I gotta tell you, over the last weeks and months, I've seen a lot of crazy stuff coming across my desk regarding overcoating water tanks. I'm seeing multi coat, three four, five coat systems coming across my desk, high film build. And it's just kind of crazy to me. I mean, what are we trying to accomplish when we overcoat a water tank? GFX: What is the goal when overcoating a water tank? I mean, usually we have a tank in a town or a village or city and it's starting to look tired and maybe the constituents are complaining or something and it's just looking tired. It's not failing persay is just showing some rust, it's just looking tired and we want to brighten it up. Maybe we're maybe we don't have the budget money to completely restore it and strip it back down, restore it. Maybe we're trying to get it in line with the interior lining and then we're going to strip it all back down. So we're just trying to get maybe seven to 12 years out of that tank. GFX: Options for a tank coating designed to last 7-12 years So why would we put on these high film build coatings and all this stuff and spend all this money on an overcoat? Let me give you some advice. Thin to win, folks. Thin to win. What does this mean? GFX: Apply less product to get the same or better result It means literally putting on less product to get the same result are a better result. So the other thing I'm seeing crazy thing I'm seeing is people putting GFX: Fluoropolymer urethane coatings don't make sense for a 7-12 year solution Fluoropolymer urethanes on overcoats. Now, Fluoropopolymers are designed to last for twenty five thirty years. Excellent product. We sell them. I like them but in an overcoat system it doesn't make any sense why you have a twenty five year coating or 30 year coating that you're only going to expect to last for twelve years. It's like wasted money. I mean to me it's kind of like pimping out an eighty four K-car. Does that make sense. I mean it doesn't to me. I mean to each their own. I mean it's your money knock yourself out. But I mean I think it's a bad look and I wouldn't do it. But that's what it's like to me throwing good money away after bad. So but you know, what's the best way to do it? I mean, I would think that, you know, GFX: Recommended solution: power wash the tank, spot prep, apply coat of epoxy, overcoat the tank with a tie coat, apply one coat polysiloxane or polyurethane, if necessary for aesthetics, apply second coat power wash the tank and then and do your spot prep and then put a coat of epoxy on our system. We got macropoxy six forty six duraplate two thirty five macropoxy fifty five hundred whatever. Pick an epoxy. Put that on. Then overcoat the whole tank with a tie coat like our pre prime nine twenty or pre prime 5000. And then my favorite is put on one coat of Sherloxane eight hundred or one of our polyurethanes like Acrolon Ultra or something like that. And if you have two for aesthetic reasons put on a second coat, but only if you have to. GFX: Less is more - thin to win! So at the end of the day we want less is more thin to win when it comes to overcoating water tanks. And that's to me is the recipe for success. I've been doing this for a while and I think this is the proper way. Thin to win, folks. Thin to win. GFX: Scroll rolling up on water tank graphic and from spec to protect text
