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.

I purchased this for a wood-burning stove in my house as there were a number of bricks that had to loose. It worked great for that and I intend to use what’s left over for a forge that I have all things considered this does what I expected it to do and I’m very happy with it.

I used this product for my in home fireplace repair. Was easy to apply and durable. The base of my fireplace was falling apart. I did the repair on my own. One time application did the trick. Easy clean up (a little sticky) keep children and animals away. Store container in a safe place for future use

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 refractory cement seems fine, but Amazon shipped the two buckets on their side, so some of the cement leaked out in transit. It isn't worth the hassle and wait to return them. Come on Amazon, don't you understand how buckets work?

This was premixed so it was very easy to work with a putty knife. Spread easily and filled cracks in my firebox. No mess due to not having to mix with water.Will paint with rutland 1400deg black paint

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.

The fire bricks in my wood furnace were cracked and loose and on the border of crumbling (see pic); so instead of hiring a contractor and having to wait a long time and pay a lot, I decided to tackle this on my own. I followed the instructions exactly and the results were fantastic. All of the firebricks are now secure and the cement cured properly. Just follow the instructions and don’t let the fire get too hot too fast. I used a silicone spatula to apply the cement as that gave me a lot of flexibility to work between the ridges and cracks of the firebricks.I had plenty of product left over, even with two applications.

Fácil de usar y funciona muy bien.

I’m using this to fill cracks in my hobby furnace (Devil Forge) cement refractory lid. This is absolutely the best product for my purposes, thank you!

If you are trying to fix cracks in your fireplace this will work, that being said it's not super user friendly, after you apply it you have to slowly, and I mean slowly heat it up so it doesn't bubble to cure the compound.But that being said it's the inside of a fireplace it just needs to be functional not an art piece.It will work.

Very thick cement, looks like it will be great for my foundry build.Container has about 3 liters of cement in it.
