Read on to get a detailed guide on how you can seamlessly remove paint from your precious metal door.

Why Strip Paint From Metal Door?

Paint is known to embellish your metal doors, but it tends to create a strong bond with the substrate, just like with any other surface. The strong bond between the paint and the metal door is what makes paint removal a little difficult.

There are many reasons why you may want to strip paint from a metal door which include:

  • Change the look of the door: You may decide to remove paint from your metal door so that you can add a shade that matches other house items.
  • A painting accident: When you accidentally get paint on your door while painting another item, you’ll want to remove it without doubt.
  • For protection: For example, you may want to use weather-resistant paint with outdoor doors, thus creating the need to remove the existing one if it doesn’t serve the purpose.

Regardless of why you may want to do it, here’s a detailed step-by-step guide that can come in handy.

Steps to Strip Paint From Metal Door

1. Prepare Your Working Area

Preparing your working area is the first and most crucial step while embarking on this task. And your line of preparations depends on how you choose to work on your door; will you remove it from the hinges or leave it on?

Remember, most metal doors are heavy, and removing them will require assistance; therefore, the best bet is working on them as they are!

Preparations here involve decluttering the area around the door. Ensure you remove any delicate items that could be damaged during the process. Additionally, keep kids and pets away from the working space.

And to avoid messy cleanups after the paint removal process, consider placing drop cloths on the floor or ground around your working area. If you want to be a little economical, you can opt for old newspapers or recycled cardboard boxes.

The drop cloth or whichever material you choose to cover the area below your door collects any dirt, chemicals, and paints, making the whole process less messy.

2. Wear Your Protective Gear

As much as you cover the floor or ground below your door, be sure to protect yourself too.

For your safety, you can wear long-sleeved shirts and pants (to cover your entire body) and closed shoes (to protect your feet). You also need safety glasses or goggles (to protect your eyes) and a respirator or facemask (to reduce inhalation of toxic fumes from harsh chemicals found in some paint removers).

If possible, it’s advisable to work in a well-ventilated area.

3. Apply the Right Paint Remover

The next step is to apply your paint remover or paint stripper of choice. The paint remover you choose depends on the type of paint on your metal door, whether oil-based, acrylic, latex or water-based.

Remember, different paint strippers are designed for different types of paint. Therefore, getting one meant for the paint in question can go a long way in making the removal process easier. The paint remover should also be designed for use on metals; therefore, ensure you read the packaging carefully.

To apply your paint thinner or stripper, pour the chemical solution in a bowl, depending on the amount of paint you want to strip. Then use a disposable brush to apply the solution to your metal door while carefully following the manufacturer’s instructions.

4. Allow the Paint Remover to Settle

Once you have the paint remover on every corner of your door where there’s paint, leave it to settle and perform its magic.

You can let it be for at least an hour, depending on how cured or stubborn the paint seems. As the stripper or remover starts working, you’ll see the paint begin to bubble up, pulling away from the metal.

The paint stripper weakens the bond between paint and metal, causing it to peel off without damaging the metal substrate, which is what you want, right?

5. Scrape the Paint

If you see the paint bubbling, it’s time to scrape it off. Here you can use a paint scraper to chip off the bubbled paint from the whole flat surface of your door. Also, use scrubbing pads for the curved edges, hinge area, and other hard-to-reach areas (depending on the design of your door).

After chipping away all the bubbled paint, gauge the efficiency of the outcome. If you aren’t satisfied, don’t lose hope. This procedure calls for a little patience. So, just reapply the stripper or remover, wait for it to perform its magic, and then scrape the paint off again.

Continue this process until you strip most of the paint.

6. Apply Mineral Spirits

While most paint strippers and removers will effectively get rid of paint from your metal door, they may miss a spot or two.

These remaining stubborn spots are what call for mineral spirits. This chemical compound is effective in attracting stubborn leftover paint from your door.

Pour the mineral spirits in a bowl and then apply them over every spot on your door where there are stubborn stains. You may use a towel for increased efficiency and reduce wastage by pouring the mineral spirits over your entire door.

If you don’t have mineral spirits, you can use white vinegar, which also works wonders for stubborn paint stains.

After the mineral spirit or white vinegar has worked on the stubborn spots, scrape the paint off and repeat the process until you’re satisfied with the outcome.

7. Clean the Door

Once all the paint, including the few stubborn stains, is cleared, the next step is to wash your door thoroughly. However, before cleaning your door, consider the type of metal used because some metals react to harsh cleaning products.

If yours is a stainless steel door, you can opt for stainless steel cleansers. On the other hand, if it’s an aluminum door, you can use an aluminum cleaner or just the standard soap and water.

For chrome doors, any regular household cleaning product will do. However, if you aren’t sure of the type of metal your door is made of, stick to water and a mild cleaning detergent.

Avoid using strong cleaning chemicals because they can easily corrode your valuable door.

After cleaning, leave your door to dry before working on it. If you had removed it from its original position, it’s now time to screw it back. And if you’re leaving your metal door outdoors, consider applying a layer of weatherproof sealant to keep it free from rust and other weather-related damages.

Tools Needed

Here’s a list of essential items you should have before embarking on this task:

  • Drop cloths
  • Disposable paint brushes
  • Paint remover/ paint striping gel
  • Paint scraper
  • Mineral spirits
  • Water
  • Scrubbing pads
  • Eye protection
  • Hand gloves/rubber gloves
  • Respirator mask/ nose mask

Important Things to Note When Removing Paint From a Metal Door

  • Steer clear of hard-bristled brushes or coarse sandpapers when stripping paint from your valuable metal door because they may damage the underlying metal substrate.
  • Ensure you protect the areas around the door, such as the floor, with drop cloths or other protective materials to reduce damages by paint and chemicals and reduce messy cleanups.
  • Ensure you get a paint stripper designed for use on metals. It should also be suitable for the specific type of paint in question, be it oil-based or water-based.
  • Read all the manufacturer’s instructions carefully before using any chemical solutions.
  • Always wear protective gear and, if possible, work in a well-ventilated area.
  • Avoid cleaning your metal door using harsh cleaning products that may corrode it.
  • If you intend to leave your door paintless before working on it again, consider applying a thin layer of weather-resistant sealant to reduce damages caused by rust and other weather-related problems.
