This AW Perkins Castable Refractory cement comes in a handy 50 lb. Tub, and is up to the job of sealing your masonry to masonry joints. This castable refractory cement must be heat cured, after which it can withstand 2,000 degree temperatures, and cures to a buff color. Refractory cement is created to be used with masonry joints under 1/4 in. thick, and is a ready mixed mortar that can be used for setting, coating, or resurfacing fire brick, but is to be exclusively as the mortar between fire bricks when building fire boxes.

Please Note: 12.5 lb. tub shown.

Timothy A. from Dacula, GA asked:
I am making molds for a kiln i have designed. Do I have to account for any shrinkage of the material once dried. So if my insulation brick is to be 20 x 20 x 2.25, do I need to make it bigger so it is the proper size when dried? If so how much is recomm

Yes there will be shrinkage. The manufacture does not offer any recommendation as what you are doing has never been preformed by them.

Chuck from MO asked:
Could I use this product to use as an oven bottom? Will it cure at 1-1/2 inch thick?
Could I use this product to use as an oven bottom? Will it cure at 1-1/2 inch thick?
This material is indeed able to be used for this exact purpose. The manufacturer recommends casting any shape thicker than 1 1/4 inches in two stages. For your application, pour a layer approximately 3/4 of an inch thick and allow it to partially set. While the first layer is still soft, pour the second layer. This will ensure that the first layer will have adequate exposure time to oxygen, allowing it to begin the reaction needed to set properly.
