Akona Medium-Duty Refractory Mortar is a dry, preblended mortar for laying firebrick and masonry in fireplaces, fire pits, pizza ovens, BBQs and chimney work. It is rated to 2,550°F, air-entrained for freeze-thaw resistance, and gives about an hour of working time before it sets. Once cured it becomes water-insoluble and acid-resistant, and it has passed ASTM C199, C1283 and E136 testing. The 25-pound tub suits small jobs and is easier to handle than full bags of castable refractory.
