How to Paint Metal Filing Cabinet Rustoleum

Supplies Needed

• Rustoleum spray paint in your desired color(s)
• Cleaning supplies like soap and water, degreaser, rags
• Sandpaper – 120 and 220 grit recommended
• Tack cloth
• Painter’s tape
• Drop cloths or newspaper
• Face mask
• Disposable gloves and protective eyewear

Preparing the Filing Cabinet

Proper preparation is crucial for the paint to adhere correctly and achieve a smooth finish.

Clean the Surface

Make sure the filing cabinet is free of dirt, oil, and grease. Scrub it down using a degreaser or soap and water solution. Rinse and let dry fully.

Sand the Metal

Lightly scuff sand to rough up the surface so the paint can grip better. Use 120 grit sandpaper to get rid of any rust spots, chipped paint or flakes. Then smooth it out with 220 grit.

Be sure to sand in the direction of the metal grain and thoroughly wipe away all sanding residue with a tack cloth when finished.

Mask Off Areas

Use painter’s tape to cover any hinges, hardware or areas you don’t want accidentally painted. Tape off the edges for a crisp paint line.

Place Drop Cloths

Lay down plastic drop cloths or newspapers below your workspace to protect surrounding surfaces from drips and overspray.

Painting the Cabinet

Follow the steps below to spray paint your filing cabinet properly:

Shake the Can

Make sure to shake the Rustoleum spray paint vigorously for at least one full minute. This mixes the paint pigments and ensures even coverage.

Spray Paint in Light Coats

Hold the can 6-8 inches from the surface and spray in even, overlapping strokes. Apply 2-3 thin coats instead of one thick coat, allowing 5-10 minutes of drying time between coats.

Thin coats prevent drips and runs in the paint. Be patient and allow each coat to dry fully before adding another.

Start and Finish Spraying Off the Cabinet

Start spraying off the piece in a quick sweeping motion to prevent excess paint buildup on the edges. Finish each coat in the same manner.

Paint All Sides

Don’t forget the cabinet top, sides and back. Fully coat all exterior surfaces for complete protection and an uniform look.

Remove Tape Promptly

Carefully peel off any masking tape immediately after the final coat before the paint dries. Pull slowly at a 45° angle to avoid chipping the paint edges.

Dry and Cure

It takes about 24 hours for Rustoleum spray paint to be dry to the touch on metal furniture. The curing process can take 2-4 weeks before the paint fully hardens and becomes chip resistant.

Avoid heavy use during this time. Allow 1-2 weeks curing before placing heavy items back inside the painted filing cabinet. The paint will continue to strengthen over time.

Tips for Best Results

• Always read and follow the directions on the spray paint can for proper application.
• Avoid painting in very windy, humid or cold conditions.
• Use steady back and forth strokes about 8 inches from the surface.
• Multiple light coats provide better coverage than a single heavy coat.
• Be patient and allow proper drying time between coats.
• Sand glossy surfaces lightly before painting for better adhesion.
• Apply a clear sealer spray if desired for added protection.

Painting metal filing cabinets is an easy DIY project using Rustoleum spray paint. Just be sure to properly prepare the surface and apply thin even coats. With a little time and effort, you can give old metal cabinets an attractive updated look!
