- Lint-free cloth
- Rubber gloves
- Masking tape
- 4" bristle brush
- Scotch Brite Pad (Fine) or 320-400 grit sandpaper
- For water-based application: Acrylic primer/acrylic latex-based exterior grade paint. We recommend using "Sherwin Williams PrepRite® Bonding Primer" with compatible acrylic-latex paint for optimal paint adhesion.
Step 1: Surface Preparation
- Lay door horizontally on saw horses or a table.
- Remove all the hardware and mask off anything you don't want painted, such as the glass insert.
- DO NOT SAND GRAINED FIBERGLASS.
- Wipe the door with mineral spirits to clean any dust or residue from the surface. Allow door surface to dry completely before applying stain paint. Do not use hydro-carbon based solvents to clean the surface as such products may leave a residue.
- Apply primer with a 4" brush beginning with the panels. Follow the manufacturer's instructions for drying time before applying topcoat. Continue to apply theprimeto ALL 6 sides. Doors which have been bored and morticed for hardware should be primed inside of the lock bore as well.
- The primer must be completely dry before applying the topcoat.
Step 2: Painting
- Apply exterior grade paint with 4" brush beginning with the panels.
- It is common practice to paint both stiles the same color as the exterior side of the door. If applying a second coat, follow the manufacturer's instructions for drying time between coats.
- Continue to apply the top coat to ALL 6 sides. door which have been bored and morticed for hardware should be finished inside of the lock bore as well.
- When using stains, mineral spirits, paints, or other hazardous materials, always read and follow the manufacturer's instructions. Plastpro, Inc. makes no representations as to the proper use of other manufacturers' products.
- When working with paints or solvents, make sure the working area is well ventilated.
- Keep away from heat and flame as materials may be combustible.
- Paints or solvents may cause skin and eye irritation. Avoid contact with skin and eyes.
- Keep out of reach of children.
Even a well-finished fiberglass door will be affected by exposure and weathering from sun, moisture, and air pollutants. It is considered normal maintenance to re-apply the topcoat approximately every two years.
Due to the variability in finishing materials, application conditions and techniques, all of which are beyond the control of Plastpro . Plastpro cannot be responsible for the performance of field applied finishes or individual application techniques.
