How to Refinish an Old Metal Medicine Cabinet

Cleaning the Medicine Cabinet

The first step is to thoroughly clean the inside and outside of the medicine cabinet to remove any dirt, grease or soap scum buildup.

• Remove everything from inside the cabinet and wipe down the shelves with a mild detergent and water. Scrub away any sticky residue or built up grime.
• Spray the exterior of the cabinet with a degreasing cleaner. Allow it to sit for 5-10 minutes before scrubbing away dirt and oils with a damp cloth. Pay close attention to handles and corners where grime tends to collect.
• Rinse the entire cabinet with clean water and dry it completely with a lint-free cloth. This will ensure there is no residue left behind before priming and painting.

Sanding Down the Surface

Once cleaned, you’ll need to scuff up the surface to help the new paint adhere properly.

• Use 220 grit sandpaper to lightly sand the interior and exterior of the cabinet. Try to sand in the direction of the grain to avoid noticeable scratches.
• Focus on areas where the original paint has chipped or peeled away. Feather out the edges to create a smooth transition.
• Spend more time sanding any rust spots until they are removed completely. Rust left under new paint will continue to spread.
• Wipe away all sanding dust with a tack cloth. Make sure the surface is perfectly clean and dry before moving onto priming.

Applying Primer

Primer creates a smooth, uniform surface for the new paint to stick to.

• Look for metal primer or enamel undercoater made specifically for use on metal and galvanized steel. This will ensure maximum adhesion.
• Apply 2-3 thin, even coats of primer allowing proper drying time between coats. Thick coats can cause drips or lead to uneven coverage.
• Be sure to get full coverage, priming the interior, exterior, edges and corners thoroughly. Extend the primer just beyond the edges.
• Sand lightly with 400 grit sandpaper between coats to smooth out any drips or bumps. Wipe clean with a tack cloth when done.

Painting the Medicine Cabinet

Once primed, you can paint the cabinet any color you like.

• Choose a high-quality metal paint or spray paint made for metal surfaces. An enamel, oil-based paint will hold up best.
• Opt for satin, semi-gloss or high-gloss sheens for easy cleaning and a sleek look. Stay away from flat or matte.
• Apply 2-3 thin coats of paint, allowing each coat to fully dry between applications. Thick coats can drip or run.
• Use smooth, even and overlapping strokes while spraying. Maintain a consistent distance from the surface.
• Paint the interior first, then do the exterior for full coverage with no missed or unpainted spots.
• Allow the paint to cure fully, at least 24 hours, before reinstalling the shelves and replacing your items.

With a good clean, sand and fresh coat of durable paint, your outdated metal medicine cabinet will look like new again. The simple steps of proper prep work, priming and painting will help the refinished surface hold up for years to come.

FAQ About Refinishing Metal Medicine Cabinets

To remove rust, first scrub the area with steel wool or sandpaper to get rid of any loose rust flakes. For deeper rust, use a rust-removing chemical solution or a rust converter before priming and painting.

Do I need to take the door off my medicine cabinet when refinishing it?

It’s best to remove the door if possible to allow for easier access when cleaning, sanding and painting. Use painters tape to mask off any hinges or hardware. If removing it isn’t an option, carefully work around the fixed door.
