How to Refinish a Metal File Cabinet

Refinishing a metal file cabinet can give it a fresh, updated look while also extending its life. With some simple steps and supplies, you can transform a worn-down cabinet into one that looks brand new. This guide will walk you through everything you need to know to refinish a metal file cabinet.

Assessing the File Cabinet and Planning the Refinishing

Before you begin refinishing, take some time to assess the current state of the file cabinet and plan out the refinishing process.

Evaluate the Condition of the Cabinet

Carefully look over the entire cabinet, inside and out, to identify any problem areas or damage. Check for:

• Rust or corrosion
• Dents, chips, or scratches in the metal
• Peeling or cracked paint
• Warping or other structural damage

Make notes on the condition to help plan your approach.

Choose a Location

Pick a well-ventilated area like a garage or backyard to do the refinishing work. Lay down tarps or drop cloths to protect surrounding surfaces from paint drips. You’ll also need easy access to water.

Remove Contents and Hardware

Empty out the file cabinet completely and remove any existing hardware, including rails, handles, and locks. Place hardware together so it can be reinstalled later.

Clean the Cabinet

Use a degreaser or mild soap and water to thoroughly clean the interior and exterior of the file cabinet. This removes built-up grime and prepares the surface for painting. Pay extra attention to rust spots.

Gather Supplies

You’ll need:

• Metal primer spray paint
• Metal paint spray paint in your finish color(s)
• Fine grit sandpaper
• Rags
• Painter’s tape
• Painters plastic or drop cloths

Optional supplies include filler, wood putty, or rust converter if repairs are needed.

Make Any Repairs

Use sandpaper to smooth any rough areas on the cabinet. If there are scratches, dents, or holes, you can fill these with metal filler, wood filler, orspot putty before painting. Take care of any rust issues with a rust converter.

Sand Surfaces

Lightly sand all interior and exterior surfaces to rough them up and help the paint adhere. Wipe away any dust.

Mask Off Areas

Use painters tape to mask off any areas you don’t want painted, like glass windowpanes or the interior of drawers. Remove hardware like handles and hinges.

Priming and Painting the Cabinet

With the prep work done, you’re ready to apply primer and paint.

Apply Primer

Use spray primer formulated specifically for metal surfaces. Shake the can vigorously and spray in light, even coats. Let the primer dry fully before moving on.

Add Paint in Thin Coats

Carefully read and follow the directions on the spray paint can. Shake well before using. Keep the can 6-10 inches from the cabinet as you spray in thin, even coats. Let each coat dry completely before adding another.

Paint the Interior

Once the exterior painting is complete, mask off the exterior with painters tape and plastic to paint the interior drawers and storage areas. Use the same process of applying thin, even coats.

Consider a Second Coat of Paint

For best results, apply two coats of spray paint to the cabinet exterior and interior. The second coat helps ensure full, even coverage.

Remove Masking and Reinstall Hardware

After the final coat of paint has dried, carefully remove any masking from glass or drawers. Reinstall handles, locks, and other hardware.

Tips for a Smooth Paint Job

Follow these tips as you refinish for best results:

• Work in a dust-free area to avoid particles sticking to the wet paint.
• Avoid painting in direct sunlight or high heat which can cause paint to dry too fast.
• Use slow, steady motions with the paint sprayer to avoid drips or uneven coverage.
• Give each coat time to fully dry before adding another – usually 1-2 hours.
• Gently sand paint between coats using fine 400 grit sandpaper to help smooth and remove any drips.
• Apply thin coats of paint rather than one thick coat for a smoother finish.
• Read the manufacturer’s directions – some specific spray paint brands or finishes have special requirements.

Finishing Touches

Once the cabinet is fully painted, give it a day or two to cure before putting it back into use. Then add any finishing touches:

• Carefully move the cabinet back into place and anchor to wall if needed.
• Reinstall doors, drawers, and hardware. Make any needed adjustments.
• Touch up paint if any new nicks or scratches occurred during reassembly.
• Consider adding new drawer pulls or knobs to give an updated look.
• Stock the cabinet with office supplies or other organizers.

Maintaining the Refinished Cabinet

To keep your refinished file cabinet looking fresh, do the following:

• Use felt pads under any items placed on top of the cabinet to prevent scratches.
• Dust regularly with a microfiber cloth.
• Avoid letting any liquids sit on the surface to prevent stains.
• Wipe up spills immediately with a soft cloth. Avoid harsh cleaners.
• Consider applying a paste wax once or twice a year to protect the finish.
• Avoid placing in direct sunlight which can cause fading over time.

With proper prep and painting techniques, your refinished file cabinet can look amazing and last for years to come. Take your time with each step for best results. The effort is well worth it when you see the transformation. Enjoy the finished product!
