1) I am having erosion issues underneath our large waterfall's grotto ledge. Wondering if there is a good product to seal this? I have read of erosion from salt for grotto/waterfall but our pool is not SWG, so I guess this is just from the spray? There are chips 1"+ flaking off, never mind the gray concrete type powder this leaves in the pool so would love to seal it in, perhaps this offseason. Pretty much any time I go to brush there is a good amount of powder and debris underneath.
2) Also - should I apply similar/same product to the waterfall path itself (the top side where water flows), for this big waterfall plus other little falls?
This pool and waterfall built 2010 and no maintenance done to waterfall since to my knowledge....Thanks!
Photos below show waterfall design, closeup of front of ledge from below (you can see see where old finish separating) and from underneath in the grotto (old finish worn off and remainder all powdery to touch)
