Unfortunately, the answer is no. Beautiful as fiberglass doors might seem, they are quite troublesome when it comes to painting. They have a unique texture that resembles real wood, making them look very cool, but these doors are also tricky to deal with. If you choose the wrong kind of paint, your fiberglass door might end up in a disaster. 

Without further ado, let’s check out this review and buying guide for useful information. 

Buying Guide

Before purchasing any products, it would be useful to do some research about them. With that said, we are going to give you some detailed guidelines to help you.

Types Of Paint For Fiberglass Door

Like any other paints, fiberglass paints come in various degrees of shine or gloss. These include high gloss, regular gloss, and flat finishes. Because fiberglass doors have frequent exposure to water and sunlight, it is necessary to protect them from those external factors with a proper kind of paint. In this case, exterior paints will be the perfect choice. 

Generally, there are three main types of fiberglass door paints. 

  • Acrylic Paint: For fiberglass doors, the IMO, 100% acrylic paint is undoubtedly the perfect option. Usually, Acrylic paint is ideal with a semi-gloss or satin finish.

But before you decide to purchase one, contact the manufacturer for useful information. Ask them whether it is water-based or not. By doing this, you’ll get the most eye-pleasing look for your fiberglass door, as well as avoid making your door look dull. 

  • Alkyd Paint: This particular paint contains oil. Like the Acrylic paint, this one is ideal for fiberglass doors. However, the only downside of this product is that it has a very long dry time.

It is advisable to leave the door open to dry out when you finish painting. However, the sunlight can be harmful, so beware. 

For a better coating, you should remember to clean the paint surface regularly and ensure its dryness. 

  • Gel Stain: These products are perfect for exterior garage fiberglass doors. However, it requires clear varnish after painting. It is quite easy to apply this paint – all you need is a rag or a brush.

Application

Like other materials, fiberglass doors require a primer beforehand. It is crucial to choose a primer that is compatible with the paint you use. 

Generally, most fiberglass paints are workable with urethane, epoxy, and latex primers. However, we do advise against etching primers. These can not work well with fiberglass paints. Never forget to check the product’s description for recommended topcoat paints, too.

It is not good to buy primers from one company and opt for paints from another manufacturer. Instead, you should purchase both in the same company if possible. By doing this, you can get the optimal results.

Also, it is vital to maintain consistency between the fiberglass resin and paint. Specifically, if your door is an epoxy resin fiberglass one, it would be best to opt for an epoxy-based paint. For polyester-resin fiberglass doors, a polyester-based paint is a right option.

FAQs

Q1: What Kind Of Paint Do You Use On A Fiberglass Door?

A: Aside from the paints we’ve recommended, you can try acrylic, epoxy-based or polyester-based paint. As mentioned before, epoxy resin paint is specifically designed for epoxy resin fiberglass doors. Similarly, polyester resin paint is exclusive for polyester resin counterparts. 

Q2: Do You Have To Sand A Fiberglass Door Before Painting?

A: Not recommended. Since fiberglass doors usually have smooth surfaces, you can still have an enjoyable and smooth experience painting. Also, if you sand it too hard, your fiberglass door might end up losing its texture.

However, we do advise you to do some preparation before painting. It is perfectly fine to sand the wooden trim around glass insets. The ideal sandpaper to do this job is the 220-grit one. Then, get rid of sanding dust with a lint-free cloth that is dipped in acetone beforehand.

Q3: How Do You Paint A Textured Fiberglass Door?

A: For this type of fiberglass door, it is quite a challenging task. You should be extra careful and gentle when painting textured fiberglass doors

First and foremost, open the paint can and stir it. This step requires some patience to succeed. It would be best if you stirred the paint slowly to get the paint evenly mixed.

Under no circumstances should you stir the paint rapidly. Otherwise, there may appear some unwanted air bubbles on the paint surface. 

Next, dip the brush into the paint and paint accordingly. First comes the wooden trim around glass inserts, followed by the wood’s grain.

Q4: Is It Better To Paint Or Stain A Fiberglass Door?

A: It depends.

For those who want to have a solid flat finish on their front doors, the ideal method is to paint. Because most fiberglass doors have smooth exterior designs, a painted finish is undoubtedly a wise choice. 

It is widely believed that painted fiberglass doors offer more durability than their stained counterparts. More often than not, this assumption is valid. 

However, it is not always the case. Many factors can significantly affect the durability of a fiberglass door’s finished surface. For example, the materials used, how well the painter does the job, the elements it gets exposed to, and the owner’s care.

Also, the amount and the intensity of sunlight play a big part in affecting the door’s finish. Therefore, it is virtually impossible to claim whether painting is better than staining and vice versa.

Q5: Can You Paint Over Stained Fiberglass Doors?

A: Yes, but only if you use an exterior Acrylic paint.

Acrylic paints have more excellent resistance to sunlight than other competitors. Only when you have already primed the surface could you apply exterior acrylic paint over a stained fiberglass door.

In this case, apply no less than two coats of exterior acrylic primer with a roller. It is advisable to use a natural-bristle brush.
