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

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 prior to the application of 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.

Cleaning

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

Surface Preparation

It is essential to apply Vetoprime EP391 to a sound and clean surface in order to achieve maximum bond strength between the substrate and the 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 present, it is essential to remove all contaminations.

Limitation

At temperatures below 20ºC, the cure rate will be slower. Conversely, at temperatures above 20ºC, the cure rate will be faster.

Additional Information
