Thanks DennisLinkletter, I picked up a used kamado and need to do some repairs. I already have a tub of Acrylic Grout I purchased from Lowe's Home Improvement store and was wondering if I could use it - https://www.lowes.com/pl/flooring-tools-supplies/tile-tools-supplies/grout/acrylic-premix/4294856532-920575991071. I would be just filling tears/cracks with a surface application. Would this work?
