The best concrete for a fireplace includes a mix of high alumina cement and refractory aggregates like crushed brick, limestone, or slag. This special concrete mixture can withstand the high heat of a fireplace without losing strength or durability.

Cover an outdated brick fireplace with contemporary tile. Once you’ve exposed the raw masonry, mix up a batch of thinset concrete and spread it over the surface of the brick using a broad, flat hand trowel. Allow the concrete to dry for at least 24 hours, then apply a second coat of latex-infused thinset.
