The 50-lb. bag yields about 60 lbs. of refractory mortar after mixing. You will need approximately 50 lbs. of product to lay up 100 firebrick (2 1/2 thick bricks), assuming a joint thickness of 1/16 to 1/8, which is recommended. Joint thickness up to 1/2 is acceptable. Add 3/4 to one quart of cold water for each 10 lbs. of product you use. 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. Safety data sheets are available on request. Always follow manufacturer's instructions. Wear goggles, gloves and a mask. Remember, shipping is FREE for all orders (contiguous US only). Available as a single bag, 4 bags, 6 bags, 12 bags or a full pallet of 48 bags.
