How to Restore Old Metal Cabinets

Restoring old metal cabinets can breathe new life into outdated kitchens, pantries, and other living spaces. With some cleaning, sanding, priming, and fresh coats of paint, you can transform the look of your old metal cabinets without the high cost of full replacement. Follow this guide to restore metal cabinets to their former glory.

Clean Cabinets Thoroughly

The first step is to empty out the cabinets completely and clean all surfaces. Here’s how to clean metal cabinets properly:

• Remove all contents and shelves from cabinets. Set hardware like knobs and hinges aside for later reinstallation.
• Use a vacuum attachment or soft brush to remove any loose dirt, dust, or debris inside the cabinets.
• Mix a solution of warm water and dish soap in a spray bottle. Spray down all interior and exterior surfaces.
• Scrub all surfaces with a sponge or soft cloth. Pay close attention to greasy areas around knobs and handles.
• Rinse everything thoroughly with clean water and dry completely with a microfiber towel.
• Use a degreaser like Goo Gone for any remaining sticky or oily residue. Rinse and dry again.

Thorough cleaning removes built-up grime so that paint adheres well in later steps.

Sand Cabinets to Improve Paint Adhesion

Lightly sanding the cabinets smooths the existing finish and helps paint stick. Here’s how to sand metal cabinets:

• Use 100-150 grit sandpaper to scuff all interior and exterior surfaces. Always sand in the direction of the metal grain.
• Sand just enough to rough up the finish. Don’t sand down to bare metal.
• Use a tack cloth after sanding to remove any metal dust.
• Pay special attention to rust spots, chipping paint, or sharp edges. Sand these areas more to feather out flaws.
• Clean all surfaces again with a 50/50 vinegar and water solution after sanding. Rinse and let dry fully.

Proper sanding gives paint an optimal foundation to bond tightly.

Repair Damage and Apply Primer

Fix any damage and prime the cabinets so paint looks its best. Follow these steps:

• Use auto body filler to patch holes, dents, or rust spots. Allow filler to dry fully and sand smooth.
• Apply 2-3 thin coats of metal primer, allowing drying time between coats. Primer helps prevent future rust.
• Lightly sand again after the final primer coat to smooth any drips or rough patches.
• Carefully wipe away all dust with a tack cloth. Don’t touch surfaces with bare hands after this point.
• Use painter’s tape to mask off adjacent surfaces like walls or countertops. Remove any cabinet doors and hardware and prime separately.
• Spray all cabinet interiors, exteriors, edges, and doors evenly with primer. Backbrush for an ultra-smooth finish.

Primer creates the ideal foundation for your fresh paint color.

Choose a Durable Cabinet Paint

Picking the right paint ensures a long-lasting and uniform finish. Consider these tips for choosing paint:

• Opt for a high-quality acrylic latex enamel paint. Latex paints today offer excellent durability and are easy to apply.
• Semi-gloss or satin finishes are ideal for cabinets. They are shinier and more stain-resistant than flat finishes.
• Buy paint specifically formulated for metal. Metal surfaces require durable, rust-resistant paints.
• If you plan to paint doors in a darker shade than the cabinets, use an oil-based primer first. This prevents bleed-through.
• Purchase enough paint to complete the project with a spare can as back up. Having to mix more batches can lead to slight color variations.

Investing in top-quality metal paint leads to a flawless and lasting finish.

Apply New Paint in Thin, Even Coats

The key to a smooth, professional-looking paint job is applying several thin coats. Follow these tips:

• Stir paint thoroughly before and occasionally during use. Use a paint stick to reach the bottom.
• Paint in a dust-free area with adequate ventilation at around 70°F. These conditions allow for proper drying.
• Use a high-density foam roller and angled brush to coat all surfaces smoothly and evenly.
• Apply paint generously but not to the point of dripping or pooling. Spread in the direction of the metal grain.
• Allow at least 24 hours drying time between coats. Lightly sand again if any drips or bumps appear after drying.
• Apply at least 2-3 total coats for complete coverage and a uniform sheen. More coats may be needed for darker colors.
• Work methodically from top to bottom, doing all upper cabinets first. Pay extra attention to hard-to-reach nooks and edges.
• Remove masking and reinstall doors and hardware after 24 hours drying time on the final coat.

Patient, multi-coat painting delivers the flawless finish you want.

Protect the Finish and Enjoy Your Fresh Look

Now just seal and protect your painted metal cabinets to make the new finish last. Follow these final steps:

• Clean all surfaces again with a lint-free cloth and mild cleaner to remove dust.
• Apply two coats of clear acrylic sealer, allowing full drying time between coats. Sealers add protection and sheen.
• Reinstall all shelves, hardware, and accessories. Take care not to scratch the fresh paint.
• Avoid slamming doors or scrubbing the finish for at least 5-7 days to allow paint to fully cure.
• Touch up any problem spots with leftover paint. Store extra paint to facilitate future repairs.
• Enjoy your updated space! Properly restored cabinets should maintain their freshly painted look for many years.

With some effort and TLC, metal cabinets can be restored to look updated and eye-catching once again. Follow this thorough process from start to finish to achieve stunning results. Just think how great your home will look with revived metal cabinets sprucing up the space!

Frequently Asked Questions About Restoring Metal Cabinets

How do I remove old paint from metal cabinets?
