Can i burn coal on this cement?
By Kevin E. - Fireplace Specialist on March 28, 2012
Answer:That would depend on the application. If the coal is simply being burned on a grate in an open fireplace, then there would be no issue as this material is rated to withstand temperatures of 2200 degrees. However, coal being used in a closed combustion chamber furnace is capable of reaching much higher temperatures. As such, we would not recommend the use of this product in that type of installation.

We are adapting a woodburning outdoor prefab fireplace unit to LP gas logs. The unit is steel but I would like to install firebrick to the inside of the box. I am looking for a high heat, outdoor cement or adhesive that will bond with both steel and firebrick. What product would you recommend?
By eFireplaceStore on September 18, 2014
Answer:While we do offer adhesives that can successfully bond masonry to metal, they will not work well for this application. The issue is that the firebrick and metal chassis of the firebox will have very different expansion rates. Past customers that have tried to to this have had issues with the brick cracking and bowing after a relatively short amount of time. Manufacturers of prefab units that use firebrick assemble the brick in panels. This is accomplished by notching each course of brick and using a metal rail to link each course together. After assembly, the gaps are mortared and a metal mounting rail is attached to the upper and lower end, allowing the panel to sit against the inner wall.

I am trying to protect the inside of a steel firebox for my meat smoker. Can I cast a 20x20 inch slab with your product? What, if any, material can I use as reinforcement?
By eFireplaceStore on February 22, 2016
Answer:This product will be perfect for that application, as it has an excellent ability to be cast into various shapes and thicknesses. Expanded mesh wire works well as a reinforcement agent.

What is the recommended outdoor temperature range for using this product to repair an outdoor firepit?
By Collin C. - NFI Master Hearth Professional on November 20, 2013
Answer:This product is tested to continuous temperatures of 2,200 degrees, regardless of an indoor or outdoor application. The product cures hydraulically, meaning that it does not need heat to set to full hardness.

We recently installed a metal fireplace door that has a flange that covers the painted brick just outside the firebox. There are irregular gaps all around the door frame that we would like to fill and paint to match the fireplace. The largest gaps are about 1". Is this Rutland castable refractory fireplace cement the right product or can you recommend a product (or combo of products) that would work for this application?
By eFireplaceStore on November 9, 2015
Answer:This will be the exact product to use. This type of mortar has good adhesion and retains its shape well, enabling it to bridge larger gaps without running or sagging. You will need to keep the consistency a bit dryer when mixing to allow for enough build up to the brick surface. It will also be necessary to remove the paint around the adhesion zone prior to using the mortar.

I have a Vermont Casting wood insert and the brick inside is broken. Can this cement be used to attach the broken back together?
By Will M. on May 3, 2016
When firebrick is broken inside a wood stove or insert, it must be replaced. To locate the proper replacement part, please fill out this form.

Will this Rutland castable refractory fireplace cement bond with cement or be able to adhere to rock?
By eFireplaceStore on November 17, 2015
Answer:It will indeed. This product offers good adhesion properties and when mixed a bit on the dry side, it will retain its shape and hold well to existing vertical cement and stone surfaces.
