their sanders. Use a disk that is indicated for grinding concrete. Put on protective eyewear to avoid particles damaging your eyes.

  • Turn on the handheld grinder and lower slowly to the concrete. Grind it in using a back and forth and up and down motion. Polish the entire surface until the shine is visible.

  • Vacuum the area to remove the majority of the sanding dust. Wipe the area with a wet towel to remove any small particles that were missed by the vacuum.
