MAINTENANCE AND REPAIR
DUCHEM products will not stain and are resistant to most abrasive chemicals. Periodic cleaning with a 70% ethyl alcohol solution is recommended (other waxes or coatings should not be applied). DUCHEM worktops can suffer damage however through abuse or neglect. Scratches and marks can usually be prepared in the field using the following materials and procedure:
Material required:
• Oil (mineral or light machine oil)
• Silicone Carbide Sandpaper (grits 80, 120 and 220)
• 3M Scotch Brite (or equivalent)
• Clean cloths
Depending on field conditions, either hand-tools or power-tools may be used to repair scratches.
Procedure:
Apply oil to the area to be repaired, then begin sanding with 80 grit sandpaper in the same direction as the scratch using a moderate to light touch until scratch disappears. The lighter the pressure, the less material is removed, and the better the repair will look.
The final sanding should be done using 220 grit paper and oil. Again, work in the same direction as the scratch using a light touch. Use plenty of oil to remove sanding marks from the work surface. Buff the sanded area with oil and 3M Scotch Brite until you are satisfied with the result. Buff further with clear rags and the repair is complete.
