Metamark calendered or cast vinyl's that have a solvent based adhesive, such as Metamark 7 Series may be used for under water applications with the following guidelines.

1. The surface must be a smooth, flat 'high energy' surface. For compound curves use a Cast vinyl, such as MD7.
2. Apply the vinyl using a dry application method to a clean dry surface at +10'C, and allow 36 hours to cure before submersing in water. Squeegee all edges carefully, and the use of gentle heat over the graphic will improve the bond.
3. If the vinyl is applied with a wet application, allow sufficient time to fully cure before submersing in water.
4. If the graphic is exposed to high water flow, such as the leading edge of a graphic on boat hulls, then gentle heat may be used to improve the bond around this area.
5. For Digital media, ensure graphic is overlaminated to protect the print. For coloured vinyls, metallic vinyls will have reduced durability in salt water conditions.
