A freshly painted front door is the highest-impact curb appeal improvement per dollar spent. A quality exterior door paint job lasts 5-7 years and can be completed in an afternoon.

Safety First
- •Work in temperatures between 50°F and 90°F. Avoid painting in direct hot sun — the surface dries too quickly and causes brush marks.
- •Do not paint if rain is expected within 24 hours.
Step-by-Step Instructions
Choose the Right Paint
Use exterior-grade paint specifically labeled for doors and trim. It's formulated for UV resistance, temperature extremes, and the repeated handling a door endures. Oil-based paints produce a harder, glossier finish but take longer to dry. Water-based (latex) exterior paints are easier to apply and clean up, and modern formulas are very durable. Choose satin or semi-gloss sheen.
Remove Hardware
Remove the door knocker, house numbers, kick plate, and if possible, the lockset handle. If you can remove the door from its hinges and paint it flat on sawhorses, do so — painting a door flat eliminates drips entirely and is much easier. Slide screws into a piece of cardboard so you don't lose them.
Painting flat on sawhorses produces dramatically better results than painting in the frame. The extra effort of removing the door is worth it for a professional finish.
Clean the Door Surface
Mix TSP substitute per directions and scrub the entire door surface to remove dirt, grease, mildew, chalking paint, and anything else that would prevent adhesion. Rinse thoroughly with clean water and allow to dry completely — at least 2 hours in warm weather, longer in humid conditions. This step determines how well your new paint adheres.
Sand the Surface
Sand the entire door starting with 80-grit to remove flaking or loose paint, progressing to 120-grit to smooth rough areas, then finishing with 220-grit for a final smooth surface. Sand with the grain of the wood. Remove all sanding dust with a tack cloth. Fill any dings, holes, or gouges with exterior wood filler, let dry, and sand smooth.
Prime if Needed
Spot-prime any bare wood areas or sections where old paint was sanded through. If you're making a dramatic color change (dark to light), prime the entire door. Use an exterior oil-based primer for wood doors — it provides superior adhesion and stain blocking over water-based primers.
Paint Panels First
Start with any recessed or raised panels, working paint into corners and edges with the brush. Smooth out brush marks with light strokes along the grain direction. A common mistake is overloading the brush — work with smaller amounts and build up.
Watch for paint runs and drips in panel corners and edges. Catch them immediately by brushing them out with a dry brush. Dried runs are very visible and require re-sanding to fix.
Paint Rails, Stiles, and Edges
After panels, paint horizontal rails, then vertical stiles (the door's structural frame), following the wood grain. Use the foam roller on flat stile and rail surfaces for a smooth, brush-mark-free finish, then follow immediately with the brush to eliminate roller texture. Paint all four edges of the door (top, bottom, and sides) to fully seal it from moisture intrusion.
Second Coat and Curing
Allow the first coat to dry per label directions (typically 2-4 hours). Lightly sand with 220-grit if needed, wipe clean, and apply a second coat. Reinstall hardware only after the paint has cured — wait at least 24 hours before rehinging and operating the door. Full paint cure takes 7 days for maximum hardness.
Apply a thin bead of exterior caulk between the door frame and the wall if there are visible gaps. It improves weatherproofing and dramatically improves the overall appearance.
