How to Polish Concrete Counters
If you’ve decided to put polished concrete counters in your home, it’s fairly easy to polish them and get them looking as if you just had them installed.
What You Will Need:
- Various polisher pads (50 grit to 800 grit)
- Hand held concrete polisher
- Spray bottle of water
- Heavy apron
- Eye protection
- Damp sponge
- Concrete sealant
- Make sure that you have appropriate protective gear on, including a heavy apron and eye protection. This process will kick up a lot of concrete dust and you need to make sure that you keep yourself protected. Debris in the eyes can cause some major damage, so even if you wear glasses, goggles are recommended. Note: Steps 2 and 3 are optional if you do not want to expose your aggregate for a full polish. If you have decided that you just want to polish the top, go ahead and skip these steps and go to step 4.
- Take your polisher and start with the 50 grit polisher pad. You will start to remove the top layer of concrete and expose the aggregate. During this whole process, you want to be spraying the countertop. This will help to keep your polisher pads from getting too hot and becoming worn down and/or damaged. Note: In between each step, you’ll want to wipe off the counter space with the wet sponge. This will help to get rid of dirty water,
- Continue polishing the concrete counter tops, using almost every grit pad you have in your kit, increasing the grit slowly (100 grit, 150 grit…) until you reach the 400 grit pads. As mentioned in step 2, continue using your spray bottle to keep the surface wet and to protect your polishing tool.
- Switch your polish setting, and instead of exposing, you want to start polishing the surface of the countertop with the 400 grit pads. This is your first step if you decided to skip exposing the aggregate.
- Go up to the 600 and 800 grit polish pads. The 800 grit will help create a smooth, glassy appearance that you started this process for.
- Take the sponge and some clean water to clean off the countertop, which will help to get rid of any of the excess debris from polishing.
- Once your countertop is dry, apply a sealant to help obtain the glassy appearance and to help protect your countertop from staining.
