PEP™ is a low viscosity, 100% solids formulation damp-tolerant epoxy resin system intended for priming the surface specifically for use in wet or damp substrates. PEP™ Primer is an easy to use 4:1 volumetric mix, and cures quickly with low odor. PEP™ can be used in different fields like strengthening and retrofitting of structural members as well as concrete repair works..

Key Features

  • Very low viscosity
  • Excellent adhesion to poorly prepared substrates and a wide range of substrates.
  • Good humidity and corrosion resistance
  • Improves substrate chemical resistance
  • Fast cure response
  • Epoxy primer penetrates deeply to eliminate concrete dusting, providing for easy cleanup and minimum maintenance.
  • PEP™ will effectively protect against the intrusion of destructive salts, oils, solvents, and gasoline.
  • Top-graded anti-corrosive primer.


  • Is used in moist surface to interfere with the normal adhesion of epoxy materials to bondable substrates.
  • This material is used as a primer under the carbon wrap systems and laminates.
  • Is used for filling spalls and bug holes.

Storage Conditions

PEP™ must be stored at 5°-35°C and cool place but do not allow to freeze.

Shelf Life

PEP™ can be stored for 2 years in unopened packaging.
