What is the smallest size of flue goo you sell? I have a small repair. I need to bind a single fireplace brick to an existing motor. Is flue goo the right product?

I am looking for suitable refractory cement for building a foundry (for aluminum and copper) and will have a 2 1/2" - 3" wall of cement with 3" base and lid. Wall will be wrapped in 2" layer of kaowool. Will this cement perform well for this or is it strictly for more of a "mortaring" application

Answer:This product is indeed strictly for a parging or mortaring application and will not set properly at thicknesses beyond 3/4 of an inch. However, we do have access to a product manufactured by SaverSystems, known as Chamber Coat. This material has very good adhesion to reinforcement materials and can be cast in layers to achieve any thickness necessary. The product is rated for continuous temperatures of up to 2,600 degrees. Based on the melting points of the materials you mention, this should work well for you.

looking down from my chimney cap, I notice there are some small cracks two feet down in the flue; can this product seal those cracks in the flue?
By Will M. on April 17, 2017
Answer:There is no product currently offered for repairing the clay flue tiles as the damaged flue tile in question should simply be replaced. I recommend relining your chimney as an alternative to simply replacing the cracked flue as most stainless chimney liner manufacturers offer a lifetime warranty for their products and the the remaining flue tiles may start to crack after the top flue tile is replaced.

Do you know if this product could be used to glue fireplace glass to the interior of a fireplace? If not, do you carry or know of am adhesive or glue that is noncombustible or nonflammable that could be used?

Answer:This product is intended primarily to bond sheet metal and masonry products to one another in high temperature situations. I cannot recommend it for glass.
