Removing Minor Surface Damage

Your solid surface acrylic bath is strong and durable, and will provide you with years of satisfaction. If you observe stains or minor scratches in the acrylic surface, follow these steps to quickly repair your bath.

IMPORTANT! This repair procedure is not appropriate for deep scratches, gouges, or chips. For damage of that nature please contact Kohler Co. or a local solid surface repair professional.

NOTE: We recommend wet sanding to extend the life of the sandpaper, although dry sanding will produce the same quality repair.

NOTE : Use 400 grit sandpaper to remove scratches and stains.

Apply flat, even pressure with the sandpaper and move the paper in a circular pattern.
Inspect your progress frequently to ensure a quality repair.
Clean or replace the sandpaper as needed during the repair.
When the damage is repaired, polish the area with clean 600 grit sandpaper. Use a steady circular motion to polish the repaired surface and surrounding area to restore the bath to its original finish.
When you are finished, rinse the bath surface with clean water to remove any sanding dust and debris. Use a clean cloth to dry the bath surface.
