Cinderblock to cementboard transition - Forno Bravo Forum: The Wood-Fired Oven Community



New Forno Bravo Forum Feature

Forno Bravo Forum Community,

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.

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.

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!

  • Cinderblock to cementboard transition


    I was wondering if anyone who has done the steel framing to box in the oven has had any problem with cracks in a stucco finish? Someone mentioned having the blocks go up to a certain point and then meeting the cement board will cause a crack along the joint.

    I did exactly as you described and didn't have any problems with the transition. Make sure you tape the gap between the concrete blocks and cement board. Also, tape ALL cement board seams.

    A have a few small stucco cracks in the back of my enclosure where I didn't bother taping the seams (oops).

    Good luck!

      I did the same - no issues -

      I used fiberglass tape at the transistion of the two materials and then used fiber reinforced render to coat the two surfaces (surface bonding cement).

      On top of that I put a final coat of a flexible stucco and it's looking great in year two.
