How to Paint a Metal Filing Cabinet with Rust-Oleum Chalk Paint

Painting a metal filing cabinet with chalk paint is an easy way to give it a quick makeover. Chalk paint adheres well to metal and dries into a matte finish that keeps the charm of the metal showing through. Rust-Oleum is a popular brand of chalk paint that comes in a wide range of colors. With just a few simple steps, you can transform a plain metal cabinet into something stylish.

What You’ll Need

• Rust-Oleum chalk paint in the color(s) of your choice
• Paintbrush and/or small foam roller
• 220 grit sandpaper
• Tack cloth
• Drop cloth or painters tape
• Polyurethane (optional)

Prep the Cabinet

Before painting, you’ll need to prep the filing cabinet to help the paint adhere properly.

• Remove the drawers from the cabinet. Having the drawers out will make painting the cabinet much easier.
• Lightly sand the cabinet with 220 grit sandpaper to rough up the surface. This helps the paint grip.
• Wipe off any dust with a tack cloth. Make sure the surface is clean and grease-free.
• Lay a drop cloth on the floor or use painters tape to cover any areas you don’t want to get paint on.

Paint the Cabinet

Once prepped, you’re ready to paint.

1. Apply the First Coat

• Stir or shake the chalk paint before opening. Chalk paint separates in the can and needs to be mixed.
• Use a brush for the edges and corners. Then switch to a small foam roller for the flat surfaces. This saves time and minimizes brush strokes.
• Paint in thin, even coats. Avoid getting too thick or the paint may not cure properly.
• Work systematically from top to bottom. Paint the outside of the cabinet first, then the inside, and finally the drawers.

2. Let Dry Completely

• Allow the first coat to dry for at least 1-2 hours before proceeding.
• Drying time may vary based on temperature, humidity, and thickness of the paint. Test a small area before applying a second coat.

3. Apply Second Coat and Let Dry

• For full coverage, a second coat is usually needed. Again, use thin even coats.
• Allow the final coat to dry 24 hours before reattaching the drawers and using the cabinet.

Finish with Polyurethane (Optional)

For added protection on a filing cabinet that will get a lot of use, apply a coat of water-based polyurethane.

• Allow the paint to dry at least 24 hours before applying polyurethane. Lightly sand any rough spots first.
• Apply polyurethane with a foam brush. Use thin, even coats and allow 2-3 hours drying time between coats.
• Two or three coats of polyurethane is usually sufficient.
• Allow the final coat to dry 24 hours before use.

And that’s it! With just a little time and effort, you can give a plain metal filing cabinet new life with Rust-Oleum chalk paint. The matte finish will add stylish texture and color.

Tips for Painting a Metal Filing Cabinet

Follow these tips to ensure your painted filing cabinet turns out beautifully:

• For a smooth finish, use high-density foam rollers and quality bristle brushes.
• Tape off any areas you don’t want painted like the cabinet interior or hardware.
• To avoid drips, always paint vertically and work top to bottom.
• Apply thin coats and allow proper drying time between coats.
• For dark colors, use a primer first for better coverage.
• Clean the brushes promptly after using with warm soapy water.
• If covering over an existing painted surface, scuff sand it before painting to help adhesion.
• Work in a dust-free area to minimize contaminants in the paint.
• Paint the cabinet drawers separately for easier handling.
• Seal paint with polyurethane for enhanced durability and stain resistance.

Common Questions

Can I use chalk paint on metal?

Yes, chalk paint adheres very well to metal surfaces. It dries to a matte finish that shows off the metal texture beautifully.
