What happens if asphalt sealcoat is applied when the relative humidity is above 85% and rain is expected within 4 hours?

1. The sealcoat cures twice as fast due to increased atmospheric moisture content.
2. The sealcoat converts instantly into a rigid concrete-like structural slab.
3. The emulsion will fail to dry properly and may wash off into storm drains.
4. The sealcoat turns bright yellow and loses all asphalt binding capability.
