Have used for 3 or 4 years always wondered if it rained shortly after.
Tempo SC Ultra is best applied when rain is not expected within 24 hours of application so it has time to dry and adhere to the surface it is applied to. Rain before would not effect it just be sure the area is not soaked so it makes contact with the surfaces applied to.
