    Somehow I just knew your firebox repair project would be a success. Congrats on a job well done.

    Good job! Working with composite material can be tricky. It looks\sounds like your got this beat.

    It's all gravy from here on out...

    So far so….awesome!! Holding temp, fuel load is looking good, passing 325 now, should get 350 no problem, plan on letting it just burn out from there.
    Chicken and ribs for Labor Day!! Count this one a win

    Well, here goes nothing. Got a small fire going, started on opposite side of repair. Running the pit fan to keep it steady. Grate temp sitting at 225, probes are on the repaired side. Gonna let it sit there for an hour or 2, run it up a bit maybe try for 350. We’ll see how long my small lump load will last in there. I really need to get an infra red themo. I would like to see how hot the firebox gets.

    This is outstanding info. Thanks.

    I am feeling ambitious enough to tackle this myself one day if the situation arises!

    Thank you, Philotius , for sharing your project with us as you go along. It's been very interesting. I can hardly wait for info about that first cook after the seasoning step is done and dusted.

    I bought the cement from Amazon, around $40.00 I had everything else. I highly recommend the steam cleaner I have a little hand held Bissel. Anywhere I did not steam clean, the cement did not bond.

    Some wooden mixing sticks, lots of gloves, the plastic I worked on was handy for clean up. Just a boxed roll of painters plastic. A spray bottle with a good misty spray. Some rags you wont mind throwing away. A small sturdy container to mix small batches of the cement. Maybe some dust masks? that stuff is very dusty. Of course the putty knife, possibly some wet sand paper - I haven't tried this yet.

    The first day I put about 3 hours into cleaning and assembly. Day 2 I spent maybe an hour cleaning and putting on another layer of cement. Day 3, another hour or so cleaning it up. Mostly just waiting for it to dry now. Our temp here kinda took a dip the last couple of days. So I guess - 4 to 5 hours of actual work. looking to be another 2 to 3 days before I will put a fire in it - so total time 7 days or so, if you have the weather on your side. Maybe faster if you can do it inside with some heat.

    Philotius, how do you plan on decorating the finished product?

    Another thing you can do to dry it out. Place it in the oven at 150 or 160 degrees for a few hours. Then bump up the temp 20 degrees every couple hours until you get to above boiling point. Start in the morning, plan to be done sometime that evening. Then let it cool overnight. Going slowly gives the ceramic time to heat soak, and water trapped will not turn to steam too rapidly.

    Also if you can, add an expansion slot. My Primo firebox has a cut out that runs from the air intake all the way up. About 1/4 inch wide. Or less. Just enough to allow for some expansion.

    I have a brand new firebox sitting in my garage. I only had to pay $50 for shipping thanks to the Primo warranty..

    Day 3: Just a quick clean up with a 1" putty knife to knock any loose material off, took down a couple of ridges. I can really see where the cement still has a lot of water left in it by the color difference.

    The putty knife with light pressure has done a great job taking loose material off finding any areas that have not bonded. Anything that doesn't scrape right off, I've been leaving alone. A quick rinse with the hose and it's looking good.

    I may do 1 more skim coat. I was thinking of screening some of the bigger chips out of the cement to make a nice smooth topcoat. I may be picking fly crap out of pepper though, probably doesn't need it. I might try wet sanding with some 400 grit drywall screen, see if that smooths things out. I just think that the roughness will attract more gunk build up.

    I used the existing holes in the firebox and wired mine together. It's been going strong for years now.

    Impressive. That there firebox is gonna look like new when all is said and done. As long as it holds up to the heat you should be good for years to come.

    This is a great thread for anyone with a ceramic grill.
    I have two, both purchased used so no warranty on either.

    Good luck when you fire that puppy up.
