Follow this guide to prep, paint, and protect a metal filing cabinet for a stylish and durable finish.

Gather the Necessary Supplies

Repainting metal requires specific supplies designed to adhere to slick surfaces and withstand wear and tear. Be sure you have the following materials before starting:

• High-quality metal primer – Primer helps the topcoat of paint bond tightly to metal. Look for primier formulated especially for metal or galvanized steel.
• Exterior paint – Exterior or outdoor paint stands up to abrasion better than interior paints. Choose a finish like satin or semi-gloss for best durability.
• Fine grit sandpaper – Lightly sanding helps paint adhere to smooth metal. Grab a multipack of fine 120-220 grit sandpaper.
• Small foam paint rollers and angled paintbrushes – Rollers and brushes sized for trim and edges are ideal for cabinets.
• Painters tape – For covering hardware and lining off edges. Blue tape for delicate surfaces works best.
• Drop cloths – Sheets of canvas or plastic to protect floors and furniture from drips.
• Paint thinner – For cleanup of oil-based paints. Check the paint can’s label to see if thinner is needed.
• Rags – Old t-shirts or soft cloths for wiping away paint drips.

Collect all materials before starting to make the painting process fast and efficient.

Prepare the Metal Cabinet for Painting

Proper prep is crucial for getting paint to adhere evenly and permanently to slick metal. Follow these key steps:

Clean the Surface

Wipe down the entire cabinet using a grease-cutting cleaner or solution of dish soap and water. Rinse thoroughly and let dry fully. Remove any lingering grease, dirt, or residue so paint can stick.

Lightly Sand

Use 120-220 grit sandpaper to scuff up the surface. This helps the primer and paint grab onto the metal. Be sure to sand every area that will be painted, including the body, drawers, and doors.

Remove Hardware

Unscrew door and drawer handles and pulls using a screw driver. Place hardware in a plastic bag and set aside to reattach after painting. Cover the holes with painters tape.

Tape Off Areas

Use painters tape to mask off any areas you don’t want painted, like cabinet joints or edges. This keeps drips limited to surfaces getting a new coat.

Wipe Clean

Give the sanded cabinet a final wiping with a tack cloth or rag dampened with paint thinner to remove any dust. Let dry fully before priming.

Thorough prep should leave every surface dull and lightly abraded. The cabinet is now ready for primer and paint.

Apply Primer and Paint

With the right products and techniques, it’s straightforward to apply a smooth, even finish. Follow this process:

Prime All Areas

Use a foam roller or brush to apply a uniform coat of metal primer to the cabinet. Cover all sides – front, back, top, sides, doors, and drawers. Let the primer dry fully before painting.

Paint Using Thin Coats

Apply paint in thin, even coats using a small foam roller and angled trim brush. Waiting 2-4 hours between coats allows proper drying time. Too much paint at once can drip or bubble.

Paint Doors Separately

Paint cabinet doors, shelves, and drawers outside of the cabinet, laying them flat on dropcloths. This prevents drips and allows easy access to all sides.

Allow Proper Dry Time

Let the final coat dry fully for 24-48 hours before reattaching doors and handles. Drying too quickly can affect durability.

Check Coverage

Inspect for any missed spots and do touch ups with primer and paint as needed. Closely examine edges and hardware holes.

Careful application results in professional-looking, consistent coverage from top to bottom.

Reattach Hardware and Seal Paint

The finishing touches involve reassembly and an extra layer of protection:

Screw Hardware Back In Place

Carefully realign and attach any door pulls, handles, hinges or sliding mechanisms removed before painting.

Seal with Clear Polyurethane

For added durability, apply 1-2 thin coats of clear satin or semi-gloss polyurethane. This protective topcoat resists scuffs, stains, and wear.

Remove Tape

Once paint has fully cured in 1-2 weeks, gently peel away any painters tape used during the process.

With hardware reattached and a sealant added, the filing cabinet has a refreshed yet functional finish ready to organize office paperwork.

Tips for a Professional Paint Job

Follow these pointers for getting an expert-level paint job on metal cabinets:

• Choose exterior paint for the toughest finish – it stands up to wear and tear better than indoor paint.
• Thoroughly mix paint before and during application to ensure consistent color and coverage.
• Keep paint can rims and caps clean between uses for an airtight seal to prevent drying out.
• Maintain a wet edge during painting by working systematically from one end to the other and completing full sections at a time.
• Work in the shade and avoid painting in direct sun or on hot metal to prevent bubbly paint that dries too quickly.
• Apply paint with the grain of the metal using long, straight strokes for the smoothest results.
• Use an angled trim brush to cut in edges and corners before rolling larger areas.
• Allow for proper drying time between coats – fully cured paint means durable paint.

With focus, care, and the right supplies, you can achieve professional results repainting a metal filing cabinet. The freshly painted piece will look cohesive in your office décor while improving organization and storage.
