This easy-to-use spray-on formula provides long-lasting protection for virtually any concrete/masonry surface including: concrete, brick, masonry, natural stone, artificial stone, pavers, stucco, split-face block and more. This product differs from most waterproofers because of its vapor transmission abilities, which allow for long-term product and substrate performance. This allows substrates to still cure and prevents moisture from being trapped which can lead to a rapid degradation of the substrate. How can EA Concrete & Masonry Waterproofer repel water so effectively and yet manage to remain permeable to water vapor? To use an analogy, it functions like leaves do in nature, leaves hold water at bay allowing it to run off the surface, but they also allow the plant to exchange gases with the environment.
