SikaTop®-111 Plus

Two-component, polymer-modified, cementitious, screed mortar plus Sika FerroGard®-901 penetrating corrosion inhibitor

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

Application steps

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.
