hello all! i am new here and reaching out for some ideas/advice regarding the waterline of our concrete pool. we purchased our home last summer and enjoyed the pool, but it is in need of a face lift. the house was built in the 70s with a 17 x 34' in ground (what we believe to be) concrete with fine aggregate pool. The previous owner said they had three different companies try over the years but none could get tile to adhere to the border/waterline so they had painted it. It looks terrible. they didn't scrape off a lot of the adhesive that was left from the tile and just painted about a 6" band around the top edge of the pool - it is now bubbling, flaking, and chipping off. Other than this, the pool is in pretty darn good shape and we hate to resurface the whole thing at this point just because of the upper edge. We have been discussing using our power washer and a grinder to remove the paint and the old gunk that was left behind, but not sure what our options are after we get it clean. Do we try to tile it again after so many failed attempts? Or do we repaint it with appropriate prep work? Anyone ever stenciled this type of thing? I'd say within 5 years we will do a major face lift/overhaul, but what would you guys suggest for the time being? I'm open.
