Tools and Materials You'll Need 

Make sure you have the following items before you start: 

• Sandpaper (80-, 120-, and 220-grit) 

• Orbital sander (optional, but helpful) 

• Screwdriver 

• Wood filler (for dents or cracks) 

• Putty knife 

• High-quality exterior wood stain or paint 

• Brushes or foam applicators 

• Drop cloth 

• Painter’s tape 

• Clear protective topcoat (polyurethane or spar urethane) 

 

Step-by-Step Door Refinishing Process 

Step 1: Remove the Door 

Start by taking the door off its hinges. This gives you better control and access to all surfaces. 

• Lay it flat on a pair of sawhorses or a sturdy work surface. 

• Remove all hardware including the knob, lock, and any decorative elements. 

Step 2: Strip Old Finish 

If your door has multiple layers of old paint or varnish, use a paint stripper or sand it down. 

• Chemical stripper: Apply and scrape off according to the manufacturer’s instructions. 

• Sanding: Use an orbital sander with 80-grit paper to remove the top layers, then work up to 120- and 220-grit for a smooth surface. 

Step 3: Repair Any Damage 

Inspect the wood for cracks, dents, or gouges. 

• Use wood filler and a putty knife to fill imperfections. 

• Let dry completely, then sand smooth. 

Step 4: Clean the Surface 

Wipe down the entire door with a damp cloth or tack cloth to remove dust and debris. A clean surface is key for proper adhesion. 

Step 5: Apply Stain or Paint 

Choose a high-quality stain or exterior-grade paint: 

• Staining: Apply in the direction of the wood grain using a brush or foam pad. Wipe off excess with a clean rag. 

• Painting: Use long, even strokes with a quality brush to avoid streaks or drips. Let dry completely between coats. 

Apply a second coat if needed for deeper color or coverage. 

Step 6: Seal with a Protective Finish 

Once the stain or paint is dry, apply a clear topcoat to protect your work from weather and UV damage. 

• Use spar urethane for exterior durability. 

• Apply 2–3 coats, sanding lightly with fine grit between coats. 

Step 7: Reinstall the Door 

Once fully dry and cured: 

• Reattach the hardware. 

• Rehang the door and check that it opens and closes smoothly. 

 

Pro Tips for a Professional-Looking Finish 

• Always sand between coats of stain or polyurethane for an ultra-smooth finish. 

• Avoid working in direct sunlight to prevent drying too fast. 

• Choose a stain color that complements your home’s exterior or trim. 

• If your door is metal or fiberglass, use products made specifically for those materials.
