Begin with a medium-grit sandpaper or an electric sander like the Ryobi 18V ONE+ Palm Sander to efficiently remove any peeling or cracked paint. For minor imperfections or dents, fill them with a Earl's White MulTfill Ready To Use Filler and sand the area once it's dry to ensure a level surface. Next, apply Dulux PRECISION White Maximum Strength Adhesion Primer. This primer is specially formulated to bond to a variety of tough-to-paint surfaces that typically resist coatings.
For new green Duracoat doors, start by lightly sanding the door to enhance primer adhesion and create a smooth finish. Use a fine-grit sandpaper and ensure the surface is clean and dust-free before moving on to the next step. Next, apply Zinsser 1L Bulls Eye 1-2-3 Undercoat Primer Sealer Stain Blocker. This primer is excellent for exterior use, providing strong adhesion and blocking stains.
When painting, it’s important to coat both sides and all edges of the door, including the top and bottom. These areas are particularly vulnerable to water penetration, which can lead to swelling or damage over time. Ensure thorough coverage to protect the door from the elements.
Once the primer has dried, proceed with a high-quality water-based exterior paint for your topcoat such as Dulux Aquanamel. Water-based paints are ideal for exterior doors due to their durability and ease of cleanup with just water. Follow the manufacturer's instructions for drying times and the recommended number of coats for the best results.
