Mule-Hide #311 Non-Fibrated Emulsion Roof Coating stands up to heat, rain and snow and is particularly at home in hot climates. The asphalt-based clay emulsion roof coating protects smooth-surfaced asphalt built-up roofs and modified bitumen roofing membranes. It does not flow when applied in thick coats. When dry, it stays firmly in place, even when exposed to elevated temperatures.
