Vertical & Overhead - SikaQuick® VOH LD

FAST SETTING, DUST REDUCED, ONE COMPONENT, CEMENTITIOUS VERTICAL AND OVERHEAD REPAIR MORTAR

SikaQuick® VOH LD is a fast setting, dust reduced, one component, ready-to-use repair mortar for vertical and overhead applications using specialty cement blends.

• Dust reduced mortar
• Minimal time required between lifts
• Fast finishing time
• Time/labor-saving material; application up to 3" (76 mm) on vertical surfaces in one layer
• Easy to use; just add water
• High bond strength ensures excellent adhesion
• High early and ultimate strength
• Increased freeze/thaw durability and resistance to deicing salts
• Suitable for exterior and interior applications.
• Overhead thickness up to 2" (50 mm) per lift
• Fiber reinforced and polymer modified
• Contains corrosion inhibitor
• Rapid hardening as defined by ASTM C 928.
• Use in cold temperatures with SikaQuick Winter Boost [minimum substrate 35^o F (2^o C); minimum ambient 20^o F (- 7^o C) during cure]

Usage

• Fast repairs to overhead and vertical concrete and mortar surfaces on grade, above and below grade.
• As a repair material for building facades, parking structures, industrial plants, bridges, etc.
• As a fast setting repair material for new construction defects.

(Coverage figures do not include allowance for surface profile and porosity, or material waste.)

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 typical published performance property values.

With Sika Latex R

• Start mixing with 6 pints (2.8 L) of SikaLatex®-R per bag.
• Adjust the SikaLatex®-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.

• The mixed 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 of already placed lift to produce a roughened substrate for the next lift.
• Allow preceding lift to harden and achieve Initial Set.
• 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 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 curing should commence immediately after finishing.
• Moist cure with wet burlap, a fine mist of water topped with polyethylene sheeting, or a Sika® Antisol®-250 W*
• Curing compounds adversely affect the adhesion of following lifts of additional mortars or protective coatings.
• 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.
