am fixing up the old pool
started with water and that is now fine, thanks for the help
so on to the surround, putting loose slates back down
later work on the interior of the pool
see pic and red arrow, attached
the corner of the vertical and horizontal slates is very sharp, hard, hostile; also hard to grab to launch out of the pool
is there any device that can be applied to the corner to render it friendly and grab-able?
