Hold offThu — today & tonight
  • High condensation risk overnight — surface dips to within 0.6°F of the 73°F dew point (low 73°F, 100% cloud, 3 mph wind). A fresh stain can blush/blister. Stop 4h before dew falls.
  • Humidity peaks at 100% — well above the 85% ceiling; cure stalls and moisture gets trapped.
  • Rain likely in the 24h cure window (100% chance, ~90mm) — it can wash out or mar an uncured stain.

Hold off. 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.
