Is It Cheaper to Paint an Exterior Door or Buy a New One?
Painting usually wins on cost, but sometimes replacement makes more sense. This breaks down real numbers, time involved, durability differences, and when it’s smarter to just buy new versus refreshing what you have.
Exterior doors face sun, rain, freezing, and thawing all year. Interior paint cracks and peels fast outside. You need 100 percent acrylic latex or oil-based exterior enamel that stays flexible and blocks UV. Skip this and you’ll be repainting every couple of years.
Painting usually wins on cost if the door is structurally sound. A full prep and quality exterior enamel can last five to ten years or more. Replace only if the door is badly warped, rotted, or the core is failing. Painting saves hundreds compared with buying new.
Remove hardware, wash thoroughly, sand to remove loose paint and gloss, apply exterior primer that blocks tannin, then two or three thin coats of exterior enamel. Paint both sides if possible and pay extra attention to the bottom edge. Work in shade on a dry day with good temperatures.
Clean off all oxidation and dirt, scuff the surface lightly, use a rust-inhibiting bonding primer made for metal, then apply exterior-grade enamel in thin coats. Thick coats or skipping primer are the usual culprits for peeling.
No. Hot sun makes paint skin over too fast, causing wrinkles, bubbles, and poor adhesion. Paint in shade on a mild day, ideally between 50 and 85 degrees with low humidity. Check the forecast first.
Not required but it saves time on large flat areas or when doing the whole entry. Good airless or HVLP sprayers give even coverage. Brush and roller still work fine for smaller jobs and better control around hardware and edges.
