Castable Refractory Cement - 12.5 lb

Can't find replacement firebrick for your pre-fabricated zero clearance fireplace? Make your own. Build a form, mix the castable refractory cement, pour into the form and let set up. It's easy and inexpensive.

Originally developed for use in blast furnaces, the castable refractory cement has exceptional strength and abrasion resistance. Ideal for casting into custom shapes to replace worn out or broken firebrick. When the material is mixed with water, it chemically sets and dries brick hard. Can be cast in irregular shapes or as a solid stone bed. 12 1/2 lbs. Casts a block 12" x 12" x 1 1/4".
