Important limitations
- Local conditions vary. Forecasts may not reflect conditions at your exact job site (sun vs shade, elevation, wind exposure, proximity to water, and microclimates).
- Surface and substrate matter. Surface temperature can differ from air temperature. Substrate moisture, dew, frost, and condensation can make conditions unsafe even if the forecast looks favorable.
- Product-specific requirements override. Always follow the manufacturer’s label for temperature, humidity, curing time, recoat windows, and precipitation exposure. When in doubt, follow the stricter rule.
- Timing assumptions. Recommendations are based on forecast time steps and conservative thresholds. Short-lived changes can occur between forecast hours.
