In every case, how do you sand a concrete floor by hand? Attach 180-grit sandpaper, which is a fine grit, to a pole sander, hand sander or floor sander. Put on a respirator, and sand the entire surface of the floor lightly. When the sheen is off the surface, scuff sanding is complete.
Forbye, how do you smooth out concrete?
Can you sand concrete to make it smooth?
For smooth finishes and removing minor imperfections, use 80- to 120-grit sandpaper. For the smoothest finish use superfine sandpaper, 200- to 400-grit or higher. If you use a wet-dry sandpaper, you can wet the area before you work to keep dust down.
Yes, you may pour a concrete pad overlay over an existing slab. You need to consider the added height and weight of the overlay on the existing structure. Overlays may include polymers, portland cement concrete, or epoxies.
use steel finishing trowel for smooth texture To finish the concrete, use a steel finishing trowel to achieve a smooth texture. The tool brings water to the surface of the concrete. Don't use too much water, but at the time same time, work the tool to create a smooth finish.

A concrete finisher is a skilled tradesperson who works with concrete by placing, finishing, protecting and repairing concrete in engineering and construction projects. ... After levelling the concrete, they smooth the surface using either a hand trowel, a long handed bull float or by using powered floats.
To achieve a smooth and shiny concrete finish first requires proper leveling, floating, and troweling before it cures. After attaining a relatively smooth concrete surface, and once the concrete is dry, you can utilize either mechanical or chemical polishing methods to achieve a nice, glossy shine.
The Cure for Crumbling Concrete Steps As long as the steps are structurally sound—meaning, they're not spalling, flaking, or broken all the way through—you can repair most surface issues. ... If your patch is thicker, build the vinyl concrete patcher up in ¼ inch applications. (See this handy video for the technique.)
Apply Leveling Compound in Certain Spots Leveling compound is the classic and the easiest to fix a floor that is uneven. In fact, for some interior floors, it's just a matter of pouring leveling compound out and letting it find its own level. For garages, it is a little less simple.
Smooth it out best you can with a putty knife or margin trowel. Within 24 hours the repair will be hard enough to grind or sand flush. For larger areas of pitting and spalling, we recommend using a 100% epoxy concrete patch with a sand aggregate. The silica sand is mixed in with the epoxy to act as a filler.
