Hard refractory provides armor against both heat, flame and mechanical damage being poked and scraped by work going in and out. Kast-O-Lite 30 works well in around a 1/2" layer but some folks like 1/4",  others folks like more.

Approximate mixing is 1.2 gallons per 55 pounds or 2.79 ounces per pound.

From Frosty

The best cure method according to the maker is to treat it just like hydraulic concrete. It water SETS, it does NOT DRY. These are two entirely different things. Read up on working, and curing a patio or shop floor. Portland cement, concrete and Kastolite set and cure very closely to the same in time and steps. Kastolite refers to concrete procedures as THE way to cure Kastolite for maximum strength and temperature rating. 

Except for water % details the comparison is across the boards close enough to the same as to be interchangeable. 

So, when it sets close it up in a 100% humidity atmosphere for up to 7 days. We do NOT need a max strength cure, we aren't subjecting it to the kinds of forces temps and atmospheric changes a commercial forging or scrap furnace does.

This is not refractory cement.  It is refractory insulation.  Manufacturer does not list IR reradiation characteristics, but it is lighter colored than Rutlands (which shouldn't be used as a forge lining in any case) so will likely reflect more IR.  Material is also 56% alumina, which is also a good indicator IMHO.  Data sheet appended.

Welcome aboard KingCrowleyInc., glad to have you. If you put your general location in the header you might discover how many members live within visiting distance and a LOT of info is location specific. Do you have a preferred form of address we can use? Your logon is pretty cumbersome and if we have to make something up, you'll be stuck with it.:P

Furnace cements and mortars are NOT USEFUL FLAME FACE FURNACE LINERS. They are formulated to bond masonry together and are very short lived in contact with flame. Propane especially is VERY chemically aggressive and more so as a 3,000 f. flame. 

We're not harshing on you but terms can be critical. This instance is as significant as the difference between gasoline and diesel when you fill your vehicle. Using mortar or cements as forge liners is an urban myth almost as utterly wrong as the one about using plaster of Paris and sand, that last can be dangerously BAD. 

We're doing our muddling best to help get a uniform terminology in use around the world.

Frosty The Lucky.
