High strength, abrasion-resistant epoxy-based repair mortar
Vetorep ER355 is a three-component epoxy-based thixotropic solvent-free and fast strength development repair mortar. Once mixing the kit components, the product becomes a high-strength abrasion-resistant built up to 50mm in horizontal repairs in one go. Shall higher build-up of thickness in a single vertical application be required, the use of Vetorep ER356 shall be considered.

Vetorep ER355 is supplied in 15 Liters kits. Yield: 15 Liters/Kit, Coverage: 1m2@ 15mm thickness.
Vetoprime EP491 is supplied in 4 Liters Kits. Coverage: 7-12 m2/ Liter.
Vetonit Solvent XX400 is supplied in 4 Liters Cans. Coverage: 4 Liters/can.
Stated coverage values are theoretical and may change depending on various factors such as the nature of substrate and wastage factors.
The original sealed kit of Vetorep ER355 has a shelf life of 12 months, provided it is stored clear of ground in a dry and shaded temperature-controlled place less than 35ºC.
Ensure of taking care to thoroughly mix Vetorep ER355 to produce a fully homogeneous trowel-able mortar. Mix Vetorep ER355 mechanically. Stir the 'hardener' and 'base' components separately to disperse any settlement before mixing them together. Pour The entire contents of the 'hardener' container into the 'base container and thoroughly mix for 3 minutes, then empty the mixture into a forced action mixer of adequate capacity. Add the aggregate slowly with the mixer and continue mixing for 4 to 5 minutes until thoroughly blending all the components. Under no circumstances should part packs be used. If needed, facilitate a slow-speed heavy-duty drill fitted with a purpose mixer.
Apply the mixed Vetorep ER355 to the prepared substrate by trowel float, pressing firmly into place to ensure positive adhesion and full compaction. Thoroughly compact the mortar around any exposed reinforcement. In restricted locations or where exposed reinforcing steel appears, application by gloved hands is an acceptable alternative. In all cases, finish the product to a tight surface with a steel trowel. Vetorep ER355 can be applied in sections up to 50mm thickness in horizontal locations in a single application and without formwork.
The application of multiple layers can achieve additional build-up. Firmly secure exposed steel reinforcing bars to avoid movement during the application process as this will affect mortar compaction, build, and bond.
Where thicker sections are required, the intermediate applications' surface should be scratch-keyed to provide a suitable surface for subsequent layers. The application of additional layers should follow between 8 and 24 hours at 20ºC after the first application. Reduce this time at a higher temperature. Re-priming and a further application of Vetorep ER355 then may proceed.
If sagging occurs during application, the Vetorep ER355 should be completely removed and re-applied at a reduced thickness onto the correctly re-primed substrate.
Finish Vetorep ER355 by the use of a wood float and closed with a steel trowel. Do not overwork the completed surface.
High temperature working
At ambient temperatures above 35ºC, Vetoprime EP491 and Vetorep ER355 will have shorter pot lives and working lives. Store the materials in the shade or an air-conditioned environment, and do not apply in direct sunlight.
Curing protection is not necessary for Vetorep ER355.
Over-coating with protective/decorative finishes, Vetorep ER355 is extremely durable and resistant to a wide range of acids, alkalis, and industrial chemicals. It will provide excellent protection to the concrete and embedded steel reinforcement within the repaired locations. The surrounding parts of the structure may benefit from applying a protective coating, thus bringing them up to the same protective standard as the repair itself. Saveto recommends the use of a Vetotop range of epoxy resin, chemical-resistant, protective coatings.
For the surrounding areas not subjected to chemical attack or physical wear, Saveto recommends using the Vetotop range of anti-carbonation, anti-chloride protective coatings. These products provide a decorative and uniform appearance and protect areas of the structure that might otherwise be at risk from the environment.
Apply Vetotop epoxy resin protective coatings within 24 hours. Do not apply non-epoxy or urethane Vetotop products until the Vetorep ER355 is at least 3 days old. For further advice, consult the local Saveto office.
Remove Vetoprime EP491 from tools, equipment, and mixers with Vetonit Solvent XX400 immediately after use.
Clean the surface and remove any dust, unsound or contaminated material, plaster, oil, paint, grease, corrosion deposits, or algae.
Roughen the surface and remove any laitance by light scabbling or grit-blasting. Saw cut or cut back the repair locations' extremities to a depth of at least 5mm to avoid feather-edging and provide a square edge. Break out the complete repair area to a minimum depth of 5mm up to the sawn edge.
Remove oil and grease deposits by steam cleaning, detergent scrubbing, or the use of a proprietary degreaser. A pull-off test should then assess the effectiveness of decontamination.
Expose fully any corroded steel in the repair area and remove all loose scale and corrosion deposits—clean steel to a bright condition paying particular attention to the back of exposed steel bars. Grit-blasting is recommended for this process. If the lost area of steel is less than 25%, then compensate for the loss. Shall the lost steel is higher than 25%, then completely replace the reinforcement steel.
Prime the horizontal substrates by using Vetoprime EP491. Mix the primer in the proportions supplied, adding the entire contents of the 'hardener' tin to the 'base' tin. Mix the two components thoroughly together for 3 minutes.
Scrub the mixed primer well into the prepared substrate, coat all imperfections on the surface properly, and avoid 'pudding' in depressions. If the substrate absorbed the primer within 30 minutes, apply a second coat before continuing. Apply Vetorep ER355 as soon as the primer starts to gel but still has surface 'tack,' this is normally between 30 minutes and 2 hours, dependent on the ambient and substrate temperatures. If the primer cures hard, apply another coat before the application of Vetorep ER355. The usable life of the mixed primer is approximately 60 minutes at 20ºC or 30 minutes at 35ºC.
Vetorep ER355 shall be applied in a checkerboard fashion, at a minimum thickness of 5 mm. The use of Vetorep ER355 in a single layer shall conform to:
Vetoprime EP491, Vetonit Solvent XX400, and Vetorep ER355 should not contact the skin, eyes, or swallow. When using, ensure adequate ventilation and avoid inhalation of vapor. Some people are sensitive to resins, gardeners, and solvents. Wear suitable protective clothing, gloves, and eye protection. The use of barrier creams provides additional skin protection. In case of contact with eyes, rinse immediately with plenty of clean water and seek medical attention immediately. If swallowed, seek medical attention immediately. Do not induce vomiting.
Vetorep ER355 and Vetoprime EP491 are non-flammable. Vetonit Solvent XX400 is flammable. Keep away from sources of ignition. No smoking. In the event of a fire, extinguish with CO2 or foam. Do not use a water jet.
