How to Stop Paint from Peeling Off Plastic Bumper?

We have all seen paint peeling off a plastic bumper. Whether the paint is just starting to get loose, or all of the paint has come loose and is hanging down, it’s a bad situation. The paint will begin to chip as soon as you begin driving around.

Initially, this small issue may not seem quite a big deal, but if you don’t take proper measures soon, it could result in a huge repair bill.

But how to stop paint from peeling off plastic bumper? In this guide, we will point out different reasons for this problem and how to solve it.

What Causes Paint to Peel on a Bumper?

When paint begins to peel on a bumper, it is usually the result of one of three things: poor adhesion, poor quality paint, or environmental factors.

Poor Adhesion

One of the most common reasons for the paint to peel on a bumper is poor adhesion. This can be caused by several things, including improper surface preparation, using the wrong type of primer, or applying the paint in humid or dusty conditions.

Poor Quality Paint

Another common reason for the paint to peel on a bumper is poor quality paint. This can be the result of using cheap paint, not allowing the paint to properly cure, or using paint that is not designed for use on a bumper.

Environmental Factors

Finally, environmental factors can also cause paint to peel on a bumper. This is most often seen in areas with high humidity or extreme temperatures, as these can cause the paint to expand and contract, leading to cracks and peeling. Also, UV rays can break down the protective barrier of your paint, causing it to fade and eventually peel away.

How to Stop Paint from Peeling Off Plastic Bumper?

One very common issue with plastic bumpers is that the paint tends to peel off. Most car paint problems, including peeling, can be traced to improper preparation or painting techniques. When your painting starts to peel, it’s usually because the paint didn’t adhere properly to the metal surface.

To prevent your car’s paint from peeling, it’s important to regularly wash and wax the exterior. Avoid harsh chemicals on the surface of your car while washing, as these can strip away the protective layer of wax. This can lead to premature fading and peeling.

If your car was recently painted and the paint is already peeling, likely, the body shop didn’t follow proper procedure when they prepped and painted your car.

If you are determined to take this matter into your own hand and do the painting by yourself, follow our instructions for a better painting job.

Now, let’s get into the job. Wear your protective goggles and mask to save your skin and eyes from paint fumes. They can be pretty irritating. So, take these necessary precautions before starting. Also, take your work in a ventilated area.

• First, use a sanding block or sandpaper to sand the surface of the bumper.
• Clean the desired surface. Use soapy water.
• Also, you can use denatured alcohol to remove any dust or debris.
• Next, apply a primer specifically designed for plastic surfaces using a paint brush. It helps the paint to cling and help it last longer.
• Let it completely dry before painting with your desired color of paint.
• As the primer is dry now, it is time to start painting.
• Choose a color that closely matches the original and apply it in thin coats until you’ve got full coverage.
• Use a spray can or spray gun to ensure an even coat of paint and avoid any drips.
• Allow the paint to completely dry.
• To safeguard the paintwork, apply a clear coat.
• Let the clear coat dry at least for 6 hours before driving your car.

Once you are done painting the bumper and ready to drive around, try to keep the bumper out of direct sunlight as much as possible. Also, try to avoid extra cold weather conditions. Doing these will help the paint stick with the bumper for a long time and not peel off.

What Paint Do You Use on Plastic Bumpers?

When it comes to painting plastic, it is important what paint you should use. Some paints will not stick to plastic, while others will adhere just fine. Acrylic paint works great for painting plastic. It’s available in both spray and brush-on varieties, and it adheres well to most types of plastic.

Another option is enamel paint, which also works well on plastic. It’s more durable than acrylic paint once it dries, so it’s a good choice for outdoor projects or items that will see a lot of wear and tear.

You can use a urethane-based paint, specifically a two-part urethane. A two-part urethane will give you the best durable finish that will resist fading and chipping. No matter what kind of paint you choose, make sure they are going to work for plastic surfaces.
