Techniques for Smoothing Concrete Surfaces with a Hand Held Grinder

If you’re looking to smooth out your concrete surfaces, these techniques using a portable grinder will do the trick without breaking the bank.

First, start by selecting the right grinder and grinding wheel based on the job at hand. For larger surfaces, a grinder with a larger disc size will be more efficient, while smaller surfaces can be tackled with a smaller disc. The grinding wheel should also be chosen based on the surface type and desired finish. A diamond grinding wheel is best for smoothing out rough surfaces, while a silicon carbide wheel is better suited for finishing and polishing.

Before starting, make sure to wear all necessary safety gear, including eye and ear protection, gloves, and a respirator.

Begin by holding the grinder with both hands and gently lowering it onto the surface, letting the weight of the tool do most of the work. Move the grinder back and forth in a smooth, even motion, using overlapping passes to ensure even grinding. Keep the grinder moving at all times to avoid creating uneven spots or gouges in the surface.

Once the surface is smooth, switch to a finer grit grinding wheel and repeat the process to achieve the desired finish.

After finishing, thoroughly clean the area to remove any dust or debris left behind by the grinding process.

With these simple techniques and proper safety precautions, you can achieve a smooth and polished concrete surface with a hand held grinder.

Removing Old Paint or Glue with a Hand Held Concrete Grinder
