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.

Fixed the Leak
October 6, 2009
I have a wood-burning stove, and I hated having smoke leaking out of the flue. This one worked great and fixed the problem.



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.

Gasket (also available in other diameters)

Cement (unfortunately, only available in black)

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.

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.
