How to Refinish a Metal Filing Cabinet

Follow these key steps for refinishing a metal filing cabinet:

Supplies Needed

To properly refinish a metal filing cabinet you will need:

• Paint stripper – to remove old paint/finish
• Sandpaper – ranges from coarse (80-100 grit) to fine (120-220 grit)
• Tack cloth – to wipe away dust between sanding
• Primer – specifically formulated for metal
• Paint – spray cans work best for full coverage
• Rags, gloves & eye protection – for safety

Optional supplies:

• Orbital sander – for faster, easier sanding
• Paintbrush – for trim or corners
• Foam roller – to roll large flat surfaces

Step 1 – Empty the Filing Cabinet

Before starting the refinishing process, fully empty the filing cabinet of all files, folders and contents. Depending on the refinishing methods you’ll be using, it’s best to do this project with the cabinet empty to allow full access to all surfaces.

Step 2 – Remove Drawers

The drawers will need to be refinished separately from the main cabinet. Remove all the drawers from their slides and set aside carefully. Label them if needed so you can easily reinstall in the proper configuration.

Step 3 – Clean the Surfaces

Give the emptied cabinet a thorough cleaning inside and out before refinishing. Use a degreasing cleaner and rinse well to remove dirt, oils, dust and debris. Let fully dry. This allows the new paint to properly adhere.

Step 4 – Scuff Up Glossy Areas

If there are any glossy surfaces or smooth finishes, scuff them up lightly with sandpaper. This helps the primer and new paint bond properly.

Step 5 – Apply Paint Stripper

Read and follow the product directions for applying your paint stripper safely. Brush a thick coating of stripper over all surfaces and let it sit for the recommended time before scraping away the old chipping or peeling paint. The stripper will soften several layers so you can remove them at once. Wear gloves and work in a well-ventilated area.

Step 6 – Wash Off Stripped Surfaces

Once you’ve scraped off all the loosened paint, use a rag dipped in stripper to wipe any residual coating away. Follow up by washing all the stripped surfaces with soap and water to remove any remaining stripper or paint residue.

Step 7 – Sand All Surfaces

Once stripped down to the bare metal, start sanding to smooth and prep the surfaces. Work your way through the grits starting with a coarse 80-100 grit sandpaper to remove any remaining paint or rust, then gradually sand with finer 120-220 grit sandpaper as you get down to smooth metal.

Step 8 – Wipe Away Dust

Be sure to carefully wipe away all dust between sanding with a tack cloth. This prevents dust nibs in your final paint job.

Step 9 – Spot Prime as Needed

If there are any areas of exposed bare metal or rust spots, spot prime just those areas with a quality metal primer. This protects the vulnerable metal before painting.

Step 10 – Apply Primer Coats

Once fully sanded and cleaned, apply 1-2 layers of primer formulated specifically for metal. Used automotive primer works well. Lightly sand with fine sandpaper between coats. Primer creates a base layer that allows the paint to adhere.

Step 11 – Add Paint Finish

Now you’re ready for the fun part – choosing a finish! Paint the filing cabinet and drawers with spray cans for the most uniform coverage. Follow the can directions for best results and allowing proper dry time between coats. Consider a high gloss paint for a smooth, professional look.

Step 12 – Reinstall Drawers

After allowing the paint to fully cure per can directions, carefully reinstall the painted drawers onto their slide rails in the proper configuration. Test to make sure they open and close smoothly. Add a drop of lubricant to the slides if needed.

Step 13 – Add Updated Hardware

Freshen up your filing cabinet even more with updated hardware like new knobs, handles or locks. This finishes the new refinished look.

With patience and proper prep work, you can completely transform the look of a worn-down metal filing cabinet. The end result will look professionally refinished at only a fraction of the cost. Enjoy your revitalized filing cabinet!

Supplies and Tools to Prepare

To ensure your filing cabinet refinishing project goes smoothly, it is important to gather the proper supplies and tools ahead of time. Here is an overview of what you will need:

Paint Stripper

A high-quality paint stripper is needed to penetrate and remove the existing finish and/or paint on your filing cabinet. Choose a stripper formulated for metal that can quickly and effectively remove old paint without damaging the underlying surface.

