PRODUCT DATA

Developed for installation of firebrick and clay flue lining in masonry fireplace and chimney installations. Heat Stop II is 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.

  • For estimating purposes approximately 50 lbs. will lay up 100 firebricks (2 ½ inch thick) if joint thickness is 1/16 to 1/8 inch as recommended.
  • Joint thickness up to 1/2 inch is acceptable with this product and is quite common.
  • Add clean water (approximately 3/4 to 1 quart) for each 10 lbs. and mix thoroughly. No other additives required.
  • Cold water works best. Warm water quickens set time. Do not remix or re-temper this product as you would with a regular mortar.
