How to Prepare Wooden Doors for Painting

Start by removing the door from its hinges and placing it horizontally on a stable surface. This position allows even application and prevents paint drips. Take off all handles, locks, hinges, and other hardware — masking them will never give as clean a result as full removal.

Clean the surface with a mild detergent or wood cleaner to eliminate grease, fingerprints, and dust that could affect adhesion. Once the door is completely dry, check for cracks, dents, or peeling paint. Use wood filler or putty to repair any imperfections, applying it with a putty knife in thin layers for a seamless look. Let the filler dry, then sand the surface with medium-grit sandpaper to remove old paint and smooth out repaired areas. Follow with fine-grit sandpaper to create an even texture for the primer.

Always sand in the direction of the wood grain to avoid scratches. After sanding, remove dust with a tack cloth or a slightly damp microfiber cloth. Applying a high-quality wood primer is crucial — it seals the surface, prevents stains, and ensures the paint adheres evenly. Choose a primer compatible with your chosen paint type (latex or oil-based) and let it dry completely according to manufacturer instructions. For exterior doors, opt for a weather-resistant primer that protects against moisture and UV damage.

When the primer is dry, lightly sand once more with fine-grit paper for the smoothest base possible. Wipe away any remaining dust before applying the first coat of paint. Following these steps helps you achieve an even, vibrant, and lasting finish.
