Product Details

Manufacturer: Rutland
Rutland Part Numbers: 63B
Item Number: RUT-63
UPC: 022624002635
Need to make some minor fireplace repairs? If you're looking to patch broken firebrick or repoint a firebox's mortar joints, there's no better choice than this Rutland Fireplace Mortar. Heat curing allows this tough mortar to withstand temperatures as high as 2,000 degrees fahrenheit and become as hard as the firebrick you're using it on. A smooth texture and a cartridge that will fit into any standard caulking gun also make this mortar extremely easy to apply. You even have the option of painting this remarkable compound to match the finish of the firebrick once it has set.

Please Note: This mortar contains sodium silicate 1344-09-8. It should not be used without safety goggles and chemical resistant gloves.

Customer Q&A with Product Specialists

Jessica from asked:
Can I just have this air dry?
Can I just have this air dry?
Yes, this product can be set up by air drying. It won't be exposed to very much heat, so I would recommend letting it set for at least a few days for your purposes.

Marc S. from Longmont, CO asked:
What is the best way to heat cure it?  How long does it take to heat cure?
What is the best way to heat cure it? How long does it take to heat cure?
Per our specialist, Collin, "After allowing the product to dry for at least 24 hours, you will need to build three consecutive fires of increasing intensity. It is best to build one fire per day, but the process can be rushed a bit, as long as the fireplace is given time to cool down completely in between fires. The first fire can be built just with kindling and only needs to achieve a couple hundred degrees at the surrounding firebox walls. The next two fires can be larger and should heat the walls to 300 to 400 degrees and 500 or over, respectively. By building fires in increasing intensity, this will help to keep the mortar from cracking or separating prematurely."

That would depend on the size of the repair. This product is also available in a larger size.

Can I use this product as an adhesive to construct my outdoor fire pit?
Per the manufacturer, this product is not recommended for an outdoor application, as humidity has a negative effect on its durability.

Fireplace Mortar That'll Last You Years

This FireRock Adhesive Fireplace Mortar did exactly as it stated it would when I bought it and sealed up the crack in my firebox perfectly. The crack has yet to reappear, and that was over 5 years ago. I bought this mortar again to repair another crack that appeared at the back of my firebox and I know it will work just as well as the first time I used it to seal another crack.

Reliable Mortar for Fireplace Repairs

This mortar applied smoothly and dried quickly, making it easy to patch damaged areas on my fireplace refractory panels. The instructions were clear, and I found using a torch to cure the material helpful. Just be sure to keep the flame away from the dried mortar to prevent bubbling.
