Description: Durabond® Extreme Primer™ is a single-component, water-based, primer formulated to dramatically improve the adhesion of Durabond cement patches and self-leveling underlayments to Durabond D-261™ Extreme Moisture Vapor Barrier Coating or Durabond D-250™ Moisture Vapor Barrier Coating. This non-flammable, non-corrosive, formulation is to be used ON TOP OF the surface of either D-261 or D-250 and has no application window in which cementitious patches or self-leveling underlayments must be applied to achieve a strong bond. It is pigmented white for visual indication of coverage and film thickness during the application process and is extremely durable and wear resistant. Please refer to and follow industry standards for flooring material being installed (i.e..: NWFA, NOFMA, MMFA, TCA, NTCA, CRI, etc.) prior to using this material. Various flooring materials have vastly different substrate preparation and installation requirements; substrate preparation and installation requirements are key to a successful installation regardless of flooring material being installed.Information provided by Bostik |
