Things You'll Need:
- Lumber
- Bricks
- Mortar
- Concave jointer
-
Step 1
Clean the surface of the floor where you will build the hearth. Remove carpet, tile or linoleum and scrape up glue residue.
-
Step 2
Build a temporary frame for the bricks. When measuring for the frame, remember to allow about 1/2 inch between each brick for mortar. Set the frame where you will build the hearth.
-
Step 3
Lay the bricks inside the frame without mortaring them to make sure they fit and that the pattern you choose fits the room's decor.
-
Step 4
Mix the mortar. Don't mix more than you can use in two hours. If the mortar starts to set, add a little water and remix it.
-
Step 5
Lay a bed of mortar in the bottom of the frame. Set the bricks in the mortar and tap them lightly to set them in place. Leave a gap between the bricks for grout. Use a level to make sure all the bricks are the same height.
-
Step 6
Scrape mortar into the gaps between the bricks and use a dowel, rod or concave jointer to smooth out the seams and remove air pockets. Let the hearth cure for 36 hours before continuing.
-
Step 7
Remove the frame from the bricks. Finish the sides with tile or mosaic for a decorative touch or use molding around the brick.
