Weather and temperature limitations. The curing of bond coat depends upon the weather.
- Bond coat should not be applied unless the air temperature in the shade and the pavement temperature are 10°C (50°F) and rising
- Warm to hot weather is best. Higher temperatures help bond coat material cure faster.

- No rain in 48 hours. Rain can cause material to run into waterways.
