Sold in a pint sized mini paint can.
To use our brick filler, simply mix the powder with water until it makes a paste.
It's best used for shallow cracks and cavities. The filler needs to be fired to set so it's not recommended for the top of kiln lids, but would work for the underneath side. Use this product in conjunction with inswool pumpable refractory caulk for greater adhesion and to fill deeper voids.
Be sure to wear a NIOSH certified respirator when handling refractory powder.
