Fiberglass doors and sidelights can be smooth or textured with a wood-grain finish. This material usually does not need to be primed, but painting is required. Premium steel doors are factory-primed and should be painted but not stained.
For new fiberglass doors, you also need to prime them. Priming helps you cut down the extra coating for your fiberglass doors. When you prime before painting your door, the paint coating will last longer. Primers seal the original material of the door and fill the porous surfaces for a smooth paint area.
Any latex based paint will work on fiberglass. If you are painting the exterior side of a door, I recommend exterior paint as it's designed to hold up against weather, but you can certainly use it on the interior side as well.
Primer for bottom paint is not necessary. However, if you use Tuff Stuff marine epoxy primer on the bare fiberglass, it will provide protection against blisters and any moisture. It will also improve adhesion to the hull. Tuff Stuff marine epoxy primer will last for many years.
Acrylic Latex
Acrylic paint adheres well to fiberglass, overcoming one of the main challenges to painting this material. Acrylic paint is less likely to crack and blister, and will hold up well to cleaning. This water-based paint is easy to apply, and contains fewer chemicals, so is more environmentally friendly.
Rust-Oleum Oil-Based Door Paint is designed to bring great color retention and durable protection for your exterior and interior doors. Ideal for metal, wood and fiberglass doors.
Before painting, clean the door with a degreasing cleaner. Fill holes and repair imperfections with sandable filler or spackle. Use 120-grit sandpaper to gently sand the door for a smoother surface that will absorb primer or paint more easily. After sanding, remove dust from the area before priming or painting.
Painting a fiberglass entry door is much like painting a wood door, without a need for sanding before paint is applied. Rinse the door by wiping it down with a damp sponge, then allow the door to dry completely.
Fibreglass can be tough to paint over as it needs to be suitably prepared and primed for topcoats to properly adhere and stick to the surface. Zinsser's Bulls Eye 1-2-3 is ideal for priming fibreglass as it provides a perfect key for topcoats.
Use high-quality acrylic latex house paint (use interior grade on inside surfaces; and exterior grade on the outside surfaces following manufacturer's application instructions.
Pre-primed doors, also known as primed doors, are a great choice if you want to paint your door yourself. Pre-primed doors arrive with a base coat of primer, onto which you can apply a layer or two of paint.
Although you may have painted your primed door to make it look nice and pretty, you still need to spray the paint. The primer will provide an smooth surface for the wood on the permeable surface of it. As a result, special paint must be applied if something wears out, changes temperature, causes water to spray, etc.
1) Yes they require undercoating. The doors are primed, but require a coat of under coat and at least one coat of top coat i.e. enamel etc. Usually the edge of the doors are not primed, so it will need priming anyway.
You should not use oil-based or melamine paints when choosing fiberglass paint; instead, acrylic (100%), polyurethane, polyester, and epoxy paints should be used. It is recommended not to mix primer and paint from different companies, according to many manufacturers and painters.
Kohltech recommends you use a high quality, UV stabilized, clear exterior polyurethane coating (satin or low gloss) used for exterior fiberglass applications. It is important that you apply sealant once a year to ensure maximum protection.
Just as essential as your paint type and color is its finish. Satin or semi-gloss are both good choices for a steel front door, since in addition to having a nice sheen they won't show nicks or scratches as easily as a flat or eggshell finish.
It is an airtight sealer that protects the primer before the walls are ready for paint. It also acts as a binding ingredient between the concrete, and the topcoat of the paint. Epoxy primer paint protects the walls from extreme weather conditions.
A fiberglass-friendly paint can be matte, neutral, or gloss.

Its advanced chemistry provides a sound anchor for topcoats while reducing or potentially eliminating the need for sanding dense, glossy surfaces including Kynar®, PVC, vinyl, Formica®, glass, tile, glazed brick, chalky paints, glossy finishes, fiberglass and metals.
Use acrylic, polyester, polyurethane, or epoxy resin paint on your fiberglass door. Try to pick a paint that matches the type of fiberglass for the best results. Do not use oil-based paints because these can damage the door. Fiberglass-friendly paints are often available in matte, neutral, and gloss finishes.
