REPIKIT EP 315 is a structural adhesive plaster-like consistency that comes in a cartridge.
Its thixotropic consistency makes sure that the product possesses a low viscosity when subjected to a force kinetics (injection pressure) and high viscosity when it is in a state of rest. The injected material then penetrates with ease in lesions 4 - 10 mm wide and, once the injection pressure, thickens and congeals without dripping and spread further.
After mixing the components, which takes place inside the cartridge, the contents should be completely used.

  • The system features internal mixing with pre-weighed resin and hardening agent which are packaged in two separate chambers in the same cartridge;
  • It ensures high mechanical properties;
  • Excellent adhesion to all building materials with dry or damp bottom;
  • Practical and safe use with hand gun or compressed air and apply with a paint brush or spatula;
  • High work safety and sanitary conditions of the work: the operator never gets in contact with the product;

REPIKIT has been patented and standardized with PATENT no. 86810563.6

Preparation of the support
The substrate must be clean, free of loose particles, dust and cement grout. The most appropriate treatment is sandblasting; if you cannot, you must at least be mill, bushhammer or brush.
The application on metals involves the removal of oil, grease, paint and rust by sandblasting or abrasion to white metal (SA 2 - 3 SA).
In the case of bonding of a cracked element, it is advisable to open the crack as much as possible, possibly by removing the parts to be bonded (this applies in the case of thresholds, steps or removable parts): remove the loose particles with hard abrasive brush or scraper and thoroughly cleaned with a vacuum cleaner or compressed air.

Preparation of the product
To mix the resin with the hardening agent make a hole in the aluminium seal on the head of the cartridge and slowly insert the stirring rod until the stop. Screw the rod clockwise and carefully push it to the bottom of the cartridge. Move the rod backwards and forwards for at least 3-4 minutes until complete blending. Remove the rod by turning it counter-clockwise.
For 450 and 900 mℓ cartridges screw the static mixer on top of the cartridge, insert it in the appropriate injection gun and extrude the product.

Application
Insert the cartridge into the gun and extrude the product on the bonding surface: spread with a spatula or a trowel. Combine the elements to be bonded immediately; the curing time varies from 12 to 24 hours, depending on ambient temperatures. Maintain pressed the items until full cure.

Notes
To apply REPIKIT 315 in hard to reach places, use the special nozzle for injection (length 11 cm) screw-on top of the cartridge in place of the standard one.

When mixing the reaction between the two components starts: time available is therefore limited and it depends on the temperature.

Packages must be kept vertically and closed: the product remains unaltered for at least a year if kept in a place with temperature between 10 and 30 °C.

REPIKIT EP 315 is used to carry out structural strengthening injections in blind cracks 4 - 10 mm wide passing on compact materials like concrete, bricks, stone, tuff, wood and more in general for:

  • Fixing steel and fibreglass plugs and connectors on concrete and wood for comb seam of the structural lesions and in collaborating wood-concrete floor slabs;
  • Gluing and grouting of cracks nipples before performing injections of consolidation with RESISYSTEM 310-312 and REPIKIT 310-312;
  • Consolidation of structural elements with the technique of Beton-Plaquet thanks to the excellent adhesion to steel;
  • Bonding of elements in stone or marble as sills, steps and thresholds to the substrate.
