Test Data
Results provided by licensed engineering test laboratory and represent typical results from production materials. Actual results may vary from third party testing results; however, CERATECH’s materials meet and/or exceed established internal quality control standards, (available upon request) . All samples were air cured.

1 - 3rd party test results
2 - Internal test results
TBD - To be determined
NTBT - Not to be tested



Site Preparation
Surfaces should be prepared in accordance with ICRI 03730, “Guide for Surface Preparation for the Repair of Deteriorated Concrete Resulting from Reinforcing Steel Corrosion.” and / or ACI 546R-96 “Concrete Repair Guide”. Concrete surface should be prepared by appropriate mechanical methods to obtain an exposed aggregate surface with a minimum surface profile of +/- 1/16” (1.5 mm) in accordance with ICRI 03732. Pre-existing coatings or surface treatments should be completely removed. Dry, clean, stable surfaces are required. Remove all standing water. Reinforcing steel should have no loose scale.

• Loosen material by tumbling bucket & dry mixing before adding water.
• To ensure product performance, DO NOT divide or separate individual units into smaller portions. MIX ENTIRE CONTENTS AT ONE TIME.
• A drill (6 amp minimum) with a mixer blade turning at least 500 to 800 rpm is required. Drills with speeds greater than 800 RPMs may entrain air in the mix.
• DO NOT HAND MIX
• To begin the mixing process, add the proper amount of water:
  
  

  For Each	Add
  46 lb (20.9 kg) 5 gallon (18.9 L) bucket	1 U.S. gallon (3.8 L) of water
  11lb ( 4.99 kg) 2 gallon (7.6 L) bucket	1 U.S. quart (.95 L) of water

  
  
• Ideal water temperature is between 65°F/18°C and 75°F/24°C.
• After adding the water, it is very important to rapidly incorporate all of the dry SubZERO™ powders to achieve a uniform wet mixture within the first 30 seconds of mixing. Continue mixing per instructions below.
  

• Use only 3/8" (1 cm) clean washed pea gravel or 1/2" (1.3cm) #7 stone up to 75% or 35 lbs maximum by weight
• Add aggregate to material and water slurry after mixing for 30 seconds. Continue mixing per instructions below.
  

Mixing Notes:
SubZERO™ undergoes an exothermic chemical reaction during blending. Heat, the by-product of the reaction, is the best indication that the reaction is complete and that the product is ready to be poured. SubZERO™ has a critical mix temperature of 85°F/29°C which MUST BE REACHED before pouring to obtain optimum performance. (In cold weather, it may be impossible to reach the Critical Mix Temperature, therefore a 40°F/22°C rise in material temperature is mandatory to ensure that the necessary chemical reactions have taken place to deliver the desired performance characteristics) Mixing time to reach the Critical Mix Temperature will vary with ambient air and mix water temperatures, however, never mix SubZERO™ for less than 90 seconds. It is recommended that a thermal gun be used to ensure that the Critical Mix Temperature has been achieved.

• Working times are influenced by surface temperature and repair profile.
• Minimum NEAT profile thickness is 0.50" (1.3cm). There are no restrictions to the depth of the repair profile.
• For best results, CERATECH recommends monolithic placement of repair materials. Maintain a minimum thickness of 1.00 inch if repair material must be layered.
• Upon final set, the material can be saw-cut, drilled, sanded and/or polished
• Do not re-temper. The addition of water to the surface of the repair will negatively affect the materials final properties.
• General loading in 5 hours for wheeled traffic in temperatures above 20°F /-7°C. In ambient and/or surface temperatures below 20°F/- 7°C, extend the loading time ( Return to Service) by 30 minutes for each 10° below 20°F/-7°C.
• All previously existing joints must be re-established within 3-5 hours of final set depending on depth of repair profile.
• Self-curing in ambient temperatures of 0°F /-18°C and above.
• Protect repairs with blankets or equivalent for 4-6 hours in ambient temperatures below 0°F/-18°C.
  
• Clean all tools and equipment with water prior to the material reaching final set.

• See Material Safety Data Sheet (MSDS).
• This document does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this document to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
• Dispose of water materials in accordance with Federal, State, and Local regulations.
• The use of a dust mask, safety goggles and gloves is recommended.
• Keep out of reach of children.
