How to Spray Paint a Metal Filing Cabinet

Spray painting a metal filing cabinet can seem daunting, but with the right preparation and techniques, it can be a relatively easy DIY project that allows you to customize your space. Here is a comprehensive guide on how to properly spray paint a metal filing cabinet to get professional-looking results.

What You’ll Need

  • Paint sprayer or paint spray cans
  • Paint – spray paint formulated for metal works best
  • 220 to 320 grit sandpaper
  • Tack cloth
  • Painter’s tape
  • Drop cloth
  • Nitrile gloves & respirator mask

Step-by-Step Guide

Clean the Filing Cabinet

The first step is to thoroughly clean the filing cabinet to remove any dirt, grease, or grime. This allows the paint to properly adhere to the metal surface. Use a degreasing cleaner and scrub with a scouring pad and rinse.

Sand the Surface

Lightly scuff sand the entire cabinet using 220 to 320 grit sandpaper. This helps the paint bond to the metal. Focus on any rust spots, smoothing them out before painting. Wipe clean with a tack cloth after sanding to remove any dust.

Tape Off Areas

Use painter’s tape to mask off any areas you don’t want painted, such as the interior of the drawers or cabinet. Remove the drawers and set aside during the painting process.

Apply Primer

Optionally apply 1-2 coats of a metal primer before painting for maximum adhesion and rust prevention. Allow each coat to fully dry.

Spray the Paint

Working in a well ventilated area, shake the spray paint can vigorously for 1 minute. Hold the can 10-14 inches from the surface and spray using light, even strokes. Apply 2-3 thin coats rather than one thick coat, allowing 10 minutes of dry time between coats. Mist on the final coat to achieve a smooth finish.

Remove Tape and Reattach Hardware

Once the final coat is dry, carefully remove the painters tape. Reattach any handles or hardware that were removed using a screwdriver.

Allow Paint to Cure

Let the paint cure for at least 24 hours before use. Avoid closing the drawers or putting any weight on the cabinets during this time.

Apply Clear Coat (Optional)

For extra protection and sheen, apply 1-2 light coats of a clear enamel spray paint after the paint has cured.

And that’s it! With proper preparation and techniques, DIY spray painted filing cabinets can look professionally painted. Just be sure to use short, light spray strokes and multiple thin coats of paint. The finished result is a customized filing cabinet that matches your home décor.

Frequently Asked Questions

What type of spray paint is best for metal?

The best spray paint for metal is one specifically formulated for use on metal surfaces. Look for labels indicating “metal”, “rust-oleum” or specifically for use on filing cabinets. Enamel-based spray paints provide the most durable finish.

How do I avoid brush strokes when spray painting?

To avoid brush strokes, hold the can 10-14 inches from the surface and use light, even sweeping motions. Mist on final coats to achieve a flawless finish. Avoid applying too much paint in one area.

What grit sandpaper should be used to prep metal?

Use a 220 to 320 grit sandpaper when sanding metal filing cabinets prior to painting. This provides enough tooth for the paint to bond properly. Make sure to wipe away dust with a tack cloth when done.

Can you spray paint a filing cabinet without sanding?

Lightly sanding first is highly recommended so the paint properly adheres. While you can spray right onto the metal, skipping sanding risks chipping, peeling or the paint rubbing off over time.

How long does spray paint take to dry on metal?

Spray paint will be dry to the touch in about 10 minutes on metal surfaces. Allow 1-2 hours between coats, and let the final coat cure for 24 hours before use. Applying clear coat extends the curing time.

What precautions should I take when spray painting?

Paint outdoors or in a well ventilated area. Wear gloves, goggles, and a respirator mask. Cover nearby surfaces with a drop cloth. Follow the usage directions on the spray paint can.

Conclusion

Spray painting metal filing cabinets is a relatively simple process that allows you to customize your home office. With the proper preparation, materials, and spray painting technique, you can achieve flawless, professional-looking results. The key steps include thoroughly cleaning the cabinets, light sanding, applying 2-3 thin coats of spray paint formulated for metal, allowing proper drying times between coats, and giving the final paint job 24 hours to cure before regular use. With a DIY spray painted filing cabinet, you can inexpensively match your office decor or give old cabinets new life.
