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.

Surface 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: (Water temperature should be between 65°F/18°C and 75°F/24°C.)
   
  

  For Each	Add
  47lb (21.3 kg) -5 gal. (18.9 L) bucket	1 U.S. gal. (3.8L) of water
  47lb (21.3 kg) bag	1 U.S. gal. (3.8L) of water
  12lb (5.4 kg) -2 gal. (7.6 L) bucket	1 U.S. quart (.95L) of water

  
  
• After adding the water, it is very important to rapidly incorporate all of the dry Pavemend TR® powders into water to achieve a uniform wet mixture within the first 30 seconds of mixing.
• In ambient temperatures under 72°F/22°C, CERATECH highly recommends the use of a thermal gun or temperature probe to verify that a Critical Mix Temperature of 90°F/32°C has been reached. Place material into repair area when this temperature has been achieved.
• In ambient temperatures over 72°F/22°C and without using a thermal measuring gun or temperature probe, mix material for 4 1/2 minutes in ambient temperatures of 72°F /22°C to 80°F/27°C, mix for 3 1/2 minutes in ambient temperatures of 80°F/27°C to 90°F/32°C, mix for 3 minutes in ambient temperatures above 90°F/32°C and place.

• Use only 3/8“ (1 cm) clean washed pea gravel or 1/2”(1.3cm) #7 stone up to 100% maximum by weight
• Add aggregate to material and water slurry after mixing for 30 seconds. Continue mixing per NEAT instructions above.
• Continue mixing until Critical Mix Temperature of 90°F/32°C is reached but never less than 3 minutes. Place material into repair area and spread with a trowel, straightedge or squeegee, filling voids and edges.

For Aggregate Extension (Using Portable Rotating Drum Concrete Mixer )
Use 3/8” clean washed pea gravel or equivalent at no more than 100% by weight. ( For optimal finishing, do not extend Pavemend TR® by more than 60% by weight) Pre-mix pea gravel and water to create initial slurry mix. Add Pavemend TR® and record temperature after 1 minute. Mix for time indicated in Concrete Mixer Chart A. Pour and apply desired finish.
    
Mixing Notes
Pavemend TR® 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. Pavemend TR® has a Critical Mix Temperature of 90°F/32°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 Pavemend TR® for less than 2 minutes. It is recommended that a thermal gun or temperature probe be used to ensure that the Critical Mix Temperature has been achieved.

Application and finish

• Working times are influenced by surface temperature and repair profile.
• Minimum profile thickness is 0.06" (1.5mm). 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 initial set, a broom finish can be applied. 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 2.5 to 3 hours for wheeled traffic, 1 hour for foot traffic. In ambient and/or surface temperatures below 60°F/15°C, extend the loading time by 30 minutes for each 10° below 60°F/15°C.
• All previously existing joints must be re-established within 1-3 hours of final set.
• Self-curing
• 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.
