Repairing Small Holes & Chips in Brick

Click on image to enlarge

  1. Dig out any loose particles with a small knife.
  2. Brush and vacuum the surface of the brick clean to remove any loose material or crumbling firebrick.
  3. Wet the brick surface lightly with clean fresh water. Use a paint brush or spray bottle (make sure there is no soap residue in the bottle).
  4. Apply a thin coat of brick cement all over the hole. This is defined as about 1/32" to 1/16" thick. Do this with your finger, a small brush, or a spatula.
  5. Fill hole with the special grout material. Apply grout with a spatula (like plaster). You can also use your finger. Push it into the hole. It is OK to let it be a rough surface or slightly larger than the hole it is filling.
  6. Let dry for 24 hours.
  7. Take some rough sandpaper and sand surface to even it out with the rest of the firebrick.
  8. Run the First Firing Cycle ( See first-firing.pdf in the Operation Section or see this search link).
  9. You can brush on brick facing afterward if you desire.
