InnoviSeal™ Water Stop Mastic is used for easy installation of IKO Innovi™ TPO thermoplastic polyolefin single-ply roofs. InnoviSeal Water Stop Mastic adheres to a broad array of materials, such as concrete, masonry, gypsum, metal, glass, plastic and wood. It is a low-VOC non-skinning and non-curing long-term moisture barrier that remains flexible, even at low temperatures, maintaining a positive seal. Its inherent flexibility as a TPO roof caulking also provides excellent gunnability. InnoviSeal Water Stop Mastic may be used in multiple applications, such as behind termination bars, under roof drains and as an acoustical, roof panel rib and vapor barrier sealant. No primer is required. InnoviSeal Water Stop Mastic is an excellent TPO general purpose sealant.
