Can You Use A Belt Sander On Concrete

Yes, you can use a belt sander on concrete. Several types of sanders can grind or sand concrete surfaces. For instance, a belt sander can aggressively grind down concrete, while a conventional orbital sander can smooth and level a concrete surface.

In addition, you can shape a concrete surface by removing layers of concrete using an angle grinder or grinding wheel. When sanding or grinding concrete surfaces, use proper safety gear, such as safety glasses, eye protection, dust masks, and hearing protection. Read the instructions before using the equipment and take the necessary measures to ensure you operate it safely.

How to sand concrete and what kind of equipment is needed?

Concrete Preparation for Sanding: Depending on your taste, you can use an orbital sander or wet and dry sandpaper to sand concrete that will be exposed architecturally.

Can Concrete Be Smooth After It Has Dried Too?

Surfaces of hardened concrete can be rounded off by mechanical or chemical means. The techniques employed are wet rubbing and dry grinding. Fins and markings left by concrete forms are eliminated by wet grinding on dry concrete surfaces. The surface is incredibly smooth and plaster-like due to the water and rubbing action raising a cement paste.

You may, therefore, be asking how to sand a concrete floor manually.

Concrete Sanding and Scuffing Methods

• Add a few drops of dish soap to a pail of warm water and swirl thoroughly.

• Covering windows and doorways with plastic sheeting may prevent dust from entering other rooms in the house.

• To complete the task, attach the fine grit of 180-grit sandpaper to the end of a pole sander, hand sander, or floor sander.

• It removed the floor dust with a second pail of water that contained dish soap.

How Should Concrete Be Hand-Sanded?

Concrete that has been dry sanded and still has a cement-cream surface can be wet sanded quickly and efficiently by hand using 320–400 grit silicon–carbide wet/dry sandpaper, as seen in the photo. Silicon carbide may easily abrade the surface without destroying the cream finish because it is much tougher than concrete.

CHOOSE A GRIT

Decide on the grit of your sandpaper, if necessary, once you've chosen the tool you'll be utilizing. You should seek 800 grains or greater for the straightforward task of polishing concrete because the higher the grit of the sandpaper, the finer the finish. You'll probably need sandpaper with a 40- to 60-grit rating to remove pockets. You might need several different types of paper to get the desired result.

Factors To Consider While Sanding Concrete With Belt Sander

Here are the following factors to keep in mind while sanding concrete with a belt sander:

• Aggressive Nature: Belt sanders are aggressive. They are designed to remove material quickly from concrete. It helps level uneven surfaces but can also create grooves if not used properly. 

• Dust Generation: Belt sanders can create major dust while sanding concrete, which is harmful to the operator’s health. Always make sure to wear appropriate respirators or safety gear during the sanding process.

• Sanding effects: Belt sanders generate visible sanding marks on the surface. Hence, it is not suitable for a smooth and fine finish. 

• Be cautious: Always take safety precautions while sanding concrete. Always wear appropriate safety gear and follow the user manual for more safety. Additionally, you can practice on scrap pieces of concrete to get an idea of how the belt sander works, preventing mistakes on your actual workpiece.
