Fire Cement Help

Recommended Posts

Not sure if I have the right forum here. But it didn't seem appropriate to post this in any of the others.

I am building a Tandoori oven out of an old oil drum. I've initially lined it (Thickly) with a regular cement and broken glass mix. This has dried off and now I need to line the whole thing with fire cement and smooth it off. The first attempt at this was a complete failure. We got major cracks appearing all over the Fire Cement and had to strip it back. Not sure if we need to add some sand, some plasticisor or spray it down with water to try and let it dry slowly.

Has anyone on here got any experience with Fire Cement? Any way to stop it cracking like that?

Looking forward to some suggestions.

Have a look here http://piers.thompson.users.btopenworld.com/building.html

Indian tandoors are generally lined with unfired clay (it gets fired when you operate the thing for the first time). I'm not sure that fire-cement is intended to actually render large areas, I thought it was for joining fire-bricks together, I suspect that is where things are going wrong :o

There is a thread on another Thai related site showing people using the standard Thai pots as a tandoor-like cooking vessel with some success, if the pot cracks badly it's simply replaced (cheap as chips).
