BELOIT, Wis. — New Detec TruGround® Conductive Primer from Mule-Hide Products Co. makes effective electronic leak detection (ELD) of conventional roof assemblies fast and easy, helping ensure that a roofing system is watertight and free of breaches, holes, and seam voids.

The patented water-based, liquid-applied, electronically conductive medium is applied directly to the substrate, using a brush or roller, prior to membrane adhesion. Discontinuities in the membrane can then be found by applying an electrical current to the surface of the membrane. Once applied, the primer allows ELD testing — using low- or high-voltage testing methods — for the life of the roofing system.

Detec TruGround Conductive Primer provides peace of mind that a newly installed roofing system is leak-free, and it can be used for maintenance, warranty and forensic purposes. It is compatible with all single-ply membranes and is listed in more than 10,200 Mule-Hide Products Co. Factory Mutual (FM) RoofNav assemblies. It can be applied to any properly prepared, non-conductive horizontal or vertical surface, including insulation, plywood, wood, lightweight concrete and coverboard. It is suitable for use in fully adhered, mechanically attached, and ballasted roofing systems.

The primer dries quickly — typically in less than 30 minutes — and delivers excellent adhesion. Contractor-friendly, it has low volatile organic compound (VOC) content, is non-flammable and is solvent-free.

Detec TruGround Conductive Primer is available in 5-gallon pails. Each pail covers approximately 1,250 square feet of roof area. More information is available at
