Application Information
Instructions for use

Design Criteria

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

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


The ‘hardener’ and ‘base’ components should be stirred thoroughly to disperse any settlement before mixing them together. The entire contents of both components should be emptied into a clean container and mixed thoroughly for 2 minutes using a heavy duty, slow speed drill fitted with a spiral mixing paddle. Once a uniform color and consistency is achieved, slowly add the aggregate, continuing to mix until all the components are thoroughly blended.


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


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


Surface Preparation

Surfaces should be clean and structurally sound. Any loose or unsound brick or concrete should be removed. Surfaces must be entirely free of oil, grease, paint, detergents rust or other contaminants. The surface should preferably be abraded by light sand blasting 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.


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 components with solvent as this will prevent proper cure.

The products should not be exposed to moving water during curing.
