Technical Information
Product Description

Vetorep ER356 is a three component epoxy based thixotropic solvent free and fast strength development repair mortar. Once components of the kit are mixed the products becomes a high strength abrasion resistant that can be built up to 50 mm in horizontal repairs and vertical repairs in one go. 

Advantages
  • Rapid strength development commissioning in 2 days, full cure in 7 days.
  • Chemically resistant mortar.
  • Superior bond to a wide range of substrates.
  • Compatible with most coating and topping types.
  • Abrasion resistant for heavy duty applications.
  • Structural grade - high ultimate strength.
Compiliance Standard
  • EN 13062:2003
  • EN 1504:2013
  • EN1992:2006

Vetorep ER356 is supplied in 15kg kits, with Yield = 15 Liters / Kit

Shelf Life & Storage

Original sealed kits of Vetorep ER356 has a shelf life of 12 months provided it is stored clear of ground in a dry and shaded temperature controlled place <25ºC.

Application Information
Instructions for use

Priming
Substrates should be primed using Vetoprime EP390. Predominantly vertical and metal substrates should be primed using Vetoprime EP390. In both cases, the primer should be mixed in the proportions supplied, adding the entire contents of the ‘hardener’ tin to the ‘base’ tin. The two components should be thoroughly mixed together for 3 minutes.
The mixed primer should be scrubbed well into the prepared substrate, taking care that all imperfections in the surface are properly coated and avoiding ‘pudding’ in depressions. If the primer is absorbed within 30 minutes, a second coat should be applied before continuing. Vetorep ER356 can be applied as soon as the primer has started to gel but still has surface ‘tack’. This is normally between 30 minutes and 4 hours dependent on the ambient and substrate temperatures. If the primer cures hard, a second application must be made before application of Vetorep ER356. The usable life of the mixed primer is approximately 60 minutes at 20ºC or 30 minutes at 35ºC.

Mixing
Care should be taken to ensure that Vetorep ER356 is thoroughly mixed to produce a fully homogeneous trowellable mortar. Vetorep ER356 must be mixed mechanically. The ‘hardener’ and ‘base’ components must be stirred thoroughly to disperse any settlement before mixing them together. The entire contents of the ‘hardener’ container should then be emptied into the ‘base’ container and thoroughly mixed for 3 minutes, then emptied into a forced action mixer of adequate capacity. Add the aggregate slowly with the mixer running and continue for 2 to 3 minutes until all the components are thoroughly blended. Under no circumstances should part packs be used. A slow speed heavy duty drill fitted with a purpose mixer can be facilitated.

Application
Apply the mixed Vetorep ER356 to the prepared substrate by wood 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 is present, application by gloved hands is an acceptable alternative but, in all cases, the product must be finished to a tight surface with a steel trowel. Vetorep ER356 can be applied in sections up to 100 mm thickness in horizontal locations, up to 70 mm thickness in vertical locations or up to 50 mm in overhead sections in a single application and without the use of formwork. Thicker vertical sections may sometimes be possible dependent on the profile of the substrate and the volume of exposed reinforcing steel but should generally be built up in layers. When larger areas are being rendered, a checkerboard application technique is recommended.

Thickness Build-Up
Additional build-up can be achieved by application of multiple layers. Exposed steel reinforcing bars should be firmly secured to avoid movement during the application process as this will affect mortar compaction, build and bond.
Where thicker sections are required, the surface of the intermediate applications should be reprimed and scratch-keyed to provide a suitable surface for subsequent layers. The application of additional layers should follows between 8 and 24 hours at 20ºC after the first application. This time should be reduced at higher temperature. Re-priming and a further application of Vetorep ER356 may then proceed.
If sagging occurs during application, the Vetorep ER356 should be completely removed and re-applied at a reduced thickness on to the correctly re-primed substrate.

Finishing
Vetorep ER356 is finished by the use of a wood float and closed with a steel trowel. The completed surface should not be overworked.

Surface Preparation

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 laitence by light scabbling or grit-blasting. Saw cut or cut back the extremities of the repair locations to a depth of at least 5 mm to avoid feather-edging and to provide a square edge. Break out the complete repair area to a minimum depth of 5 mm up to the sawn edge.
Oil and grease deposits should be removed by steam cleaning, detergent scrubbing or the use of a proprietary degreaser. The effectiveness of decontamination should then be assessed by a pull-off test.
Expose fully any corroded steel in the repair area and remove all loose scale and corrosion deposits. Steel should be cleaned to a bright conditions paying particular attention to the back of exposed steel bars. Grit-blasting is recommended for this process. If lost area of steel is less than 25% then compensate for the loss, shall the lost steel are be higher than 25% then completely replace the reinforcement steel.

Limitation

Vetorep ER356 should not be used when the temperature is below 12ºC and falling. Do not mix part packs under any circumstances. Vetorep ER356 should not be used in overhead locations – use Vetorep ER356 for this purpose. Vetorep ER356 should not be exposed to moving water during application. Exposure to heavy rainfall prior to final set may result in surface scour. If any doubt arises concerning temperature or substrate condition, consult the local Saveto office.

Additional Information
Health & Sefety

Vetoprime UP310, Vetoprime EP490, Vetoprime EP390, Vetonit Solvent XX400 and Vetorep ER356 should not come into contact with the skin, eyes or be swallowed. When using ensure adequate ventilation and avoid inhalation of vapor. Some people are sensitive to resins, hardeners and solvent. 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 ER356 is non-flammable. Vetoprime EP490, Vetoprime EP390 and Vetonit Solvent XX400 are flammable. Keep away from sources of ignition. No smoking. In the event of fire, extinguish with CO2 or foam. Do not use a water jet.
