How to Remove Paint from Metal File Cabinet

Removing paint from a metal file cabinet can seem like a daunting task, but with the right techniques and tools, it can be done effectively. Painting metal filing cabinets is a popular way to update their look. But over time, the paint may become chipped, faded or just look dated. Refinishing and removing the old paint to get down to the original metal surface takes some work, but can give your old filing cabinets a brand new look.

Why Remove Paint from a Metal File Cabinet?

There are several good reasons you may want to remove paint from a metal filing cabinet:

• Update the look – Sometimes painted metal cabinets can start to look worn, chipped or dated over time. Removing the paint allows you to take them back to the original metal finish or repaint them a fresh new color. This can give old cabinets a modern, updated look.
• Fix paint problems – Paint on metal surfaces can start bubbling, cracking, peeling or chipping over time as the paint ages. Removing the paint allows you to take it back to the bare metal and provides a smooth, even surface for repainting if desired.
• Remove outdated colors – Tastes change over time. That bright blue filing cabinet looked great in the 90s but may seem dated now. Removing old paint allows you to update the color to something more current.
• Match other decor – If you have newer stainless steel or metal finish furniture or decor in the same space, removing paint from the filing cabinets allows you to match the finishes and create a more cohesive look.
• Improve value – Refinished metal pieces often increase in value over painted pieces. Removing old paint can help improve the value of vintage or antique cabinets.

No matter what the reason, removing paint from metal filing cabinets properly takes some work. The following steps will help you through the process.

How to Remove Paint from a Metal File Cabinet

Removing paint from a metal cabinet is a multi-step process. With the right approach and supplies, you can take paint off safely and effectively to reveal the original metal surface. Here are the key steps:

1. Empty the Filing Cabinet

Before starting to work on removing paint from the filing cabinet, fully empty it out. Remove all files, folders, drawers, and any other contents until the cabinet is completely empty. This gives you full access to all surfaces and makes the cabinet lighter and easier to move. Set the drawers, shelves and all contents aside in a safe place until the paint removal process is complete.

2. Disassemble Components

Use a Phillips head screwdriver to remove any handles, hinges or other hardware attached to the filing cabinet. Set all of the hardware pieces aside together, so they can be easily reattached later. Removing the various cabinet components provides better access for stripping paint. It also prevents damage to the hardware during the process.

3. Clean the Surfaces

Give the filing cabinet a thorough cleaning to remove dirt, oil, grease and grime. Degreasing agents or solutions work well for this cleaning step. Tackle both the interior and exterior surfaces. A degreased, cleaned surface allows the paint removers and strippers to work more effectively.

4. Sand Rough or Peeling Edges

Examine the surfaces of the metal filing cabinet for any areas where paint may already be cracked, peeling or bubbling. Use 120-150 grit sandpaper to gently smooth and feather out these rough edges. Sanding prepares these damaged areas and helps prevent the paint remover from pulling off large chips.

5. Apply Paint Remover

Start applying a paint removing solution or stripper to the metal filing cabinet. Use a product specifically designed for removing paint from metal surfaces. Apply a thick layer of the remover evenly across all surfaces using a paintbrush. Be sure to follow the manufacturer’s instructions closely. Let the remover sit for the recommended amount of time to allow it to fully penetrate and dissolve the layers of paint.

6. Scrape Away Paint

After allowing proper time for the remover to work, use a plastic or metal paint scraper to start scraping away the dissolved paint. Apply firm but even pressure and scrape at a low angle to pull up the loosened paint strips. Keep scraping until you reveal as much of the original metal beneath as possible. Use a plastic bristle scrub brush and rags dampened with remover to get into small crevices and details.

7. Rinse With Water

Once most of the paint is scraped up, rinse the filing cabinet with clean water. This helps to neutralize and remove any remaining remover solution or paint residue. Rinsing also allows you to see if more scraping or sanding is needed to get back to the bare metal. Be sure to thoroughly dry all surfaces after rinsing.

8. Sand and Scrub

Examine the surfaces after rinsing. Use 150-220 grit sandpaper to sand and scrub any remaining paint spots. This smooths and evens the metal surface. Focus on sanding just until all remnants of old paint are removed and the natural metal is revealed. Be careful not to overly scratch or gouge the metal.

