Re: Oven dome will not go white

Sorry, my friend built it. He made the dome with bricks covered the dome with cement then he put insulation then more concrete lastly stucco.

I think we're getting somewhere now. After a long fire is your dome exterior hot to the touch?

Your only option would be to fabricate a sleeve to fit in the flue that would extend down into the oven, but even that may not work.

I am putting on a fire tonight so I will check. I don't believe it is hot to touch though

Re: Oven dome will not go white

How are you protecting the oven from rain? If you used regular stucco as your final layer that can soak up moisture over time and down to your insulating layer.
Find out from whomever built your oven about the insulation used and how much.

I will. Thanks again. Here are more pictures that might help.

Good, the vent/chimney is fine. In your last picture, I can see dampness coming out of the oven and into the stand. You probably need to seal the whole thing, and maybe try a long medium fire to dry it out.

It was raining last night so I am not sure that it is coming out of the oven. What do you seal it with. I am doing a long fire tonight.

If it is cementious stucco use something like Prime-A-Pel, but that will not bridge cracks. If it has cracks use an elastomeric paint.

The oven design looks good. It may not be fully dry yet. The fire has to be pretty big like this:

What are you doing to prevent rain from entering the front and soaking your oven floor?
So far, it basically seem like you have yourself a wet oven.

Just did a fire and it is been going for awhile and it is only warm to touch

"What do you seal it with."

I agree with George. For starters, keep your oven covered with a tarp or sheet of poly between uses. Ordinary stucco is not waterproof or even very "water resistant".

Even when dry you need a BIG fire to burn it "white". About 1 cubic foot of wood split down to 3 inch diameter in all at once. You should stuff so much wood in that just about touches the sides and top. The flames should be licking out the door.

Re: Oven dome will not go white

Thank you to all for help with this issue. I will be using a tarp until I can seal it in the spring next year.

Thanks again.

Elastomeric paint over stucco will make a huge difference. A dry oven is a happy oven. I learned that one the hard way with wet stucco and oven floor, too.
