Pavemend SLQ™ is a cementitious, very rapid setting, semi-leveling structural repair mortar with a gel state consistency sufficient for troweling up minor sloped grades and for aggregate extension. It is a single component powder that is water activated. Pavemend SLQ™ has 4 to 6 minutes of working time and will reach compressive strengths of more than 3,000 psi within 60 minutes of final set; making it the premier choice for critical infrastructure repair scenarios where a one hour return to service is of paramount importance! Designed for use in horizontal and sloped applications, Pavemend SLQ™ can be applied in ambient temperature ranges from zero to 90 degrees Fahrenheit without special mixing or curing equipment.

Recommended Uses
Pavemend SLQ™ is an ideal repair material for roads and bridges, airport runways, warehouse or manufacturing facility floors, post-tension cable repairs and form and pour projects.

Features and Benefits

• Not recommended for surface temperatures above 110°F/43°C or below 0°F/-18°C
• Not for submerged applications
• Will not bond to polymers
• Cannot be pumped
• Must be mixed with drill and paddle - Pavemend SLQ™ cannot be mixed in grout mixer or rotating drum concrete mixers due to rapid set times

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.

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

  
  
• In extremely warm conditions, add up to 1 cup of additional water to 5 gallon units, add 1/2 cup to 2 gallon units.
• 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 Pavemend SLQ™ powders into water to achieve a uniform wet mixture within the first 30 seconds of mixing.
• If ambient temperatures are above 85°F/29°C, mix material for 2 minutes and use cold water at approximately 55°F/13°C. If temperatures are below 72°F/22°C mix until Critical Mix Temperature of 85°F/29°C is reached, but not 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. Place material into repair area and spread with a trowel, straightedge or squeegee, filling voids and edges.

• Use only 3/8“ (1 cm) or 1/2”(1.3cm) #7 clean washed fractured stone up to 100% maximum by weight (For best finishing characteristics, extend by no more than 75%).
• Add aggregate to material and water slurry after mixing for 30 seconds.
• See mixing times for NEAT application above.

MIXING NOTES
Pavemend SLQ™ 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 SLQ™ has a Critical Mix Temperature of 85°F/29°C which MUST BE REACHED before placing 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 SLQ™ for less than 2 minutes regardless of ambient temperatures. It is recommended that a thermal gun or temperature probe 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 0.06" (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 1.0 hour for wheeled traffic and 20 minutes for foot traffic. For applications 0.5” thick and greater, in ambient and/or surface temperatures below 50°F/10°C, extend the loading time by 30 minutes for each 10° below 50°F/10°C. For applications 1.00” thick and greater, in ambient and/or surface temperatures below 40°F/4°C, extend the loading time by 30 minutes for each 10° below 40°F/4°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.
