Hello, my name is Mark Blocker. In this segment we're going to cover how long concrete should cure before setting anchor bolts. That question's going to depend on where you're located and what type of cement you use. Depending on your environment, the ambient temperature of the area, the humidity, what type of cement you're using, that question's going to vary. But generally speaking, concrete will cure in three to seven days. And you're pretty safe to be able to set your anchor bolts after three days. For anchor bolts what they are is they mount in the cement and gives you a way to bolt down let's say the walls of a building on a garage or a home or something of that nature or just allow you to anchor anything to that cement. And what they consist of is a nut, the actual shaft, they're actually studs and a washer. And to mount them in the cement you'll need a rotor hammer and concrete drill bit to drill the holes and how many and where they're located depends on what you're fastening to the slab and what the local building code is. You'll need to check all those. But for most all cases you should be able to set your anchor bolts after three days curing time.
