How to Paint a Metal Filing Cabinet

Painting a metal filing cabinet can completely transform the look of your office or workspace. With some simple preparation, high-quality paint, and proper technique, you can give your old filing cabinets a fresh new look. Here is a comprehensive guide on how to properly paint a metal filing cabinet.

Choose the Right Paint

Choosing the right type of paint is crucial for getting great results when painting metal. Here are some tips:

• Use direct-to-metal paint – This specialized paint adheres best to smooth metal surfaces without requiring a primer first. Look for paint labeled specifically for metal, such as Rust-Oleum.
• Opt for oil-based over latex-based paint – Oil-based enamels harden to a glossy finish and hold up better over time than latex paint on metal surfaces.
• Select rust-preventative paint for rusted cabinets – If the metal has any rust spots, choose a paint designed to halt existing rust and prevent future rust. Rust-Oleum makes a suitable rusty metal primer.
• Consider spray paint for convenience – Spray paint can make painting metal filing cabinets much faster and easier than brush painting. Get an enamel spray paint made for metal.

Prepare the Filing Cabinet

Proper prep work ensures the paint adheres well and provides a long-lasting finish. Here are the key steps:

• Clean the surfaces – Wipe down all surfaces with soap and water, then a degreaser to remove any oils or residues. Rinse and let dry fully.
• Sand if needed – If the metal has a glossy clear-coat or there is any chipping paint, lightly sand to rough up and dull the surfaces, which helps the paint stick better.
• Apply primer – For heavily rusted or damaged cabinets, first apply a rust-inhibiting primer like Rust-Oleum’s Rusty Metal Primer to save the metal.
• Fill any holes/dents – Use auto body filler, putty, or spackling paste to fill in any holes, dents, or grooves for a smooth look after painting. Sand once dry.
• Use painter’s tape – Tape off any hardware, handles, or edges you don’t want painted. Blue painter’s tape allows clean removal.

Paint the Filing Cabinet

When prepped and ready, use these tips for flawless paint application:

• Work in a ventilated area – Paint fumes can be strong, so open windows or doors to allow airflow. Use a respirator mask if needed.
• Apply thin coats – Thin, even coats allow the paint to adhere to the metal better than thick coats. Allow each coat to dry fully before adding another.
• Use smooth strokes – Paint in smooth, overlapping strokes in the same direction. Avoid blotching or whipping the paintbrush.
• Get full coverage – Check sides and edges for any missed spots and “fill in” to ensure complete, uniform coverage.
• Let dry fully – Give the paint several days to cure completely before reattaching any hardware or putting cabinets back into service.

Maintaining the Finish

To keep your painted metal filing cabinets looking fresh, incorporate these maintenance practices:

• Allow paint to cure for 1-2 weeks before cleaning – This allows paint to harden fully before exposing to any chemicals/cleaners.
• Clean gently with mild soap and water – Avoid abrasive cleaners or scouring pads which can mar the painted finish over time.
• Touch up paint chips immediately – Reapply paint right away to any nicks or scrapes to prevent exposed metal from rusting.
• Repaint periodically – Depending on use, reapply a fresh coat every 2-5 years to keep cabinets looking their best.

With high-quality direct-to-metal paint and proper preparation, you can give old metal filing cabinets new life with a durable, protective finish that keeps them looking great for years. The transformed look can re-invigorate your whole office space.

Frequently Asked Questions About Painting Metal Filing Cabinets

Can I use regular latex paint on metal filing cabinets?

No, regular wall paint does not adhere well to smooth metal over time. Opt for an oil-based enamel spray paint specifically made for metal for the most durable finish.

What color should I paint my filing cabinets?

Consider colors that complement your office decor. Neutral tones like gray, beige or black are versatile choices. Bold colors like red or teal add fun vibrancy.

How long does it take for the paint to fully cure?

Oil-based enamel paints take 5-7 days to fully cure and harden on metal surfaces. Avoid heavy use or cleaning during this time.

What Sheen is best – glossy, satin or matte?

For filing cabinets, a gloss or semi-gloss finish is ideal since it is most scratch-resistant and easiest to clean over time. Avoid flat/matte which stains easier.

Can I paint over rust spots without primer?

It’s best to first apply a rust-inhibiting primer like Rust-Oleum to any rusted areas, to protect the metal before painting.

What do I do if paint bubbles or peels off metal?

If bubbling/peeling occurs, the metal surface wasn’t properly sanded and cleaned beforehand. Fully remove paint, clean, sand, and reapply primer and paint.

Can I use chalk paint on metal filing cabinets?

Chalk paint adheres well but provides a matte finish that’s easily marred over time. Opt for enamels in gloss/semi-gloss sheens instead for metal.

Does spray paint or brush paint work better?

Spray paint is faster and provides a smoother finish but requires masking off areas. Brush painting allows more precision but may show slight brush strokes.

How do I paint raised lettering on cabinet fronts?

Use painter’s tape to cover the letters before spraying/brush painting the cabinets. Carefully remove tape right after painting before the paint fully dries.

Conclusion

Giving worn and dated metal filing cabinets new life with a fresh coat of paint is a simple, affordable way to instantly update the look of your office. With the right preparatory steps, using high-quality direct-to-metal paint, allowing proper drying time, and maintaining the finish, you can achieve professional-looking results that keep your filing cabinets looking revitalized for years to come.