9. Clean and Prepare for New Finish

Give the filing cabinet one final wash with a degreasing cleaner and water. This is especially important if repainting or adding a new finish. Proper preparation helps paint or finishes adhere evenly. Allow the metal surfaces to fully dry after the final rinse and cleaning. Once dry, you can apply primer, fresh paint or add a clear finish.

10. Reassemble Cabinet

After removing the paint and allowing proper drying time, reattach the handles, drawers, shelves and hardware. Check alignments and make any minor adjustments needed so drawers operate smoothly. Once reassembled, load items back into the newly refreshed filing cabinet. Admire the updated “new” look!

Tips for Removing Paint from Metal Filing Cabinets

Common Problems When Removing Paint from Metal File Cabinets

The paint removal process on metal filing cabinets doesn’t always go smoothly. Here are some common problems that may arise, along with troubleshooting tips:

Paint stripper drying too fast – This is often caused by applying remover too thinly or working in very hot, sunny conditions. Work in shade and apply a thicker amount of remover to prevent this.

Excess scratching or gouging of metal – Using sharp metal scrapers or excessive pressure causes scratches. Use plastic scrapers and moderate, even pressure to avoid damage.

Remover not penetrating well – Old, thick paint may require repeat applications and scrubbing to fully penetrate the layers. Allow proper dwell time and reapply remover to trouble spots.

Residue left on surface – Not rinsing well after stripping leaves residue that impacts adhesion of new paint. Rinse repeatedly to remove all stripper and paint residue.

New paint not adhering – Grease, oil or soap left on the surface can cause poor paint adhesion. Proper degreasing and prep of the bare metal is critical before painting.

Removing hardware screws – Bolts can fuse with paint over time. Applying penetrating oil a day or two before disassembly can help loosen fused components. Slowly ease apart.

Drawers or doors sticking – Paint buildup or uneven stripping under edges can cause sticking. Fully strip all sides and sand or plane sticking edges for smooth operation.

With some troubleshooting and adjusting your technique, these common issues can be overcome for the best results.

What Kind of Paint to Use When Refinishing a Metal File Cabinet

Once you’ve taken a metal filing cabinet down to the original bare metal, properly preparing the surface and selecting the right type of paint is key for a long-lasting finish. Here are some tips on choosing new paint:

• Use a metal primer – It’s critical to first apply a coat of metal primer formulated for metal surfaces before painting. This allows for maximum adhesion.
• Select an enamel paint – Oil or latex enamels are ideal for metal. The hard, glossy finish resists wear, scrapes and chips from daily use.
• Consider high-quality spray paint – Spray enamels adhere evenly and create a smooth finish. Just be sure to apply light coats.
• For durability, use industrial paint – Commercial-grade epoxy or powder coating paints provide extreme durability for high-use filing cabinets.
• Get matching touch-up paint – Touch-up pens in matching paint colors allow for quick fix scratches or chips down the road to keep your finish looking fresh.

Choosing the right type of paint and properly prepping the surface ensures your newly stripped filing cabinet maintains a beautiful finish for years before needing to remove paint again!

How Much Time Does It Take to Remove Paint from a Metal File Cabinet?

The amount of time needed to strip paint from a metal filing cabinet depends on several factors:

• Age and Type of Paint – Newer latex paints strip faster than old oil-based enamels or thickly applied layers. Multiple paint layers take longer.
• Paint Condition – Intact paint takes longer to strip than cracked or peeling paint. Removing small spots in good condition goes quicker.
• Cabinet Size – Large double or triple width file cabinets require more time than a single small drawer unit. More surface area adds time.
• Stripping Method – Chemical strippers work faster than sanding alone. Power sanders and grinders also speed the stripping process.
• Trouble Spots – Intricate details and crevices often need repeat applications and scrubbing, adding to project duration.

For a standard two or three drawer file cabinet in moderate condition, allocating 2-4 hours for the stripping process is reasonable. Bigger jobs with thick, peeling paint could take 6-8 hours or more of active work time. Building in some extra time ensures no need to rush the project.

FAQs About Removing Paint from Metal File Cabinets

Removing years of built-up paint from metal filing cabinets comes with many questions. Here are answers to some of the most frequently asked questions:
