MiscellaneousChemical & Cement Products –Select ProductsSure-Lift (J-6 WB) Water-Based BondbreakerMiscellaneous andChemical ProductsPRODUCT DESCRIPTIONSURE-LIFT J-6 WB is a liquid, V.O.C. compliant, waterbased,reactive and membrane forming bondbreaker foruse in tilt wall construction. J-6 WB is a special formulaof polymers and propriety ingredients designed to provideclean, easy lifting of tilt panels. J-6 WB has a fugitive dyefor ease of visual inspection during application and is alsoavailable without the dye upon special request.USEJ-6 WB is designed to allow for easy lifting of tilt wallpanels from properly designed, finished and cured concretecasting beds.BENEFITS• Water Based• Very low V.O.C.• Panels lift cleanly• Minimal panel residue• Resists construction foot traffic• VOCLess than 100 grams per liter. Complies with Federal &OTC Standards for Bond Breakers.NOTE:Prior to application, read, and follow all current (verifyliterature is current) literature instructions, limitations, andprecautions in this data sheet, on the MSDS, and on thelabel of the container prior to use.The instructions provided by this technical data sheet applyto general average site conditions such as concrete mixdesigns, finishing techniques, and site ambient conditions.Test applications should always be made by the enduser/purchaser prior to overall use of the bondbreaker.This is at a minimum necessary to verify that the amountsof bondbreaker purchased and anticipated to be appliedis sufficient to result in the correct application coveragerates and end performance of the product based upon thespecific site conditions.The concrete casting slab, waste slabs and tilt wallpanels must be properly designed, finished and curedin accordance with industry standards and guidelinesincluding those of ACI and TCA.APPLICATIONMixingThoroughly agitate the J-6 WB prior to each use. Eachbondbreaker drum will be supplied with an integral drummixer. Use only the built in drum mixer to achieve propermixing. Proper mixing of the bondbreaker prior to useis extremely important. The bondbreaker drum must bein a vertical position to effect proper mixing. Vigorouslymix each drum continuously for a minimum of 3 minutes.Re-mix if left to set overnight. Failure to properly mix andkeep the bondbreaker mixed over time will result in stickingpanelsThe casting bed should be free of all foreign material, salts,laitance and the J-6 WB protected, while drying, from allcontaminants or particulate matter (i.e., dust, dirt, etc.).Cure CoatConcrete casting slabs must be smooth, dense, sound,of adequate thickness, and well cured. Improperor inadequate curing or finishing will increase slabpermeability and decrease bondbreaker effectiveness. J-6WB can be used as an effective curing aid under limitedenvironmental conditions. However, it is recommended perACI & ASTM to cure the concrete in accordance with ASTMC-309. The use of Safe Cure & Seal (J-18), Day-ChemRez Cure (J-11W) or other approved Dayton Superior curingcompound meeting ASTM C-309 is recommended.Curing compounds must be allowed to fully dry prior to theapplication of the bond breaker coat. Contact Dayton SuperiorTechnical Services for additional information andrecommendations.Always apply the cure coat IMMEDIATELY after completionof troweling and final finishing and after the surface water hasdisappeared. In extremely hot windy or dry weather lightly fogthe slab with clean water prior to cure coat.If and when J-6 WB is used as the cure coat, apply uniformly @200 ft²/gal (4.9 m²/L). Over application of the J-6 WB cure coatmay result in delays due to longer drying time for the cure coat,panel discoloration and/or excessive bond breaker transfer tothe panel surface. Under application of the J-6 WB cure coatcan result in crazing or cracking of the casting slab surface aswell as a weakened and overly porous slab surface.SPRAY EQUIPMENTThe J-6 WB Bondbreaker must be applied by a high quality“low-pressure pump-up type sprayer” such as manufacturedby Hudson, Chapin or others. The tip size must be able toproduce a well atomized spray pattern. The sprayer must bekept under sufficient pressure to correctly atomize the J-6 WBwithout streaming, tailing, or spitting. A 1/2 (0.5) gal. /minute tipis generally recommended for most applications. The use of animproper sprayer, dirty sprayer, lower than adequate pressuresor wrong tip can result in an uneven application, and either overor under application.First Bondbreaker Coat:Just prior to placing the reinforcing steel, and within two weeksof pouring the panels, spray apply the first bondbreaker applicationof J-6 WB at 400 ft²/gal. (9.8m²/L) to the point of rejection.Spray at right angles to curing compound spray pattern. Specificsite conditions may dictate coverage rates other than the normalrecommended coverage rates. Adjust the actual applied ratesaccordingly.Second Bondbreaker CoatWait until first coat dries, approximately 2 hours dependingon temperature & humidity, and apply a second coat at rightangles to the previous coat. Coverage for the second coat willtypically be 550 to 700 ft²/gal. (13.5-17.2 m²/L). If light or whitespots appear within 10-40 minutes after spraying, those areasare extra porous and should be fogged with water followed bya reapplication of the J-6 WB at 550 to 700 ft²/gal. (13.5-17.2m²/L). Specific site conditions may dictate coverage rates otherthan the normal recommended coverage rates. Adjust the actualapplied rates accordingly.The number of bondbreaker coats and coverage rates necessaryto achieve a complete uniform coverage is highly dependanton the concrete casting slab mix design as well as itsinherent porosity, finishing techniques, and other related sitespecific ambient conditions. Adequate bondbreaker applicationis in large part dependant upon development of a uniform soaplike feel of the bondbreaker treated surface as well as beadingof water. Bondbreaker can also be checked by rolling up a smallball like amount under thumb pressure. Extremely porous orrough casting slabs will necessitate successive additional coatsof bondbreaker to achieve a consistent uniform membrane ofthe correct coverage rate and membrane thickness. Extremelyporous or otherwise absorptive slabs can also be fogged withwater to a saturated surface dry (SSD) condition prior to applicationof bondbreaker.BONDBREAKER TESTTo verify the integrity of the bondbreaker coat, sprinkle water onthe casting bed. (Water should bead up as on a freshly waxedautomobile). The applied dried material should have a soap likefeel uniformly over the substrate.114 02-09
