"Match the labeled adhesive color to the hardener color before mixing. "When adhesive is property mixed, it has a limited "working life" during which joints may be bonded. Use of the adhesive beyond the working life is prohibited. ORecommended for secondary containment installations due to size of kit. 14rNumber of bonds depend on ambient temperature. JOINT ASSEMBLY Bell and Spigot Joint The Spigot Must Be Aligned and Looked in the Bell. A cocked or misaligned joint will result in false lock up and possible joint failure during testing or at a later date. When the temperature is below 65`F (18.3`C), pre -warm the bonding surfaces (after —� the joint has been cleaned). CAUTION: If a solvent is used, evaporation may be slow at extremely low temperatures. Use a hol air blower and apply heat uniformly to the bell and spigot until warm (not hot) to the touch. Check temperatunI by touching outside of tht bell and inside of the spigot to avoid contact with clean bonding surfaces. If hot to the touch, let cool before applying adhesive. If an electric heating collar is used to pre -warm, place the joint together dry, then heat the O.D. of the bell to avoid contaminating the spigot. Brush adhesive on both surfaces, applying a thin, uniform coating. To minimize contamination, apply adhesive to the bell first. Adhesive should always be worked into the machined surface by applying t pressure during application. This will "wet out" the machined surface and maintain the required thin bond line. Be sure that all machined surfaces in the bell and on the spigot and cut end of the pipe are uniformly covered. F -loess adhesive will make the joint more diffioult to lookup and oan result in a flow restriotion. Connections into fittings are made using the normal bell and spigot method. A threaded (r.A.B.) spigot can be bonded into a smooth bell (fitting), or a smooth spigot can be bonded into a threaded (T.A.B.) bell. • Align and lock the joint. For 2" (50 mm) fittings, insert spigot into the bell until surfaces touch, then push and turn at the same time until a lock is achieved. Only a quarter tum to C a half tum is usually needed. On 3" and 4" (75 and 100 mrn) diameter fittings, pushing and turning to lock the joint is impractical. A driving force may be used. If the adhesive or the pipe surfaces are cool, push and hold for a few seconds to allow time for the adhesive to start flowing out of the tapered joint. If additional force is needed, a rubber mallet or a strong piece of wood and hammer to drive the joint together is the preferred method. When the adhesive starts squeezing out of the joint, use stronger blows. Proper pipe alignment is important. Maintain back pressure against previously assembled joints to avoid shaking them loose. After the joint has started to make up, hit until no further engagement can be seen at the joint. When engagement stops, the joint is locked. Always check previous bonded joints to ensure they have not backed out. Do riot use additional force on a spigot. Check lock up by moving free end of pipe in an up-and- down or side-to-side motion. The movement must be sufficient to move the joint being checked. No movement should be visible in the joint. If any movernent exists, the joint is not locked up and the joint assembly procedure must be repeated.
