Can this mortar be used to patch firebrick in a firebox of a fireplace? About a 4 by 4 inch patch.

Asked by: RAD
Yes. This will work if the patch is properly heat cured in accordance with the manufacturers instructions.

Can this be used in place of a baking stone in a pizza oven,say I want to mold it in a circle and lay on top of a grate.

Asked by: RJ
You're looking for castable refractory cement, such as one of the kast-o-lite products. Check the temp and refractory properties of those to find the right one for your need.

Asked by: mike
Yes, it hardens and bonds to an existing surface very well when heat cured.

This was recommended as an alternative to refractory mortar, which HD no longer carries, so I used it to bond a series of fire bricks edge to edge to close off the top front of my firebox. I wet the edges, laid it on, set them together, let them set up for an hour or so, then baked it all day over a 250F fire, and the stuff has about as much bond strength as chewing gum. It can be used to seal gaps and fill cracks, but is utterly worthless as an adhesive.

I troweled-on the product after cleaning all of the surfaces inside the Zero-clearance firebox. Then I lit a fire and waited for about an hour. The Furnace Cement cured beautifully and now, I don't have to replace the sheets of firebrick. This product is easy to use, if you follow the simple directions on the container, easy to clean-up with soap and water, and looks like it will last for a long time. I have already recommended this product to my brother-in-law and I will continue to recommend it.

However, more info on curing the needs to be on the container. It does not mention that this product has to be "fire" cured or it will not set (harden). I did call Customer Service and they explained how to properly cure the furnace cement.

The product is a good product, but the instructions for curing are incomplete. When I called the company they were out of business and another company bought them out. Hopefully they will include an instruction sheet in the future on how to cure the drying.

Product is good but the Home Depot packing and shipping is the worst I have ever seen. I had made multiple orders and all but one order was returned because of poor packing, tubs were loose packed and lids came off in in shipping.

I find it holds up under the intense heat without cracking. And as long as you put the top on tight, it will last until the container is empty. Good stuff.
