Concrete ‘Cool Deck’ Coatings: Heat Reduction Claims and What Prep Actually Controls Delamination

Introduction Cool deck coatings are heat-reflective surface finishes applied to concrete to reduce surface temperatures and glare. But whether they last depends mainly on how the base concrete is prepared and bonded. This article cuts through the hype and tells you what prep actually controls delamination. Delamination happens when the coating separates from the concrete
