Product Description: SL is a rapid setting, semi-leveling, self-consolidating, cementitious structural repair concrete. It is a single component powder that is water activated. SL has 15 to 20 minutes of working time and will reach compressive strengths of greater than 2,500 psi within 90 minutes of final set, and more than 7,000 psi at 28 days. Designed for use in horizontal, sloped, or form and pour repair applications, SL can be applied in ambient temperatures from 40°F – 120°F (4°C – 48°C). Typical Applications: Roads and bridges, airport runways, warehouse or manufacturing facility floors, post tension cable repairs and form and pour projects. Can be used as a temporary repair for asphalt pavement. Surface Preparation: • Substrates must be of load bearing capacity, and free from all potential bond breakers such as dirt, dust, grease, oil, sealers, curing compounds, laitance, loose or deteriorated concrete and any bond-inhibiting foreign substances. • Mechanically prepare surfaces to achieve a surface profile equal to CSP 5 – 7. Concrete Surface Profile as per ICRI Guideline No. 310.2R-2013. • All surfaces to be repaired should be saturated surface dry (SSD) but have no standing water. Hot surfaces should be cooled and shaded while cold surfaces should be heated and sheltered.Mechanically remove all loose materials by suitable means such as chipping hammer, chisel, sandblast, high pressure water blast (>5000 psi), or similar methods. Mixing: Bucket Mixing with Drill and Paddle • To ensure product performance, do not divide/separate individual units into smaller portions. Mix entire contents at one time. • Do not hand mix. 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. • For application temps near 72°F/22°C, the ideal water temperature is between 65°F/18°C and 75°F/24°C. 1. Loosen material by tumbling bucket & dry mixing before adding water. 2. To begin the mixing process, add the proper amount of water: For Each: Add: 51.8 lb (23.2 kg) unit
2 U.S. quarts (1.9 L) of water
3. After adding the water, it is very important to rapidly incorporate all of the

dry SL powders into water to achieve a uniform wet mixture within the first 30 seconds of mixing. Mix for 3½ minutes. Rotating Drum Concrete Mixer: Mix minimum 2 units at a time. 1. Pre-wet cement mixer with water then drain all water from mixer (away from repair area). 2. Start mixer and add 50% of total required mix water to concrete mixer

Pavemend SL™ (SL requires 2 quarts of water per 51.8 lb unit, therefore 2 units require 4 quarts, etc.) 3. Add pre-determined units of SL. 4. Add in remaining 50% of mix water. 5. Mix for 5 minutes total. 6. Pour all contents into repair area. 7. Clean mixer or repeat process for next batch. NOTES: 1. In ambient temperatures > 85°F/ 29°C, use cooler water (50°F/ 10°C to 60°F/16°C). 2. Working times will vary when mix water temperature’s are outside of these recommendations. Application: • Minimum product thickness 3/8” (0.9 cm) as packaged. There are no restrictions to the depth of product thickness. • Working times are influenced by surface temperature and repair profile. Working time can be extended by adding Aquafin’s Set Retarder Admixture to mix water. (See Set Retardant product data sheet for more information). • For best results, Aquafin recommends monolithic placement of repair materials. Maintain a minimum thickness of 1.0” if repair material must be layered. • Place onto properly prepared concrete substrate and spread with a trowel, come-a-long, or screed to a thickness that matches surrounding concrete. • Upon initial set, finish material to desired finish texture. • Upon final set, the material can be saw-cut, drilled, sanded and/or polished. DO NOT use additional water during the finishing process. • All previously existing joints must be re-established within 2-3 hours of final set. • General loading in 2 hours for wheeled traffic and 45 minutes for foot traffic after addition of water at 70°F (21°C). Add 30 minutes for every 10°F (6°C) drop in temperature. • Self-curing. • Clean all tools and equipment with water prior to the material reaching final set. Cured material must be mechanically removed.
