Yes. Cool’s state-of-the-art technology makes an excellent overlayment for knock-down finishes. Knock-down finishes often lose their ability to cool after they’ve been resurfaced, making them a “one-generation” solution in terms of heat abatement. Cool is the only known overlayment for knock-down finishes that continues to keep the surface cool, changing knock-down finishes from a one-generation to a multi-generational solution.
