C PA n L] If you have any questions, please contact your Smith Fiberglass Products' representative. b. Bonding surfaces must be dry, so be sure all solvent has evaporated before applying adhesive. Adhesive mixing—Thoroughly mix the adhesive. Complete information and safety precautions are packaged with each adhesive kit. Review all safety precautions thor- oughly before mix- ing the adhesive. a. When the weather is cool or the adhe- sive has been stored in a cool environ- ment (60°F/16°C or below), prewarm the adhesive kits. Do not heat above 80°F (27°C)! See Fig. 1.6.6. In some cases, hardeners may crystallize. If this occurs, refer to the instructions provided in each kit. b. Empty all of the contents of the hardener bottle into the can of base adhesive (see Fig. 1.6.7). C. Mix all of the ad- hesive with all of the hardener. NEVER SPLIT A KIT. Do not spill hardener during the mixing process. Cut through the adhesive with the edge of the mixing stick to assist in mixing the two components. d. Mix until the ad- hesive has a uni- form color and a consistent flow off the mixing stick (see Fig. 1.6.8). Wipe down the sides, bottom, and under the rim of the can with the mixing stick to as- sure complete mixture. 3. Adhesive working life—Working life or pot life is the 0 time it takes for the adhesive to harden in the mixing SECTION 6 ♦ Installation can. This time is measured from the time the adhesive and hardener are first mixed. Working life is shorter at temperatures above 70°F (21°C) and becomes longer as the temperature drops below 70°F (21°C). Working life is affected by the quantity of mixed adhe- sive as well as by temperature. Use the following methods to increase the working life of adhesives: a. Occasionally stir the adhesive mixture during appli- cation. lei C h All ut t e a esive carton so that the height of the car- ton is the same as the adhesive can. Line the inside of the box with rags or paper towels, and wet the rags with solvent or ice (see Fig. 1.6.9). b.. FIGURE 1.6.9 DO NOT contami- nate the adhesive with solvent, ice, or water. Small ice chests or other containers used with freezer packs or ice bags also work well. Caution: If adhesive becomes warm and starts to harden in the container, discard immediately. DO NOT USE THIS ADHESIVE TO BOND A JOINT! t When adhesive is allowed to harden in the met- al container, the container may reach approxi- mately 4001 (205°C). Do not handle hot con- tainers without heavy gloves. This exothermic reaction will generate a dense, foul-smelling smoke. Therefore, place the container outdoors in an open area until it cools. Avoid inhaling smoke. 1.6.4 Joint Assembly 1. Bell and Spigot Joint—THE SPIGOT MUST BE ALIGNED AND LOCKED IN THE BELL. A cocked or misaligned joint will result in false lock-up and possi- ble joint failure either during testing or at a later date. a. When the temperature is below 70T (21°C), prewarm the bonding surfaces (after the joint has been cleaned and the cleaner has evaporated). Caution: Evaporation may be slow at extremely low tempera- tures. Use a hot air blower and apply heat uniformly to the bell and spigot until warm (not hot) to the touch (see Fig. 1.6.10). If torches are allowed on the job site (check local codes), use a clean -burning propane torch. Check temperature by touching out- side of the bell and inside of the spigot to avoid con- tact with clean bonding surfaces. If hot to the touch, let cool before applying adhesive.
