Mason's Mark stone veneers are manufactured using only the finest Portland cements, iron oxide pigments and lightweight aggregates. We strive to make every stone strong and durable to provide you with decades of beautiful stone veneer that is virtually maintenance free. For this reason we refuse to add any fillers to our cement mixtures, such as sand, as do many other stone manufacturers, which weakens the final product. We color our stone veneers with only the finest iron oxide pigments and our colors are absorbed into the cement to provide a deep, vibrant end color that should never fade or bleed even after years of weathering. Our lightweight aggregates are mined regionally and provide our stone veneers the ability to be installed without the use of a brick ledge, lintel or any other supporting structure. Weighing in at only 7 to 10 lbs. per square foot this key fact dramatically reduces the historically high cost of installation.
