We have been fixing kilns for years now and have never found a soft brick repair patch that really worked the way we wanted it to. So we formulated our own! Our soft brick filler comes dry so you only have to use what you really need. We have included soft brick powder into the mortar compound to match not only the color of your kiln brick but so the patch also has similar refractory qualities as your current brick. We use this patch in the field when repairing kilns and love it.
Sold in a pint sized mini paint can.
To use our brick filler, simply mix the powder with water until it makes a paste.
Be sure to wear a NIOSH certified respirator when handling refractory powder.
