The fireback in our stoves is subject to erossion during long term burns.
The material is soft and will break easily.
The cost of a new set of firebacks is not cheap but there is a easy cheap fix.
"FURNACE Cement" This stuff is available at many hardware stores and comes on pints or quarts
To repair a erroded fireback, remove and clean with a soft brush to remove the ash.
Lightly sand the erroded area with coarse sand paper.
Using a putty knife, spread the furnace cement over the erroded area starting in the areas that are the deepest.
It helps to mask the area off with masking tape to keep the repair looking neat.
Lay the fireback flat to do the job.
Apply a small amount and let harden, then another coat and bring the areas up so the original depth is restored. You can use a suitable tool and make the grooves in the surface if you desire.
The fire cement isd rated for the high temps in furnaces and refractories.
A small can of this stuff sells for less than $5.
I have repaired several firebacks this way and the fix works well.
It is black in color so the natural color is not the same but the idea is to protect the back wall of the firebox.
Just a little tidbit
