castable keystone cure - 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!

  • castable keystone cure

    Wondering if the castable keystone that I have used for the top of cook dome will need extra dry time before I stucco.

    Dome complete 2 days ago and now I am doing the entrance arch and vent work. I plan to insulate in about 5 more days and start curing. After a week of curing I will do the first coat of stucco.

    2 questions I have regarding this next stage.

    1.Is my castable plug keystone about 10" in diam and 4" in thickness going to need extra time to cure before stucco.........like more than the fire brick igloo and mortar cure.

    2.Would it be a good idea to leave a small hole in the stucco at the very top of dome for a few months just to let out any possible steam or extra dampness that may be in the oven as it cures and dry out during the start up of the use of the oven and then plug that small hole later on say a month or two down the road? I could even plug a half inch hole with a caulking or something down the road.

    Thanks for this Wayne

    1. Castable only needs 24hrs to cure, but you do need to drive the water out slowly m'factureres recommend no more than 50C/Hr
    2. A hole in the top is a good idea and even better if you can make a permanent arrangement to help remove moisture after heavy rain. Someone on the forum has done this and reports good successs. I have a system around my flue/outside shell that does this job too. works well.
