I'm Peter Reinhart! Ask Me Anything! Monday, February 15, 2016 7:00-8:00 pm EST

To kick off our AMA feature, we have invited author, chef and master bread maker and host of Pizza Quest, Peter Reinhart, to be our first host! Peter will be in the Forum on Monday, February 15th, from 7:00 - 8:00 pm EST. If you are unable to be online during the live session, you can post your questions in the sticky post. Peter will answer those questions during the live session on February 15th. You can view Peter's answers to your questions as well as what happened during the live session in the session thread.

Ask Me Anything New Forum Feature

You will notice a new forum at the top of the main page called, "Ask Me Anything". This forum will be used for live one hour "Ask Me Anything" (AMA) sessions hosted by people who are knowledgeable in different areas pertaining to wood fired ovens. How it works:
- Each AMA will have a "sticky" thread where the community can post questions they would like answered during the live session. This will allow everyone to participate even if you can't be online for the live session. These questions will not be answered by the host until the live AMA; if you need an answer quickly, you should post it in the appropriate Forum area for the community to respond.
- Another thread will be posted for the live AMA. Registered users who are logged in during the live session can interact with the host by asking questions and receiving responses.
- The live thread will remain in the AMA forum to view after the session.

We hope you enjoy this new feature! Please let us know if there is a topic that you'd like to have as an AMA and we'll look for a host!

  • Need help with stucco & vent

    Hi All,

    (I moved the thread to this new location)

    The oven is nearly done and we've framed the outside with steel studs and Hardibacker board. It is the type used for bathrooms and wet areas. Could you recommend the steps for placing stucco on the backer board? Does it need primer, metal lath or chicken wire?

    The enclosure has a peaked roof and looks somewhat like a childs play house. The sides are 52" x 60". It will have metal roofing. Is ventilation of the roof area necessary or can I close up the seams all around when I apply stucco? Just wondering if moisture could get trapped inside the enclosure and cause a problem. If a vent or two is necessary could you recommend the size and correct placement?

    Cheers,
    Bob

    I have seen another post like that in one of the other topic areas. I would check the Pompeii area or search for brick vent. My understanding is once cured, you do not need a vent. Plus, you dont want wildlife taking up residence ;-)

    As for the lathe and everything, you will need chickenwire as a support - when my ICF house was built, the stucco went on the wire which provides support.

      Hi All,

      Here's an update on my build. I hired a fellow to help me with the stucco work. It was an interesting experience to learn his technique and wipe on mortar with a trowel. It is finished with a sponge trowel to bring up a sandy surface, looks nice. Today I drilled holes in the top edge of the walls for press-in vents. The roof cap has open areas for ventilation too. I'm satisfied there will be good circulation. BTW. I used a bale and a half of mineral wool insulation (to fill voids) and 11.5 cu ft of perlite around the oven. This is in addition to a thick layer of perlcrete 7:1 around the dome. When the stucco has a few more days curing on it I will cover the walls with an elastomeric latex masonry paint. Then, It will be done. I've already had a few curing fires in the oven. I'll put the construction photos into a folder and post them soon.

      Cheers
