Repairing Small Holes & Chips in Brick
- Dig out any loose particles with a small knife.
- Brush and vacuum the surface of the brick clean to remove any loose material or crumbling firebrick.
- 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).
- 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.
- 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.
- Let dry for 24 hours.
- Take some rough sandpaper and sand surface to even it out with the rest of the firebrick.
- Run the First Firing Cycle ( See first-firing.pdf in the Operation Section or see this search link).
- You can brush on brick facing afterward if you desire.
