How to Paint a Metal File Cabinet with Chalk Paint

Painting old metal file cabinets with chalk paint is an easy way to give them a fresh, updated look. Chalk paint adheres well to metal and creates a smooth, matte finish that lets the character of the metal shine through. With just a few simple steps, you can transform an outdated metal cabinet into a stylish storage piece.

Benefits of Using Chalk Paint on Metal

Chalk paint has several advantages when painting metal:

• Adheres to smooth surfaces like metal: The chalky consistency allows chalk paint to grip onto slippery surfaces like metal filing cabinets without the need for sanding or priming. This saves time prep work.
• Self-leveling formula: Chalk paint levels out brush strokes for a smooth, consistent finish. This helps hide imperfections in old metal cabinets.
• Matte finish: The flat, matte look lets the natural texture of the metal show through. This gives a rustic, vintage look.
• Doesn’t require sealing: Chalk paint cures naturally into a hard, durable finish without a top coat of polyurethane or wax.
• Easy Soap and Water Cleanup: Chalk paint brushes and rollers can be cleaned up with just soap and water since it’s water-soluble. No need for mineral spirits or harsh solvents.

Supplies Needed

Before starting your chalk paint project on a metal filing cabinet, gather these supplies:

• Chalk paint in your desired color(s)
• Paintbrushes (flat and angled sash work well)
• Paint roller and tray
• 220 grit sandpaper
• Tack cloth
• Drop cloth
• Painters tape
• Soft rags
• Water and mild soap (for cleanup)

Prep the Metal Cabinet

Proper prep ensures the chalk paint adheres well to the metal:

1. Clean the surface: Wipe down the cabinet with a damp cloth to remove any dust or oils. Let dry completely.
2. Sand lightly: Lightly sand the metal with 220 grit sandpaper to rough up the smooth surface. This helps the paint grip.
3. Wipe clean: Use a tack cloth to remove any dust after sanding.
4. Tape off edges: Use painters tape to tape off any adjacent surfaces you don’t want to get painted.
5. Apply drop cloth: Place a drop cloth on the floor under the workspace. Chalk paint can get messy.

How to Apply Chalk Paint to Metal

Follow these steps for a smooth chalk painted finish:

1. Stir Paint Well

Stir the chalk paint thoroughly before starting. This reconstitutes any pigment that settled.

2. Apply First Coat

Use a combination of a brush and small foam roller to apply the first coat. Work in sections starting with the interior of the cabinet. Paint with the grain of the metal.

3. Let Dry

Allow the first coat to dry completely for at least 1 hour. Cooler temperatures may require longer drying times.

4. Lightly Sand

Gently sand the first coat with 220 grit sandpaper. This helps smooth out the finish.

5. Wipe Away Dust

Wipe away any dust with a dry tack cloth after sanding.

6. Apply Second Coat

Apply a second coat of chalk paint using a foam roller and brush. Allow to dry completely before moving on.

7. Repeat Sanding/Top Coat Steps

For a really smooth finish, do another light sanding with 320 grit sandpaper and follow with a third thin coat of paint.

8. Remove Tape

Once fully dry, remove any painters tape used to mask off sections.

9. Clean Up

Wash brushes with mild soap and water. Use a damp cloth to wipe up any drips or spills before they dry.

And that’s it! With just two to three thin coats of chalk paint and a light sanding in between, you can give metal filing cabinets a smooth, updated look. The chalk paint will cure into a hard, durable finish over the first two weeks. Avoid any heavy cleaning during this period. Then enjoy your refreshed vintage storage piece.

Tips for Achieving the Best Results

Follow these tips and tricks for getting flawless results when painting metal with chalk paint:

• Always work in thin, even coats of paint. Thick coats can cause brush strokes.
• Maintain a wet edge as you paint. This prevents lap marks in the finish.
• Use high-quality applicator tools. Cheap brushes can leave frustrating brush marks.
• Work in a dust-free space. Dust particles can stick to the tacky paint.
• Don’t over-sand between coats. Scuff sanding primes the surface. Over-sanding can expose bare metal.
• Chalk paint dries fast. Don’t rework areas once drying begins or you may pull up paint.
• Seal paint with wax on pieces that will get heavy wear. This adds an extra layer of protection.

Alternative Ways to Use Chalk Paint on Metal

Beyond filing cabinets, chalk paint also looks fantastic when used on:

• Metal office furniture: Give old metal desks, tables, and shelving a makeover.
• Dressers and cabinets: Use on vintage metal kitchen cabinets or dresser drawers.
• Outdoor metal furniture: Refresh wrought iron patio sets and aluminum chairs.
• Appliances: Paint a vintage refrigerator or give your metal kitchen cart an update.
• Accessories: Use on lamp bases, chandeliers, and decorative tin pieces.

So try chalk paint beyond just filing cabinets! It adheres great to all types of metal furnishings and accessories.

Frequently Asked Questions

Does chalk paint need a primer on metal?

The thick consistency of chalk paint allows it to adhere well directly to metal without a separate primer coat. Always scuff sand first before painting for the best grip.

What sheen does chalk paint have on metal?

Chalk paint dries to a flat, matte finish on metal filing cabinets. This allows the natural patina and texture of the metal to show through.

Can you use chalk paint on rusty metal?

Lightly sand and wipe down any rusty areas first. Chalk paint can then adhere to lightly rusted metal but may not work as well on heavily rusted surfaces.

How do you seal chalk paint on metal?

Chalk paint doesn’t require a top coat on metal. However, if you want added protection from wear, apply a coat of clear wax or polyurethane.

How long does it take for chalk paint to cure on metal?

Chalk paint takes about 30 days to fully cure and harden on metal filing cabinets. The paint will be dry to the touch in 1-2 days but continues hardening over the first month.
