Here, I’ll discuss the best paints to use on fiberglass doors and provide some tips for getting a durable finish. So if you’re looking to give your fiberglass door a fresh coat of paint, keep reading!

What Kind of Paint is Best to Use on Fiberglass Door

Why Are Fiberglass Doors Different?

Fiberglass doors are made from a composite material that is strong and durable but also porous. This means that regular paints may not adhere well to the surface, leading to peeling and chipping over time.

It’s important to choose a paint that is specifically designed for use on fiberglass, as it will have the necessary adhesives and resins to bond with the surface. Regular paints may not have these adhesives, which can cause them to peel or chip off easily.

When selecting paint for a fiberglass door, be sure to read the label and look for keywords such as “adhesive,” “bonding,” or “fiberglass.” These indicate that the paint has been specifically formulated to stick to fiberglass surfaces.

Different Types Of Paint Options for Fiberglass Doors

Fiberglass doors offer a durable and attractive option for both residential and commercial applications. However, they require special types of paint to ensure that the door is properly protected from the elements and retains its aesthetic appeal. To help you get the best results from your fiberglass door, here is a look at the different types of paint to use on fiberglass doors.

Acrylic latex paint

This is a good choice for fiberglass doors, as it is flexible and resistant to peeling and chipping. It is also easy to clean and has low levels of volatile organic compounds (VOCs), making it more environmentally friendly. This paint dries to a smooth finish and is available in a wide range of colors.

Epoxy paint

Another good option for fiberglass doors is epoxy paint, which has excellent adhesion and durability. It is more difficult to work with than acrylic latex paint because it dries faster and requires more precision. It is a two-part paint that must be mixed before application and dries to a hard, glossy finish.

Urethane paint

Urethane paint is a high-quality option that is very durable and resistant to chipping and fading. It is more expensive than other types of paint and may require the use of special thinners, but it can provide a long-lasting finish. It dries to a glossy finish and is resistant to water and UV light.

When selecting a paint for your fiberglass door, consider the level of durability and protection that you need. If the door is in a high-traffic area or exposed to the elements, a more durable paint such as Epoxy or urethane may be a good choice. If you’re just looking to give the door a fresh coat of color, acrylic latex paint may be sufficient.

Can the Paint Used for Fiberglass Doors be Used for Painting a Rusty Metal Roof?

Yes, the paint used for fiberglass doors can also be used for painting a rusty metal roof. With the right preparation and application, the paint can effectively adhere to the metal surface and provide long-lasting protection against the elements. It’s important to choose a high-quality paint specifically designed for painting a rusty metal roof to ensure optimal results.

Is the Paint for Fiberglass Doors Similar to the Paint for Asphalt and Tarmac?

When painting asphalt surfaces, it’s important to use the right type of paint. For fiberglass doors, you’ll need a different paint compared to what is used for asphalt and tarmac. The paint for fiberglass doors is specifically designed for the material and won’t adhere well to asphalt surfaces.

How Can You Ensure Quality Fiberglass Door Painting?

When it comes to painting fiberglass doors, it can be a tricky job if you are not familiar with the process. Fortunately, the following tips can help ensure that the job is done correctly and that the door looks amazing when it is finished.

Clean The Door Thoroughly

Before you start painting, make sure to clean the door thoroughly with soap and water to remove any dirt or grime. You may also want to use a de-glosser to remove any gloss from the surface. This will help the paint adhere better and give you a smoother finish.

Sand The Door

Sanding the door with fine-grit sandpaper can help rough up the surface and improve adhesion. Be sure to sand in the same direction as the grain to avoid creating scratches.

Use A Primer

Applying a primer before the paint can help improve adhesion and give the paint a better base to stick to. Primer can also help hide any imperfections in the door and create a more even finish.

Follow The Manufacturer’s Instructions

Make sure to follow the instructions on the paint can, including how many coats to apply and how long to wait between coats. This will help ensure that the paint goes on smoothly and dries properly.

The Advantages of Painting a Fiberglass Door

Painting a fiberglass door can be a great way to boost the aesthetic of your home. Not only does it provide a fresh look, but there are also several advantages to painting a fiberglass door. Here are just a few of the advantages of painting a fiberglass door:


One of the biggest advantages of painting a fiberglass door is its durability. Fiberglass is a strong material, and when it is properly painted, it can last for many years without fading or chipping. The finish is also resistant to cracking, peeling, and damage from the elements. This makes it a great choice for those looking for an attractive and long-lasting door.

Low Maintenance

Another advantage of painting a fiberglass door is that it requires very little maintenance. Unlike wood, fiberglass does not need to be refinished or stained every few years. It is also easy to clean and does not require any special treatments.


Painting a fiberglass door is a cost-effective option for many homeowners. It is usually much cheaper than replacing the door with a new one and can be completed in just a few hours. This makes it a great choice for those on a budget.

Energy Efficiency

Your home’s energy efficiency can also be increased by painting fiberglass doors. A painted fiberglass door adds an additional layer of insulation, keeping your house warmer and cooler in the winter and summer, respectively. This can lower your energy costs, making it a long-term wise investment.


Selecting the right paint for your fiberglass door is crucial to getting a good finish and ensuring that the paint lasts. Acrylic latex, Epoxy, and urethane paints are all good choices for fiberglass, depending on your needs.

By following these tips and paying attention to the manufacturer’s instructions, you can give your fiberglass door a fresh coat of paint that will look great and last for years to come.
