Application Steps

• Wet down all tools and mixer to be used.
• Mix mechanically with a low-speed drill (400-600 rpm) and mixing paddle or mortar mixer.
• Mix to a uniform consistency, maximum 3 minutes.
• Manual mixing can be tolerated only for less than a full unit.
• Thorough mixing and proper proportioning of the powder and liquid is necessary.
• Inaccurate proportioning of the powder to liquid will result in a finished product that may not conform to the typical published performance property values.

With water

• Start mixing with 6 pints (2.8 L) of water per bag.
• Adjust the water dosage by a maximum amount of +/- 1/2 pint, if necessary, to achieve the desired consistency.
• Do not over-water. Over-watering may result in difficulty handling and/or not meeting stated property values.

With Sika Latex R

• Start mixing with 6 pints (2.8 L) of Sika Latex® R per bag.
• Adjust the Sika Latex® R dosage by a maximum amount of +/- 1/2 pint, if necessary, to achieve the desired consistency.
• Do not overdose with SikaLatex® R. Using too much SikaLatex®-R may result in difficulty handling and/or not meeting typical published performance property values.

With SikaQuick® Winter Boost

• Pour the recommended volume of clean, potable water [> 34° F (- 1° C)] into a suitably sized and clean mixing container.

• Add 1/2 or 1 cup per bag into the water and mix until it is dissolved.

• Add the contents of the SikaQuick® VOH / SikaQuick® VOH LD bag while continuing to mix.

• Refer to the current Product Data Sheet for complete and detailed instructions on the use of the SikaQuick® Winter Boost.

• The mixed SikaQuick® VOH / SikaQuick® VOH LD must be worked well into the prepared substrate, filling all pores and voids.
• Compact well. Force material against edge of repair working towards the center. Thoroughly compact the mortar around exposed reinforcement.
• After filling repair, consolidate, then screed.
• Finish with steel, magnesium, wood, plastic floats, or damp sponges, depending on the desired surface texture.

MULTIPLE LIFTS

• Where multiple lifts are required, score top surface on each lift to produce a roughened substrate for next lift.
• Allow preceding lift to harden and achieve initial set before applying fresh material.
• SSD previous lift by lightly misting with clean water. Remove all standing droplets.
• Repeat procedure until desired installation thickness is achieved. Finish the final lift of SikaQuick® VOH / SikaQuick® VOH LD as described above.
• If previous layers are over 6 hours old, mechanically prepare the substrate and dampen.

• As per ACI recommendations for Portland cement concrete, curing is required.
• Moist cure with wet burlap and polyethylene, a fine mist of water or Sika® Antisol®-250 W*.
• 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.

• Uncured product may be cleaned from tools and surfaces with water.
• Cured product must be removed mechanically.
