How to Paint a Fiberglass Door

Painting a fiberglass door can be a tedious task, especially if it's already varnished. However, there is a method to paint over a varnished fiberglass door without making a mess. The key is to clean, dull, and dry the surface. This general rule applies to painting any glossy surface: paint will not adhere to varnish, so preparation is crucial to avoid future repairs. Use a high-quality bonding primer to ensure paint adhesion, followed by a premium paint for a professional finish. Here’s a step-by-step guide:

Materials Needed:
- Screwdriver or drill
- Wedge
- Drop cloth
- Sawhorses
- Degreaser
- Dish soap
- Warm water
- 220-grit sandpaper
- Tack cloth
- Paint thinner
- Fiberglass filler
- Sanding block
- Painter’s tape
- 6-inch foam roller
- Angled paintbrush
- Bonding primer
- Quality paint

Steps:

1. Remove Hardware:
Use a screwdriver or drill to remove the door handle. Remove the screws holding the door to the hinges, but leave the screws attaching the hinges to the door frame. Slide a wedge under the door edge for support and remove the door from the frame.

2. Set Up Workspace:
Lay a drop cloth on the floor. Set up two sawhorses and place the door on them, ensuring even weight distribution.

3. Clean the Door:
Remove any decals or tape from the door. Use a degreaser to eliminate any sticky residue. Prepare a bucket of soapy water with dish soap and clean the door with a cloth soaked in the solution. Rinse with clean, warm water and let the door dry completely.

4. Sand the Surface:
Sand the door’s surface and edges with 220-grit sandpaper. Use a tack cloth to remove all sanding dust. Wipe the door with a clean cloth dipped in paint thinner to remove any remaining residue.

5. Fill Imperfections:
Fill any dents or holes in the door with a fiberglass filler. Let the filler dry completely. Sand the filler smooth with a sanding block and clean up the dust with a tack cloth. Use painter’s tape to mask off weather stripping and any glass areas.

6. Prime the Door:
Apply a coat of bonding primer with a 6-inch foam roller. Use an angled paintbrush to reach corners and small areas of paneled doors. Allow the primer to dry according to the manufacturer’s instructions. Apply a second coat of primer and let it dry.

7. Paint the Door:
Using a clean 6-inch foam roller, apply a thin coat of quality paint to the door. Avoid applying too much paint at once. Allow the paint to dry as per the manufacturer’s instructions. Apply a second coat of paint and let it dry for 24 hours before reattaching the hardware and reinstalling the door on the hinges.
