This is a custom built one of a kind fireplace with an extremely powerful BTU rating. The builder asked us for some advice on this fireplace as it would run too hot for most marble tiles they wanted to use. We designed and made our own custom heat resistant plaster to help create a finish that could stand up to the heat but also look beautiful. The entire fireplace was sealed with a special concrete sealer and the striations were made using a special travertine trowel. The color of this fireplace is Kendall Charcoal and matches their house and décor very well.
