G-Tape features a patented combination of solvent acrylic adhesive with an advanced backing substrate, making it the premium solution for extending the life of bearers and joists used in outdoor decks and most other building applications. The adhesive on G-Tape has a negative charge. Steel nails and screws have a positive charge. The adhesive is attracted to the steel and then seeps into the surface imperfections of the substrate host to make a seal for all round moisture protection after curing in approximately 72 hours.
