  • Setting Oven Floor - Fire Clay not available

    Sorry I might be entering the wrong conversation, but could someone give me some advice on this?

    So i have vermiculite insulation in place (about 5 inches) and now I need to set the oven floor. I do not have fire clay available in my area so i cant do the fire clay and sand mixture.

    But i do have refractory mortar. Can i use that instead or is there something better i should use?

    Just use dry sand.
    Any kind of mortar is not recommended, you want the bricks to be able to move.

      Thanks for the response! Do you happen to know how much i should add on top? in terms of thickness?

        As little as you can get away with, it's only to level your floor bricks, I probably averaged about 10mm.
        I used pumice dust, only because it was a by product of me crushing the pumice, I was going to use sand,
        I used a notched tiling trowel and tapped the bricks with a rubber hammer, if one was too low I just put a bit more dust under it, too high and I scraped a bit out.
