I use ropes to paint Silos. We use epoxy paint which invariably contaminates the ropes. Has there been any tests on these ropes for paint contamination
The issue: hard gunk on the rope decreases flexibility of the rope. Fibers may break when the gunk spot is flexed.
My suspicion: Kernmantle ropes will suffer less than conventional laid ropes.
Test: Take 3 feet off the end of your rope. Soak it in your paint, and allow to cure. Flex repeatedly. Test to breaking.
Note: You may find some help by lubricating the rope, or spraying it with silicone so that the paint doesn't wet the surface of the rope.
