- Tarp/drop cloths: To cover floors and protect surfaces.
- Painters tape
- Paint thinner/mineral spirits: For cleanup
- Rags and paper towels
- Face mask: Look for one rated for paint spraying to protect from overspray.
- Disposable gloves and eye protection
Preparing the Workspace
Here are some tips for setting up your workspace when spray painting a cabinet:
Ventilation
- Work in a well-ventilated area – outdoors is ideal if possible. If working indoors, open windows and use fans to direct airflow away from you.
Cover Floors and Surfaces
- Use a tarp or drop cloths to cover the floor around the cabinet to protect from paint drips.
- Cover any surfaces near the cabinet with plastic sheeting as well.
- If needed, you can use extra cardboard to mask walls or surfaces behind the cabinet.
Have Clean Rags Ready
- Have plenty of clean rags, paper towels and thinner/mineral spirits nearby to quickly wipe up drips or errors.
Prepare the Cabinet
- Remove cabinet doors and drawers to make spraying easier. Also remove any hardware like knobs or handles.
- Place the empty cabinet shell on top of cardboard or blocks to raise it off the tarp/dropcloth.
Cleaning and Prepping the Cabinet
Proper prep work is crucial for the spray paint to adhere correctly. Here’s how to prepare a metal cabinet for painting:
- Wipe down the cabinet with mineral spirits to clean and degrease the surface.
- Lightly sand the cabinet using 220 grit sandpaper. This helps the paint bind better.
- Dust off the cabinet and wipe it down again with a tack cloth.
- Apply painter’s tape around edges and hardware holes to protect those areas from overspray.
- Use a screwdriver to remove any loose paint or rust spots. Hit stubborn areas gently with sandpaper.
- Fill any holes, dents or gouges with metal filler compound and let dry completely. Sand smooth.
This prep ensures you’ll have a clean, uniform surface for the primer and paint to adhere to.
Applying Primer and Letting Dry
After proper cleaning and sanding, it’s time to apply primer:
- Use a high quality metal primer suited for your paint sprayer. Primers help provide better adhesion.
- Apply a light first coat of primer, spraying back and forth to get uniform coverage. Avoid runs or drips.
- Let the primer dry completely. Check manufacturer instructions for exact drying times.
- Once fully dry, you can lightly sand any rough spots with fine (400 grit) sandpaper.
- Wipe down the surface with a tack cloth again to remove any dust.
- Apply a second coat of primer in thin, even passes.
- Allow the primer to fully dry again before moving onto painting.
Priming is a crucial step, so don’t skip over it. Taking your time leads to better looking final results.
Spray Painting Technique
Here’s how to properly spray paint your primed metal cabinet:
1. Choose a Paint Designed for Metal
Look for acrylic enamel spray paints specifically formulated for metal surfaces. The paint should indicate “highly adhesion promotion” or note that it’s for metal on the label.
2. Shake the Can Well Before Starting
Make sure to thoroughly shake and agitate spray paint cans per the directions. This mixes up pigments that may have settled.
3. Work in Thin, Even Coats
Apply the spray paint front-to-back and left-to-right in a sweeping motion about 8-10 inches from the surface. Move the can, not just your wrist, as you spray.
Work in thin coats, spraying back and forth to build up even coverage. Let each coat fully dry before adding another.
4. Get Proper Pattern Overlap
Overlap each paint pass 30-50% to create a uniform appearance. Avoid holding the can in one place too long or you’ll get drips.
5. Spray the Trim Areas First
Paint all the detailed trim/molding areas first. Then fill in the center flat portions. This prevents paint build up in corners.
6. Check for Drips and Runs
Inspect between coats for any drips forming and wipe them away immediately with mineral spirits.
7. Spray Additional Topcoats
Apply at least 2-3 topcoats for full coverage and an even color. Lightly sand then add topcoats to create a smooth finish.
Take your time with multiple light coats. This leads to a professional sprayed-on look.
Applying Sealers/Topcoats
For added protection and durability, you’ll want to apply 1-2 coats of a clear acrylic sealer or topcoat after the paint has dried:
- Use an acrylic enamel clear coat meant for spray application on metal.
- This helps protect the painted surface from potential scratches, dings, grease splatter and other damage.
- Apply using thin, even passes like you did with the paint.
- Multiple thin topcoats are better than one thick one for an even appearance.
