﻿Our intense focus on concrete, coupled with a state-of-the-art research and development facility has yielded many concrete industry “firsts” as well as products that are unique to us. Because of our knowledge of concrete chemistry, we are able to innovate at a level not found elsewhere. An important example of this is ChemMasters' acknowledged leadership in the formulation and manufacturing of low-VOC solvent-based products for use in the states that require them. We offer an extensive line of environmentally-friendly, high performance concrete cure and seal products. Our company is family owned and operated, and has been so for over fifty years. During this time, we have proudly expanded the quantity and depth of our product lines, while competing head-to-head with publicly owned conglomerates. We are equally proud of our ability to compete successfully in a distressed construction market, and we attribute this success with “staying true” to the values of our founder.
