Spray Paint Fiberglass Garage Door

Take your time and apply thin even coats.
Spray paint fiberglass garage door. Unlike wood fiberglass is nonporous. Use a new roller cover. Your door will look much better if you put on two thin coats of paint as opposed to one thick coat. And to get spray paint to work with a fiberglass garage door requires a certain level of skill.
For homeowners who have fiberglass garage doors the most efficient way to paint them is to use spray paint. Prime the garage door with the brush. Dries faster krylon acrylic latex paints take about 30 to 60 minutes to completely dry up. 100 acrylic paint is one of the best paints you can use for painting your fiberglass doors.
That is not to say that you cannot paint fiberglass but do take the correct precautions and choose a good primer to increase the staying power. However like metal it does require some preparation before you get started. Apply acrylic latex paint to the primed fiberglass garage door using the roller. Fiberglass has a somewhat paint resistant surface which can affect the longevity of the coat you put on it.
Clean the surface of your fiberglass door with dish soap. If there are any recesses you will have more brush work to do. Wait two to three hours for the paint to dry. If the fiberglass door is completely flat you can use a paint brush to cut around the edges and a roller to paint the rest of the door.
Apply the paint as you did the primer.
