Selecting the Right Sanding Equipment
The tools you’ll need for sanding a concrete garage floor include:
– Sandpaper: Depending on the condition of the floor, you may need coarse, medium, and fine-grit sandpaper.
– Sanding block: A sanding block helps you maintain a consistent pressure and angle while sanding.
– Dust mask: Sanding concrete can produce a significant amount of dust, so wearing a dust mask is essential for your health.
– Safety goggles: To protect your eyes from any debris that may fly up during the sanding process.
– Broom or vacuum: To clean up the dust after sanding.
The Sanding Process
1. Start by sanding the floor with coarse-grit sandpaper to remove any large imperfections, such as cracks or rough spots.
2. Switch to medium-grit sandpaper and continue sanding the entire floor, paying close attention to areas with deeper imperfections.
3. Once the floor is smooth, switch to fine-grit sandpaper to achieve a smooth, even finish.

5. After sanding, clean the floor with a broom or vacuum to remove any remaining dust.
Finishing Touches
Once the sanding process is complete, inspect the floor for any remaining imperfections. If necessary, use a putty knife to fill in any small cracks or holes. Allow the floor to dry completely before applying a new coat of paint or sealant.
