Can You Spray Paint a Metal File Cabinet?

Painting a metal file cabinet can help refresh its look and help it blend in with your home or office décor. With the right preparation and paint, spray painting a metal file cabinet is definitely doable for the DIYer. Here are some tips on how to spray paint a metal filing cabinet successfully.

Cleaning and Preparing the Cabinet

Proper preparation is key to achieving an even, durable spray painted finish on your metal filing cabinet. Follow these steps:

• Remove the drawers from the cabinet. This makes the cabinet easier to maneuver and provides better access for cleaning and painting.
• Clean the cabinet thoroughly with a degreasing agent like TSP substitute or mineral spirits. This removes any grease, dirt, or grime.
• Sand the cabinet lightly with 120-220 grit sandpaper. This helps the paint adhere better to the surface.
• Wipe off any residue and dust from sanding. Tack cloth works well for this.
• Fill any holes, scratches or dents with metal filler, then sand smooth.
• Mask off any areas you don’t want painted, like hinges and interior surfaces. Use painters tape and paper for best results.

Choosing the Right Metal Paint

For best results on a metal filing cabinet, choose a direct to metal (DTM) spray paint. These are formulated to bond tightly to metal surfaces without a primer. Some top options include:

• Rustoleum Professional High Performance Enamel
• Krylon Dual Superbond Paint + Primer
• Krylon SHORT CUTS Multi-Purpose Spray Paint
• Montana Cans MTN 94 Spray Paint

Avoid standard spray paints, which may not adhere well without a primer. An epoxy spray paint is another good option as it dries to a hard, protective finish.

Spray Painting Techniques

Follow these tips as you spray paint:

• Shake the can vigorously for 1-2 minutes before starting. This mixes the paint properly.
• Hold the can 6-8 inches from the surface. Get the right distance for full, even coverage.
• Use smooth, even strokes and maintain the same distance as you spray.
• Apply multiple thin coats rather than one thick coat. 2-3 coats is ideal for coverage.
• Allow proper drying time between coats according to the manufacturer’s directions.
• Add your coats slowly in different directions – up and down, side to side, etc.
• Watch out for drips and runs by applying light coats.
• For best protection, finish with a clear enamel spray paint over your color coats.

Maintaining the Finish

Once fully cured, a spray painted metal filing cabinet should hold up well to regular use with some care. Here are tips for maintaining the painted finish:

• Allow the paint to cure fully, which can take 1-2 weeks. Avoid heavy use during this time.
• Clean occasionally with a soft cloth and mild cleaner. Avoid harsh chemicals.
• Be gentle opening and closing drawers to avoid scratching.
• Place felt pads under any items placed on the top to prevent scratches.
• Avoid setting very hot items on the painted surface.
• Touch up any nicks/scratches quickly to avoid corrosion.

Tips for Success Spray Painting a File Cabinet

• Paint when temperatures are between 50-90°F and humidity is low for best results.
• Work in a well-ventilated area and wear a respirator.
• Cover nearby surfaces to avoid overspray.
• Use high quality spray paint and allow proper dry times.
• Prep the surface thoroughly – this is key for good adhesion.
• Apply multiple light coats rather than one thick, heavy coat.
• Be patient. Rushing the job can ruin the finish.

Spray painting a metal file cabinet takes some time and effort, but following these tips will help you get a smooth, professional looking finish that revives your cabinet. The best part is you save money compared to buying a new cabinet or having it professionally painted. With the right prep and paint, you can definitely DIY it.

Frequently Asked Questions About Spray Painting a Metal File Cabinet

Do you have to sand metal before spray painting?

Lightly sanding with 120-220 grit sandpaper is recommended before spray painting metal. This helps the paint adhere better by giving it a rougher surface to grip. Be sure to wipe away dust after sanding.

2-3 thin, even coats of DTM spray paint are recommended for full coverage on a metal cabinet. Allow proper drying time between coats. More coats may be needed for dark colors over light metal.

This depends on personal preference. Glossy paint is more durable and easier to clean. Matte is more modern and hides imperfections well. Consider a satin finish for a compromise between the two.