Sandpaper

Sandpaper in a range of grits will be needed to scuff, smooth and prep the surfaces for new paint. Have on hand:

• Coarse sandpaper (80-100 grit) to rapidly remove paint/rust
• Medium sandpaper (120-150 grit) for general smoothing
• Fine sandpaper (180-220 grit) for finishing preparation

Tack Cloth

A tack cloth is a must for wiping away all the dust between sanding to prevent paint flaws. The slightly sticky fabric picks up every speck of dust.

Primer

It’s critical to prime the bare metal filing cabinet before painting to ensure proper adhesion. Use a primer specifically made for metal. The rust-inhibitive formulas also protect the metal.

Paint

Choose a high quality spray paint in your desired finish and color specially formulated for metal and furniture use. Enamel, acrylic or lacquer paints all work well.

Rags

Have rags or paper towels on hand for applying stripper, wiping surfaces, cleaning up drips or spills, and more. Shop rags or soft cotton rags are ideal.

Gloves

Wear protective gloves when using paint stripper or primer. Latex, nitrile or rubber gloves are good options. Safety first!

Eye Protection

Safety glasses or goggles should be worn when stripping or sanding to prevent harm to your eyes from chemicals, dust and debris.

Paintbrushes

Keep some extra paintbrushes in various sizes to handle trim, corners and details that spray paint may miss. Disposable foam brushes also work.

With the right supplies gathered ahead of time, your filing cabinet refinishing will go much faster and the end results will look fantastic.

Step 2: Clean Surfaces

Give the filing cabinet a thorough cleaning with a degreasing cleaner to remove built-up grime and oils. Rinse well and let dry fully.

Step 3: Scuff Glossy Areas

Use 150 grit sandpaper to scuff up any glossy or slick surfaces to help the primer adhere properly. Wipe away sanding dust.

Step 4: Apply Paint Stripper

Cover all surfaces with a thick even coating of paint stripper. Allow to sit for 5-10 minutes before scraping away paint with a putty knife.

Step 5: Wash Off Stripped Surfaces

Wipe all surfaces with stripper soaked rags to remove residual paint and stripper. Follow up by washing all areas with soap and water.

Step 6: Sand All Surfaces

Start with 80-100 grit sandpaper to remove remaining paint and rust. Smooth with 120-150 grit. Finish sanding with 180-220 grit to prep for primer.

Step 7: Wipe Away Dust

Use a tack cloth to meticulously wipe away all dust between sanding to prevent paint flaws.

Step 8: Spot Prime Bare Metal

Cover any exposed bare metal or rust spots with a thin coat of metal primer. Let dry fully.

Once paint has fully cured, put drawers back in their original configuration. Test to make sure they open and close smoothly.

Step 12 (Optional): Add New Hardware

Freshen up with new knobs, handles, locks or other hardware for the perfect finishing touch.

Tips for a Smooth, Flawless Finish

Follow these tips and tricks to get the very best results from your filing cabinet refinishing project:

Work in a Well-Ventilated Area

Paint fumes and chemical strippers can quickly build up in enclosed spaces. Always refinish in a garage, outdoors or near open windows. Consider wearing a respirator.

Follow Product Instructions

Closely follow the directions on any paint stripper, primer, paint or other product used. This ensures ideal results and safety.

Apply Thin, Even Coats

When painting, spray light, thin coats rather than trying to fully cover in one thick coat. Several thin coats create a smoother finish.

Allow Proper Dry Times

Rushing the drying steps can ruin the paint job. Follow the label recommended dry times between all coats of primer, paint, etc.

Sand Lightly Between Coats

Gently sanding with fine 220 grit sandpaper between coats promotes better adhesion from coat to coat.

Wipe Away Dust Frequently

Wipe all surfaces thoroughly with a tack cloth before priming and painting. Trapped dust leads to an uneven finish.

Maintain Consistent Spray Distance

Hold spray cans 6 to 8 inches away and at consistent distance to prevent drips or thin spots in paint coverage.

Use Smooth Motions

Paint in straight overlapping paths, using smooth back and forth motions with spray cans for an even coat.

Paint Inside Drawers and Cabinets

Don’t forget to refinish the interior drawers and cabinet insides to get the full facelift.

With proper preparation and care taken during application, you can achieve a gorgeous, professional-looking refinished filing cabinet. The extra effort is well worth it!

Common Questions

What kind of paint should be used to refinish a metal filing cabinet?

It is best to use specialty spray paints designed for metal and furniture, such as enamel, acrylic or lacquer paints. Avoid standard paints which may not adhere well. Look for finishes rated for metal use.

What causes brush marks or an uneven finish when painting?

