Ahrens Chamber-Tech 2000 Smoke Chamber Parging Mix is a truly remarkable masonry compound. In addition to insulating masonry and reducing heat conduction to combustible materials, this parging mix can also be used to satisfy the NFPA 211 requirement for smooth smoke chambers. You can even use Chamber-Tech 2000 with a lintel angle kit and expansion tape to create a UL Listed smoke chamber. And, of course, you shouldn't forget that an application of this structural compound improves a smoke chamber's ability to resist creosote build-up and makes it much easier to clean. For optimal immediate and long-term results, Chamber-Tech 2000 Smoke Chamber Parging Mix is definitely your best option.

Can the Chamber Tech 2000 mix be used on top of a steel firebox? The top of my firebox opening is rotted and I was told by a chimney cleaner that I could use this product over the rotted metal. Is this true?

I have not come across a manufacturer of prefabricated fireplaces that would allow such a repair. The reason is because of the change in heat transfer properties and flow of flue gases that could occur. Having the parging mix mounded over the metal could cause heat buildup in that spot, leading to a change in safe clearances to combustibles on the top side of the unit. The irregular mass could also cause partial obstruction of the flue gases, leading to the occasional pack puff of smoke. Also, depending on if the unit itself is supporting the chimney and how bad the corrosion is, the weight of the chimney could eventually cause the metal to completely tear. While it is certainly the more costly route, I recommend having the unit replaced.

How do you parge the smoke chamber?
By Kevin E. - NFI Certified Specialist on August 26, 2013
Parge coating is basically the application of a relatively thin coat of mortar to a masonry surface - similar to a skim coat. This product applies easily with a trowel or by hand. However, gaining access to the smoke chamber can sometimes be difficult. The easiest method is to remove the damper plate and associated controls. This item page has a downloadable product manual that will provide additional information.

I'm looking for a product to apply a refractory coat to the base of a metal fireplace. The trade name for the original coating was malmcrete.

Removed damper for easier access to smoke box. Dry mix before adding water, fibers seemed to settle in bottom of pail. Mixed as directed, install went smoothly, adhered very well to brick, cured hard. Used 3.5 - 30lb pails to coat entire smoke box. Delivery was super fast, came second day after order.
