Let dry thoroughly, then fill in the cracks with Sonolastic NP-1 in silver-gray or limestone color, strictly following manufacturer's instructions. Pick the color that best matches your concrete. Do not substitute for the Sonolastic NP-1 . . . it is a proven, industrial strength product. If the cracks are deeper than 1 inch, tamp in some backer rod so that you have about a 3/4 inch crack depth to caulk. Backer rod is a round hard foam that comes in various diameters and lengths. The backer rod should be a little larger than the cracks are wide. You will probably have to buy several sizes to fit all your cracks. Do not caulk over the top of your concrete, just fill the cracks to the top.
