Finishing of Parkwood Duramax Fibreglass Doors Choose the right paint If you have a composite fibreglass door, ensure your primer has ‘fibreglass’ included in the suitable surfaces or is an etching primer and select an applicable solvent-based or acrylic enamel designed for exterior exposure for best results. If in doubt, ask the experts – the right paint can mean the difference between a great result and an average one. 1. Remove your door and get it ready You may think that taking your door off the doorframe isn’t necessary, but trust us, it will make the process of painting your door a whole lot easier. Simply remove everything attached to the door such as the doorknob, knocker, hinges etc, remove from the frame and place on a flat, horizontal surface, ready to paint. Give it a gentle sanding before you start if needed and then dust it off thoroughly before you begin. 2. Start with an undercoat Caution Ensure your primer/undercoat has ‘fibreglass’ and PVC included in the suitable surfaces. Dulux Precision Maximum Strength Adhesion Primer or Resene Quick Dry Primer Undercoat or PPG Paints 3 in 1 Prep are recommended. An undercoat helps to seal the door and smooth out any imperfections so don’t skip this step. Give your primer a good stir and then apply to the door, beginning at the edges. Fill a paint tray and, using a roller, apply the paint evenly to the door in a W formation, making sure you’re covered it evenly. Leave it to dry completely before continuing – this may take a few hours. 3. Apply your topcoats Apply two topcoats of applicable solvent based or acrylic enamel designed for exterior exposure of a colour of your choice, sanding lightly between coats. We recommend Resene Lustacryl semigloss waterborne enamel for light colours and Resene Lustacryl CoolColour semi-gloss waterborne enamel for dark colours or PPG Water Based Enamel or Dulux Aquanamel water-based enamel. In coastal areas a 3rd coat is recommended due to harsh salt atmospheric conditions. making sure to do so evenly, watching out for drips, and leave ample time for the first coat to try before applying the second. 4. Dry and replace Once you’re happy with the finish of your door and it’s completely dry, you can replace the hardware you’ve removed and re-attach it to the door frame. Welcome home! Normal Maintenance 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. https://parkwooddoors.co.nz/wp-content/uploads/2025/03/Finishing-of-Parkwood-Duramax-Composite-Doors-2025.pdf
