Product Description

Vetorep ER357 is a three-component system consisting of solvent-free epoxy resins and a special blend of fillers to provide a trowel-grade epoxy mortar. The mixed mortar can be used for horizontal and vertical applications. The chemical resistance properties make Vetorep ER357 suitable for application as the lining to sewerage manholes; the product can also be used to repair stair treads.

  • Rapid strength development commissioning in 2 days, full cure in 7 days.
  • Chemically resistant mortar.
  • Excellent bond to concrete.
  • High impact and abrasion resistance.
  • Cures in damp conditions.
  • Provides a waterproof lining to manholes.
  • Cost-effective.
  • Used over Vetoproof CR747 to provide a permanent solution to water leaks.

Application Information
Instructions for use


Stire the hardener and base components thoroughly to disperse any settlement before mixing them together. Empty the entire contents of both components into a clean container and mix thoroughly for 2 minutes using a heavy-duty, slow speed drill fitted with a spiral mixing paddle. Once achieving a uniform color and consistency, slowly add the aggregate, continue mixing until all the components are thoroughly blended.


Apply the mixed Vetorep ER357 to the prepared substrate using a trowel. To avoid sagging on vertical and overhead surfaces, do not apply the mortar greater than 12mm per layer. If greater builds are required, do not close the first layer's surface, apply Vetoprime EP490 after a minimum waiting time of 18 hours, and then apply the second layer whilst the primer is still tacky.


Remove Vetorep ER357 from tools, equipment, and mixers with Vetonit Solvent XX400 immediately after use.


Surface Preparation

Surfaces should be clean and structurally sound. Remove any loose or unsound brick or concrete. Surfaces must be entirely free of oil, grease, paint, detergents, rust, or other contaminants. The surface should preferably be abraded by light sandblasting followed by thorough rinsing to remove dust.

Where a rough surface is difficult to obtain, Vetoprime EP490 should be used to prime the surface. Vetorep ER357 should be applied while the primer is still tacky.


Design Criteria

Vetorep ER357 shall be applied in a checkerboard fashion, at a minimum thickness of 3mm. The use of Vetorep ER357 in a single layer shall conform to:

  • Vertical application up to 12mm.
  • Horizontal concrete repair up to 75mm.


Vetorep ER357 should not be used when the temperature is below 5ºC and falling.

Do not mix part packs under any circumstances.

Do not thin the components with solvent as this will prevent proper cure.

Do not expose the product to moving water during curing.
