• Easier than replacing – No need to remove the cabinet and install a new one. Just paint right over the existing cabinet for a fresh look.
• Environmentally friendly – Reusing an existing cabinet is better for the environment than manufacturing a new one.

Painting an old metal sink cabinet lets you update the look of your space quickly and affordably while avoiding the hassle of a full replacement.

What Type of Paint to Use on Metal Cabinets

Choosing the right type of paint is critical for achieving a smooth, durable finish on a metal cabinet. Using latex wall paint or an inadequate primer will likely lead to chipping, cracking, or peeling down the road.

The two best paint options for cabinets are:

Enamel paint

Enamel paint (also called alkyd paint) provides a hard, glossy finish that resists chipping and stands up well to moisture and daily wear and tear. It dries harder than latex paint. Enamel works best for painting cabinets and other utilitarian metal surfaces like file cabinets or shelving.

Acrylic latex cabinet paint

Acrylic latex paints engineered specifically for cabinets offer a smooth, consistent finish. The acrylic in the paint provides flexibility to expand and contract with the metal cabinet without cracking. Latex cabinet paints are available in various sheens from gloss to matte.

Other paint considerations:

• Sheen – Semi-gloss is ideal for cabinets. It resists moisture and stains but isn’t as shiny as gloss. Satin finishes hide imperfections well.
• Color – Opt for light, bright, or neutral colors which give a sense of cleanliness for kitchens and baths. Bold colors work for other spaces.
• Quality – Invest in premium quality paints from reliable brands. They offer better coverage and durability than economy paints.

How to Prep an Old Metal Sink Cabinet for Painting

Preparing an old metal sink cabinet properly is the most vital step for achieving great painted results. Taking time to clean, sand, and prime will allow the new paint to adhere correctly.

Clean and degrease the cabinet

Use a degreasing cleaner or solution to thoroughly clean all surfaces of the cabinet. Scrub with an abrasive sponge or brush. This removes built-up grime, oils, soap residue, and any waxy buildup. Rinse surfaces well.

Tip: For extremely dirty cabinets, use a solution of TSP (trisodium phosphate) and water to cut through stubborn grease.

Sand surfaces

Lightly scuff sand all surfaces with 220 grit sandpaper. This roughs up the glossy metal finish so the primer and paint can adhere properly. Be sure to sand inside drawers and cabinet doors as well.

Tip: Use fine sandpaper and a sanding block for hard-to-reach curves and edges. Wipe away all sanding dust.

Use metal primer

Priming provides an essential foundation before painting metal. Use a high-quality metal primer specifically designed for use on metal cabinets and doors. The primer creates a barrier between the cabinet and paint.

Thoroughly apply 2-3 coats of primer, allowing proper drying time between coats according to the primer label. The primer ensures the paint sticks tightly to the slick metal surface.

Tip: For best results, choose a primer made by the same manufacturer as the paint you’ll be using. Companies formulate their primer and paint to work together.

How to Paint a Metal Sink Cabinet

Once your prep work is complete, you’re ready to apply new paint for a gorgeous makeover. Follow these best practices for painting the cabinet:

1. Work in a dust-free area

Paint small dust particles in the air can settle onto the wet paint as you work, creating a rough texture. Set up your workspace in a dust-free garage or basement if possible. Or drape drop cloths on the floor and over countertops.

2. Apply painter’s tape

Use painter’s tape to mask off any areas you don’t want painted, like the wall behind the cabinet or any adjacent cabinets and drawers. Remove all handles and hardware if possible.

3. Use good paintbrushes

Invest in premium angled trim brushes made for painting cabinets and woodwork. Avoid cheap, stiff bristle brushes that can leave obvious brush marks. Purdy and Wooster make excellent cabinet paint brushes.

4. Work systematically

Paint the cabinet frame, then the door panels, then drawer fronts. Paint the inside of cabinet doors separately before reattaching them. Maintain wet edges as you paint.

5. Apply multiple thin coats

Apply at least 3-4 thin, even coats of paint rather than one or two thick coats. Thin coats create a smoother finish. Allow proper drying time between coats. Lightly sand with fine sandpaper between coats for the best results.

6. Paint doors horizontally

Lay cabinet doors on sawhorses to paint them. Painting them vertically risks paint running or dripping down the door. Let doors dry completely before reattaching them.

7. Remove tape promptly

Carefully remove painter’s tape promptly after painting while the final coat is still wet. Letting tape sit causes the edges to dry and peel up when you remove the tape.

8. Allow a full cure time

Latex paints take 1-2 weeks to fully cure and harden. Avoid closing doors or putting back sink bowls during this time. The paint is softest during this period before completely hardening.

