Application Information Ambient Air Temperature +5 °C min. / +40 °C max. Relative Air Humidity 20 % min. / 85 % max. Dew Point Beware of condensation. The substrate and uncured applied product must be at least +3 °C above dew point to reduce the risk of condensation or blooming on the surface of the applied product. Metal surfaces will be more prone to temperature fluctuations occurring and wind chill effects. Substrate Temperature +5 °C min. / +60 °C max. Substrate Moisture Content ≤ 4% parts by weight The following test methods can be used to determine the substrate moisture content: Pot Life Note: The material in opened containers must be applied before a surface skin occurs. Note: Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity. ~1–2 hours Applied Product Ready for Use Important: The impact of heavy rain or rain showers can physically mark or damage the membrane in its liquid state. Note: Application at higher than recommended film thicknesses may result in a prolonged “soft” feel to the coating. This will eventually cure and harden. Note: Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity. Ambient conditions | Rain resistant | Touch dry | Full cure | +2°C / 50 % r.h. | ~12 hours | ~20 hours | >24 hours | +10°C / 50 % r.h. | ~9 hours | ~15 hours | ~24 hours | +20°C / 50 % r.h. | ~6 hours | ~10 hours | ~18 hours | +30°C / 50 % r.h. | ~4 hours | ~6 hours | ~14 hours |
