How To Refinish A Fiberglass Door: 4 Easy Steps

A fiberglass door is a popular option for many homeowners due to its durability and low maintenance. However, after years of exposure to the elements, a fiberglass door may start to look worn or dull.

If you’re looking to spruce up your fiberglass door, refinishing it is an easy and affordable way to give it new life. Here’s how you can refinish a fiberglass door in just four steps.

Why do You need To Refinish A Fiberglass Door?

Refinishing a fiberglass door is an important project to consider if you want to protect and enhance the surface of your entryway. Not only does it help to keep dirt and debris from collecting on the door, but it also adds an extra layer of protection from inclement weather.

In addition, many finishes for fiberglass doors come in a variety of styles, colors, and levels of gloss. This gives you more freedom when designing the entrance of your home.

By refinishing your fiberglass door, you can enjoy an attractive look for years to come without worrying about its lasting durability.

Refinishing A Fiberglass Door

Step 1: Gather Your Supplies

Before you begin the refinishing process, it’s important that you have all the materials you need on hand. You’ll need a power sander, sandpaper (100-120 grit), painter’s tape, drop cloths, paintbrush or roller (depending on the size of surface area), exterior primer and paint, and mineral spirits/turpentine.

Make sure that all your supplies are in good condition before beginning this project.

Step 2: Prep the Surface

Once your supplies are gathered together, open your doors and windows for ventilation purposes and lay down dropcloth(s). Next, use the power sander with 100-120 grit sandpaper to remove any loose material from the surface of your door.

Once this is complete, use painter’s tape to cover any areas of your door that should not be painted (i.e., window frames or hardware). This will ensure that these areas remain untouched during the painting process.

Step 3: Prime & Paint

Once the surface has been prepped for painting, it’s time to apply primer. For best results apply two coats of exterior grade primer with an outdoor-rated paint brush or roller making sure each coat has had ample time to dry between applications (approximately 2 hours).

After priming is complete apply two coats of exterior grade paint allowing each coat ample time to dry between applications as well (again approximately 2 hours).

Wait at least 24 hours before closing/using your newly refinished fiberglass door(s) so that they can fully cure.

Priming vs Staining

Refinishing a fiberglass door can be a daunting task, but once you understand the steps involved it becomes far less intimidating. An important part of the refinishing process involves priming and staining the surface of your door.

Priming refers to the application of a specialized coating that creates an ideal surface for subsequent layers of paint or stain to be added. Staining, on the other hand, is a chemical process that alters the color, shade, and texture of the material being treated.

Essentially it imbues your fiberglass door with an organic look without having to use actual wood grains or colors.

So before you start tackling any fiberglass project, make sure you have understood what both priming and staining involve in order to achieve optimum results.

Step 4: Clean Up & Admire Your Work

After the final coat of paint is dry it’s time for clean up! Dispose of used sandpaper properly then wipe down surfaces with mineral spirits/turpentine if necessary. Then step back and admire your beautiful new fiberglass doors!

Do you need to strip the fiberglass door before restaining?

Stripping the fiberglass door before restaining is recommended as it helps to prevent the staining from looking uneven. Stripping removes any existing dirt, grime, and old finishes that may be present. Without stripping, these elements can affect the color of your new stain.

To strip a fiberglass door, start by sanding lightly with 120-grit sandpaper to create a smooth surface. Then apply a chemical stripper evenly over the entire surface and wait 10 minutes for it to break down the old finish.

Once completed, wipe away all of the chemical stripper residues with a damp cloth and let them dry completely before you start staining.

How To Strip A Fiberglass Door?

Stripping a fiberglass door can seem intimidating at first, but if done correctly it is relatively straightforward. Keep in mind there will be a few fumes from the stripping process, so make sure to do the job in an open space or with adequate ventilation.

First, remove any hardware and use a heat gun to soften any paint or varnish. Once softened, use a scraper and steel wool to begin lifting earlier layers of finish.

Lastly, you’ll want to hand-sand the entire surface with 220-grit sandpaper prior to painting. Taking your time during each step of the process is paramount for getting that perfect stripper job on your fiberglass door!
