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
