Expect a one-in-a-million work of art! Concrete is a natural material, and its final cured state can not always be predetermined. If you want a perfectly manicured countertop that looks exactly like the one at the home store, then a concrete countertop may not be for you. If you are looking for a unique countertop with character markings or colorings that reflect the skill of the master craftsman who installed it, however, then a concrete countertop is for you!
