I'm building a wood fence with metal posts this weekend. How long do I need to let the cement cure for?
Depends entirely on what cement product you use. Some set up VERY quickly. Some take longer. If you use the quick stuff you should be good to go in a couple of hours. This is for a wood fence... If you were doing chain link where you had to stretch the fence pulling on the posts I would say let it set over night.
maybe a 2 days or more, depends of the wheather conditions and check the directions on the back of the bag.
Can buy Post Crete , drill in max of 2 hrs , Most builders merchants and diy stores sell it . Good luck
Depends on the cement you use. If it's a quick set kind, it will say on the bag (probably a coupla-few hours tops). If it's just regular Portland cement, wait a day or two (or whatever it says on the bag).
Cement the posts today; attach the rails and pickets tomorrow.
