Answer :

It is important not to allow the slurry to dry on the concrete because it will harden in the concrete. For small areas, you can also use an orbital sander, a belt sander, or even a hand-held palm sander to sand them down. It may be necessary to use a special diamond disc in conjunction with a concrete floor grinder to smooth out rough imperfections.

In addition, what kind of tool is used to sand concrete?

Preparation of Concrete for Sanding If you have concrete that will be exposed architecturally, you can sand it by hand with wet and dry sandpaper or with an orbital sander, depending on your preference.

Also, is it possible to smooth concrete after it has dried?

There are two basic methods for smoothing out hardened concrete surfaces: mechanical and chemical. Dry grinding and wet rubbing are the methods used. Wet grinding is performed on dry concrete surfaces in order to remove fins and marks left by form work. The water, combined with the rubbing action, brings up a cement paste, which results in a surface that is extremely smooth and plaster-like in appearance.

As a result, one might wonder, how does one go about sanding a concrete floor by hand?

Concrete Scuffing and Sanding Techniques

What is the best way to hand sand concrete?

The quickest and most effective way to wet sand concrete that has been dry sanded and still has a cement-cream finish is to wet sand by hand with 320 to 400 grit silicon-carbide wet/dry sandpaper, as shown in the photo. The fact that silicon carbide is much harder than concrete means that it can easily abrade the surface without removing the cream finish.

An end user who wishes to remove half an inch of concrete from a 10,000-square-foot floor will not be satisfied with a low-speed surface grinder.

Is it possible to grind concrete to a smooth finish?

The wheel/disc should be moved quickly and smoothly across the surface of the concrete. Make several passes over a high point in order to grind it away.

What is the best way to sand a stained concrete floor?
