How long before you can water after an application of 4-Speed XT?
What is the safe time before pets can use the yard?
Do not apply 4-Speed XT if rainfall is expected within 4 hours and avoid irrigation for 24 hours following the application. Children and pets should not be present during the application and may return after the treated surfaces are completely dried.
