Refractory Cement Coating Inside of Dome

Re: Refractory Cement Coating Inside of Dome

I coat the inside of my cast oven domes to give a smooth white finish. I've found that the mixture must be applied when the surface has the correct moisture content, ie. not too damp, but not too wet, otherwise it will flake off, not dry or adhere properly. Achieving this is difficult, but when done correctly leaves a perfectly white surface, much like a kiln wash on pottery shelves, which looks pretty dramatic when it begins to clear and also provides better reflection from the flame to light the interior so you can view cooking better.

Ultimately you will be proud of your brickwork. Regardless of gaps. It can be messy as all get out, but it is still beautiful with a flame and some food in there.

Seriously.

Thanks for the responses. I didn't see anyone else on the forum do this so I figured it probably wasn't a good idea.

It won't stay bonded and it will fail.

I would not recommend that.
Basically the masterpiece that you will see IS the inside of the dome.
Even if the bricks aren't perfect it will still look better than refractory cement.

Good luck.

I was wondering if using refractory cement to make a smooth coating on the inside of the firebrick dome would make any sense. This would help fill all the inside gaps and also could be used to make one continuous smooth surface on the inside of the dome. Anyone ever do this or have any thoughts on the pros and cons? Obviously my concern would be with the cement falling out into anything that's being cooked.
