Maybe your fiberglass door came with the house, and it’s never matched your style. Or maybe the finish has faded over time, and now it looks dull or discolored. You might’ve even tried to clean it up with polish or a wood-look gel stain, only to realize it’s not looking any better. Whether the finish is too orange, too shiny, or just plain outdated, a fiberglass door that’s front and center on your home can feel like a daily annoyance.
It’s understandable to want to fix it since replacing a perfectly good door can be expensive and unnecessary. The good news is, yes, you can paint a fiberglass door. And when done properly, it can completely change the way your front entry looks and feels, adding curb appeal and refreshing the whole space.
At Brush & Roll Painting, we’ve been serving homeowners in Omaha since 1996. Over the years, we’ve painted all kinds of doors, from wood to metal to fiberglass. What we’ve learned is that while fiberglass can be painted, it requires a very specific process to make it look great and hold up long-term. A fiberglass door isn’t like wood; it doesn’t absorb paint the same way, so surface prep and product selection make all the difference.
Our goal with this article isn’t to sell you on anything. We’re here to help you make an informed decision, whether you want to DIY or hire a professional painter. We’ll walk you through what works, what doesn’t, and what to expect from a properly done fiberglass door painting project.
By the end of this article, you’ll understand:
You’ll also walk away with helpful tips for choosing colors, knowing when to repaint, and deciding if it’s time to call in a pro.
Yes, you can paint a fiberglass door. In fact, painting is often one of the best ways to update the look of your entry without spending thousands of dollars on a replacement.
Fiberglass is durable and resists dents and warping better than wood or steel, but the original factory finish can start to fade or peel over time, especially if it gets a lot of sun or weather exposure. If your fiberglass door is structurally sound but the color or finish looks off, painting it is a smart option.
That said, there’s a right way and a wrong way to go about it. Fiberglass is non-porous, which means regular paint won’t grip well without some prep. If you skip steps or use the wrong products, the paint may peel or bubble sooner than you'd like.
Here’s what a professional painting process for a fiberglass door looks like, using high-quality materials and proper prep to ensure long-term durability.
Start by either removing the hardware (handle, lock, kickplate, etc.) or carefully taping it off with painter’s tape and plastic. Taking hardware off gives the cleanest look, but taping works too if you’re careful.
For doors with glass panes or inserts, use painter’s tape to mask around the glass so you don’t get paint on it.
Even if the door doesn’t look dirty, it likely has oils, dust, or residue that will keep paint from sticking. We recommend scrubbing it with a degreasing cleaner like TSP (trisodium phosphate) and rinsing with clean water.
Allow the door to fully dry before the next step.
This is one of the most important steps and the one most often skipped in DIY projects. Because fiberglass is smooth and doesn’t absorb paint like wood, it needs to be lightly sanded with 180-220 grit sandpaper to give the surface some grit.
You're not trying to sand it down to bare fiberglass, just dull the existing finish. Wipe the dust off afterward with a tack cloth or damp microfiber.
Not just any primer will do. You need a bonding primer made to stick to slick surfaces like fiberglass. Products like Stix from INSL-X or XIM bonding primer are our favorites.
Apply the primer evenly with a quality brush or roller and let it dry fully according to the label. Some products need 24 hours of cure time before you can topcoat.
For exterior fiberglass doors, you’ll want a high-performance paint designed for doors and trim. We recommend using a urethane-fortified enamel or waterborne alkyd product. These are more durable and provide a smoother, harder finish.
At Brush & Roll Painting, we often use Benjamin Moore Aura for exterior doors because it cures quickly and stands up to daily use, weather, and sun.
Use a high-quality synthetic brush for recessed panels and a microfiber or foam roller for flat areas. The goal is to get a smooth, even finish without brush marks or roller texture.
Apply two coats, allowing proper dry time in between. If you’re working outside, try to paint in the shade and avoid days that are too hot or humid.
Even though paint might feel dry to the touch after a few hours, it takes time to fully cure. Avoid touching, cleaning, or reinstalling hardware too soon. Give it a full 24-48 hours before reattaching hardware or closing the door tightly.
Painting your fiberglass door gives you the chance to make a statement or coordinate with other elements of your home.
Here are some popular color ideas Omaha homeowners often go with:
Whatever color you choose, be sure it complements your home’s siding, trim, and roofing.
Painting a fiberglass door can be a weekend project, but it requires the right prep, tools, and patience. If you’re handy and enjoy taking on home projects, it’s doable, but expect to spend a good amount of time on each step.
Here are a few reasons Omaha homeowners sometimes choose to hire a professional instead:
A professional painter will typically charge between $300 and $600 for a front door depending on condition, size, and complexity. That includes sanding, priming, and applying two coats of premium paint.
These mistakes can lead to peeling, bubbling, or an uneven finish that will need to be redone far sooner than expected.
Even a properly painted door may need a refresh over time. Keep an eye out for:
High-quality paints, when applied correctly, can last 5–10 years before needing repainting.
If your fiberglass door doesn’t match your home or feels outdated, painting it is a smart way to give your entry a whole new look without replacing the entire door. When done right, with the right prep, bonding primer, and durable paint, you can get a beautiful, long-lasting finish that boosts curb appeal and makes coming home feel better every day.
