Restoring old metal cabinets can breathe new life into dated kitchens, bathrooms, garages, and other spaces. With some cleaning, painting, and hardware upgrades, you can make those worn-out metal cabinets look brand new again. This comprehensive guide will walk you through all the steps needed to revitalize tired metal cabinets.
Assessing Your Old Metal Cabinets
Before determining the restoration process, thoroughly examine the current state of your old metal cabinets. Check for these common issues:
Fading and Discoloration
Over time, metal cabinet paint can fade, yellow, or develop rust stains. Make note of any visible color changes. You’ll need to sand down areas with fading, peeling, or uneven paint so the new paint coat adheres properly.
Dents and Dings
Old metal cabinets accumulate plenty of dents, scratches, and dings through decades of use. Run your hand along each cabinet to feel for any damaged spots. Use filler compound to smooth dents before repainting.
Rust
Exposure to moisture causes metal cabinets to rust, especially around hinges, handles, and edges. Check the backside and interior of cabinets for rust spots. Remove all rust prior to painting to prevent further spreading.
Loose Hinges and Doors
Cabinet hinges weaken over time, causing doors to sag. Test each door to see if it freely opens and shuts. Tighten any loose hinge screws. Consider replacing old hinges completely.
Damaged Hardware
Examine all cabinet hardware like handles, latches, knobs, and pulls. Make note of any missing, loose, or corroded pieces. Replace any hardware that looks worn or functions poorly.
Gather Supplies for the Restoration Project
With an assessment of your cabinets’ current condition complete, compile all the necessary supplies to restore old metal cabinets:
- Sandpaper – Coarse 80-100 grit for heavy sanding, fine 220-400 grit for smoothing.
- Paintbrush and paint roller – For applying primer and paint coats. Foam rollers work best for smooth metal.
- Metal primer – Primes bare metal for paint adhesion.
- Metal paint – Durable acrylic or enamel formulas resist chipping and scratching.
- Filler compound – Spackling paste and putty fill dents, holes, and uneven spots.
- Rust remover – Removes rust stains from metal surface.
- Tack cloth – Lifts dust between sanding and painting.
- Drop cloths – Protect floors and countertops from paint drips.
- Cabinet hardware – Knobs, pulls, hinges and associated hardware.
Gather all supplies prior to starting your metal cabinet restoration to ensure an efficient process from start to finish.
Cleaning Metal Cabinets Prior to Restoration
Before painting or making any repairs, thoroughly clean all cabinet surfaces:
- Remove cabinet doors and drawers to access the interior, sides, and exterior surfaces.
- Wash all surfaces with a degreasing cleaner or dish soap. Rinse away all soap residue.
- Use a mildew remover if you see any mold or mildew growth. Scrub the area and rinse clean.
- For stubborn dirt or grease, use a TSP substitute cleaner. Wear gloves and follow product directions.
- Scour rust stains with a rust remover gel and non-abrasive scrubbing pad.
- Dry all cabinets completely once cleaned. Allow a day or two for the metal to fully dry.
Proper cleaning removes grime and grease buildup so new paint properly adheres to the metal surface.
Sanding Metal Cabinets Prior to Painting
Once your metal cabinets are clean and dry, sand down all surfaces in preparation for primer and paint.
Sanding Process
- Start sanding using 80-100 grit sandpaper for the heavy sanding stage.
- Sand in the direction of the metal grain to avoid deep scratch marks.
- Concentrate on areas with rust, peeling paint, or glossy finishes.
- Use fine 220-400 grit paper for the final smoothing stage.
- Sand edges and hard to reach crevices by hand. Use a sanding block for broad surfaces.
- Wipe away all sanding dust with a dry cloth after finishing.
Safety Tips
- Wear a protective face mask to avoid inhaling fine metal and paint dust.
- Work in a well-ventilated area and use a shop vacuum for dust containment.
- Use eye protection to prevent metal shards from damaging your eyes.
