Within the floor coating industry, so called “breathable” epoxy is being touted as a new fix for concrete moisture issues. With so much conversation on this topic, it pays to take a closer look. These “breathable” epoxy coatings are permeable, meaning they offer the advantage of allowing moisture to pass through them. While these types of coatings may indeed be appropriate for some facilities, they are not well-suited for all.
Permeable coatings were developed with moisture in mind, to help avoid the risk of surface blistering or other damage due to moisture in the concrete slab or subsurface. However, with such a wide variety of liquid-applied floor coating options—each with their own set of unique advantages or properties—understanding your choices is crucial to ensuring the coating can withstand the demands of its environment. In addition, when selecting a floor coating system, it is important that you understand the difference between hype and reality when it comes to the concept of “breathable” coatings.
