How to Paint FRP Panels? From Prep to Finish (Covered)

Fiberglass Reinforced Polyester panels (FRP) are a composite material often used in construction and other industrial applications. While FRP panels are solid and durable, they can also be challenging to paint, according to many painters.

Because the material is non-porous, meaning that paint will not adhere to it as it would to other surfaces. But don’t worry; it won’t be hard for you.

It is an easy process. With just a little bit of know-how, you can achieve professional-looking results. To achieve a smooth, even finish on FRP panels, following the proper painting techniques is essential. You must use the proper type of paint and primer.

How to Paint FRP Panels? A step-by-step guide

FRP, or fiberglass-reinforced plastic, is a robust and durable material often used in various applications, including boat hulls, showers, and paneling. While it is a rigid material, it can be scratched or gouged if you’re not careful, so it’s essential to take care when handling and installing FRP panels.

Painting an FRP panel is a great way to do it if you want to add a style to your home or office. Here’s a step-by-step guide on how to paint FRP panels:

Step 1: Prepare the surface

Before you start painting, you must ensure the FRP panel’s surface is clean and free of dirt or debris. You can do this by wiping it down with a damp cloth or using a mild cleaner.

Step 2: scour the surface

After drying the surface, you’ll need to use fine-grit sandpaper to lightly scour the surface of the FRP panel. This will help to create a smooth surface for the paint to adhere to.

Step 3: Apply a primer

After you’ve sanded the surface, you’ll need to apply a primer. This will help the paint to adhere to the FRP panel and will also help to create a smooth, even finish. You can use acrylic primer for this purpose.

You’ll need to use a paintbrush or roller to apply the primer. Start by painting a small section at a time and then move on to the next section.

Step 4: paint the panel

Once you’ve applied the primer, you can start painting the FRP panel. You can use any type of paint you like, but we recommend using acrylic paint.

You’ll need to use a paintbrush or roller to paint the panel. Start with a small section and then move on to the next section. Continue until the entire panel is painted.

Step 5: allow the paint to dry

After you finish painting, you’ll need to allow the paint to dry. This usually takes about 24 hours. Once the paint is dry, you can install the FRP panel in its desired location.

What Type of Paint Will Adhere to FRP?

Fiberglass Reinforced Plastic is a material commonly used in various applications, from boats to shower stalls. It is made by combining glass fibers with resin and then curing it with heat. The resulting material is strong and durable, making it an ideal choice for many applications.

One common question about FRP is what type of paint will stick to it. The answer depends on the type of resin used to make the FRP. If the FRP is made with epoxy resin, an epoxy-based paint will adhere to it. If it is made with polyester resin, a polyester-based paint will adhere to it.

Well, not all paints are created equal. Some paints, even if they are the correct type for the FRP, will not adhere well. This is often due to the paint not being designed for plastic use. In these cases, it is best to consult with the paint manufacturer to see if they have a recommended paint for use on FRP.

How Do You Cover Frp Panels?

If you’re looking to cover FRP panels, you’ll need to consider a few things. FRP panels are made of fiberglass-reinforced plastic, making them more delicate than your average panel. You’ll want to make sure you have some sort of padding between the panel and whatever it is you’re covering it with.

Something like bubble wrap or foam would work well. You also need to be careful about what kind of adhesive you use. Some adhesives can damage FRP panels, so it’s essential to read the labels carefully and choose one specifically designed for use with these panels.

Once you have your adhesive, simply apply it around the edge of the panel and then lay your covering material over the top. Apply pressure evenly around the edges to make sure everything sticks appropriately. And that’s all there is to it! With a bit of care, you can easily cover FRP panels without damaging them.

Can You Spray Paint on FRP?

Yes, you can spray paint FRP. However, FRP is not a type of paint but rather a material often used with paint. When spraying paint on fiberglass-reinforced plastic, use a primer specifically designed for this type of material. Also, don’t forget to sand the surface of the FRP before painting it.

Spray painting FRP, or fiberglass-reinforced plastic, is a process that can be done to change the color of the material or to protect it from damage. The type of paint and the amount of prep work required will vary depending on the project.

It’s essential to follow all directions carefully when spraying painting FRP to get the best results.

Can the Same Paint Used for FRP Panels be Used Inside a Deep Freezer?

Yes, special deep freezer paint options are available for FRP panels that are suitable for the extreme temperatures inside a deep freezer. These paints are designed to withstand the freezing temperatures without cracking or peeling, providing a long-lasting and durable finish for the panels.

Is Epoxy Paint suitable for FRP?

When choosing paint for fiberglass reinforced plastic (FRP), epoxy paint is often the best option. This type of paint is designed specifically for use on FRP, and it is very durable and resistant to chemicals and weathering.

Epoxy paint offers several benefits for FRP surfaces:

  • Adhesion: Epoxy paint forms a strong bond with FRP surfaces, ensuring good adhesion and preventing peeling or flaking over time.
  • Durability: Epoxy paint is highly resistant to wear, chemicals, water, and UV exposure. This makes it suitable for applications where FRP surfaces might be exposed to harsh environments or heavy use.
  • Protection: Epoxy paint provides a protective barrier that helps prevent corrosion, degradation, and damage to the FRP substrate.
  • Aesthetics: Epoxy paints are available in a wide range of colors and finishes, allowing you to achieve the desired appearance for your FRP surfaces.

The Amazing Way To Paint on Fiberglass Reinforced Plastic


FRP panels are a great way to add color to any room or space. With a little preparation and the correct type of paint, you can achieve a professional-looking finish that will last for years.

When painting FRP panels, it’s essential to use paint that will adhere well to the surface. Some good options include epoxy paint or acrylic paint. Also, cover the panels with a primer before painting to ensure the paint will adhere properly.

You can also use spray paint as the best option. This will give you a smooth, even finish that will look great. Once the paint is applied, you can add any desired embellishments to the panels. Thank you for reading!
