Can You Put Latex Paint on a Metal Filing Cabinet?

Painting a metal filing cabinet can help update its look or match a new decor. While oil-based enamels have traditionally been used for painting metal, latex paints have improved greatly and can also work well. There are some important considerations when choosing latex paint and preparing the filing cabinet for the best results.

Should You Use Latex Paint on a Metal Filing Cabinet?

Latex paint, also called acrylic paint, has some advantages over oil-based enamel for DIYers:

• Latex paints are water-based, making cleanup much easier with just soap and water. Oil-based enamels require mineral spirits for cleaning up.
• Latex paints emit less odor and volatile organic compounds (VOCs).
• Latex paint dries more quickly than enamels.
• Latex is available in more sheens from flat to high-gloss.

However, latex paint also has some disadvantages vs. enamels:

• It can scratch or chip more easily. Enamel is tougher and more durable.
• Latex may require more coats for full coverage and an even color.
• It doesn’t adhere quite as well to metal as enamel without proper priming first.

With proper prep and application, latex can adhere well and provide a durable finish on a metal filing cabinet. The key is using high quality latex paint designed for metal, and properly preparing the surface.

Choose the Right Type of Latex Paint

Not all latex paints are created equal when it comes to metal. Here are some things to look for:

• 100% Acrylic – Paints labeled “100% acrylic” will last longer than cheaper vinyl acrylic paints. Acrylic offers better adhesion and durability.
• Direct-to-Metal Paint – Some brands offer latex paints formulated specifically for use on metal surfaces without a separate primer. These include rust-inhibitive properties to protect metal.
• Gloss Finish – For metal filing cabinets, a satin, semi-gloss, or high gloss sheen is best. Glossier paints are tougher and easier to clean.

Some top-quality 100% acrylic options include Rust-Oleum Painter’s Touch, Krylon Fusion All-In-One, and Zinsser PermaWhite.

Proper Metal Surface Prep is Crucial

No paint will adhere well to a metal filing cabinet unless the surface is prepared properly first. Here are the key steps:

• Clean – Wipe down the filing cabinet with mineral spirits to remove any oil, grease, or other contaminants.
• Sand – Use 120-150 grit sandpaper to scuff up the surface. This helps paint adhere better.
• Prime – Apply a universal metal primer like Rust-Oleum Painter’s Touch primer before painting. Priming provides extra corrosion resistance and paint adhesion.
• Degrease Again – Wipe cabinet with mineral spirits again after sanding to remove any residue.

Proper surface prep removes any glossy sheen and gives the latex paint something to “grab” onto. Rushing this step can lead to peeling or chipping paint down the road.

Application Tips for Success

Once prepped, follow these tips when applying latex paint:

• If the filing cabinet was previously painted, you may need to sand down areas with peeling paint. Use a wire brush attachment on a power drill for badly peeling paint. Completely remove rust with sandpaper.
• Apply paint in thin, even coats using a high-quality brush, roller, or paint sprayer. Thin coats provide better adhesion than thick coats.
• Allow proper dry time between coats as recommended by the manufacturer, usually 1-3 hours.
• Two to three coats ensures full coverage and protection. The primer coat counts as one.
• Maintain a wet edge as you paint and avoid lap marks by completing sections in one go from start to finish.

Maintaining the Finish

Once completely dry, a good quality latex paint can provide a durable finish on a metal filing cabinet. To keep it looking its best:

• Allow paint to cure fully, which takes about 2 weeks. Avoid cleaning or placing anything on paint until fully cured.
• Clean painted metal with mild soap and water. Avoid abrasive cleaners.
• Touch up any nicks or scratches immediately to prevent moisture getting under the paint.

With the right prep and application, latex paints can perform quite well on metal filing cabinets. Just be sure to use a 100% acrylic formulated for metal use. Proper priming and prep establishes a strong paint bond that should hold up for years with proper care. Latex provides an attractive, modern finish option for metal filing cabinets.

Frequently Asked Questions About Latex Paint on Metal Filing Cabinets

Can all latex paints be used on metal?

No, not all latex paints will adhere well to metal. For best results, choose a 100% acrylic latex formulation specifically made for metal surfaces, such as Rust-Oleum Painter’s Touch or Krylon Fusion. Cheaper vinyl acrylic paints don’t bond as well.

Do you have to primer before painting a filing cabinet with latex paint?

Yes, always prime metal before painting, even with paints claiming “no primer needed.” The primer coats the metal to prevent corrosion and provides extra adhesion for the latex topcoats. Always use a metal primer made for latex paint.

How long does latex paint take to dry on a metal filing cabinet?

At 70°F and 50% humidity, latex paint will be dry to the touch in 1-2 hours. Recoat time is usually 2-4 hours. Full curing takes approximately 14 days. Cooler temps or higher humidity slow dry times.

How many coats of latex paint for a filing cabinet?

Most quality latex paints will provide full coverage in 2-3 coats. The primer coat counts as one coat. Thinner coats provide better adhesion than thick coats.

Should I sand the filing cabinet before priming and painting?

Lightly scuff sanding with 120-150 grit sandpaper is recommended before priming and painting metal. This helps the paint grip the slick metal surface better. Always clean with mineral spirits after sanding.

How do I get a smooth finish with latex paint on a filing cabinet?

Use a high density foam roller and apply thin coats. Allow proper dry time between coats. Sand lightly with fine 220 grit sandpaper between coats to smooth brush marks if needed.

What sheen of latex paint is best for a metal filing cabinet?

Satin, semi-gloss, and high-gloss sheens are best for durability. Glossier paints are easier to clean. Flat or matte finishes can work but don’t hold up as well.

Conclusion

Latex paints have come a long way in performance and can be used successfully on metal filing cabinets. The keys are using a high quality 100% acrylic latex paint designed specifically for metal, properly preparing the surface, priming, and applying thin even coats. With some diligence on surface prep and application, latex paints can provide a tough and attractive finish comparable to enamels. Just be sure to follow best practices outlined above for preparations and application when using latex paint on metal filing cabinets.
