Jefferys No 2 Black Marine Glue
This has been the premier choice for traditional deck seaming around the world for decades. Still produced in England from the original formula, it is as reliable today as throughout the last century. It will adhere tenaciously to the seam for many years, remaining flexible in low temperatures and withstanding softening at high temperatures. To apply, once carefully heated to a working temperature of around 370 degrees F (190 degrees C) it can be poured onto the prepared seams. Two applications are needed to ensure that all steam and air are released. Average usage 1kg to 10 metre run.
