Cold mornings (down to 40°F, floor is 50°F) — wait for the surface to warm past midday before you paint.
- High condensation risk overnight — surface dips to within 1.8°F of the 56°F dew point (low 58°F, 82% cloud, 4 mph wind). A fresh paint can blush/blister. Stop 4h before dew falls.
- High humidity (94%, over the 85% mark) slows drying — keep an eye on the cure window.
Hold off. These are forecast numbers — confirm the surface temperature on-site before you start.
Why these thresholds
Overnight dew condensing on a fresh coat causes blistering, surfactant leaching and peeling — the cause of 40%+ of exterior paint failures.
- • Surface temp must stay 5°F above the dew point through application and cure (ASTM D3276 / ISO 8502-42).
- • Air + surface in the 50–85°F band (low-temp lines to 35°F).
- • Humidity under 85%; ideally under 70%.
- • No rain for 24h after application.
- • We use the forecast ground-surface temperature as a surface-temp proxy — confirm on-site with an IR thermometer.