Thorough sanding helps new primer and paint bond tightly. Take safety precautions when sanding metal to avoid inhaling dangerous dust.
Filling Holes and Imperfections
Use filler compound to patch holes, dents, gouges, seams, and other damaged areas:
- Dig out any exposed rust spots with a putty knife before filling.
- Apply filler compound over the flaw and use a putty knife to smooth it out.
- Let filler dry completely then sand flush with the surrounding surface.
- Repeat filler application and sanding if the repaired spot remains visible.
- Use spackling paste for small holes and lightweight wood filler for deeper defects.
- Allow proper dry time for your selected filler according to the manufacturer directions.
Filling imperfections in your metal cabinets produces an ultra-smooth surface for painting. Take your time prepping so your painted cabinets look profession when complete.
Priming Metal Cabinets
After proper cleaning, sanding, and filling, use a metal primer specifically designed for use on metal surfaces before applying cabinet paint:
Selecting Metal Primer
- Opt for a rust-inhibiting primer for ultimate corrosion protection.
- Choose a fast-drying formula to save time between coats.
- For the smoothest finish, select a high-fill primer to hide imperfections.
- Verify primer matches your paint sheen – satin, semi-gloss, etc.
Applying Primer
- Cover floors, countertops, and walls with drop cloths to protect surfaces.
- Wear gloves and ventilation mask to avoid direct skin and eye contact.
- Stir primer thoroughly before and periodically throughout the application process.
- Use a combination of brushing in recessed areas and rolling broad surfaces.
- Apply two thin coats of primer rather than one thick coat.
- Allow proper dry time between coats according to manufacturer guidelines.
Quality metal primer provides maximum paint adhesion and protects against future rust formation. Carefully follow all label instructions when applying.
Painting Metal Cabinets
With your cabinets cleaned, sanded, filled, and primed, you’re ready for the final painting stage:
Choosing Cabinet Paint
- Select durable enamel or acrylic paint designed for metal.
- Opt for satin, semi-gloss, or gloss sheen for washable finish.
- Purchase enough paint to apply 2-3 thin coats for full coverage.
Paint Application
- Lightly sand primed cabinets with fine grit sandpaper to improve paint adhesion.
- Wipe away all sanding dust with a tack cloth before painting.
- Carefully follow all paint instructions, stirring frequently during application.
- Apply using a combination of angled brush for corners and edges and small foam roller for broad areas.
- Allow proper dry time between coats based on product specifications.
- Finish with two to three thin coats for a smooth factory-like finish.
Curing and Dry Time
- Allow freshly painted cabinets 24-48 hours drying time before reinstalling doors and drawers.
- Leave cabinets undisturbed for two weeks to fully cure before regular use.
- Keep pets and children away from cabinets while paint fully hardens.
With quality materials and proper application techniques, your DIY painted metal cabinets will look brand new again!
Installing New Cabinet Hardware
Replacing worn-out hardware is the finishing touch to revive tired metal cabinets:
Selecting New Hardware
- Choose handles and knobs that align with your kitchen or bathroom style – modern, farmhouse, traditional, etc.
- Opt for durable hardware material like brushed nickel, chrome, bronze, or stainless steel.
- Take cabinet doors and drawers to the hardware store test sample pieces for size and fit.
Removing Old Hardware
- Number each door and drawer to match hardware placement when reinstalling.
- Use a Phillips-head screwdriver to remove old cabinet knobs and handles.
- For hinges, remove the hinge pins before prying off the brackets.
- Patch remaining hardware holes with filler compound and sand smooth.
Installing New Hardware
- Refer to the numbering system and reinstall new handles and knobs in their original location.
- Attach new hinges, keeping doors aligned and operational.
- Follow all manufacturer instructions for proper hardware installation.
Upgraded cabinet hardware gives your newly restored metal cabinets a cohesive finished look. Take time to select hardware pieces that match your overall kitchen or bathroom decor.
