Hey guys I’ve searched quite a bit through the site and haven’t really found a definitive answer to coping/waterline tile grout missing. Most posts I find talk about actual tile grout and not the grout separating the coping and tile. I’ve seen deck-o-seal and a poly type sealant mentioned. I want to go through and finish removing all the grout that’s left in there and redu it. What is recommended for my particular situation? I’m assuming just go around the pool with a scraper to remove old grout? Probably will try to use a shop vac to help not destroy the pool. Thanks guys!!!!
