16.3.1.3.Apply the sealant and test the containment sump(See <br /> SECTION 16.4.)before backfilling to grade. <br /> 16.3.1.4.Before applying the sealant,check to see that the <br /> Abrade surfaces to be sealed are dry and free of contamination or frost. <br /> pl 16.3.1.5.Before applying the sealant,consult the Typical <br /> A Properties Table for Bostik and factor that information into the <br /> 3,. sealing process.(See TABLE 16-1.) <br /> B Typical Properties <br /> Abrade Property Time <br /> a �-- <br /> Working time 70 minutes <br /> Tack-free time 90 minutes <br /> Cure time @ 77°F 1.5-3 days <br /> FIGURE 16-4 TABLE 16-1 <br /> CAUTION <br /> Each sealant step must be allowed to set sufficiently before <br /> A _ -__Abrade attempting any further assembly work or testing.Do not <br /> bump or move the containment sump assembly and do not <br /> work on piping connections before the sealant has set <br /> Abrade sufficiently.Any movement of the sump body before <br /> B sealant sets may cause seal failure. <br /> 16.3.1.6.Allow the sealant to set(typically four to five hours) <br /> before performing the water test to the containment sump <br /> assembly. <br /> CAUTION <br /> Do not stand on any portion of the installed cover. This may <br /> result in damage that would prevent proper sealing. <br /> FIGURE 16-5 16.3.2.SEALING COLLAR TO CONTAINMENT SUMP BODY <br /> 16.2.6.Wipe the abraded surfaces clean with a clean,dry cloth 16.3.2.1.The sealant is applied using a standard caulking gun <br /> before applying sealant.Do not use oil-based solvents or water (not supplied by Xerxes).When ready to apply the sealant,cut <br /> to clean surfaces. the tip off the end of the sealant cartridge at the 1/4-inch mark. <br /> 16.2.7.Position the containment sump assembly on the collar to 16.3.2.2.The first application of the sealant is to place a row of <br /> verify fit and elevation(in other words,dry fit the sump on the 1/4-inch-diameter beads around the top of the collar radius, <br /> collar). where the incline section meets the vertical edge.(See FIGURE <br /> 16-6,A.) <br /> 16.2.8.Remove the containment sump assembly and <br /> temporarily store it in a location where the abraded areas are 16.3.2.3.The second application of the sealant is to place a row <br /> protected from dirt,grease and other contaminants. of 1l4-inch-diameter beads around the bottom surface of the <br /> vertical edge of the collar.(See FIGURE 16-6,B.) <br /> 16.3.SEALING AND ASSEMBLY OF CONTAINMENT SUMP D <br /> CAUTION A \ <br /> Read and follow all safety and application instructions for �I <br /> preparation and cure times.Failure to do so may cause B <br /> water-seal failure and/or result in minor or moderate injury. C <br /> L� <br /> 16.3.1.GENERAL <br /> 16.3.1.1.The sealant must be stored at a minimum of 60 <br /> degrees F and used within 6 months of receiving the material. FIGURE 16-6 <br /> 16.3.1.2.The sealant must be applied at a temperature above 16.3.2.4.Now,set the containment sump section on the collar <br /> 40 degrees F. and seat it firmly in place.
