refractory cement / mortar formula ?

[boblee]

Hi there would anybody have a recipe or formula for refractory cement or refractory mortar or fireclay motar or cement that they would like to share .
I see some of the Rutland stuff at our local hardware store but am wondering if its any good. I used a ready to use cement on my first Tempcast core but some of the joints came apart I'm not really impressed with that stuff . I've seen some boiler reliners using some sort of refractory cement in their boiler repair of fire bricks and the stuff seemed very tough , its been there several years and it hasn't cracked yet. I have know idea what its called . It was a dry mix in a bag.
Would anybody have any idea what it might be or know where to get it ?
Thanks Bob

The Rutland is very good stuff, I suspect something else was to blame in the example you gave.

I'll have to check it out

You might try looking up a good masonry supply place - one that carries firebricks and so forth, and see what they have to offer.

Another option if you want higher temp stuff might be to see if you can find a place that sells pottery making supplies such as kilns and so forth.

We own 2 kilns and have used Sairmix-7 for builds. Expensive but works well.

Edit: Kathy said to look at Fiberfrax Fiber Bonding Cement

Guessing that McMaster-Carr carries some of that stuff - not always the cheapest, but the quickest and most complete selection.

Craig,

We deal with M-C all the time, seldom does anyone beat their price. Great place also for glass gaskets.

:bug: I think Bob would have a difficult time mortaring that into his stove! :roll:

I agree but it would be nice to utilize my heater for hotwater.
I did a search on McMasterfor refractory cement but didn't turn up much.
I'll probably go with either #36 mortar ( formerly Sairmix 7)or Saisset, or Sairbond not sure yet found this place it has good selection:
