How to Polish a Concrete Floor With a Handheld Grinder

Polished concrete is durable and attractive. Polished concrete is also a terrific way to update your home without a lot of expense. You could hire a contractor to come to your your home, make a big mess and charge you a fortune to bring out the shine in your concrete floors. Or you can get the job done yourself with a lot less hassle and expense. A small section of concrete can be polished with a hand sander.

You can't beat the look of polished concrete.

Step 1

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.

Step 2

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.

Step 3

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.

Step 4

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.

Step 5

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.
