Using a bush hammer on concrete floors is an effective way to prepare surfaces for coatings, overlays, or polishing. This guide explains the correct steps to use a bush hammer, ensuring maximum tool life and an even surface texture.
Use a bush hammer when you need to:
Select a bush hammer plate that matches your grinder or floor machine. Make sure the arbor size and rotation direction are compatible. For small areas, angle grinders work well; for large surfaces, use a walk-behind grinder.
Ensure the concrete floor is clean, dry, and free of debris. If using the wet method, spray a light mist of water before grinding to reduce dust and extend tool life.
Operate the machine under 1000 RPM to avoid overheating or damaging the tool. Slower speeds offer better control and a more uniform finish.
Do not press down hard. Let the bush hammer teeth do the work. Excessive pressure may wear out the teeth quickly or cause uneven marks.
Move steadily across the floor in overlapping rows, similar to mowing a lawn. Avoid staying in one spot too long.
Bush hammers are excellent for producing CSP 3–5 profiles, which are commonly recommended by coating manufacturers for epoxy and resin applications.
After each job, inspect the hammer heads for wear. Clean the plate thoroughly to remove debris and store in a dry area to prevent rust.
Water is optional. Wet grinding reduces dust and increases tool life, but ensure the floor is completely dry before applying coatings.
Yes, but it's important to use a dust collection system or the wet method to minimize dust exposure.
With proper use—low RPM, light pressure, and clean surfaces—a quality bush hammer can cover hundreds of square meters before replacement is needed.
