Fire brick alternative

[cookswithfire]

Has Anyone used high temp refractory cement in there smokers. I thought I would trowel a layer under the firebox and a layer on the bottom of the smoker maybe even create a slight V shape to a drain?
Is this folly or feasible?
Thanks

I did it this weekend
I wasnt good enough with a trowel to get the drain action I wanted in the smoke chamber..it was pretty thin I went thicker in the firebox and added
3 parts mason sand to the mortar. I will see what a difference it makes nrxt weekend
Cheers!

CWF:

Sounds highly feasible. Given a coating of grease before applying, it should remove rather easily as well I think (if it doesn't work). If you do it, please take "before & after pics" so you will be eligible for the cool mod of the month prize (assuming it works).
