Painting a metal filing cabinet can help give it a fresh, updated look. While using a paintbrush is an option, a roller may be a faster and easier way to get full coverage. Here is what you need to know about using a roller to paint a metal filing cabinet.

Clean and Prepare the Surface

Before painting, it is essential to properly clean and prepare the filing cabinet’s surface. This will help the new paint adhere and give you the best possible finished look.

• Remove the drawers from the cabinet so you can easily access all sides.
• Clean the surfaces with a grease-cutting degreaser to remove any built-up grime or oils. Wipe down with a tack cloth.
• Lightly scuff the surfaces with fine sandpaper to rough them up and help the paint adhere.
• Clean the surfaces again with a tack cloth to remove any dust.
• Apply a high-quality primer made for metal. Allow to fully dry per the manufacturer’s instructions.

Proper prep is the key to getting great results when painting a metal filing cabinet. Taking the time to clean and slightly scuff the surfaces will allow for maximum paint adhesion.

Choose the Right Paint

For painting metal filing cabinets, latex or oil-based primers and paints are recommended. The paint should state on the label that it is intended for use on metal or steel.

• Latex paint dries more quickly and has less odor than oil-based options. It still provides good adhesion on properly prepped metal surfaces.
• Oil-based paint takes longer to dry but provides a very hard, protective finish. It adheres exceptionally well to metals.

Opt for interior paints rather than exterior options since the filing cabinet is for indoor use. Semi-gloss or high-gloss sheens make for very durable and scrubbable finishes.

Use a Paint Roller for Quick Coverage

A 3/8″ nap roller cover works well for smoothly painting metal filing cabinet surfaces. The short nap provides just enough texture to apply the paint without leaving behind any lint or fuzz.

Here are some tips for quick and even coverage using a roller:

• Pour paint into a tray and load the roller by rolling it back and forth in the tray. Spin the roller against the ridged part of the tray to evenly distribute the paint.
• Start by painting the top flat surfaces of the cabinet, applying long overlapping strokes with the roller. Move methodically side-to-side.
• Next, roll the paint onto the vertical sides using up and down strokes. Apply even pressure to avoid drips.
• For small or hard-to-reach areas, use a brush to smoothly blend the paint rather than trying to force the roller into tight spaces.
• Work in sections and maintain a wet edge as you paint. This helps avoid lap marks as you move from section to section.
• Allow each coat to fully dry before adding another. Lightly sand any drips or rough spots between coats.
• Add two or three coats for a rich, evenly coated finish.

Using a mini paint roller makes quick work of covering all the surfaces of a standard four-drawer filing cabinet. Take care on edges and corners to avoid excess paint buildup.

FAQs About Painting a Metal Filing Cabinet

Can you use a paint sprayer instead of a roller?

Yes, a paint sprayer is another option for coating a metal filing cabinet. It can provide smooth, even coverage much like a roller. Be sure to prep the surface and apply primer first. Carefully mask off any areas you don’t want sprayed.

What kind of paint primer should be used?

For best adhesion, use a primer specifically made for metal such as Rust-Oleum Clean Metal Primer or Krylon Dual Superbond Primer. Some all-in-one paint+primer products also work well directly on metals.

How long does it take for the paint to cure?

Most paints take 1-2 weeks to fully cure and harden. Avoid putting anything abrasive in the drawers during this time. The paint may dent or scratch easily while curing if items rub against it.

Can you paint over rust spots?

For small rust spots, sand the area smooth then apply primer before painting. For heavier rust, use a rust converter product first to transform the rust into an inert layer that can be painted over.

Should drawer pulls be removed before painting?

Yes, remove any hardware like handles or pulls prior to painting. This allows for easier painting and avoids getting paint on the hardware pieces. Reattach after the paint has dried.

Painting a Metal Cabinet Provides an Update on a Budget

Painting metal filing cabinets using a roller and latex paint is an easy, beginner-friendly project that makes a huge visual impact. With proper prep work and a few coats of durable interior paint, you can give beat-up old cabinets new life. The smooth, glossy finish that a roller provides makes the cabinet look store-bought rather than DIY. With a little time and effort, you can affordably update the look of your home office or any space needing organized storage.

Conclusion

Painting metal filing cabinets with a roller can provide a smooth, professional-looking finish. The key steps are properly preparing the surface, choosing appropriate paint, and using proper rolling techniques for even coverage. A short-nap roller makes quick work of covering large flat surfaces. With multiple coats of interior paint and some simple prep, metal filing cabinets can be given an updated, durable, and customizable finish that suits any decor.
