Heavy Duty Traffic Areas: The joint width should be a maximum of 3/4” (19 mm). The depth should be a mini-mum of 3 times the width, or 2.2” (57 mm). B. Miraclebond 1350 or Approved Equal 1. Always be sure the bonding surfaces are prepared in advance before starting a new cartridge or mixing product. If at all possible, schedule dispensing to consume an entire cartridge at one time with no interruption of epoxy flow. For quart kit, mix only enough Miracle Bond 1350 that can be used within 8 minutes at 75°F (24°C). 2. When bonding two surfaces together, make sure to completely fill all the gaps between the mating surfaces. 3. To achieve maximum flow and reduce fatigue, the tip of the nozzle can be snapped off at the narrowest point of the nozzle. 3.1.2 CARTRIDGE SET UP - ADHESIVE TECHNOLOGY PRODUCTS or Approved Equal A. Crackbond JF311 or Approved Equal 1. Shake the cartridge vigorously for 60 seconds, then stand upright for 5 minutes allowing any bubbles to rise to the top. 2. Insert cartridge into the dispenser. Make sure it is properly positioned with the shoulder of the cartridge flush with the front/top bracket of the dispenser. Point upward at about a 45° angle. Remove the plastic cap and plug from the top of the cartridge. 3. IMPORTANT: Before attaching the nozzle, balance the cartridge by slowly dispensing a small amount of materi-al into a disposable container until both materials flow evenly from the cartridge. Place nozzle onto cartridge and secure by threading in a clockwise direction. 4. Continue to point the nozzle upward at about a 45° angle away from yourself and others while slowly applying pressure to dispenser, moving product up through the nozzle until it reaches the tip. Dispense one stroke of material into a dispos-able container (1-2 quick bursts if using an air tool). The cartridge is now purged and ready for use. B. Miraclebond 1350 or Approved Equal 1. Remove plastic cap and plug from threaded end of cartridge. 2. Place cartridge into dispensing tool, ATC’s TM9HD is recommended. 3. Dispense small amount of adhesive into a disposable container until both flow from cartridge. 4. Attach mixing nozzle to cartridge and dispense a small amount of material into same waste container until a consistent color with no streaks is obtained. 3.1.3 INSTALLATION - ADHESIVE TECHNOLOGY PRODUCTS or Approved Equal A. Crackbond JF311 or ApprovedEqual 1. Substrate and environment must be completely dry without any presence of moisture prior to usage. 2. To fill cracks, use a saw or grinder with a dry diamond or concrete abrasive blade and cut along the crack opening it up to 3/16” to 1/4” wide. 3. The edges must be a 90° angle to the surface to avoid a feathered edge. 4. To repair a control joint, fill all spalls with CRACKBOND CSR polyurethane and allow to cure. 5. Recut the control joint to remove all filler materials and to reshape the spall repairs. 6. Blow out and remove all dust, dirt, debris, oil and any other contaminant from the control joint or crack. 7. Use backer rod or kiln dried sand prior to application of adhesive. Allow sufficient depth for joint filler based upon minimum recommend-ed depth of filler. 8. Place mixing nozzle directly over the joint or repair area. Dispense material using full smooth trigger pulls (no short choppy strokes) and allow material to gravity feed into the crack/joint. 9. Allow the CRACKBOND JF-311 to cure for a minimum of 45 minutes at 75° F (24°C ) then Section 030130 – Concrete Repair use a sharp floor scraper to shave excess material from top surface. Follow explicit instruction below for application of any topcoat. Full cure times are temperature dependent and can be found in Table 3. Note: If you have any difficulty in dispensing product, replace the nozzle with a new one. The product may have started curing in the nozzle which could affect the mix ratio. Never transfer a used nozzle to a new cartridge. Instead use a new nozzle with each new cartridge. For joints to be shaved, over-fill the crack/joint so that material is slightly higher than the face of the concrete slab you are repairing. See Table 4 for estimated Shave Time vs. Temperature Range of a 1/2 “ thick bead. TABLE 3: CRACKBOND JF-311 Cure Schedule 1,2,3 Base Material Temperature °F (°C) -11 (-24) 75 (24) 120 (49) Working Time Full Cure Time 6 hrs 48 hrs 2.5 hrs 24 hrs 30 mins 12 hrs 1. Working and full cure times are approximate, may be linearly interpolated between listed temperatures and are based on cartridge/nozzle system performance. 2. Application Temperature: Substrate and ambient air temperature should be from -40 to 120 °F (-40 to 49 °C). 3. When ambient or base material temperature falls below 40 °F (4 °C), condition the adhesive to 40 to 85 °F (4 to 29 °C) prior to use Table 4: CRACKBOND JF-311 Estimated Shave Time vs Temperature Range of a 1/2" thick bead Temp °F Temp °C Time 100120 38-49 80-99 70-79 60-69 50-59 40-49 0 to 40 -10 -20 -30 -40 27-38 21-27 16-21 10-15 4-10 -18 to 4 -23 -29 -34 -40 20 min 30 min 45 min 1.5 hrs 2 hrs 2-3 hrs 3-7 hrs 7.5 hrs 8 hrs 8.5 hrs 10 hrs B. Miraclebond 1350 or Approved Equal Use Miracle Bond 1350 for SMALL SPALL REPAIRS ONLY. A deeper or larger mass than recommended will generate excessive heat resulting in undesirable reactions such as bubbling and cracking. (***For larger spalls use slower cure Miracle Bond 1450) For Miracle Bond 1350, the spall should be ground to a depth of ½”(1.27cm) to 5/8”(1.6cm) deep and width no greater than 3” (7.6cm). Avoid a feathered edge by cutting around the spall into sound concrete with a grinder or circular saw using a diamond or concrete abrasive blade so the entire depth of the spall is consistent. For patching concrete, fill the void with the Miracle Bond epoxy to just above the surface level and trowel flush. 1. Place and secure injection ports with the Miracle Bond capping gel taking care not to leave any pin-holes. Port spacing should be approximately 6-12” (15.2 – 30.5 cm) apart (typically the width of the concrete member). Do not allow the epoxy to block the passage between the port and the crack face. 2. Place additional Miracle Bond between the ports making sure the entire face of the crack is sealed off and ports are securely fastened to the concrete. If the crack is evident and accessible on the back side of the concrete member seal with capping gel. 3. Allow the Miracle Bond to cure before injecting the crack with an ATC Crackbond product such as Crackbond LR321. NOTE: Epoxy cure is affected by temperature. Low temperatures will increase cure time, higher temperatures with decrease cure time.
