How to Refinish Metal File Cabinet

Refinishing a metal file cabinet can breathe new life into an old piece of office furniture. With some simple cleaning, sanding, priming, and painting, you can give your filing cabinet a fresh, updated look. Here is a step-by-step guide on how to refinish a metal file cabinet.

Supplies Needed

• Sandpaper (120, 220 grit)
• Primer (spray or liquid)
• Paint (spray or liquid enameled paint)
• Paintbrushes
• Clean rags
• Tack cloth
• Drop cloth
• Painters tape
• Gloves & eye protection

Steps to Refinish a Metal File Cabinet

Clean the Cabinet

The first step is to thoroughly clean the filing cabinet to remove any dirt, grease, or oil. This will help the new paint adhere properly.

• Remove all drawers from the cabinet.
• Use a degreaser or soap and water to clean all surfaces of the cabinet and drawers.
• Pay close attention to handles, edges and corners.
• Rinse with clean water and let dry completely.

Sand the Cabinet

Next, use 120 grit sandpaper to scuff up the original paint on the metal cabinet and drawers. This helps the primer and new paint bond.

• Lightly sand all surfaces, including the interior of drawers.
• Use 220 grit sandpaper for a final sanding to smooth everything out.
• Wipe away all sanding dust with a tack cloth.

Apply Primer

Priming provides an important base layer for the new paint.

• For spray primer: Lay down drop cloths and tape off any areas you don’t want sprayed. Follow directions on the can for best results. Apply 2-3 thin coats.
• For liquid primer: Use a small paintbrush to apply inside drawers and corners. Use a roller for large flat surfaces on the cabinet exterior. Allow proper drying time between coats.

Paint the Cabinet

Now you’re ready for the fun part – choosing a new color! For best results on a metal filing cabinet:

• Use a quality enameled paint formulated for metal. Choose a semi-gloss or high gloss sheen.
• Follow all directions on the paint can for best application and results.
• Apply thin, even coats and allow proper drying time between coats.
• Use smooth motions with spray paint or a foam roller for the large exterior surfaces.
• Use small foam brush for inside drawers and edges.
• Apply 2-3 coats for best coverage and durability.

Replace Hardware

Once the paint is fully cured, put the drawers back in the freshly painted cabinet. Consider replacing old hardware with new handles and knobs to finish off your “new” filing cabinet.

Tips for Best Results

• Properly prep and clean the cabinet – this is key to good adhesion.
• Apply primer before painting for a smooth finished look.
• Use quality enameled paint designed for metal.
• Allow proper dry time between coats.
• Gently sand between coats for a super smooth finish.
• Work in a well-ventilated area.
• Be patient – slow and steady yields the best outcome.

With some elbow grease and these simple steps, you can give dull old metal filing cabinets new life! The right prep work and paint can transform it into a brightly colored or professionally finished piece. Refinishing is an affordable way to update office decor without having to buy brand new furniture.

Frequently Asked Questions

What type of paint should I use to refinish a metal filing cabinet?

For best results, use a quality enameled paint made specifically for metal surfaces. Be sure to choose a product that offers good adhesion and a hard, durable finish. Spray paint or liquid paint both work well. A semi-gloss or high gloss sheen is best.

What do I do if the original paint won’t come off?

If the original factory finish just won’t budge, try gently roughing up the surface with 150-220 grit sandpaper. Focus on scuffing it up rather than completely removing the old paint. Then, apply a high-quality primer before spraying on the new color. The primer will help the new paint adhere.

Should I remove the drawers before painting?

Yes, removing all the drawers allows you to fully clean, sand, prime and paint the cabinet interior, exterior, edges and sides. It also allows you to spray paint if desired without overspray getting inside. Replacing the drawers after the paint is cured finishes the job.

How do I avoid brush marks when painting?

Use high quality primer and paint along with good technique. Apply in thin, even coats using smooth brush strokes. Use a small foam roller for large flat surfaces and a tapered foam brush for details and edges. Allow proper drying time between coats. Gently sanding between coats also eliminates brush marks.

How long does it take for the paint to cure?

Most enameled paints take 24-48 hours to fully cure and harden. Avoid heavy use during this time. Check the product directions as drying times can vary. Achieving the hardest, most durable finish requires allowing the full curing time before use.

What precautions should I take when spraying paint?

When using spray paint, be sure to lay down drop cloths or tarps and tape off, cover or mask any areas you want to protect from overspray. Work in a well-ventilated area and wear an organic vapor respirator mask. Follow all safety precautions on the spray paint can.

Conclusion

Refinishing old metal filing cabinets is a relatively simple DIY project with big payoff. The right prep work and painting techniques will result in a gorgeously updated piece ready to store files in style. Just be sure to use the proper metal-specific paint products, prime first, allow adequate drying time, and work in thin coats. With a little time and effort, you can extend the life of office furniture and give it a fresh new look.
