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 provided in a 10 lb. pail only.
- HEAT STOP-50 is provided in a 50 lb. bag only.
- 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 retemper this product as you would with a regular mortar.
