There are some products as well that can be purchased that will perform the job of this slurry mix. Generally these mixes are designed to set fast for joining surfaces and fixing active leaks. There are concrete mix additives that can cure in 30 seconds or even underwater to patch a leak. Many times dealing with these products you will find yourself distracted for a moment only to find your trowel firmly embedded in the solidified bucket of mixed concrete moments later. The home made slurry mix described above is much more forgiving than these commercial products and produces reliable results just the same.

Concrete curing times

Concrete takes almost a full month to reach maximum strength. All too often with beginners the anticipation gets the better of you and you end up destroying or damaging your creation by moving or working the concrete too soon after sculpting. I recommend waiting a minimum of 3 full days to begin working the concrete and a full 14 days before attempting to lift or move. Be sure to keep the concrete moist with water at least 2-3 times per day for the initial 3 days.

Now that you have a better understanding of how to make concrete that is great for sculpting artificial rocks, we can take a look at how you are going to sculpt it to look exactly like real stone.
