How to Repaint a Metal Filing Cabinet

Repainting a metal filing cabinet can give an old piece of office furniture new life. With some simple preparation, high-quality paint, and attention to detail, you can transform the look of a tired metal cabinet. Here is a step-by-step guide on how to properly repaint a metal filing cabinet.

Introduction

Repainting metal furniture like filing cabinets allows you to inexpensively update the look of your office. With a fresh coat of paint, you can change the color, hide scratches or discoloration, and give the cabinet a more modern appearance. When done properly, a new paint job can make the filing cabinet look brand new.

Before starting the painting process, take time to prepare the filing cabinet to ensure the paint adheres correctly. You’ll also need to choose a high-quality metal paint and prime the cabinet. With attention to detail during the painting process, you can achieve an attractive and durable finish.

Steps to Repaint a Metal Filing Cabinet

Clean and Sand the Cabinet

The first step is to thoroughly clean and scuff the original paint on the filing cabinet. This helps the new paint stick to the surface better.

• Remove the drawers from the cabinet if possible to make the cleaning process easier.
• Wash the surfaces with a degreasing cleaner like TSP substitute to remove any dirt or oils.
• Rinse well and let dry completely.
• Lightly scuff sand all areas to be painted using 180-220 grit sandpaper. This roughs up the surface for better paint adhesion.

Prime the Filing Cabinet

Priming provides an important base layer for the new paint. Be sure to use a high-quality metal primer.

• Apply a thin coat of metal primer to all surfaces using a brush, roller, or sprayer.
• Follow the manufacturer’s recommended drying time before applying a second coat of primer.
• Sand lightly with fine (320 grit) sandpaper between coats to ensure proper adhesion.
• Allow the primer to fully cure per the directions before painting. Proper drying/curing is key.

Paint the Cabinet

You’ll get the best results using specialty metal paint. Apply multiple thin coats for maximum durability.

• For the first coat, thin the paint slightly with the recommended thinner to help it adhere and flow better.
• Apply at least two coats of metal paint, allowing proper drying time between coats.
• Lightly sand between coats to ensure proper adhesion.
• Apply coats in a consistent direction using overlapping strokes.
• Work methodically to avoid drips and sags in the paint.

Finish with Clear Coat (Optional)

For extra protection, apply one or two coats of a clear metal lacquer.

• Optional: Apply thin coats of a clear metal lacquer, allowing proper drying between coats.
• The lacquer helps protect the painted surface from scratches and wear.
• Use spray lacquer for the smoothest possible finish.

Reinstall Drawers

Once the paint has fully cured (refer to manufacturer’s directions), reinstall any drawers. Now you can enjoy your revitalized filing cabinet!

Tips for Success

• Carefully read and follow the paint manufacturer’s instructions for best results.
• Work in a dust-free area to avoid contaminants in the wet paint.
• Apply paint when the temperature is between 50-90°F.
• Sanding between coats promotes maximum adhesion.
• Apply thin coats rather than one thick coat for a smooth finish.
• Use high-quality primer and paint designed specifically for metal.
• Allow proper drying and curing times between coats.
• Work slowly and methodically for an even finish without drips.
• A sprayed lacquer top coat gives the most durable, scratch-resistant finish.
