A: TruGround® Conductive Primer is a patented water based epoxy developed specifically for electronic testing of conventional roofing assemblies. Once applied to a non-conductive substrate, such as wood, insulation or coverboard, the primer enables Electronic Leak Detection testing of the membrane for the life of the roof. TruGround® is required to be placed on the substrate directly below the membrane. Any other conductive mediums placed below the coverboard results in invalid leak detection tests.
