Powder coating is a popular finish for metal surfaces, such as furniture, doors, and railings. It provides a durable and attractive finish that can last for years. But over time, the powder coat can become scratched, faded, or just plain worn out. When that happens, you can easily restore the finish by painting over powder coat.
What Is Powder Coating?
Powder coating is a type of coating that is applied in a fine powder form and then cured in a heated oven. The powder is made up of a resin and pigment, which, when heated, form a hard, protective finish. Powder coating is an incredibly durable finish, and it is often used to protect surfaces from corrosion, UV damage, and other environmental elements.
What You Will Need
Before you get started, you’ll need to gather the supplies you’ll need for the job. Here’s what you’ll need:
- Paint stripper
- Sandpaper
- Chemical degreaser
- Painter's tape
- Paint brush or roller
- High-temperature paint
Steps to Paint Over Powder Coat
Now that you have all your supplies ready, it’s time to start the job. Here’s what you need to do:
Step 1: Remove the Powder Coat
The first step is to remove the existing powder coat. You can do this with paint stripper, which is a chemical solution that will dissolve the powder coat. As you apply the stripper, you’ll want to use a brush or roller to ensure even coverage. Once the powder coat is dissolved, you’ll need to use sandpaper to remove any remaining residue.
Step 2: Clean the Surface
Next, you’ll need to clean the surface. To do this, you’ll want to use a chemical degreaser. This will help to remove any dirt, grease, or other contaminants that may have built up over time. Make sure to wear gloves and a respirator when working with chemical degreaser.
Step 3: Mask Off Any Surrounding Areas
Once the surface is clean, you’ll want to use painter’s tape to mask off any surrounding areas. This will help to ensure that the new paint doesn’t get onto any other surfaces.
Step 4: Apply the Paint
Now it’s time to apply the paint. You’ll want to use a high-temperature paint, as this will ensure that the paint won’t crack or peel over time. You can use either a paint brush or roller to apply the paint. Make sure to apply the paint in even coats, and allow each coat to dry before applying the next.
Step 5: Allow the Paint to Cure
Once you have applied the paint, you’ll want to allow it to cure. This may take up to 24 hours, depending on the type of paint you are using. Once the paint has cured, you can enjoy your newly painted powder coat!
