THINGS YOU WILL NEED:

  • Drill
  • Thin-set mortar
  • 8-10 penny nails
  • Caulk
  • Tiles
  • Handsaw
  • ½ inch cement backer board
  • Tile spacers
  • Grout
  • ¾ plywood
  • Two galvanized backer board screws
  • Tile nippers
  • Damp rag
  • Eye protection
  • Notched trowel

Instructions

  1. Read the user manual to find out specific requirements for sizing.
  2. Put the stove on top of the ½ inch cement backer board. Take measurements of the dimensions of the backer board extending 16 more inches from the stove on all sides. The addition of extra measurements makes sure the furnace is at the center. A more oversized hearth creates space for storing wood and makes it easy to reload the firebox.
  3. Draw the shape of choice on the cement backer board and the plywood. The plywood sits on the floor and thus acts as the backing for the cement backer board. The hearth can be of your desired shape or a shape that matches your needs and specification.
  4. Cut the exact dimensions out of a ¾ inch plywood with a hand saw. For the cement backer board, cut it using a utility knife.
  5. Put the cement backer board on the plywood and join them using 8- 10 Penny nails.
  6. Dry set the tiles at the top of the hearth pad to find the tiles’ design from the front edge. Using a tile cutter, cut the tiles to size.
  7. Apply a 1/8 inch layer of mortar or cement onto the cement board using a trowel. Spread starting at the front part and place the tiles gently, one tile at a time. Create furrows in the cement or mortar using the edge notched edge of the trowel.
  8. Place the tiles gently on the wet mortar or cement, creating your desired pattern. Do this until you remain with tiles that need to be reshaped or resized. Leave adequate room for the grout by using spacers between the tiles.
  9. Put on eye protection to protect your eyes from tile particles. Using tile nippers, cut the tiles that do not fit your design into your desired shape or size.
  10. Apply mortar or cement at the back of these tiles, then gently press the tile into position.
  11. Remove the spacers between the tiles and allow the pad to dry for at least 24 hours for the mortar or cement to set well.
  12. Spread grout to the joints between the tiles with a rubber grout float. Grout the hearth pad at a 45- degree angle. Do not hold your grout tool on the floor or edge tile at this angle.
  13. Remove excess grout with a utility sponge and a spatula. Clean the left grout residue after 30 minutes with a damp rag.
  14. After the grout dries, spread a clear liquid sealer to the grout.
  15. Fill the last joints using Caulk. Ideally, the builder can use a wet finger to smooth the caulk line.
  16. Using a nail, join a 1-by- 3 MDF board as a trim around the hearth pad. Put the hearth pad on plywood and nail it on the plywood using 8 penny nails.
  17. Place your stove on your hearth pad after allowing it to dry for three days.

Note: Use a user manual and local building rules to know specific requirements for its hearth to provide enough thermal protection. If you are using cement, ensure it has a low K factor .this lowers the amount of heat conducted by the hearth pad.

The area of the stove will determine the size of the hearth pad. Always use a heat-resistant material to make a hearth to prevent heat damage on the floor. It is vital to place the hearth pad on a continuous surface. The hearth owner can use a hearth pad for decoration purposes.
