Limestone Veneer from Mason's Mark Stone Veneer. 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.
