Henry 687 100% Acrylic Enviro-White? Extreme Elastomeric roof coating is a premium, high solids white reflective roof coating. It features dirt pick-up resistance (DPR) technology, which prevents dirt and dust build-up, keeping the roof whiter and more reflective longer. When cured, it forms a permeable membrane, which prevents liquid infiltration, but allows moisture vapor to vent or breathe out of underlying substrate.
