• Do not vibrate.
• Do not add other additives other than the recommended Power Pak.
• For professional use only; not for sale to or use by the general public.
• Make certain the most current versions of product data sheet and SDS are being used; visit usa.sika.com to verify the most current versions
• Proper application is the responsibility of the user. Field visits by Sika personnel are for the purpose of making technical recommendations only and not for supervising or providing quality control on the job site.

Concrete

1. Concrete must be structurally sound and fully cured (28 days).
2. Saw cut the perimeter of the area being repaired into a square with a minimum depth of ½” (13 mm) for horizontal repairs and ¼” (6mm) for vertical and overhead repairs.
3. Refer to current ICRI Guideline no. 310.2R for surface prep requirements to permit proper bond.

Reinforcing Steel

1. Remove all oxidation and scale from the exposed reinforcing steel in accordance with ICRI Technical Guideline No. 310.1R.
2. For additional protection from future corrosion, coat the prepared reinforcing steel with Sikagard® P 8100 AP.

1. Precondition material to 70 °F +- 5°(21 °C +- 3°) before mixing.
2. Add recommended potable water for the intended application to the mixing container for each bag of SikaEmaco® OneMix™. If required, add the correct amount of aggregate to the mixer.
3. Add Power Pak directly to mix water. There is no need to open Power Pak.
4. Add the base powder to the water while continuously mixing with a slow-speed drill and paddle, mortar mixer, or other forced action mixer.
5. Mix for a minimum of 3 minutes until fully homogeneous.

Vertical Application

1. Dampen the surface with potable water; it must be saturated surface-dry (SSD) with no standing water.
2. With a gloved hand, scrub a small quantity of mixed material into the SSD substrate. Thoroughly key in and work the material throughout the cavity to promote bond. Do not apply more of the bond coat than can be covered with mortar before the bond coat dries.
3. Apply material in lifts of ¼–2” (6–51 mm). Avoid featheredging. For optimum mechanical bond between successive lifts, thoroughly score each lift and allow to reach initial set before the next layer is applied. Placement time is 20–30 minutes at 70 °F (21 °C) and 50% relative humidity.
4. Trowel, shave, or shape the material to the desired finish after the initial set.
5. The recommended application range of SikaEmaco® OneMix™ is from 40 to 90 °F  (4 to 32 °C). Follow ACI 305 and 306 for hot or cold weather guidelines.

Form and Pour Application

1. Build forms in accordance with ACI 347R. Keep the unrestrained surface area of the repair to a minimum.
2. Saturate the prepared concrete substrate by filling the prepared formwork with clean water 24 hours before placement.
3. Immediately before the placement of SikaEmaco® OneMix™, completely drain this water and seal the drainage outlets, leaving the substrate saturated surface-dry (SSD) with no ponded water remaining.
4. In jobsite circumstances where the formwork cannot be filled with water to achieve an SSD surface, the prepared concrete substrates must be thoroughly hosed down with clean water to achieve an equal level of saturation. Apply the repair material with sufficient pressure to ensure intimate contact with the substrate.
5. Alternatively, a long open-time bonding agent may be used in place of a saturated substrate. In such a case, place the SikaEmaco® OneMix™ before the bonding agent becomes tack-free.
6. Immediately after mixing, pump or pour the SikaEmaco® OneMix™ into the formed area. The material does not require vibrating.
7. The recommended temperature range for application of SikaEmaco® OneMix™ is 40 to 90 °F (4 to 32 °C). Follow ACI 305 and 306 for hot or cold weather guidelines.
   
    

Screed Application

1. Dampen the surface with potable water; it must be saturated surface-dry (SSD) with no standing water.
2. After removing all standing water, thoroughly scrub a thin layer of bond coat into the saturated surface with a stiff-bristled broom or brush. Do not dilute the bond coat with water. Do not apply more bond coat than can be covered with mortar before the bond coat dries. Do not retemper the bond coat.
3. Immediately place the repair mortar from one side of the prepared area to the other. Work the material firmly into the bottom and sides of the patch to ensure good bond. Level the SikaEmaco® OneMix™ and screed it to the elevation of the existing concrete. Apply the appropriate finish.
4. Finish the completed repair, as required, taking care not to overwork the surface.
5. The recommended application range of SikaEmaco® OneMix™ is from 40 to 90 °F  (4 to 32 °C). Follow ACI 305 and 306 for hot or cold weather.
6. A maximum of 15 minutes should be allowed to mix, place and finish SikaEmaco® OneMix™ at 70 °F (21 °C). 

Aggregate Extension

1. For repair areas 2–6” (51–150 mm) in depth, the minimum recommended addition is 15–25 lbs. (6.8–11.4 kg) of ⅜” (9 mm) washed, graded, rounded, SSD, low absorption, highdensity aggregate per 50 lbs. (22.6 kgs) bag.
2. For areas greater than 6” (150 mm) in depth, the recommended addition is 25 lbs. (11.4 kgs) of ⅜” (9 mm) washed, graded, rounded, SSD, low absorption, high-density aggregate per 50 lbs. (22.69 kgs) bag.
3. Aggregate must comply with the requirements of ASTM C 33.

1. Leave the formwork in place until the compressive strength reaches 2,500 psi  (17.2 MPa) or a strength specified by the engineer.
2. Cure with an approved curing compound compliant with ASTM C 309 or preferably ASTM C 1315. If the repair area will receive a coating, wet curing is recommended.

Clean tools and equipment with clean water immediately after use. Cured material must be removed mechanically.
