Black Jack ETERNA-KOTE 100% Silicone Roof Coating is formulated to deliver superior waterproofing protection across many types of roof surfaces. This moisture-cure rubber coating forms a chemical bond to the roof surface, delivering exceptional adhesion and a permanent waterproof seal to almost any type of roof. Black Jack ETERNA-KOTE is a permanent solution on flat roofs and for areas that may pond water. The elastic finish will not crack and will last where other coatings fail. Ideal for hot or cool environments, Black Jack ETERNA-KOTE dries to a bright white finish which reflects UV and keeps roof surfaces cooler to help reduce cooling costs. Additionally, the high solids formula is quick setting, low odor and can be applied in a wide range of temperatures to allow for more application opportunities.Permanent leakproof seal100% silicone rubberProtects, reflects and cools roofsRain safe in 15 minExtended application temperature rangeIdeal for flat roof with ponding water
