Prepare the Garage Door

Proper preparation is crucial for a long-lasting finish. Start by cleaning the garage door thoroughly to remove dirt, grease, and old paint. Use a mild detergent mixed with water for the best results.

Sanding and Repairing

Once the door is clean, inspect it for any cracks or imperfections. Use sandpaper to smooth rough areas and fill any gaps with a suitable filler. This step ensures that the paint adheres well and provides a uniform appearance.

Apply Primer

Applying a primer is essential, especially if you're painting over a dark color or metal surface. Choose a primer that matches your garage door material, whether wood, metal, or fiberglass. Use a roller for large areas and a brush for edges and corners.

Allow the primer to dry completely, following the manufacturer's instructions for the best results.

Start Painting

Once the primer is dry, it's time to apply the paint. Opt for a high-quality exterior paint designed to withstand New Zealand's weather conditions. Use a roller for broad strokes and a brush for detailed areas and edges.

Painting Technique

Begin at the top of the door and work your way down. Apply the paint in thin, even layers to prevent drips and ensure a smooth finish. Allow each coat to dry thoroughly before applying the next one. Two coats are generally sufficient for a durable finish.
