Instructions for use


Mix Vetoprime EP691 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 EP691 immediately in a thin continuous film using stiff brushes or rollers. Avoid over-application and puddles.

Allow Vetoprime EP691 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 XX600.

Surface Preparation

Surface Preparation

Vetoprime EP691 must be applied to a sound, clean and dry surface to achieve maximum bond strength between substrate and coating/repair products.

Concrete Substrates

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.
