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.

Concrete Substrates

Should be at least 28 days old and relative humidity of the concrete is 75% or below. Laitence deposits on new concrete are best removed by light grit blasting, mechanical scabbling or grinding. Where heavy contamination by oil and grease has occurred or existing coatings are present, it is essential that all contaminations are removed.


Mix Vetoprime EP491 as supplied. Add the entire content of hardener can to the base can and mix thoroughly for about 2 minutes. Once mixed, the Vetoprime EP491 shall be immediately applied in a thin continuous film using stiff brushes or rollers. Avoid over-application and puddles. Vetoprime EP491 shall be allowed to become tackfree 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.


All tools and equipment shall be cleaned immediately after use with Vetonit Solvent XX400.

Surface Preparation

It is essential that Vetoprime EP491 is applied to a sound, clean and dry surface in order to achieve maximum bond strength between substrate and coating/repair products.
