Temperature plays a big role in how well exterior paint sticks and dries. Once winter arrives, the window for safe painting narrows significantly.
General Temperature Guidelines
Most exterior paints need daytime temperatures above 35–50°F to dry and bond correctly. Even if the air warms up for a few hours, the surface you’re painting may still be too cold.
What Cold Weather Does to Paint
- Thickens the paint
- Slows drying
- Makes moisture more likely
- Increases the risk of peeling later
Why Surface Temperature Matters
Shady areas, north-facing walls, and metal surfaces can stay cold long after the air warms up. If the surface stays too cold or damp, the paint will not stick the way it’s supposed to.
When Professionals Paint in Winter
A professional may take on certain exterior projects in winter, but only under the right conditions. If the weather doesn’t meet the paint’s requirements, a good contractor will recommend waiting until temperatures are steady and safe.
