Looking awesome! Quick question, are you not concerned about the firebrick being exposed to the elements during the winter? Like, it it rains, and the fire brick drinks up all the water, then freezes, couldn't it crack a brick? (Sorry to instill fear)

Made about 30 pies yesterday evening. My wife made scones this morning and I've got some bread going right now. It's incredible what you can do with just one fire.
It's also pretty awesome that while the inside of the oven walls are over 1000 F, the outside stucco layer is cool to the touch.

The temperature is changing and the leaves are falling. I was hoping to find a day warm enough to finish the stucco but it's not looking promising.

I just checked the weather and it's looking like my nice days are coming to a close for a few months. Are there any issues with waiting 3-5 months between the brown and finish layers? Our lows are in the 40s now, but starting Thursday it looks like they will be consistently in the 30s and below.

This smooths out any tooling marks and creates a waterproof finish.
There are lots of different approaches so don’t have to follow my method.

I think I better go with the Quikwall for my finish layer to be safe.

Maybe I should use this as my finish coat instead for the fibers and extra waterproofing?

....Do you think I should wrap this coat in the hardware cloth.......?

Originally posted by Gulf View PostI think that you are hanging stucco over chicken wire.
Yes, the only wire I used was chicken wire. I do have some hardware cloth I could use... Do you think I should wrap this coat in the hardware cloth and do one more brown coat over that before the finish coat for added strength? I might run low on real estate in a couple places, but I think I can make up for that by cutting the brick veneers a little thinner in those few spots if I have to..

I did three layers, but not like the stucco schedule. The mesh that I used was spaced from the vermicrete. I skipped the usual scratch coat and smoothed each layer.. Between layers I used an acrylic fortifier bonding agent. It was also used to replace a lot of the water in each layer. Though, I used a stucco mix, (with some added portland) my stucco layer is more like a ferocrete.
.....It feels strong after the scratch and brown layers. Does the finish layer provide anything more than just a little more mass?.....
Also, the tarp will be ok. Just keep it covered to protect it from the sun and drying breezes. It needs the moisture to cure properly. But, you don't need to keep wetting it if you keep it covered.

david s I fought the cling wrap in the wind, but I lost the battle. I hydrated it the best I could and covered it with a tarp. Should I continue misting it for the next week or so?
