Can You Use Chalk Paint on Metal Filing Cabinet?

Chalk paint has become an extremely popular choice for DIY furniture makeovers in recent years. Known for its matte finish and ability to adhere to surfaces with little prep, chalk paint can transform dated, worn furniture into stylish shabby chic pieces. But can you use chalk paint on metal surfaces like filing cabinets?

An Introduction to Chalk Paint

Chalk paint, also called mineral paint or milk paint, refers to a water-based paint made using chalk as a filler and binder. Unlike traditional latex or oil-based paints, chalk paint does not require sanding, priming, or sealing prior to application.

The main benefits of chalk paint include:

• Adheres to Most Surfaces – Can be used on wood, metal, glass, stone, concrete, plastics, laminates, and more with proper prep. Does not require sanding or priming.
• Matte Finish – Dries to a velvety, matte look instead of shiny or glossy. Great for achieving a worn, vintage aesthetic.
• Fast Drying – Can be recoated in just 30-60 minutes. Multiple coats can be applied in one day.
• Low Odor & VOC – Has little odor and releases almost no VOCs, making it safe for indoor use.
• Easy Soap & Water Cleanup – Chalk paint cleans up easily with just soap and water since it is water-based. No need for mineral spirits.
• Very Pigmented – Provides great coverage and often only needs 1-2 coats. Deep, rich colors.

The most popular brand of chalk paint is Annie Sloan, which comes in a wide range of colors. But chalk paint can also be purchased from brands like Americana Decor, Rust-Oleum, Southern Accents, and many others. It can also be made at home using chalk, plaster of paris, and paint.

Using Chalk Paint on Metal Surfaces

Chalk paint can generally be used on metal surfaces like filing cabinets, however, there are a few factors to consider:

Surface Preparation

Proper prep is key for the best adhesion. Start by cleaning the filing cabinet thoroughly with a degreaser to remove any dirt, oil or grease. Then lightly sand to rough up the surface and remove any loose paint or rust. Wipe away dust with a tack cloth.

For galvanized metal or non-ferrous metals like aluminum, first apply a coat of acrylic bonding primer to help the chalk paint adhere.

Rust Concerns

If there are areas of rust on the filing cabinet, these need to be addressed prior to painting. Use a wire brush to remove any loose, flaking rust. For heavy rust, use a rust converter primer like Rust-Oleum Rust Reformer to convert the rust into a paintable surface.

Smooth vs Textured Finish

Chalk paint dries to a velvety matte finish. If you want a smoother look, you can lightly sand between coats and finish with a sealing wax or lacquer. For a textured look, apply the paint thickly so brushstrokes are visible.

Durability

While very versatile, chalk paint provides a less durable finish than industrial enamels made for metal. The finish may be prone to chipping, scratching, or wearing down over time with heavy use. Applying a protective topcoat can help.

Color Coverage

Chalk paint is highly pigmented but opaque colors like reds, blacks, and browns may require extra coats for full coverage over light metal colors. Whites and off-whites generally provide great coverage.

Step-By-Step Guide to Painting a Metal Filing Cabinet with Chalk Paint

Painting a metal filing cabinet with chalk paint is an easy weekend project. Here are step-by-step instructions:

Supplies Needed

• Chalk paint in your color(s) of choice
• Sandpaper or sanding block (150 grit)
• Tack cloth
• Paint brushes – combination of wide brush for large surfaces and small trim brush
• Paint tray and stir stick
• Drop cloth or painter’s tape
• Acrylic bonding primer (for galvanized/aluminum cabinets)
• Clear wax or sealant (optional)

Prep Steps

1. Remove the drawers from the cabinet. Take off any attached hardware like handles or label holders. Remove any loose paint flakes or rust spots.
2. Clean the filing cabinet thoroughly using a degreaser or TSP substitute to remove any oils, waxes or grime. Rinse well and let dry fully.
3. Lightly sand the surfaces to rough them up and promote paint adhesion. Wipe away any dust with a tack cloth.
4. Apply a coat of acrylic bonding primer if the cabinet is made of galvanized metal or aluminum. Let the primer dry completely.
5. Use painter’s tape or drop cloths to mask off any nearby surfaces you don’t want to get painted.

