Traditionally, thick elastomeric coatings were not permeable and were mainly used on roofs. Modern elastomeric coatings “breathe,” which lets moisture vapor escape. Rhino Shield’s ceramic elastomeric formula passes wind-driven rain tests and is still fully permeable, allowing the substrate to breathe.
AmCoat’s Director of Products and Applications, Mike Moore, stressed the importance permeability in today’s coatings. “The resin technology we employ allows for a thick, protective elastomeric coating that is fully permeable,” said Moore. “This is super important for wood and stucco. The coating must release moisture vapors to be able to prevent moisture retention which can lead to bubbling and peeling.”
