Cold mornings (down to 50°F, floor is 50°F) — wait for the surface to warm past midday before you coat.
- High condensation risk overnight — surface dips to within 1.1°F of the 64°F dew point (low 64°F, 100% cloud, 3 mph wind). A fresh coat can blush/blister. Stop 4h before dew falls.
- Rain likely in the 24h cure window (98% chance, ~9.2mm) — it can wash out or mar an uncured coat.
- 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
Installing within 5°F of the dew point causes amine blush / carbamation — a cloudy, greasy, hazed floor. The slab surface temp, not the air, is what counts.
- • Surface temp must stay 5°F above the dew point through application and cure (ASTM D3276 / ISO 8502-42).
- • Air + surface in the 50–86°F band (low-temp lines to 50°F).
- • Humidity under 85%; ideally under 80%.
- • 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.
