Vetoprime EP391

Two component solvent free epoxy primer.

Vetoprime EP391 is a two-component solvent-free epoxy. It is a specialty industrial primer for the Vetorep and Vetotop product range. It is applied to prepared concrete and cementitious substrates to seal the substrate and enhance bonding with topcoats. The product can be used as a stand-alone product in internal applications as a seal coat to harden cementitious surfaces and prevent dusting. Vetoprime EP391 is designed to be the ideal primer for damp concrete.

Uses

  • As an industrial grade primer for resinous flooring and concrete repair systems.
  • As a primer on damp concrete. 
  • Sealing of highly porous cementitious substrates.

Advantages

  • Easy to apply by brush, roller, or spray.
  • Versatile with applications in a large number of coating materials and sealants.
  • It can be applied to damp concrete.
  • High wetting properties.
  • Damp tolerant.
  • Perfect for use with epoxy, urethane repairs, screeds, and self smoothening toppings.
  • Cost-effective, suitable for use in MENA region conditions.

Usage Instructions

It is essential to apply Vetoprime EP391 to a sound and clean surface to achieve maximum bond strength between the substrate and the coating/repair products.

Concrete substrates should be at least 28 days old, and the relative humidity of the concrete is 75% or below. Remove laitance deposits on new concrete by light grit blasting, mechanical scrabbling, or grinding.

Where heavy contamination by oil and grease occurs or existing coatings present, it is essential to remove all contaminations.

Mix Vetoprime EP391 as supplied. Add the entire content of the hardener container to the base container and mix thoroughly for about 2 minutes. Once mixed, apply the Vetoprime EP391 immediately in a thin continuous film using stiff brushes or rollers. Avoid over-application and puddles.

Allow Vetoprime EP391 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.
