    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 Questions & Answers
    By Shawn from New Jersey on December 3, 2012
    I just repaired the joints inside my fireplace two days ago with your product. My question is, can I paint over the Rutland mortar repair with high temp paint before lighting a fire?
    By Collin C. - NFI Master Hearth Professional on December 4, 2012

    Answer:
    This item must be heated to its 500 degree cure point before it is fully set. This will need to be done first and foremost. Furthermore, the mortar is not designed to be painted over. Most paints will not adhere to the mortar over an extended period, due to the high temperatures in the firebox.

    This is especially true with wood fires. If the mortar must be painted, a high temperature ceramic paint is likely the only product that will offer some longevity.

    I have a wood burning stove with an air pipe entering from the rear. That firebrick has cracked with a piece broken off but still in place. Do you recommend that I remove the brick, and use mortar to mate the parts together and fill in the remaining cracks? This brick is expensive and was just replaced about 2 months ago. It appeared to work fine for many fires but now is damaged. I believe the remaining mortar will be about 1/4 inch thick at the most. The instructions on the Rutland Fireplace Mortar tube are not very thorough or clear regarding an installation. This is more than filling a surface crack but I believe a "mortar" should do the job we need.
    By Collin C. - NFI Master Hearth Professional on December 20, 2013

    Answer:
    This product can indeed be used to join the damaged sections of brick. For best results, it is recommended to keep the thickness as close to 1/8 of an inch as possible. The mortar must also be heat cured immediately after application. As such, you will need to burn a fire in the stove after the brick has been repaired and installed again.

    By Ken from Fresno, CA on November 28, 2012
    How do you go about the heat curing process?
    By Collin C. - NFI Master Hearth Professional on November 28, 2012

    Answer:
    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.

    I have a cast iron wood stove (Upland #207 circa 1978), that needs sealing on the side panels at the corners. What should I use? The old stuff falling out looks grey and like a fine mortar/ grout.
    By Collin C. - NFI Master Hearth Professional on October 24, 2013

    Answer:
    If you are referring to the inside refractory side panels, this would be an excellent product to use for repointing the corner joints. The product is easy to work with and can bridge up to a 1/8 inch gap.

    By Bob from Westfield Ma. on September 4, 2013
    Just built a brick pizza oven. I have some voids on the inside of the oven that I would like to fill in with high heat mortar. I was told by the oven supplier that the mortar would just eventually fall out? Would your fireplace mortar work?
    By Tyler M. - NFI Certified Specialist on September 4, 2013

    Answer:
    For your pizza oven, we recommend the Rutland Stovo Fireplace, Stove, and Furnace Mortar - 1 Quart Tub.

    By Freddy from Southern California on February 24, 2014
    I have a woodburning fireplace. The firebox mortar is falling out in spots, with "see-through" openings between firebox bricks into the space between the firebox and the outside brick structure (which is inside the house, not external).

    Will the Rutland Fireplace Mortar 10.3 oz cartridge be okay for these large gaps or should I be using the Rutland HomeSaver Flue Goo Pre-Mixed Furnace and Refractory Cement?
    By Collin C. - NFI Master Hearth Professional on February 25, 2014

    Answer:
    This product can indeed be used to repair small cracks and gaps, but it is very limited to the 1/8 inch gap size that is mentioned. Any larger and the product will not fully cure. For larger gaps, the Flue Goo is an effective product to use.

    By Tom from Madison, VA on June 21, 2013
    Can I store this mortar tube until the fall and apply it then?
    By Collin C. - NFI Master Hearth Professional on June 21, 2013

    Answer:
    Because this product has a shelf life of approximately 18 months, storing it until fall should not be an issue. This manufacturer typically sells all product by the time it has been in inventory for 3 months.

    By Jennifer from Okoboji, IA on August 27, 2014
    I have a rock outdoor fire pit. Several of the rocks have come lose from the original concrete mortar. I need a product that will withstand high temperature, is flexible, and that will bond to rock/stone as well as the original concrete. . Will this product work?

    By eFireplaceStore on August 27, 2014

    Answer:
    For the criteria mentioned, the best product to use will be the Rutland Castable Refractory Fireplace Cement - 12.5 Pound Tub. Unlike the mortar you are viewing now, this cement will hold up well in an outdoor application. It also has the heat resistance and bonding characteristics you require.

    By Lorie from CA on May 14, 2016
    Does this product come in a clear color?
    By eFireplaceStore on May 16, 2016

    Answer:
    My apologies, but this product is only offered in black, buff, and gray colorations.

    By Dean from Kansas City, MO on September 30, 2015
    I'm building a firepit and I'd like to use this Rutland fireplace mortar for the pavers that will surround the firepit. Is there a temperature range for the ambient outside temperature in order to use this product correctly? Should I use this only when the outside air temperature is above 40 degrees Fahrenheit?
    By Brennan W. on September 30, 2015

    Answer:
    This product would be appropriate for your use if your firepit is covered. If your firepit is not covered, this product would not work as it is not meant to be exposed to the elements.

    By Everett from DeLand, Florida on October 13, 2013
    Can I use this product as an adhesive to construct my outdoor fire pit?
    By Collin C. - NFI Master Hearth Professional on October 14, 2013

    Answer:
    Per the manufacturer, this product is not recommended for an outdoor application, as humidity has a negative effect on its durability. While it is not available in a caulking tube, the Rutland Castable Refractory Fireplace Cement - 12.5 Pound Tub will work well for outdoor applications.

    By Brian from PA on December 23, 2014
    How do I caulk the area between the metal surround of my glass face fireplace doors to my brick fireplace?
    By eFireplaceStore on December 23, 2014

    Answer:
    Normally, the small gap between the metal door surround and the brick facing of the fireplace is not sealed, as most door assemblies will be shipped with fiberglass insulation to pack into the surround. If you do want to seal the gap, a gunnable mortar like the product you are viewing now could be used.

    By Angela from Indianapolis, IN on July 12, 2017
    It says repair. Can this product be used to rebuild the back wall of the firebox?
    By Owen on July 13, 2017

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

    I would recommend this item to a friend.
    I used the whole tube to repair and restore my fireplace brick finish, which were severely damaged and cracked and chipped from years of burning hot Oak wood. The mortar was easy to work with and shape, I let it cure for a week then had a small fire for 3 hours to cure it, and now its as hard as the original brick and is holding up very well. I will order this again in the future if I get bad bricks on other walls or areas of the fireplace.
    Pros:
    Easy to use, color matched the bricks I have.
    Cons:
    Nothing.
