TREMprime™ VB Plus Primer

TREMprime VB Plus Primer is a two-component, epoxy-based solvent-free vapor barrier primer for concrete surfaces. It is low odor, non-flammable, and is proven to reduce moisture vapor emissions on concrete slabs. It also resists damage from sustained high alkalinity up to pH 14, and meets or exceeds the requirements of ASTM F3010-13, “Standard Practice for Two-Component Resin-Based Membrane-Forming Moisture Mitigation Systems”.

Product Description

TREMprime® VB Plus Primer is a two-component, solvent-free, epoxy-based vapor barrier primer formulated to mitigate moisture vapor transmission in concrete substrates. Its low-odor, non-flammable composition makes it suitable for occupied spaces, and it meets or exceeds ASTM F3010-13 standards for moisture mitigation systems.

Key Benefits

  • Moisture Mitigation: Effectively reduces moisture vapor emissions on concrete slabs with high moisture levels.
  • High Alkalinity Resistance: Resists damage from sustained high alkalinity up to pH 14.
  • Quick Installation: Fast cure time even in 100% humidity conditions accelerates project timelines.
  • Low Odor & Non-Flammable: Safer for use in occupied buildings and sensitive environments.
  • Chemical Resistance: Provides long-term durability against various chemicals.
