N E T POUR IN PLACE Splicing Technique A warm-up time of approximately 5 to 10 minutes is necessary to bring the splicing iron to the required 350°-380°F. The entire splicing operation involves three simple steps. Do not allow the iron to reach 400°F. PVC will degrade and turn dark. For TPE Waterstop, preheat iron 380° to 410°F. Overlap the two pieces of waterstop to be sliced and then cut with sharp knife or saw. This assures matching edges. IMPORTANT: Edges must be cut straight. Press the straight cut against the sides of the pre-heated splicing iron until the PVC melts, an 1/8" to 1/4", thematerial becomes soft and gummy. This takes approximately 3-5 minutes. Quickly remove the splicing iron and press the melted edges together to form a neat butt-splice. The joined sections should not be stretched or moved for 1 minute. To cool the material quickly, use cold water. Typical spliced sections and the manner of accomplishing them, are shown above.
