Be certain that the underside of the flap and the top side of the adjoining transition or LP is clean and dry. Remove any contaminates, including asphaltic materials off of lap ends by wiping with appropriate cleaners before applying CA-103 Adhesive. After the CA-103 has dried to a firm tacky, carefully fold the end flap down in place taking care to prevent wrinkles or entrapped air. After the flap is down in place, thoroughly roll with hand roller to remove any entrapped air and insure intimate contact. Insert nozzle tip of hand held hot-air welder into splice area.
Heat fuse the underside of the top flap with the top side of the adjoining material.
Work from butt edge to flap edge pressing material firmly together, using pressure with hand roller, thor-oughly roll down entire seam area. Use caution so that the seam is not overheated. Work edge of splice seam last. Be sure to fuse edge while applying pressure with hand roller back and forth across finished seam. Two coats of edge sealant make a better job.
