▪ Full depth repairs.
▪ On grade, above, and below grade on concrete.
▪ On horizontal, vertical and overhead surfaces. As a structural repair material for parking facilities, industrial plants, walkways, bridges,tunnels, dams and balconies.
▪ Filler for voids and cavities.

SURFACE PREPARATION:
Surface must be clean and sound. Remove all deteriorated concrete, dirt, oil, grease, and other bondinhibiting materials from the area to be repaired.
▪Preparation work should be done by high pressure water blast, scabbler or other appropriate mechanical means to obtain an exposed aggregate surface profile of ±1/8″ (3 mm) (CSP-7).
▪ To ensure optimum repair results, the effectiveness of decontamination and preparation should be assessed by a pull-off test.
▪ Substrate should be Saturated Surface Dry (SSD) with clean water prior to application. No standing water should remain during application.

PRIMING:

Reinforcing steel: Steel reinforcement should be thoroughly prepared by mechanical cleaning to remove all traces of rust. Where corrosion has occurred due to the presence of chlorides, the steel should be high pressure washed with clean water after mechanical cleaning. For priming of reinforcing steel use Sika® Armatec® 110 EpoCem (consult PDS).

Concrete Substrate: Prime the prepared substrate with a brush or sprayed applied coat of Sika® Armatec® 110
EpoCem (consult PDS). Alternately, a scrub coat of Sikacrete®-100 CI can be applied prior to placement of the mortar. The repair mortar has to be applied into the wet scrub coat before it dries.

MIXING:
▪ Place 4/5 gallon (3 L) water in mixing container.
▪ Add Sikacrete®-100 CI while continuing to mix.
▪ Add additional 1/5 gallon (0.76 L) if needed.
▪ Mix to a uniform consistency, maximum 3 minutes. Mechanically mix with a low-speed drill (400–600 rpm) and paddle or in appropriate size mortar mixer or concrete mixer.

APPLICATION:
▪ Pre-wet surface to SSD. Ensure good intimate contact with the substrate is achieved. To accomplish this, material should be scrubbed into the substrate or other suitable means should be employed such as vibration of the material
or pumping under pressure.
▪ Vibrate form while pouring or pumping.
▪ Pump with a variable pressure pump. Continue pumping until a 3 to 5 psi increase in normal line pressure is evident then STOP pumping.
▪ Form should not deflect. Vent to be capped when steady flow is evident, and forms stripped when appropriate.
