How to Sand Durabond 90: Things You’ll Need

Wear Safety Gear

Take a dust mask and place it over your nose and mouth. Make sure to secure it tightly to ensure it fits snugly, covering your nose and mouth completely.

Put on safety goggles to protect your eyes from airborne dust particles and other debris. Ensure the goggles sit firmly against your face to prevent dust from getting in.

Test the Surface

Run your fingers lightly over the Durabond 90-covered surface. You’re looking for any inconsistencies, bumps, or ridges that will need sanding down.

Make mental or physical notes (e.g., with masking tape) to mark the areas that feel uneven or rough. These will be your focus points when you begin sanding.

Start with Corners

Hold the sanding sponge so that one of its edges can easily reach into corners and along edges. Apply moderate pressure to the sponge and make short, controlled strokes in the corners. Ensure you are sanding in the direction perpendicular to the edge to get an even finish. Pay attention to the amount of pressure you apply to avoid removing too much material.

Flat Areas

Wrap a piece of medium-grit sandpaper around the flat face of the sanding sponge. Place the sponge against the flat area you wish to sand.

Move the sponge in a circular motion, applying consistent moderate pressure. Make sure to overlap your circles to ensure an even finish. Regularly check the surface and your sandpaper. If the sandpaper becomes clogged with material, replace it to maintain effectiveness.


Attach the brush attachment to the vacuum cleaner. Turn the vacuum cleaner on and gently run the brush over the entire surface you’ve sanded. Make sure to get into the corners and along the edges where dust is likely to accumulate. After vacuuming, inspect the surface to make sure all the dust and debris have been removed.


Gently run your hand over the sanded surface once again to feel for any remaining imperfections. If you find any uneven spots, bumps, or rough patches, go back and repeat the sanding process for those specific areas. Ensure that the surface feels smooth to the touch before declaring the job complete.
