    from Wheaton, IL asked:
    March 23, 2015
    Can I use this product to coat a refractory panel in the back of my wood burning firebox?
    1 Answer
    This product can indeed be used as a thin coating to damaged refractory panels, although the difference in heat expansion between the product and the panel means that the solution may only be temporary. The product should be cured immediately after the initial drying period to ensure maximum hardness.

    Can the refractory fireplace cement be used to repair the floor of my wood burning pizza oven? It has become pitted and I need a "skin coat" to smooth and level the floor.
    1 Answer
    To withstand the temperatures produced by a wood stove, I would recommend using furnace cement.

    from OR asked:
    November 17, 2014
    I am trying to heat cure some repairs to a firebox using refractory cement but I will not have a fire until after I can have this cured and painted. Can I cure this with a space heater and, if so, for how long before painting it with a high temperature paint? If not, what other options do I have knowing that I cannot build a fire until after I have painted the surface?
    1 Answer
    Unfortunately, a space heater will not be able to provide the necessary temperatures to cure the surface properly. To be honest, building a fire is the only way to cure the product, as it requires constant exposure to 500 degree heat for at least an hour. The fire can be kept fairly small and confined to keep from getting the surface dirty.

    from Bergen County, NJ asked:
    October 15, 2014
    I have a 100 year old fireplace with what appears to be cement covered bricks lining the firebox. This past winter several patches of the concrete flaked off ( 2-3 inch areas) exposing the underlying brick. Can this product be used to recover the brick and blend or smooth over onto the remaining concrete?
    1 Answer
    This product can indeed be used to resurface the interior of your firebox. I highly recommend using a chisel and hammer to break loose and remove as much of the existing cement as will readily separate. This will help to prevent additional separation from beneath the new cement, which would result in new cracks forming.

    from St. Paul, Minnesota asked:
    May 20, 2014
    I live in Minnesota and have an outdoor fire pit. Can this product be used to adhere to brick on top of brick with all of the inclement weather we have in MN? The bowl which sits on top of this brick holds the wood to be burned. The bricks are 11" x 7" x 9" and 2" thick and there are 11 of them forming a circle.
    1 Answer
    Per the manufacturer, the Rutland Castable Refractory Fireplace Cement - 12.5 Pound Tub is the product that is best used for outdoor applications, especially in harsh conditions. The castable cement offers good adhesion and is non-porous, which helps to prevent breakdown from ice intrusion.

    from Lexington KY asked:
    April 19, 2014
    How do I heat treat the repaired joints?
    1 Answer
    For a wood burning stove, the best method is to build a compact, hot fire. Exceeding 500 degrees is not a problem, but the fire should be kept as compact and dense as possible, to prevent any ash or embers contacting the cement.

    from Woodbury, CT asked:
    September 30, 2013
    Is this the right product to patch solid stone/granite fireplace bases (with ash clean-out trap doors)? Over time, the bases in two of our fireplaces have worn into concavities under the fire grates. They have been patched by previous owners, and that cement is now crumbling away. The areas are approximately 3/4" deep and 8' - 12" wide.
    1 Answer
    This product can indeed be used for this type of application. However, I do recommend layering the product, as covering the indentation in a single 3/4 inch deep layer will likely yield the same results that you are experiencing now. Adding the product in a single 1/2 layer is acceptable, then adding a second layer when the first has had approximately 1 hour to begin setting is the best way to proceed.

    March 13, 2013
    My fireplace is 40 years old. I've never close the vent. The back wall has cracks in it and I was hoping to repair it myself with the cement. Is this possible or do I need to get a new liner for the back wall?
    1 Answer
    You could use this product or the Rutland Masonry Fireplace Patch to repair any cracks or holes.

    Robert Roelle
    from Huntington, NY asked:
    February 11, 2013
    Where the fireplace box meets the hearth, there exists a gap of about 5/8 inches wide and 4 inches deep. Is there a fireplace mortar that can be used for the 4 inch deep gap that I need to fill? If not, Can I use a regular concrete patch to fill most of the gap, allow it to set, and then top the gap with the refractory product?
    1 Answer
    Per the manufacturer, this gap could be sealed with the Rutland Castable Refractory Fireplace Cement - 12.5 Pound Tub. The product would need to be applied in layers of about 1 inch at a time, then allowed to set for approximately 1 hour before applying the next layer. This product makes an excellent, long lasting seal of large cracks and joints when applied in this manner.

    from Pennsylvania asked:
    November 1, 2012
    I have a homemade box stove and I don't know how to line it with fire brick. I have the bricks and cement. Do I lay the brick on a bed of cement for the bottom? Do I leave space between bricks? And the sides I have to go 3 bricks high. Do I put cement on the back of the brick and slap it in ?
    1 Answer
    We recommend contacting a local mason for more information regarding your construction. We only deal with manufactured wood stoves. We apologize for the inconvenience.

    Can I use this to adhere firebricks to a concrete block fireplace. If not, what do you recommend?
    1 Answer
    This product can indeed be used to set and finish firebrick to a cement pad or block fireplace. Please keep in mind that the fireplace will need to be heat cured to at least 500 degrees, within a week of using this product.

    I have a wood burning fireplace that has a tile floor and I was looking to update the tile. If I were to rip out the tile and replace it with a new tile floor, what would I use for the mortar bed and what could I use for the grout? Could they be the same product? If so, what product?
