Rutland Refractory Cement 64 Oz - Fiber-Reinforced Pre-Mixed High Temperature Cement for Fireplace, Wood Stove & Fire Brick - Made in USA, Buff, 4 Lbs

I ordered this cement for a Kamado, ceramic Chinese BBQ oven, that I was restoring as I found some blog posts recommending refractory cement as the best way to repair broken or cracked pieces. If you are familiar with these types of ovens (Kamado, Big Green Egg, Kamado Joe) then you know there are two internal ceramic parts that create the firebox. These parts on the BBQ I was given were each broken into about 20 pieces and I wasn't sure if I could even rebuild the puzzle. After some thorough prep work and getting the puzzle pieces organized I began the rebuild and "gluing" the parts together with the cement. The assembly went great and the final product, while maybe not pretty, is extremely strong and has so far held up to one cooking up to 400 degrees for several hours. I am curious to see how the product holds up over time with all the heating and cooling but so far am very impressed. I would certainly recommend this product for this type of repair and hope that it keeps the parts together over time. One important note for this cement is the recommended curing process which is basically a slow stepping increase in heat to allow the product to properly cure. I assume this step is to make sure all moisture in the ceramic, from the cleaning and the cement itself, is driven out and doesn't make the repair fail from steam. I couldn't figure out a good way to do this so instead I placed the completed parts in full sun for many weeks assuming that this would get them nice and dry - so far no issues.

Easy to spread - filled in pretty big cracked up floor of fireplace it was all crumbled.. cant shell out 1000 just yet for new fireplace inserts.. this got it back into shape for another few years!! Worth it. It’s nice and creamy - spreads like margarine. I Let it dry a couple days. Some areas were little less than inch deep. I just coated the whole bottom.. why not for extra measure!

The fire panels in my fireplace were broken. I didn't realize when I bought it as they stuffed the fireplace full of wood for aesthetic. Anyway you're not supposed to use this for big cracks or gaps. Bit I used it to bind two pieces bag together and fill a large missing section. It held up all winter and saved me hundreds in replacement cost. I'd say if it lasts through a winter burning wood nearly 24/7 for four months it's worth it. Once wood was burned a few times the whole thing was black and you couldn't tell there was patching done to the panels. Works fine and lasted all winter.

Used this to remortar our 64 yr old fire place. It is peanut butter consistancy. Viscous and hard to keep sharp lines with. Cures by having a fire. Too hot too fast causes bubbling. Just did a yr 2 touch up on other spots. Solid product.

Product works great. Spreads smooth. Dries pretty quickly. The 3 star rating was because of how it was shipped. As you can see in the pictures, "The Grippers" worked-ish. They worked where they were put on (should have used 4/5 of them) but the cement got on everything, including my spark plugs! Just happy they triple packed those and no cement got on them. The box was beat up and very flimsy by the time it got to me. Whatever packing tape was used definitely did its job by keeping everything in. Next time I may just get this at the local HD/Lowes. Very lucky it made it to me in one piece.

I got a great deal on a cracked ceramic kamado style grill and used this product to repair it. The crack began on the rim where the spring loaded hinge attaches to the dome lid. I had a few of the broken pieces, but there were gaps up to an inch that had to be filled. The end result isn't pretty (the repair bubbled on the inside of the dome and is a different color than the outside of the grill) and I had a bit of peeling on the inside where perhaps my application was too thin, but I've used the grill a few times and it is functioning perfectly.The only downside is that I used maybe 1/10 of the tub and the instructions say it's not for storage. It'd be nice to be able to purchase in smaller quantity so there is less waste.

Handles heat well

Got new stones to go with this and rebuilt the entire inside of my fireplace and it looks amazing.