- Let the sealer fully dry and cure per manufacturer directions before using the cabinet.
The topcoat helps the pristine paint job you just did last for many years!
Cleaning Up Properly
Here are some tips for proper cleanup after your cabinet spray painting project:
- Wipe up all paint drips right away before they dry using mineral spirits.
- Use paint thinner to clean your paint sprayer system thoroughly after use. This prevents clogs.
- Properly dispose of all used rags, drop cloths and other paint contaminated items. Allow to fully dry first before throwing out.
- If using spray cans, turn them upside down and spray until the spray is fully clear to clear the nozzle.
- Do a final wipe down of the work area and freshly painted cabinet to remove all paint dust and debris.
- Remove any painter’s tape once the final coat has dried. Pull slowly at a 45° angle.
- Replace all hardware and reattach cabinet doors/drawers once fully dry.
Taking time to properly clean up will leave your work area neat and your sprayer ready for future projects.
Frequently Asked Questions About Spray Painting Metal Cabinets
Here are answers to some common questions about prepping and spray painting metal cabinets:
What kind of sprayer is best for cabinets?
You can use either aerosol spray paint cans or an airless spray gun. Aerosol cans are easier for DIY-ers, provide good coverage and often have primers included. Airless sprayers require more skill but provide the most uniform finish.
How long does spray paint take to dry?
Most spray paint dries to the touch in 30-60 minutes. But allow extra time for metal – check the manufacturer instructions. Drying may take 1-2 hours between coats. It takes 4-7 full days to fully cure and harden.
Should I remove cabinet doors when painting?
Yes, you should remove any doors and drawers from the cabinet and paint separately for the easiest access to all surfaces. Remove any hardware as well.
What’s the best way to prep the surface?
Lightly scuff sand the cabinet with 220 grit sandpaper to help the paint adhere. Then wipe down with mineral spirits and a tack cloth before priming.
Can I spray paint over rust?
For best results, remove any loose paint and sand down any rust spots before priming and painting the cabinet. Rust continues damaging the metal underneath unless removed.
How do I get a smooth finish?
Applying multiple thin coats leads to a smooth appearance. Lightly sanding between coats also helps. Don’t spray too thick or you’ll get drips.
How long does it take to fully spray paint a cabinet?
Plan on the project taking 2-3 full days between proper prep work, 2 coats of primer, 3-4 coats of paint, and 1-2 coats of a clear sealer. Rushing leads to a poor finish.

How to Choose the Right Spray Paint for Metal Cabinets
When taking on a spray paint project for metal cabinets, having the right kind of spray paint is key to getting great results. With all the options out there, it can be tricky figuring out which specific spray paint formulas work best.
Follow this guide to learn about the important factors in choosing a spray paint for metal and pick the best product for flawlessly painting cabinets, doors, and other metal furniture:
Pick a Paint Made Specifically for Metal
- Look for spray paints labeled specifically for metal, steel, iron or aluminum use. These contain resins and binders that adhere best to slick non-porous metal.
- Avoid standard spray paints for wood, plastic or general purposes. The adhesion and flexibility on metal will be poor.
- The label should mention metal, high adhesion, or have an image showing it’s intended for metal/iron.
Choose an Enamel Based Spray Paint
- Acrylic enamels are preferred for painting metal versus standard acrylic, lacquer or other options.
- Enamel paints provide an extra tough, scratch resistant finish with a smooth surface.
- The coating flexibility prevents cracking, chipping or peeling on metal cabinets.
Match the Paint to Your Surface – Galvanized or Non-Galvanized Metal
- Galvanized metal has a zinc coating while non-galvanized does not.
- Choose paint specifically made for galvanized metal if your cabinets have a shiny, lightly textured surface.
- For bare steel, iron or aluminum cabinetry, select paint for non-galvanized metal.
Ensure Maximum Adhesion Strength
- Adhesion promoter in the spray paint helps it bond tightly to slick metal.
- Look for phrases like “maximum adhesion” or “excellent adhesion” on enamel spray paint for metal use.
- Shake the can vigorously before use to fully mix the adhesion promoting additives.
Consider Temperature Resistance
- Look for spray paint formulated to withstand high temps if painting cabinets around ovens, grills or other heat sources.
- High heat spray paints withstand temps up to 1200°F. This prevents discoloration or peeling.
Match Your Application Method
- Certain spray paints are designed for aerosol cans while others work best for HVLP spray gun use.
