Vetoprime EP491

Epoxy-based primer (Versatile and solvent-free).

Vetoprime EP491 is a two-component, solvent-free, epoxy resin with excellent sealing properties. It can also be a universal primer for the Vetorep and Vetotop systems. When applied on prepared concrete and cementitious substrates, it seals them and enhances their bonding with topcoats. Vetoprime EP491 can be used internally as a stand-alone seal coat to harden cementitious surfaces and prevent dusting.

Uses

  • As a universal versatile primer for resinous flooring and concrete repair systems, especially screeds and self smoothening toppings.
  • As a stand-alone sealer and surface hardener.
  • As a dust proofer for cementitious surfaces.
  • To seal highly porous cementitious substrates.

Advantages

  • Easily applied by brush, roller or spray.
  • Versatile with applications in a large number of coating materials and sealants.
  • Designed for highly porous surfaces.
  • High wetting properties.
  • Perfect for use with epoxy, urethane screeds and self smoothening toppings.
  • Cost effective, suitable for use in MENA region conditions.
  • Suitable for the weather conditions of the MENA region.

Usage Instructions

Vetoprime EP491 must be applied to a sound, clean and dry surface to achieve maximum bond strength between substrate and 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 are present, it is essential to remove all contaminations.

Mix Vetoprime EP491 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 EP491 immediately in a thin continuous film using stiff brushes or rollers. Avoid over-application and puddles. 

Allow Vetoprime EP491 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.