How to Seal and Protect the Painted Metal Cabinet

Applying a clear protective topcoat over painted metal provides an added layer of durable protection. The clear sealer binds to the dried paint and creates a uniform glossy coat. Polyurethane is the best choice for sealing a painted cabinet.

When to apply the topcoat

The protective clear topcoat can be applied after the final paint coat has dried for 24 hours. Make sure all paint coats are fully dry first.

How to apply polyurethane

Use a high-quality polyurethane formulated for use on painted wood cabinets. Carefully follow the product directions for best results. Apply using a clean foam brush or lint-free rag. Allow proper drying time between multiple coats. Lightly sand with fine grit sandpaper between coats for a smooth finish.

Cure time

Allow 5-7 days cure time for the polyurethane sealer before putting the cabinet back into use. The coating needs time to fully harden and develop its protective qualities. Treat the freshly painted cabinet gently during this period.

Sealing the painted metal cabinet gives it an extra layer of protection and a glossy finished look.

Tips for Achieving the Best Painted Metal Finish

Follow these pro tips to get that smooth factory finish look when painting metal cabinets:

• Always clean and sand metal properly before priming. This allows for maximum paint adhesion.
• Apply painter’s tape with a gap at edges for the cleanest paint lines. Taping flush creates seepage under the tape edge.
• Work in thin, multiple coats of paint rather than thick coats which can sag and run.
• Maintain a wet edge by brushing out from tacky edges into newly painted areas. This avoids lap marks.
• Lightly sand painted surfaces with fine (220-400 grit) sandpaper between every coat for minor imperfections.
• Allow proper curing times between coats. Drying and curing are not the same thing. Proper curing results in a harder finish.
• Use high quality trim brushes made for fine paintwork and cabinetry. Purdy or Wooster brushes work beautifully.
• Work in a clean, dust-free area to prevent dust nibs in the finish.
• Seal painted metal cabinets with 2-3 coats of protective polyurethane for added durability and sheen.

Common Questions About Painting Metal Cabinets

Many homeowners have additional questions when starting a project of painting metal cabinets and surfaces. Here are answers to some of the most frequently asked questions.

Can you use latex paint on metal cabinets?

Latex paints don’t adhere as tightly to slick metal surfaces as enamels and metal-specific paints. However, high quality acrylic latex cabinet paint will still work if the metal is properly sanded and primed first. Opt for paint with adhesion promoters formulated for metal.

What sheen is best for painting cabinets?

A satin, semi-gloss, or gloss sheen provides the most durable and scrubbable finish for cabinets. However, small imperfections will show more in high gloss. Satin or semi-gloss offer nice compromises between durability and hiding minor flaws.

How do you soften brush marks in painted cabinets?

To minimize visible brush strokes, use high quality trim brushes, apply paint in thin coats, and lightly sand between coats with fine sandpaper to feather out the edges of strokes. Using small foam rollers for flat areas also helps blend out brush marks.

Should you remove cabinet doors before painting?

It’s generally best to remove doors, drawers, handles and other hardware before painting cabinets. This allows for easier access to all surfaces and avoids getting paint on the hardware pieces. Lay doors flat to paint.

How long does it take for cabinet paint to cure?

Oil-based cabinet paints cure within 5-7 days, while latex acrylic cabinet paints take up to 2 weeks to fully cure and harden. Avoid closing doors or placing heavy bowls during this period while paint is at its softest.

Transform Your Metal Cabinets with Paint

Outdated metal cabinets quickly get a makeover with some simple paint techniques. Proper cleaning, sanding, priming, and painting transforms their look. With some effort and patience, you can paint your metal sink cabinet and other kitchen or bathroom cabinets to give them new life.

The finished results will look like new custom cabinetry at only a fraction of the cost. You can do the project over a weekend with these techniques for durable, beautiful results. With a fresh coat of paint in your choice of color, you can update your space with just the metal cabinets you already have.

Additional Tips for Painting Metal Cabinets

When Sanding Old Paint, Use Proper Safety Gear

If you are sanding a metal cabinet that has old paint or finishes, be very careful. Old paints often contain lead, which is extremely toxic. Always wear safety goggles, gloves, and a respirator mask when sanding any surfaces that may contain lead paint. Work in a well-ventilated area and contain dust. Properly dispose of contaminated rags, sandpaper, and any paint chips.

Test old paint for lead content before sanding using lead testing kits. Take proper precautions to protect yourself and your family from lead exposure, which can cause serious health issues. Safety comes first when preparing metal cabinets for new paint.

How to Achieve an Antique or Weathered Look

For a unique vintage style, try distressing new paint on a metal cabinet to mimic an antique patina or weathered look. Here’s how:

After priming and painting the cabinet, allow the top coat to partially cure for just 1-2 days. Then use fine sandpaper or steel wool to rub away paint in areas you want to show wear – like edges, handles, and raised areas.

