The Reflecto Seal 1 Gallon Graystone is a professional-grade, heat-reflective coating engineered to keep decorative concrete surfaces cooler and longer-lasting. This water-based, 1-gallon formula uses infrared-reflective pigments to reduce surface temperature while delivering a uniform finish in a timeless, high-quality tone. Ideal for pool decks, patios, and walkways, it protects overlays from UV rays, moisture, and wear, while offering breathability and low VOC content for safe indoor or outdoor use. When paired with the proper primer and optional topcoat, Reflecto Seal creates a durable, comfortable surface that performs as well as it looks.
