How to Strip Paint from Metal Cabinets

Stripping old paint and restoring metal cabinets to their original glory can seem like an intimidating task, but with the right tools, materials, and techniques, it is very achievable as a DIY project. Properly preparing and stripping the old paint will allow you to repaint, refinish, or restore your metal cabinets to get them looking like new again.

Necessary Supplies for Stripping Paint from Metal Cabinets

Before starting your paint stripping project, make sure you have gathered all the necessary supplies:

• Paint stripper: Look for a stripper formulated for use on metal, such as a methylene chloride-based stripper. This is the active ingredient that works to soften and lift the paint.
• Plastic spreaders or scrapers: You’ll need these for applying the stripper and scraping off the softened paint. Opt for wooden skewers, plastic putty knives, or specialty scrapers made for paint removal.
• Steel wool: Grades 00 or 000 work best to help scrub off stripped paint residue.
• Sandpaper: Coarse grit sandpaper (60-100 grit) will help smooth and prep the surface after stripping. You may also need finer grit (120-220) for final smoothing before painting.
• Paintbrushes: Disposable bristle brushes are useful for applying stripper to intricate areas.
• Spray bottle or pump sprayer: This helps wet the surface with stripper. Avoid squirt bottles that can’t achieve a fine mist.
• Paint thinner: Used to clean brushes and dissolve any remaining paint stripper residue. Mineral spirits also work well.
• Dry rags & paper towels: You’ll need plenty of these for wiping up excess stripper and paint residue.
• Drop cloths: Protect surrounding surfaces from paint stripper and paint drips.
• Nitrile gloves: Essential for protecting your hands from harsh chemicals.
• Safety goggles & mask: Important PPE for avoiding contact with toxic fumes and chemicals.
• Plastic bags: To properly dispose of paint debris and messy rags.

With the right supplies gathered, you can move on to preparing your cabinets for paint stripping.

Preparing Metal Cabinets for Paint Removal

Before stripping away old paint, take some time to properly prepare your cabinets to make the process easier and minimize damage:

• Remove cabinet doors, drawers, and hardware: Taking cabinet components off makes them easier to work on and stops metal hardware from being damaged by chemicals. Place hardware in a plastic bag for safekeeping.
• Clean cabinet surfaces: Use TSP cleaner and scrub with a plastic bristle brush and rinse to remove grease and grime that could interfere with paint stripper effectiveness.
• Fill any holes & dents: Use wood filler epoxy on nail holes, dents, or other imperfections so they don’t absorb stripper and become enlarged. Allow filler to dry completely.
• Sand glossy surfaces: Scuff sand shiny or glossy paint with 120-150 grit sandpaper so stripper can penetrate better. Watch for lead paint – take proper precautions if sanding.
• Vacuum cabinet interior: Use a soft brush attachment to clean out old paint flakes and dust inside cabinet box.
• Mask off areas: Use painter’s tape and plastic to protect countertops, floors, walls, and any areas you don’t want to strip. This also keeps stripper contained.

Proper prep saves time and headaches once the stripping process begins. Always work in a well-ventilated area and use necessary PPE like gloves and goggles. Now you’re ready to start applying paint stripper.

How to Apply Paint Stripper to Metal Cabinets

Paint stripping chemicals are very powerful, so take care when applying them to your cabinets:

• Read manufacturer instructions: Follow all guidelines for application, re-application times, dwell times, and proper use. Don’t let stripper dry on the surface.
• Protect yourself: Wear nitrile gloves, safety goggles, and a mask when handling and applying chemicals. Work in a well-ventilated area.
• Stir stripper before use: Mixing helps activate the ingredients and makes application easier. Close container immediately after to prevent evaporation.
• Apply a thick coat: Use a plastic spreader, brush, or spray bottle to apply a generously thick layer that covers all painted surfaces completely.
• Let stripper dwell: Allow stripper to penetrate and bubble paint layers, but don’t let it dry completely. Follow manufacturer suggested dwell times.
• Re-apply as needed: Add another coat to any areas that aren’t fully softened. Multiple coats may be needed for many old paint layers.
• Mist with water: Once paint starts loosening, lightly mist stripped areas with water. This helps further soften paint so it’s easier to remove.

Take your time applying stripper thoroughly and allowing proper dwell time for best results. Next, it’s time to start removing all that loosened paint.

How to Remove Softened Paint from Metal Cabinets

Once stripper has done its work bubbles and loosening paint, the next step is to carefully scrape and scrub it all away:

• Use plastic or wood scrapers: Carefully scrape in direction of wood grain to lift softened paint away in strips or sheets. Avoid using metal scrapers or wire brushes.
• Try a plastic bristle brush: Use short, back & forth motions to help scrub paint residue off the surface that scrapers may leave behind.
• Switch to steel wool: 00 or 000 grade works well to lightly scrub and lift remaining bits of paint out of crevices, carvings, and details.
• Rinse repeatedly: Wipe surface frequently with clean rags and rinse with mineral spirits followed by water to keep removing paint residue. Change rags often.
• Work slowly & carefully: Taking your time helps avoid damaging the underlying surface. Use lighter pressure on delicate or intricate areas.
• Get into corners: Use toothpicks, skewers, or small brushes to meticulously scrape paint out of inside corners and crevices.
• Remove all residue: Keep working until you reveal the bare wood or metal underneath. Test an area with new stripper to reveal any paint you may have missed.

Thoroughly stripping all loosened paint residue is crucial. Any leftover paint will make it difficult for new paint to properly adhere in the future.

How to Neutralize and Clean Surfaces After Paint Stripping

Once all the paint is successfully removed, there are a few more important steps:

• Follow manufacturer neutralizing guidelines: Most strippers require wiping surface with mineral spirits followed by water to remove residue.
• Use baking soda + water: Make a thick paste and gently scrub to neutralize any remaining stripper and prevent future reactions with new paint.
• Rinse thoroughly: Wipe the entire surface with clean water several times to remove all residue. Dry surfaces completely with clean rags.
• Sand lightly: Use 120-150 grit sandpaper to smooth any uneven areas and lightly etch the surface for better paint adhesion.
• Vacuum again: Use brush attachment to thoroughly remove all dust before re-assembly and painting.
• Dispose of materials safely: Place used stripper rags, brushes, and contaminated PPE in sealed plastic bags before throwing away.

Proper cleanup and disposal helps ensure every trace of stripper is removed so your cabinets accept new paint well. After all that hard work stripping, you want the new paint job to last.

Tips for Repainting Metal Cabinets After Stripping

Once your metal cabinets are stripped bare and cleaned, follow these tips for the repainting process:

• Choose the right metal primer: Opt for one formulated especially for metal, such as Rustoleum or Krylon metal primers, to ensure best adhesion.
• Consider a conversion coating: Using a phosphoric acid solution helps etch and prep the metal for long-lasting results.
• Apply primer thinly: Only one thin, even coat of metal primer is needed. Too much can cause the new paint to peel later on.
• Lightly sand again: Smooth any drips or uneven primer with 220 grit sandpaper before painting.
• Carefully inspect: Check for any remaining paint residue and strip again if needed so new paint sticks well.
• Finish with quality metal paint: Use an enamel, acrylic, or urethane paint recommended for metal cabinets. Add multiple thin coats allowing proper dry time between coats.
• Replace hardware: Screw cabinet hardware back into place carefully to avoid scratching your fresh paint job.

With proper prep and painting techniques, your restored metal cabinets should now look fresh, renewed, and ready to enjoy for years to come!
