REPIKIT EP 310
CARTRIDGE EPOXY ADHESIVE FOR STRUCTURAL INJECTIONS
Low viscosity epoxy system, mixed internally, for injection as structural consolidation and for welding gaps and cracks. The resin and hardener come in a special, ready-to-use cartridge supplied with the accessories needed to carry out pneumatic or manual gun injection.
REPIKIT EP 310 structural adhesive is ready to use: it is supplied as a cartridge with all necessary tools to carry out injections with hand or compressed air gun.
Due to its low viscosity, the product allows to block even narrowest cracks inside walls assuring an high contact surface and therefore an efficient bonding.
After mixing components inside the cartridge, its contents must be fully used.
- The system features internal mixing with pre-weighed resin and hardening agent which are packaged in two separate chambers in a 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 gun with pressure up to 15 atm;
- 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

The system is made of: a cartridge with the product, connecting or injection hose, nipples or nonreturn valve (to be applied on the wall where the chosen injection point is) and a breather pipe.
Preparation of the support
Open the crack or injection point well by removing crumbly parts with an abrasive disc, brush or scraper. Thoroughly clean using a vacuum cleaner or compressed air.
Fix the nipples 20 – 30 cm one from the other, applying epoxy stucco like RESICOL 100 or REPIKIT 315 on the back of the nipple, then press it slightly against the crack or the injection point.
Carefully seal the crack using the same epoxy stucco and by using a small spatula or brush. Let it harden for 4 – 12 hours depending on the temperature.
Preparation of the product
To mix the resin and hardener you have to break the glass ampoule containing the hardener beating the cartridge in the spot indicated on the label, then shake the contents gently back and forth for 2-3 minutes without slamming.
Application
Insert the cartridge in the gun, attach the connecting rod to the nipple in the lowest injection point and fix it well using the threaded ring. Insert a breather pipe in one of the next nipples and then start pumping. When the resin appears in the upper nipple, remove the injection pipe and joint it the same way to the next nipple: continue until complete filling of the crack.
After a few minutes repeat the operation to restore the material absorbed by the support.
When hardening is complete, which takes 1 – 15 hours, remove the nipples and stucco on the surface using a chisel and level out using an abrasive disc.
Notes
Carefully examine the crack or cleft before starting an injection process: REPIKIT 310 is recommended especially for passing cracks in compact building materials (e.g. concrete) when it is possible to know their depth and length to calculate the volume and therefore the quantity of material necessary for complete filling.
We recommend marking the points where injection nipples are going to be glued.
When mixing the reaction between the two components starts: time available is therefore limited and it depends on the temperature.

REPIKIT EP 310 is used to carry out structural strengthening injections in passing and blind cracks not larger than 1 – 2 mm wide on compact materials like concrete, bricks, stone, tuff, wood and more in general for:
- Concrete structural welding of beams, pillars and civilian engineering works;
- Strengthening of damaged concrete, solid brick, rock or stone masonry (in this case by previously filling in voids with fluid cement mortar);
- Fixing of steel and plastic reinforced by fibreglass fixed to wood and concrete connectors and with comb stitch of structural damages;
- Gluing of steel-concrete-wood elements, composite slab connectors with wooden beams, window sills, steps, unglued cement screeds.
