How long before rain does Tempo SC Ultra have to be applied to still be effective?
We sprayed yesterday and it rained a few hours later. How long does it have to be before it rains for the spraying to be most effective?
Tempo SC Ultra needs to have at least 4 hours to dry properly before the rain happens. This product holds up very well in the rain. If it rained before the product had enough time to dry, it is possible that it may not be as effective.