- Buy paint intended for your application method for ideal spraying consistency and results.
Choose Between Matte, Glossy or Satin Finish
- Glossy enamel spray paints offer the most vibrant color and easiest cleaning but show imperfections.
- Matte finishes hide flaws better but are prone to scuffs and stains.
- Popular satin finishes split the difference with muted shine and decent durability.
Buy From a Trusted Brand
- Stick with reputable spray paint brands like Rust-oleum, Krylon, Dupli-Color or Montana to ensure quality.
- Avoid no-name bargain brands which may have less pigment or weaker adhesion properties.
Now that you know what to look for, you can choose the best spray paint for your specific metal cabinet painting project. With high adhesion enamel paint made for metal use, you’ll get outstanding results from start to finish.
How to Prime Metal Cabinets Before Spray Painting
Applying primer is one of the most important steps before spray painting metal cabinets. Priming creates a uniform surface for the paint to stick to while also preventing rust and corrosion down the line. Here’s a walkthrough on how to properly prime metal cabinets and get great results:
Sand the Metal Surface
- Lightly sanding the cabinets prior to priming allows for better adhesion.
- Use 220-400 grit sandpaper to scuff up the surface. This roughs up the top layer.
- Sand just enough to scratch the surface, not try to strip it down fully.
- Wipe away all sanding residue with a tack cloth once done.
Clean With Solvents
- Use denatured alcohol, acetone or lacquer thinner to fully degrease the metal.
- Proper cleaning removes any oils, wax or dirt so the primer binds well.
- Let the metal fully dry after cleaning before moving ahead with priming.
Apply the First Coat of Primer
- Look for primers specifically made for metal when choosing your product.
- Use long, even strokes and spray from about 8 inches away from the surface.
- Multiple thin coats are better than one thick coat for an even finish.
- Spray the primer onto all cabinet surfaces – sides, fronts, backs, and doors.
Allow Primer to Dry
- It’s important to let the first coat fully dry before adding another one.
- Most primers take about 2 hours to dry on metal cabinets. Check your product label.
- Proceed once the primer has hardened and does not feel tacky to the touch.
Apply the Second Coat of Primer
- Lightly scuff sand the first coat with 400 grit sandpaper before the next coat.
- Apply the second coat of primer vertically if your first coat was horizontal, and vice versa.
- The goal is to cover any spots that were potentially missed the first time.
- Let the second coat dry fully as well before moving onto painting.
Inspect for Missed Areas
- Look closely for any bare metal spots that need touched up after the second coat has dried.
- Spot prime any places that need more coverage and let dry again.
- Proper priming takes patience but prevents unfinished looks later on.
Now you can move onto spray painting your perfectly primed metal cabinets with confidence!
How to Fix Paint Drips When Spray Painting Cabinets
It’s easy for paint drips and runs to occur when spray painting kitchen or bathroom cabinets. Luckily, catching them in time means they can be fixed. Follow these tips to fix paint drips when spray painting metal or wood cabinets:
Inspect Between Coats
- Closely examine for drips forming after applying each coat of paint.
- Keep paint rags handy to wipe up drips while the paint is still wet.
- Look in corners, edges and wherever paint can pool up and drip.
Work Quickly
- Have mineral spirits ready to wet your rag and wipe drips immediately before they dry.
- The quicker you catch drips, the easier they’ll be to fix.
Lightly Sand Dried Drips
- For drips that have already dried, use 220 grit sandpaper to gently smooth them down.
- Take care not to sand down to the bare substrate. Just sand enough to level the drip.
Spot Apply Primer
- For areas you sanded down to the bare metal or wood, re-apply primer to that spot before painting again.
- This prevents the paint from absorbing differently leading to visible flaws.
Adjust Your Painting Technique
- To prevent future drips, hold the paint sprayer closer and move it faster side to side.
- Focus on making quicker, thinner passes rather than over-applying in one spot.
Consider Using Brushes for Problem Areas
- Use high quality tapered trim paint brushes for corners and edges prone to drips.
- Careful brushwork can help prevent drips in problem areas.
Apply Lighter Topcoats
- Drips become less visible under lighter topcoat layers. Don’t spray heavy coats on top of drips.
- Multiple thin, even coats blend everything together for a seamless appearance.
Stay vigilant for drips during your project and you can keep cabinet paint jobs looking pro quality.
