    How To Build Your Own Brick Fireplace

  1. 1

    Mark the dimensions of the fireplace against the wall and the footprint of the fireplace on the floor, using painter's tape.

  2. 2

    Cut the metal lath with a utility knife to fit inside the painter's tape, so the dimensions of the fireplace are covered both against the wall and on the floor. Remove the painter's tape.

  3. 3

    Nail the metal lath into the wall and floor using common or drywall nails.

  4. 4

    Mix the mortar according to the package directions, as each brand of mortar differs.

  5. 5

    Apply a layer of mortar (1/2 to 1 inch thick) with a trowel to each brick before you lay it. Build a base layer, so the footprint of the fireplace is covered, laying bricks about 1/2 to 1 inch apart. Use your hand to smooth the mortar between the bricks if necessary.

  6. 6

    Continue mortaring and laying bricks in layers, so that you are slowly building upward. Continue building until the fireplace is built to the dimensions you desire. Fireplaces are generally 2 to 4 feet high, depending on their aesthetic relation to the height of the ceiling.

  7. 7

    Wipe away excess mortar.

  8. 8

    If the metal lath is visible in any spot on the edges of the fireplace, cover with a layer of grout. Allow the fireplace to dry completely, about 48 to 72 hours, depending on the brand, before lighting a fire.
