How to Reface a Fireplace With Concrete

Brick fireplaces go in and out of fashion, and many people do not care for them at all. If brick facade is a bit too traditional or bucolic for your tastes, it is not difficult to make over your brick fireplace and give it a look that is a bit more updated. Using concrete mixed with sand, known as stucco, is a convenient and inexpensive way to do this. While stucco may bring to mind images of a rough, Southwestern-style surface, an untextured stucco finish is actually very sleek and modern looking and is something you can accomplish yourself in a weekend.

Instructions

    • 1

      Make sure that your fireplace bricks are clean and dry.

    • 2

      Use a large paintbrush to apply a generous, even coat of concrete bonding agent onto the bricks of your fireplace. Let the bonding agent dry for 30 to 45 minutes.

    • 3

      In a large bucket, use a mixing rod to mix together ready-made stucco (which is a mixture of concrete and clean sand) and enough of the concrete bonding agent to make a toothpaste-like consistency.

      Trowel on a three-eighth-inch thick coat of stucco using a flat metal trowel. Ensure that this coat is even and level. Cover the fireplace edges. Let this coat dry for 30 minutes, until it is soft-set.

    • 5

      With a notched trowel, make straight grooves in the first coat of stucco from one end of the fireplace to the other. This helps the second coat adhere to the first.

    • 6

      Use the straight trowel again to apply a second, thicker coat of stucco that is also level and even in all areas. Again, do not forget the edges. Carefully smooth the surface of the stucco with the trowel.

      Let the refaced fireplace cure completely for two to three days before using it.
