Rated 4.0 out of 5.0 by Okay Did not score the highest due to product melted when using the fireplace. March 10, 2015
Rated 4.0 out of 5.0 by Fire-barrier The caulk worked fine for application but has not been tested under fire. October 14, 2014
Rated 2.0 out of 5.0 by Not Great It was dry and 'chunky' and very hard to apply. It should have had the viscosity of a good caulk product. September 16, 2014
Rated 5.0 out of 5.0 by Did the job This fire caulking is excellent & always performs as expected August 26, 2014
Rated 5.0 out of 5.0 by best of its field Fire caulk is easy to use, same as caulk, preformed as expected. Product is much easier to use and clean-up is easy with water compared to competitor products. Sticks well to surfaces and edges for overhead installations. August 13, 2014
