To: Top Answer There is Roundup for lawns. You would want to water your lawn eventually. Poster wants to know when he can water his lawn because the directions do not state when it is safe. That is why they are asking the question. Answer remains the same though...it is safe after a half hour. I would wait a day myself though just to make sure it gets baked in real good. Then water the heck out of it and get ready to put some good food down on it in a week when it's done killin the weeds.
