High condensation risk overnight — surface dips to within 1.8°F of the 74°F dew point (low 76°F, 58% cloud, 7 mph wind). A fresh stain can blush/blister. Stop 4h before dew falls.
- Hot afternoon (94°F, ceiling 90°F) — stain early and follow the shade.
Caution. These are forecast numbers — confirm the surface temperature on-site before you start.
Why these thresholds
Stain applied to a damp or dew-wet board can't penetrate — it beads, stays tacky and flakes. Wood must be dry and stay above the dew point while it sets.
- • Surface temp must stay 5°F above the dew point through application and cure (ASTM D3276 / ISO 8502-42).
- • Air + surface in the 50–90°F band (low-temp lines to 45°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.
