ABSTRACT:
A process for preparing a lap seam for roofing comprising applying a butyl rubber-containing primer with a mesh pad to the EPDM membrane surfaces to be joined. The primer is applied with a long-handled applicator to permit the roofer to stand during priming. Thereafter a splice tape is positioned between the primed surfaces to form a seam structure and pressure is applied to the structure thus provided to form an adhesively-held lap seam characterized by being watertight and having superior peel strength when compared to other methods of making seam tapes.
