Temps for SA won't matter enough. Do it Saturday in the morning when its still warm, will be midnight before it even gets close to worry.
as noted if it bothers you cover plastic and toss a blanket on it. Our forecast temps are not low enough to make me worry about your project.
I'd not add the weight for a week or more though if possible. Longer is always better IMHO. Couple weeks if you can manage it. It might not need it. In now way can waiting hurt.
We can keep Larry Root and all his idiotic blabber and user names on here, but we can't get Ralph back..... Whiskey Tango Foxtrot, over....