Painting Steps

1. Stir the chalk paint well before starting. Pour some paint into a tray. Dip your brush in and wipe off excess paint against the side of the tray before applying to the surface.
2. Use a wide brush to paint the large flat surfaces using long, even strokes. Paint the sides and edges with a smaller trim brush.
3. Work in small sections applying a thin, even coat of chalk paint. Avoid over-brushing.
4. Let the paint dry 30-60 minutes before applying a second coat. Lightly sand between coats for a smoother finish.
5. Apply 1-2 additional coats until you achieve your desired color coverage. Allow the final coat to dry overnight.
6. Remove painter’s tape and reattach any hardware. Seal with wax or polyurethane for added protection if desired.
7. Reinstall the drawers and enjoy your updated filing cabinet!

Tips for Successfully Painting Metal with Chalk Paint

Follow these tips to ensure your chalk painted metal furniture or filing cabinet turns out well:

• Always do any necessary rust removal, sanding, and priming first. Proper prep is crucial.
• Apply thin coats and avoid over-brushing. Chalk paint can create a gummy texture if applied too thick.
• Let each coat dry thoroughly before adding the next coat. Follow the paint manufacturer’s recommended drying times.
• Mixing brands is not recommended. The formulations may not be compatible.
• For great coverage on dark colors over light metals, use a tinted primer or base coat in a similar color first.
• Seal the finished piece with wax or a water-based poly if it will get heavy use. This adds protection.
• Distress your piece after painting by lightly sanding edges or surface areas to achieve an antique, timeworn look. Apply dark wax glaze to recessed areas to accentuate.

Alternative Paint Options for Metal Furniture

While versatile, chalk paint is not the only option for painting metal filing cabinets and furniture. Here are a few other good paint choices:

Frequently Asked Questions About Using Chalk Paint on Metal

Can you use chalk paint on metal filing cabinets?

Yes, chalk paint can generally be used to paint metal filing cabinets, but may require additional preparation like light sanding and priming first for best results. The paint may be prone to chipping on surfaces that get a lot of wear.

Does chalk paint need a primer on metal?

Most chalk paint brands do not require a separate primer, but priming provides better adhesion. Use an acrylic bonding primer for non-ferrous metals like galvanized steel or aluminum. Rusty metal may need a converter primer.

How do you get a smooth finish with chalk paint?

For smoother results, lightly sand between coats with fine sandpaper. Finish with a sealing wax or water-based polyurethane coating. Avoid over-brushing the paint when applying.

Can you use chalk paint on rusty metal?

For best results, remove loose rust first then apply a rust converter primer to transform any remaining rust into an inert surface that can be painted over. The chalk paint alone will not stop existing rust from spreading.

Does chalk paint need to be sealed on metal?

Sealing is an optional step but recommended for metal surfaces that will get heavy wear. The sealant provides added protection against chipping, scratching and wear over time. Top coat with wax or water-based polyurethane.

Can chalk paint be used outdoors?

Chalk paint is intended for indoor use only. For outdoor metal furniture or surfaces, use a paint designed specifically for outdoor use that contains UV blockers and inhibitors to protect against sun damage and fading.

Achieve a Stylish Update with Chalk Painted Metal Furniture

With proper prep and application, chalk paint can give dated metal filing cabinets, furniture and accessories a quick and easy makeover. The soft, matte finish transforms the look from utilitarian to shabby chic with just a couple coats of paint.

Be sure to address any rust issues first, lightly sand the surface, and apply thin even coats allowing proper drying time between applications. Seal the piece if it will get heavy use. Then distress as desired to achieve that timeworn, antique look.

So try out chalk paint on your worn metal filing cabinets or furniture. With just a little time and effort, you can affordably achieve a stylish, updated look for your office or living space.
