    Challenging projects demand the best quality products. For occasions when you need a really tough, yet elastic seal we recommend Rutland High-Temperature RTV Black Silicone Sealant. Its chemical resistance and ability to remain flexible when exposed to 550 degrees fahrenheit temperatures make this sealant ideal for jobs like sealing chimney tops, pellet stoves, and gas fireplace inserts. A neutral, odor-free formula also makes this hearth maintenance product a good choice for applications in confined areas with little air flow.

    By Dave from NJ on October 9, 2014
    The refractory panel in the back of my fireplace is cracked as well as the base. Can this product be used to fix these cracks?
    By eFireplaceStore on October 9, 2014

    Answer:
    This sealant will not work well for your purpose. Instead, the Rutland Masonry Fireplace Patch - 1.5 Pound Tub should be used. Please keep in mind that this will only be a temporary fix, as the panels will likely continue to degrade and will eventually require complete replacement.

    By Louis from PA on October 21, 2016
    I used Rutland 500 degree silicone on the inside of an insulated pipe that goes through the wall for my coal stove. The pipe had a gape in it and I wanted it sealed. My stove guy said you can not use this in the pipe that goes through the wall because it will melt and catch fire. He wants me to replace the pipe, or scrape all the silicone out of it. I scraped 96% off the pipe. Should I replace the pipe, or is scraping 96% off of it good enough?
    By Chris C. on October 21, 2016

    Answer:
    I would indeed utilize a wire wheel or some other method to remove the additional sealant from the pipe prior to using the appliance again.

    By Ed Simon from Maryland on January 23, 2012
    I need to caulk around my fireplace doors. The mortar keeps falling out. The gap between the metal door and the limestone is about a 1/4". Will this product work and does it come in different colors? The limestone is a sand color.

    I believe the metal door expands and cracks the mortar joint so something flexible like high temp caulk may work.
    By Kevin E. - Fireplace Specialist on January 24, 2012

    Answer:
    For a gap this large, a gasket and cement combination may be a better solution. The gasket material will work to fill the gap and the cement will absorb the flex of the door kit. Please follow the below links to view these products.

    Will this work for an exterior fireplace against metal and masonry?
    By Collin C. - NFI Master Hearth Professional on September 24, 2013

    Answer:
    This product can indeed be used to seal exterior joints, as long as they are not exposed to a temperature greater than 550 degrees. This RTV sealant can indeed be used to bridge masonry to metal joints.

    How long does this sealant take to cure, and how soon after a stove is rebuilt can we start to burn wood?
    By Collin C. - NFI Master Hearth Professional on October 4, 2013

    Answer:
    This item takes approximately 24 hours to cure and should not be subjected to heat within the first 72 hours.

    Please keep in mind that this sealant will likely not have a high enough heat rating for a wood stove. If you are rebuilding a wood stove, Rutland Pre-Mixed Black Furnace Cement - 10.3 Ounce Cartridge is the better product to use.

    By D from Washington, DC on June 4, 2013
    Can I use this to replace the gasket on the glass for my gas fireplace?
    By Tyler M. - NFI Certified Specialist on June 4, 2013

    Answer:
    We recommend using the Rutland E-Z Spread Fiberglass Stove Gasket Cement for your application.

    By Brandon from WV on November 26, 2015
    How long will it take for the smell of this Rutland high-temperature RTV black silicone sealant to go away on a wood stove single-wall stove pipe?
    By eFireplaceStore on November 27, 2015

    Answer:
    Typically, RTV is not utilized at the joints on a wood burning venting system. The venting system can easily exceed the working temperatures of RTV, causing the product to emit a strong acrid odor that will not diminish for quite some time. Instead, a product like the Rutland Pre-Mixed Black Furnace Cement - 10.3 Ounce Cartridge should be used. It is usually only needed at critical points, such as where the stovepipe meets the appliance and at the transition to the Class A chimney.

    I have a wood-burning stove, and I hated having smoke leaking out of the flue. This one worked great and fixed the problem.
