Our home inspector noted some cracking in the mortor in our fireplace. Eric ordered a two pack of this product to fix the issues.
Fireplace vacuumed and cleaned up, then new mortor liberally applied to any areas that looked like they could use it. The next step was to cure it with a fire per manufacturers directions. A cheap and easy way to give our fireplace more lifespan.
A little load of avocado wood that was burned shortly after. Phillip approves 🙂
