Antiquing Fiberglass Doors With Paints

Remove the fiberglass door from the doorway, and move it to your work surface. Remove the door's hinges, knobs and other hardware, and cover what cannot be removed with overlapping strips of painter’s tape.

Dampen a rag with mild soap and water. Use the soapy rag to clean both sides of the door well. Rinse the rag under water until the water runs clear, and use it to wipe the soap residue from the door. Let the door dry completely.

Remove all weather-stripping that you can to take off. This is the perfect time to replace old or worn-out weather-stripping, but leave the stripping off for now.

Apply two coats of latex primer to the door, letting the first application dry completely before applying the second layer. Keep the primer as even as you can over both sides of the door.

Paint the door with two coats of your chosen acrylic paint base color. Let the paint dry 12 to 24 hours.

Mix equal parts water, brown acrylic paint and clear acrylic glaze in a plastic bucket using a paint stick. Dip a paintbrush into the mixture, and apply several long, even strokes of the mixture thinly to the door. Overlap the strokes as little as possible.

Dab over the glaze with a bunched rag to remove most of the glaze. If you want a darker finish, the paint glaze onto the same area again and remove most of it in the same manner. Repeat this all over the door so that the antique finish is even.

Wait for the door to dry 24 hours, and then rehang it. Wait seven to 10 days before installing new weather-stripping.

Repeat the procedure for each fiberglass door you want to have an antique appearance.
