How To Polish Concrete Countertops

How do you make concrete countertops smooth and shiny?

If you want to achieve an ultra-smooth, seamless surface, then polishing or sanding the concrete after it’s cast is the best approach. Polishing can also be used to expose decorative aggregate, glass, or stone within the concrete, resulting in terrazzo-like finishes.

How long should concrete countertops cure before polishing?

Allow the concrete countertop to cure for a minimum of 10 days before polishing. Concrete younger than that is still too soft to polish well, and concrete older than a month will be more difficult to polish and will use up more pads.

Polishing concrete countertops gives you a very smooth, hard, dense surface that’s easy to clean and maintain. There are a few different looks you can achieve when you polish a concrete countertop. You will also need wet diamond polishing pads from 50 grit to 3000 grit depending on the look you are trying to achieve.

Use the sandpaper with the right grit For perfect finish and smoothness, use superfine sandpaper with grit ranging between 200-400. If there are severe imperfections, then you need to use a floor grinder or special diamond disc. Always start with the coarsest sanding disc and then use a higher-grit disc.

Can I use an orbital sander to polish concrete?

The best and easiest way to sand concrete would be with a random orbital sander. This is because you can easily control the motion left to right or back and forth, whereas using a traditional palm sander, you’ll have to use different strokes for this motion.

How do you make concrete countertops smooth?

Can you sand concrete with a palm sander?

If you only have a small area to sand, you can also use a palm sander, orbital sander or belt sander. Rough imperfections may require the use of a special diamond disc and a concrete floor grinder.

Can you sand concrete to make it level?
