This non-slip 2 part epoxy provides a very durable and slightly more coarse non-slip surface than the aerosol version and is suitable for all windusrfing boards. Prepare the board by lightly sanding the existing surface with some 120 or 240 grade paper and remove dust using a cloth. Mask off all the areas not required for non-slip application, i.e rails, footstraps and pads. Next mix the required amount in a small roller tray, then apply evenly using a small gloss roller (not included, try Wickes or B&Q)
