Pot Life

 ~ 30 minutes

As the temperature will affect the pot life, application temperature:

  • Above 73 °F (23 °C) will reduce the pot life and slump

  • Below 73 °F (23 °C) will extend the pot life and slump

Finishing Time

~50–120 minutes

Application steps

MIXING

  • With water: Start with 3/4 gal. (2.8 L) of water added to the mixing vessel. Add 1 bag of SikaRepair®-222 while continuing to mix with a low-speed drill (400-600 rpm) and mixing paddle or in an appropriate mortar mixer. Add up to another 1/8 gal (0.5 L) of water to achieve desired consistency. Do not over-water.

   

  • With SikaLatex® R: Pour 3/4 gal. (2.8 L)  of SikaLatex® R into the mixing container. Slowly add powder, mix and adjust as above.

    

  • With diluted SikaLatex® R: SikaLatex® R may be diluted up to 5:1 (water: SikaLatex® R) for projects requiring minimal polymer modification. Pour 3/4 gal. (2.8 L) of the mixture into the mixing container. Slowly add powder, mix and adjust as above.

  

 

Extension with aggregates:

  • For applications greater than 1" (25 mm) in depth, add 3/8" (9.5 mm) coarse aggregate.
  • The aggregate must be non-reactive (reference ASTM C-1260, C-227 and C-289), clean, well graded, SSD, have low absorption and high density, and comply with ASTM C-33 size number 8 per Table 2.
  • Variances in aggregate may result in different strengths.
  • The addition rate is 32 lb. (14.5 kg) of aggregate per bag. It is approximately 2.5-3 gal. (9.5-11.3 L) by loose volume of aggregate.
  • Water may be varied to achieve the desired consistency. Do not over water.

APPLICATION

  • The prepared mortar must be scrubbed into the substrate, filling all pores and voids. Force material against edge of repair, working toward center.
  • After filling repair, consolidate, then screed.
  • Allow mortar to set to desired stiffness, then finish.
  • Mixing, placing and finishing should not exceed 45 minutes.

CURING TREATMENT

  • As per ACI recommendations for Portland cement concrete, curing is required.
  • Moist cure with wet burlap and polyethylene, a fine mist of water or a water based* compatible curing compound.
  • Curing compounds adversely affect the adhesion of following lifts of mortar, leveling mortar or protective coatings.
  • Moist curing should commence immediately after finishing. Protect freshly applied mortar from direct sunlight, wind, rain and frost.


* Pretesting of curing compound is recommended.
