You can absolutely sand concrete to achieve a smoother surface. This method requires you to remove about 1/16th of an inch off the surface of the concrete. If you take this method a step further, you can achieve an exposed aggregate finish.

Can you grind concrete to level it?

If you have an uneven concrete slab, you could replace it or cover it with leveling compound. But consider grinding it instead. Powerful grinding equipment is available at rental centers that cater to contractors. Grinding down leftover thin-set or other hard coatings.

How do you make concrete smoother?

For a really smooth finish, repeat the troweling step two or three times, letting the concrete harden a bit between each pass. At first, hold the trowel almost flat, elevating the leading edge just enough to avoid gouging the surface. On each successive pass, lift the leading edge of the trowel a little more.

How do you smooth rough concrete edges?

For basic sanding, use sandpaper with the grit between 40-60. To remove minor irregularities, use 80-120 grit sandpaper. 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.

Why do diamonds grind in concrete?

Diamond grinding is a pavement preservation technique that corrects a variety of surface imperfections on both concrete and asphalt concrete pavements. Diamond grinding restores rideability by removing surface irregularities caused during construction or through repeated traffic loading over time.

Can I use a belt sander on concrete?

The belt grinder is used strictly for removing and grinding large amounts of concrete. These grinders are also hand-held. However, they are fitted with 60-grit sanding belts that spin at high speed.

Can I use an orbital sander on concrete?

Can I grind concrete with an angle grinder?

Although the various concrete cutting saw is available, an angle grinder is the most convenient tool for small concrete cutting work. A concrete-cutting blade for an angle grinder has a diamond-studded rim with ventilation grooves — a tile-cutting blade uses diamond studs but does not have the grooves.

How much can you grind down concrete?

A small planetary concrete grinder with basic grinding tools will remove around 1/16” of the concrete in 1-2 passes in a normal situation. You might be able to remove more – 1/8” if use a heavier concrete grinder and more aggressive PCD tools. In fact, an angle grinder with a cup wheel will do the best job.

Should you wet concrete while curing?

ANSWER: Keeping concrete moist helps the curing process. If too much water is lost from the concrete through evaporation, the hardening process slows down or ceases. Concrete continues to gain strength after pouring for as long as it retains moisture, but the longer it moist-cures, the slower the rate of strength gain.

How do you make a concrete floor smooth and shiny?

For this, you need to put a small amount of elbow grease on the area and sprinkle baking soda over it. Then use a damp cloth to rub around the area to make the area smooth and shiny again.
