Refractory Cement

These dry-mix refractory mortars are made from high temperature cements and carefully selected aggregates that will not expand or tear the mortar apart when heated. Once dried, these products are non-water soluble and more acid resistant than any other type of product used in these applications. Heat Stop II is available in a one gallon pail. Heat Stop 50 is provided in a 50-lb bag that yields approximately 60 lbs. of refractory mortar.
