Introduction
Painting metal furniture like file cabinets is a relatively easy DIY project that can make a big difference in the overall look of your space. With some sanding, priming, and a few coats of paint, you can give new life to an old metal file cabinet. The key steps are preparation, choosing the right paint, and applying it correctly. Follow this guide to learn how to paint a metal file cabinet and get professional-looking results.
Steps to Paint a Metal File Cabinet
Clean the Surface
Before painting, it’s essential to thoroughly clean the file cabinet to remove any dirt, grease, or residue. Use a degreaser or all-purpose cleaner and scrub with a sponge or rag. Rinse and let dry fully. Remove any flaking paint with sandpaper or a metal brush. The cleaner the surface, the better the paint will adhere.
Sand the Cabinet
Use 120-150 grit sandpaper to scuff up the entire surface. This helps the primer and paint stick better. Sand lightly but thoroughly, focusing on any problem areas with peeling or chipped paint. Vacuum away all dust after sanding.
Apply Primer
Choose a high-quality metal primer made specifically for metal surfaces. Apply a thin coat of primer using a foam roller or brush. Let the primer dry fully before moving onto painting. The primer coat provides an essential base layer for the paint.
Choose the Right Paint
For metal file cabinets, the best paints are acrylic or oil-based enamel paints, or spray paints made specifically for metal. Latex paint usually won’t adhere well. Opt for a satin or semi-gloss finish for easy cleaning. Make sure the paint is suitable for indoor use.
Apply Paint
Use a foam roller and angled brush to apply the paint smoothly and evenly. Work in sections and maintain a wet edge to prevent lap marks. Apply 2-3 thin coats of paint for complete coverage, letting each coat dry fully before adding another. Allow the final coat to cure for at least 24 hours before use.
Add Protective Clear Coat (Optional)
For extra protection on frequently used file cabinets, apply 1-2 coats of clear polyurethane after the paint has cured. This adds a protective barrier and makes the finish more scratch-resistant.
Tips for Painting Metal File Cabinets
- Use painter’s tape to mask off hardware, edges, and adjacent surfaces.
- Paint the cabinet doors separately for easier access.
- Paint the inside of the cabinet first, then the outside.
- Use a small foam roller and angled brush for best results.
- Work in a well-ventilated area and allow proper drying time between coats.
- Coat cabinet edges and hardware using a small brush.
- Lightly sand between coats for maximum adhesion.
- Apply paint thinly and evenly to avoid drips and sags.
What Kind of Paint to Use
When choosing paint for a metal file cabinet, here are the best options:
- Oil-based enamel paint – Hardwearing and protective finish. May require mineral spirits for cleanup.
- Acrylic enamel paint – Durable, fast-drying, and easy cleanup with water. Ideal for indoor use.
- Rust-oleum spray paint – Available in many colors and finishes. Works well for metal.
- Automotive paint – Formulated for metal and provides a tough, glossy finish.
- Chalk paint – Popular for furniture refinishing but may require a protective topcoat.
Avoid standard interior latex paints as they don’t adhere well to slick metal surfaces like file cabinets. Stick with paints formulated specifically for metal for the most durable finish.

- Use painter’s tape to mask off adjacent walls or cabinets.
