I got 1 of these kits for a 280 sq ft pond. It works great. I tried others and what spray-Lining & Coatings said on their pond comparison is really truth. All others are more expensive and none are of this quality. My neighbors who have bigger ponds with more features bought extra sq ftg to just to apply this Seal Tite thicker. Thicker equates to more money but that and I learned using real polyurea is the trick,