Chemical Miscellaneous & Cement Products –Select ProductsThe application should appear uniform and continuous, withlight areas requiring re-application. Failure to verify properuniform application and coverage rates can result in panelsticking. Testing must be performed over a large enoughsurface area in an adequate testing frequency to provideaccurate and meaningful results.It is entirely the contractor’s responsibility to verify that thebondbreaker has been evenly and uniformly applied at therecommended application/coverage rates given the variousconcrete mix design, densities, finishes, and porosityconditions on each projectHOT WEATHER PROCEDURESIn hot weather, the casting slab must be flooded with waterto reduce its porosity and cool it down prior to the firstbond breaker application of J-6 WB. Thoroughly saturatethe slab with water, and then squeegee off the excess,removing all the free standing water from the surface, thenimmediately proceed with applying the first application ofthe J-6 WB. Delaying the application of the bondbreakerafter wetting of the slab will result in over penetration alessen bondbreaker effectiveness, and panel sticking mayresult. Prior to concrete placement wet down the castingslab with cool water; excessive water should be blown outimmediately prior to the concrete placement. Take carewhen placing concrete to avoid abrading or scouring thebond breaker on the casting bed as braded or scouredspots or areas may result in stuck panels. Discharge theconcrete into previously placed fresh concrete.DRY TIMEApproximately 2 hours at 70°F (21°C). Coolertemperatures higher humidity and thicker bondbreakercoats will extend the dry time.CLEAN <strong>UP</strong>For Tools & Equipment Use warm, soapy water. After theproduct dries, solvents such as xylene or mineral spiritsmay be necessary to remove the product.WASTE DISPOSALDispose of waste material and empty packaging inaccordance with all Federal, State and Local requirements.Refer to product’s MSDS for further information.ESTIMATED COVERAGECure Coat: 200 ft 2 /gal (4.9m 2 /l)Bondbreaker Coats:First Coat: 400 ft²/gal. (9.8 m²/L)Second Coat: 550-700 ft²/gal (13.5-17.2 m²/l)The above recommended coverage rates are averagesbased on average site and concrete conditions.Complete and uniform coverage of the casting slab variesconsiderably with variations in the placing, curing, concretemix design, density, finishing, and site specific ambientconditions. It is not possible for the recommendationsprovided by this data sheet to accommodate and accountfor all variables associated with the coverage rate andapplication of the bondbreaker. It is the contractor’sresponsibility to verify that the applied coverage rates andoverall application of the bondbreaker is commensuratewith the specific site variables and conditions.PACKAGINGItem # Package SizeGals Liter307914 Pails 5 18.9307915 Drums 55 208STORAGEThe J-6 WB should be stored in a tightly secured originalfactory container. Store in the horizontal position to preventmoisture accumulation on the drum head. Keep fromfreezing.LIMITATIONSAvoid using bondbreaker that may have frozen. Avoidcontamination by storing containers in clean, dry area andkeeping lids tightly sealed. The shelf life of J-6 WB is 9months when properly stored. Do not spray on reinforcingsteel.Never apply bondbreaker unless it has been thoroughlyand properly mixed before use.Not recommended when concrete mix designs using fly ashor other pozzolonic materials without first contacting theTechnical Services Dept. for specific recommendations. Flyash can result in slower concrete strength development.Failure to observe specific application rates and proceduresmay lead to sticking panels.Bondbreaker should be re-mixed at the start of each day.Not recommended for application to broom finished or otherwiserough, porous or weak unsound concrete.Do not apply in rain or if rain is forecast within 12 hours ofthe application. Casting slab surfaces exposed to rain mayrequire reapplication of the bondbreaker at a coverage rateat 550-700 ft²/gal (13.5-17.2 m²/l).Do not apply below 40°F(4°C) or when ambient temperatures are expected to fallbelow 40°F (4°C) within 12 hours.Not recommended for application to casting slabconcrete that has been cured with curing blankets orplastic coverings without first removing the salts from theconcrete’s surface before application of the bondbreaker.Surface salts can result in surface defects.Application of the bondbreaker as a cure coat during coolweather or when a moisture barrier has been used willresult in longer than normal drying times. Application intwo thin coats rather than one thick coat will reduce the drytime.Properly applied, casting beds and tilt panels can normallybe coated or sealed after appropriate cleaning and orsurface preparation of the surfaces. The manufacture ofthe coating, paint, sealer, adhesive or other subsequenttreatments should be consulted for specific substratecleaning and preparation requirements and instructionsprior to painting.The Tilt-Up Concrete Association (TCA) Tilt Tips “PaintingTilt-Up Panels” document should be understood andfollowed if painting of the tilt panels is anticipated. Overapplication can lead to excessive transfer to the panelsand potentially cause problems with subsequent paintadhesion. A mock up test panel of any subsequentapplication of paint/coatings or other membrane formingtreatments should always be applied and tested to verifyproper coating adhesion and adequate cleaning andsurface preparation of the tilt panels. Improper concretemix designs, overly porous or weak casting slab concrete,failure to properly finish and/or cure the concrete and/oruneven or improper application and insufficient mixing ofthe bondbreaker can lead to panel sticking.Miscellaneous andChemical Products02-09115