Applying paint too thick, not properly priming, spraying from inconsistent distance or angling, or rushing the drying time can all lead to a uneven, flawed finish. Working in very humid or cold conditions can also affect results.

What grit sandpaper is best for preparing a filing cabinet to be painted?

Start with a coarse 80-100 grit sandpaper to strip away existing paint and smooth surfaces. Then use 120-220 grits to finely prep for primer and paint. Be sure to wipe away all dust between sanding.

Should you clean the metal filing cabinet with soap and water before starting?

Yes, it’s important to thoroughly clean all surfaces with a degreaser or soap and water. This allows for optimal adhesion of the primer and paint. Remove any oils, dirt or residue.

How can you avoid chips and scratches when refinishing a filing cabinet?

Use high quality primers and paints designed for metal furniture. Allow proper drying times between coats. Carefully reinstall drawers and avoid slamming them. Add felt pads to bottom drawer corners.

Can you change the color of a filing cabinet without completely stripping it?

For the best, longest lasting results it is best to take it down to the bare metal before priming and painting a new color. Trying to paint over an existing finish often leads to chipping or peeling down the road.

What kind of primer should be used when refinishing a metal filing cabinet?

It’s crucial to use primer specifically formulated for metal when refinishing filing cabinets. The anti-rust properties help protect the metal underneath while improving paint adhesion.

Is there a big difference between refinishing metal versus wood filing cabinets?

Metal and wood refinishing follow the same basic process of stripping, sanding, priming and painting. But metal-specific primer and paint must be used. Different stripping products are also needed for each material.

Can spray paint be used to refinish an old metal filing cabinet?

Yes, spray paint is highly recommended for refinishing filing cabinets. The aerosol spray allows you to apply thin, even coats across all surfaces – tops, sides, fronts, backs, trim and inside drawers. Roller paint or brush paint are difficult to apply evenly.

Refinishing a worn out filing cabinet may seem intimidating but with the right preparation and materials it can be a fun, rewarding DIY project. Follow these tips and techniques and you’ll have a beautifully updated cabinet with a durable, professional finish.

Best Paint Color Options to Consider

Choosing a fresh new paint color is one of the most exciting parts of refinishing a metal filing cabinet. You can select virtually any color to match your office or home. Here are some of the best color options to consider:

Neutral Tones

Timeless neutral shades like creamy white, dove gray, tan or soft beige are smart choices. They complement any décor and won’t go out of style.

Bold or Vibrant Colors

Make a statement with vibrant reds, oranges, yellows, greens or blues if you want an eye-catching accent piece. Just be sure it fits your overall room scheme.

Metallic Finishes

On-trend metallic paints like silver, gold, bronze or copper create a modern, sleek, stylish look. Just avoid very dark metallic colors which show scuffs.

Black or Charcoal

For a luxe, sophisticated look consider satin or matte black or charcoal. Keep drawers lubricated so black doesn’t scuff up.

Wood Tones

Faux wood grain finishes like mahogany, oak, walnut and cherry simulate real wood at a fraction of the cost. Great for traditional style rooms.

Chalkboard Paint

For a fun, funky vibe use chalkboard paint to cover the cabinet fronts. Kids will love it! Use chalk to label drawers or get creative.

Match Wall Color

Choose your exact wall color for cohesive, seamless look. For example, paint the cabinet robin’s egg blue to match a blue home office.

Vintage Appeal

Soft pastel greens, blues, pinks or yellows give a cute cottage or vintage vibe. Distress edges slightly for an antique look.

The options are endless when picking a filing cabinet paint color. Choose a shade that fits your personality and décor style. Don’t be afraid to get creative with unique finishes!

How to Add Decorative Hardware

Once your filing cabinet facelift is complete, think about adding some decorative hardware to really make it pop. Swapping out standard metal handles or knobs for more stylish options can take the look up another notch. Here are some ideas:

Vintage Glass Knobs

Glass knobs in etched, pressed or crystal styles have a timeless vintage appeal. Look for colors like amber, smoky gray or clear. Add to drawers or doors.

Ceramic Pulls

Ceramic is on trend, with artisan glazed knobs available in unlimited colors and shapes like rectangles, circles or squared. Fun for a retro modern look.

Crystal Pulls

For some glam, crystal and jewel toned hardware catches the light beautifully. Opt for simple rectangular pulls or ornate crystal knobs.

Wooden Knobs
