Add just a little water at a time as you go, working it in with a shovel. To mix concrete, thrust the shovel underneath the premix concrete and fold it over on itself, distributing the wetness. Continue adding small amounts of water as you mix the concrete until all of it looks the same and it achieves a consistency that is neither dry nor soupy.
