Clear Guard H2O is a water-based, VOC-compliant, nonyellowing material that can be applied over newly placed or existing concrete. It enhances colored concrete, protects surfaces from dirt and stains, diminishes the effects of deicing salts, and minimizes the exposure to gas and oil. The product provides a high-gloss finish and often is used for interim protection during construction. Butterfield Color. 800-282-3388.
