I've got 110 linear ft of mastic to replace. My gap is fairly uniform 1'2 to 3/4 wide. When I researched this last Deck-o-seal reigned supreme in pool mastic. I've never done mastic before. I am not a complete incompetent in DIY. My question is for this size of a job should I just buck up and go the 2 part Deck-o-seal route? Of maybe 1 pt Deck-o-seal would be easier. Buying it in tubes which is the only way I've seen it I'm willing to bet that way are more expensive/ There are other single part pool mastics out there now. Has anyone else had to make this same decision recently? I would appreciate learning for your experience.
