ProGuard Super Coat’s (Liquid EPDM) main benefit (sprayed or rolled over any existing roofing material) is that there are NO SEAMS! The only weak point to a rolled EPDM is the seamed areas. Super Coat Liquid EPDM eliminates this major weakness. ProGuard’s Super Coat (Liquid EPDM) is the same chemical composition as Rolled EPDM which makes it far superior in both durability, weatherability and as a true water proof membrane compared to all other types of roof coatings and rolled membranes.

Where did this come from? 

Through the advanced chemistry possible in liquid form, EPDM could be UV enhanced, made more temperature tolerant (-40F to 400F), and made resistant to oils and grease (an important factor for restaurant applications and not a benefit of rolled EPDM). ProGuard’s Super Coat Liquid EPDM is extremely cost effective compared to all other forms of roofing materials.

Professional EPDM Supercoat F9951

Professional EPDM SupercoatTM is a catalyzed liquid applied EPDM Rubber Coating that cures at ambient temperatures above 50°F. The coating can achieve dry films up to 40 mils in a one coat application. The physical properties of Professional EPDM SupercoatTM have been optimized for cure, adhesion to many substrates, tensile strength and surface properties including solar reflectance.

Professional EPDM Supercoat is the culmination of over 20 years of Liquid EPDM Coating development. Recent breakthroughs in raw material development have greatly enhanced the attributes of this coating.
