TruGround® Conductive Primer

A patented formulation that enables what was, until now, not possible: A truly reliable Electronic Leak Detection (ELD) test for conventional roof assemblies.

TruGround® Conductive Primer provides the required conductivity DIRECTLY below the membrane to ensure valid ELD testing per ASTM Guide D7877-14 and ASTM Practice D8231-19.  TruGround® is sold in 5-gallon pails which will cover approximately 1250sqft each.

There is a lot of confusion and misinformation regarding testing conventional roof assemblies using Electronic Leak Detection. Here is a TECHNICAL NOTE to help clear up the confusion.

Other conductive mediums such as the wire mesh or Vector Mapping Grid (VMG), are often installed incorrectly below the coverboard or insulation.  Coverboard and insulation can not carry an electrical charge, therefore ELD testing will not work as the non conductive substrate blocks the electrical circuit.  Conductive medium placement anywhere other than directly below the membrane results in invalid testing and does not comply with industry standards.

    FEATURES

    • UL Listed & FM Approved
    • Made in the USA
    • Provides the required conductivity per ASTM Guide D7877-14 and ASTM D8231-19 for valid ELD testing on conventional roof assemblies, including black EPDM
    • Compatible with high voltage and low voltage ELD methods
    • Chemically and mechanically compatible with fully-adhered, mechanically attached and torch-down membrane systems
    • Less than 30-minute dry time under normal conditions
    • Retesting can be performed for the life of the membrane, should a breach occur at a later date
    • Non-reflective, flat black to ensure complete coverage
    • Water-based (non-flammable & solvent-free)
    • Low VOC, meets Southern California’s strict emissions control requirements for primers
    • Roll, spray, or pre-apply to cover boards, insulation or wood
    • Easily applied to transitions and details where other conductive mediums cannot be used
    • Each 5 gallon pail covers approximately 1250 square feet on most common roofing coverboards.  Porous substrates such as wood reduces the coverage rate

     

    DIRECTLY BELOW THE MEMBRANE

     

    Approved By

    A conductive substrate is required directly below the membrane for valid Electronic Leak Detection (ELD) testing.  This is the same basic requirement for all ELD testing methods (low voltage and high voltage) found on ASTM Guide D7877 and ASTM Practice D8231.
    Conductive mediums may also be referred to as: Conductive Primer, Grounding Screen, Vector Mapping Grid, VMG, Stainless Steel Grid, SS Grid, SS Mesh, Vector Mapping Mesh, VMM, Vector Mapping Felt, VMF. ConDuct Mesh, Conductive Mesh