Focus on creating smooth, gradual wear rather than large scratches or gouges. Finish by applying a dark glaze over the sanded areas to antiquing powder to further accentuate texture and aging. Finally apply a protective clear coat over the painted and distressed cabinet.

When Spray Painting, Use Outside With Drop Cloths

While brush painting cabinets is most common, you can use spray cans for a smooth, seamless finish. If spray painting, always work outside or in a fully protected area. Cover all nearby surfaces with plastic drop cloths. Spray in steady back-and-forth strokes with slight overlap, maintaining equal distance from the cabinet.

Thin coats work better than one heavy coat. Allow proper drying times between coats. Follow all safety precautions when using spray paints. Proper ventilation and a respirator mask are essential.

How to Paint Interior Surfaces

Use small trim brushes and foam mini rollers to thoroughly paint interior cabinet surfaces. Thoroughly clean and prime these areas first before painting. For easier access, remove adjustable shelves. Use painter’s tape to cover nearby surfaces from overspray if using spray paint for interiors.

Cleanup Tips

After painting, promptly wash brushes in the appropriate thinner – either water for latex paints or paint thinner/mineral spirits for oil-based. Use soap and water to wash any paint from your hands or surfaces. Cooking oil removes stubborn paint residue from skin. Avoid flat razor blades – they scratch. Use plastic paint scrapers.

Painting Metal Cabinets in Bathrooms vs. Kitchens

Painting metal cabinets in kitchens and bathrooms require some slightly different considerations due to the different uses, moisture levels, and wear and tear in each space.

Kitchen Cabinet Painting Tips

The kitchen sees high traffic and cooking splatters and spills. Follow these tips for durable kitchen cabinet paint:

• Opt for oil-based enamel or a high grade urethane acrylic latex designed specifically for kitchen cabinet use. These durable finishes stand up well to kitchen conditions.
• Use satin, semi-gloss, or gloss sheens rather than flat or matte. Glossier finishes resist moisture, grease, and dirt buildup.
• Include heat-resistant additives if painting cabinets near stoves and ovens to avoid cracking or peeling from high temperatures.
• Seal painted surfaces with non-yellowing clear polyurethane for added protection and easy cleaning.
• Avoid darker colors which show grease spatters, dirt, and wear more easily. Cream, white, or lighter wood tones hide kitchen grime the best.

Bathroom Cabinet Painting Tips

Painting metal cabinets in humid bathroom environments also requires special considerations:

• Make sure metal surfaces are completely clean and dry first. Degrease thoroughly to remove soap buildup and hard water residue.
• Opt for mold/mildew resistant latex paints that stand up to moisture. Oil based enamels also work well.
• Use satin or semi-gloss sheens for paint and topcoat sealer. Higher sheens withstand humidity better than flat paints.
• Make sure substrate is fully primed to prevent corrosion under new paint. Prime bare metal areas extremely well.
• Include silicone additives to improve flow and assist with moisture resistance.
• Avoid glossy finishes which highlight uneven drywall texture from steam. Opt for subtle sheens instead.
• Ensure the bathroom has proper ventilation to avoid excess moisture. Address any existing mold concerns before painting.

Troubleshooting Common Paint Problems on Metal Cabinets

Even when carefully prepped and painted, metal cabinets can develop problems like chipping, cracking, or bubbling paint. Here are some common paint issues and how to fix them.

Problem: Paint Chipping or Peeling

Solution: If paint chips down to the metal shortly after painting, the cause is likely inadequate prep, primer, or paint. Thoroughly remove all loose paint down to the metal. Clean, sand, and reprime before repainting. Use high quality metal-specific primer and paints engineered for metal. Acid etching primer also helps paint bind tightly.

Problem: Paint Bubbles or Blisters

Solution: Blistering under the paint happens when moisture is trapped and pushes up the paint. The metal likely wasn’t properly cleaned and dried first. Blisters must be sanded down, then area reprimed and repainted. Always thoroughly prepare metal before painting.

Problem: Cracking or Alligatoring

Solution: If new paint cracks into small segments resembling alligator skin, the cause is applying paint too thick. Several factors like high temperatures or humidity can also cause cracking. Lightly sand crackled areas down to sound paint. Ensure proper film thickness when repainting in smooth, thin coats.

Problem: Brush Marks Showing Through Paint

Solution: Visible brush strokes come from using low-quality brushes, applying paint too thick, or improper drying between coats. Lightly sand problem areas and repaint using high quality trim brushes. Apply paint in thinner coats. Allow proper drying times between coats.

Problem: Discoloration or Fading

Solution: Metal paints can yellow or fade over time with sun exposure or heat. Remove failing paint completely with removers or sanders. For stain-blocking, prime with a white shellac based primer before repainting
