Directions

  • Rip pine boards

    Start by ripping the pine boards into 2 1/2” boards. (All boards should be 1 1/2” x 2 1/2”)

  • See diagram for cut list.

    Cut each board to length using the framing diagram provided.

  • Drill pocket holes

    Drill all of the pocket holes and assemble the frame per the diagram description.

  • Attach frame to wall

    Attach the frame to the wall. Be sure to attach it directly to studs or use the proper anchors to attach it safely.

  • Wrap frame with cement board

    Begin wrapping the whole frame with cement board. Be sure to install the metal corner bead on the corners after all of the cement board is installed. This will ensure nice, clean lines all around the edge of your fireplace.

  • Skim coat

    Now it’s time to skim coat the fireplace using pre-mixed mortar and a trowel. I did 3 coats total and I let each coat dry at least 12 hours before applying the next.

  • Sand

    Once dry, knock down any super rough patches or blemishes in the mortar using the 120 grit sanding block.

  • Install baseboard

    Use the 1”x6” mdf board to install a baseboard on the bottom of the fireplace using the nail gun and 2” brad nails. Be sure to caulk along the edges.

  • Install top molding

    Use the 1”x2” mdf board to install the molding on the top of the fireplace. Be sure to caulk along the edges again.

  • Finish

    Time to paint & decorate!
