HEAT STOP 50 & HEAT STOP II
Formulation is similar to each other and developed for installation of firebrick and clay flue lining in masonry fireplace and chimney installations. They are the product of choice for masonry bread ovens, fireplace and chimney installations (interior or exterior) or where moisture may be present in masonry chimney installation.
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.
