help repairing stock tank

gwithrow · #1 08/16/12, 05:21 PM

I have a fairly large stock tank, galvanized or metal....anyway it has several little pin holes and it leaks....it is not that rusted and I would like to salvage it if it is possible...so does anyone have a good suggestion for what I might spray the inside with? or some other way to resurface the inside so that is water tight? The only thing that I could think of is the spray in bed liner stuff...but I wonder if that would be toxic?

I'd clean it and smear the area with a liberal coating of silicone caulking.

liquid rubber, its a epdm rubber.

Water based and peroxide cured.

they sell a product called pond boss 2000 also.

As near as I can tell same product just different cans.

pond pro is $117.25 a gallon and the liquid rubber is $63.25, just a guess but they probably figure the fish hobbyist will pay substantially more. roughly 54.00 dollars more.

Comes white and black.

Free shipping in the Continental US. has to be a 20 dollar value there on a gallon.

Spray on or brush and roll.

there is another that's called rubberize it, its a modified asphalt based product not sure about that one. says its safe for fish?

But as far as I know EPDM has UV stability and Safe for fish ponds which means it can not be toxic or leach.

if its only a few small holes i've used the gel epoxy and had good luck, but if its lots of holes it could get expensive.

a small bolt and washer and a small rubber washer, (usaly used a section of inter tube and punched a small hole in the center for the bolt,

I would take the cordless drill and drill a hole at the leak for the bolt, and put the steel washer on the bolt and then the rubber and put throught the hold and then washer and nut and tighten, I preferded to go from the inside out, (rubber on the inside), I did that lot of times, probly for close to 20 years before replacing it a few years ago the tank was only about 70 years old,

Truck bedliner would seal it also

Have you considered the spray-on rubberized sealant called: FlexSeal
As seen on tv. . . . where they take a perfectly good aluminum row boat;
cut out the bottom and replace the hole with a screen door! Then they
show off by spraying their product across the screen portion and prove
that it keeps water out by taking it for a trip on the local stock pond.
You get two (2) cans for $19.95, but might find it cheaper on ebay, etc.

Colors come in either black or white. Sounds like it might work in this situation.

think that's the same as the product I shared. Just in a aerosol and already catalyzed, probably thinned a little too. it does not cure till it come into contact with oxygen.

I think farminghandyman has the least expensive option. easiest too! neoprene washer would work in place of rubber though.

If this is a small area get a fiberglass repair kit for about $10 at the auto parts store or marine store. Mix the resin, spread over the inside of the tank where the holes are, squish in some of the cloth, and put another coat of resin over the top.

A friend took a sheet of heavy plastic and just put it in her tank. She had a roll of that heavy clear plastic and lots of it. She did not want to buy a new tank for the horses so she just rolled that plastic out in the tank and all the way out the sides. Then she put straw or hay bales on the edges to keep the horses off it. It worked for the whole summer. She put more hay there now and then.

We had a plastic tank that we repaired with "gorilla glue" several times. We just smeared it on there and let it dry. It made a bubble of yellow glue but it stayed good. Later a new hole appeared near the glue but we just smeared more on there. The tub has lasted like that for about 4 years now. We just keep smearing on more glue when we find a leak.

Good luck.

Replace the metal tank with a Rubbermaid tank. Plant next years tomatoes near the house in the old metal tank.

Here's another one:
I've used marine epoxy. Get it at the hardware store, it comes as a stick of play-doh like stuff. Pull off the needed amount, roll it around in your fingers till it's mixed, then smush it in the holes. Works. Cheap. No tools.

The old timers would pour a few inches of concrete in old leaky tanks
