Concrete crack sealants and caulks are the most commonly used product to fill cracks in concrete. They come in squeeze tubes and can be applied directly into the crack with a caulking gun. Both do a good job of keeping out water and insects. Concrete surfaces cannot be repaired with concrete.
Instead, use a concrete repair mix; they are available at home centers and online. Options include epoxy composites, latex patch material, and mortar mixes. The latter option works best for filling large cracks (or chipped edges), while the other products are suitable for cracks in concrete inch wide or narrower. Epoxy or latex fillers should be used in any crack 1/8 inch wide or smaller.
Start by mixing the epoxy product. It comes in two separate parts that require thorough mixing for the concrete patch to work. Once mixed, the solution can be applied to the crack with a spatula or mason's trowel. According to my tests, Sikaflex self-leveling sealant is the best concrete crack filler you can buy right now.
