    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.

    from Greensboro, NC asked:
    February 3, 2018
    Your product has been recommended to me to be used to attach a heat shield to my marble fireplace that is required for ventless gas logs in lieu of using screws. Is this the right product or do you have a better option?
    1 Answer
    Yes, a hi temp silicone sealant would work with an Elite Hood as they are fairly lightweight. If you were to switch products and use a heavier hood then I would recommend switching to a construction grade epoxy. However, Silicone will be easier to remove on the backend.

    How long does this sealant take to cure? How soon after a stove is rebuilt can we start to burn wood?
    1 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.

    Will this work for an exterior fireplace against metal and masonry?
    1 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.

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