Instructions for use

General Applications

  • Priming of joint edges to receive urethane, epoxy, and polyurea-based sealants.
  • Priming of concrete slabs and walls to receive solvent-free epoxy, urethane, MMA, polyurea, hybrid coatings, screeds, and self smoothening toppings.
  • Priming of concrete substrates to receive epoxy and urethane-based repair mortars.
  • Priming of cementitious screeds to receive epoxy, urethane, and resinous toppings.
  • Priming of steel substrates


Mix Vetoprime EP390 as supplied. Add the entire content of the hardener container to the base container and mix thoroughly for about 2 minutes. Once mixed, apply Vetoprime EP390 in a thin continuous film by using stiff brushes or rollers. Avoid over-application and puddles.
Allow Vetoprime EP390 to become tack-free before applying epoxy coating (unless otherwise specified) but well within the open time specified for the given temperature.
The hotter the substrate, the more quickly the primer will become dry.


Clean all tools and equipment immediately after use with Vetonit Solvent XX400.

Surface Preparation

Surface Preparation

Vetoprime EP390 must be applied to a sound, clean, and dry surface to achieve maximum bond strength between substrate and coating/repair products.

Concrete Substrates

It should be at least 28 days old, and the relative humidity of the concrete is 75% or below. Laitance deposits on new concrete are best removed by light grit blasting, mechanical scrabbling, or grinding.

Where heavy contamination by oil and grease has occurred or existing coatings are present, it is essential to remove contaminations.

Additional Information
