Great price, cheap freight, sets rock-solid
Arrived quickly with lower shipping costs than I budgeted for. Found it a little tough to mix evenly, but once in place, it cured hard and set very well. Great value for the price.

Unsatisfied with the refractory
Rigidiser and firebricks were fantastic, the castable refractory was unusable. Unable to form a spreadable consistency, due to the pebbly mixture. Consistency of muddy gravel that would not spread well and would not adhere to the walls of the forge.
