0.0 (0)
SikaTop®-111 Plus is a two-component, polymer-modified, Portland cement-based, fast-setting, screed mortar. It is a high performance repair mortar for horizontal, vertical and overhead surfaces in form and pour applications. It offers the additional benefit of Sika FerroGard®-901, a penetrating corrosion inhibitor included in its formulation.
- Extremely low shrinkage proven by four industry standard test methods
- High compressive and flexural strengths
- Increased freeze/thaw durability and resistance to deicing salts
- Increased density - improved carbon dioxide resistance (carbonation) without adversely affecting water vapor transmission (not a vapor barrier)
- Enhanced with Sika FerroGard®-901, a penetrating corrosion inhibitor - reduces corrosion even in the adjacent concrete
Usage
- On grade, above grade, and below grade concrete
- Horizontal surfaces (e.g. for spall repairs on flat work, or as an overlay): pour and screed
- Vertical and overhead surface repairs when formed and poured, or formed and pumped with an appropriate pump
- Structural repair material for water and wastewater treatment plants, parking facilities, industrial plants, walkways, bridges, tunnels, dams, abutments, floors and balconies
- Approved for repairs over cathodic protection systems
- Free flowing repair mortar for hard-to-reach areas
- Filler for voids and cavities
- Repair of substrates such as concrete, mortar, and masonry

MIXING
- Pour approximately 7 pints (3.3 liters) of SikaTop® 'A' (liquid) into a suitably sized mixing container.
- Add entire bag's contents of SikaTop®-111 Plus 'B' Component (powder) to the container while mixing continuously with a low speed drill (400–600 rpm) and mixing paddle or mortar mixer.
- Add up to an additional maximum 1 pint (0.5 liter) of SikaTop® 'A' if needed for the desired consistency.
- Mix to a uniform consistency, maximum 3 minutes. Thorough mixing and proper proportioning of the two components is necessary.
EXTENSION WITH AGGREGATES
- Pour all of SikaTop® 'A' Component (liquid) into a suitably sized mixing container or concrete mixer.
- Add entire bag's contents of SikaTop®-111 Plus 'B' Component (powder) to the container while mixing continuously, then introduce 3/8 inch (10 mm) coarse aggregate at desired quantity.
- Mix to uniform consistency, maximum 3 minutes. Thorough mixing and proper proportioning of all components is necessary.
- The aggregate must be non-reactive (reference ASTM C 1260, ASTM C 227 and ASTM C 289), clean, well graded, saturated surface dry (SSD), have low absorption, high density, and comply with ASTM C 33, size number 8 per Table 2.
- Variances in aggregate quality may result in different strengths and performance.
- The typical addition rate is 42 lbs (19 kg) of aggregate per mix. This is approximately 3.0 - 3.5 gallons (11.3 - 13.2 liters) of aggregate by loose volume.
APPLICATION
- Ensure substrate is properly prepared and saturated surface dry (SSD) before application.
- Ensure good intimate contact with the substrate is achieved either through a bonding agent or a scrub coat application, or other suitable means such as vibration of the material or pumping under pressure.
Horizontal Installations:
- After filling repair area, screed the material.
- Allow SikaTop®-111 Plus to set to desired stiffness, then finish with wood or sponge float for a smooth surface or broom or burlap-drag for a rough finish.
- If a smoother finish is desired, a magnesium float should be used.
- To assist in the finishing process, use SikaFilm® finishing aid. Consult current Product Data Sheet.
Form and Pour / Pump Installations:
- Vibrate form while pouring or pumping.
- Pump Extended mixes with a variable pressure concrete pump.
- Continue pumping until a 3 to 5 psi (20 - 34 Pa) 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 to be stripped when appropriate.
- Begin and finish multiple lift repairs on the same day.
- Refer to ACI 305 the "Guide to Hot Weather Concreting" or ACI 306 the "Guide to Cold Weather Concreting" when there is a need to place this product while either hot or cold temperatures prevail. Thinner placements will be more sensitive to the temperature conditions.
CURING TREATMENT
- As per ACI recommendations for Portland-cement concrete, curing is required.
- Moist curing should commence immediately after finishing.
- Moist cure with wet burlap and polyethylene, a fine mist of water or a water-based, compatible* curing compound meeting ASTM C 309.
- Curing compounds adversely affect the adhesion of following layers of mortar, leveling mortar or protective coatings.
- Protect newly applied material from direct sunlight, wind, rain and frost.
- To prevent from freezing, cover with insulating material (e.g. curing blanket).
*Pretesting of curing compound for compatibility is recommended.
