lining large plywood tank

[I<3fish]

This is what pond armor does, it hardens fairly fast, has no fumes, only takes one coat, is much cheaper, and is proven to be fish safe. Also, you can choose your color pigment in it.

The only problem I forsee with it "hardening like a rock" is flexibility issues. Anything you line the tank with needs to flex, even the glass needs to flex.

You can give it a go, but I still say use armour or liner. The liner does not have to look like ****, you can attach pieces of liner to each individual piece of wood then assemble. After you assemble you seal the joints with seaming tape that is normally used for combining liners together in a traditional pond. Inexpensive and quick!

You can pioneer this for us as you seem to have more disposable income than most (like scrivz said on ofish) but if it fails, I warned you

well scribbles is wrong. I don't have lots of disposable income. when you make 20 hr, live at home and dont pay any bills you save lots of money.
also how much flex do you have with your fish tanks? also even with pond liner or armor plywood still dose not flex a whole lot. why would you need a tank to flex?

well I have seen pond armor before but I am still not quite sure what I want. I will make a update when I make my mind up.

pond armour = leak proof when done right.... and you can paint over it to make the color you want

same with polyurea it comes in colors too. and I can be %100 sure it will be leak proof

I have never used polyurea but have always wanted to do so. Friends of mine have used it in other applications and have said it's a bit difficult to work with, specifically that it gels up bad and does not flow out well. Spraying it requires high dollar airless equipment and has some risks associated with it.

It is sprayed on as outdoor pond liners through the US and is supposed to be very durable, UV resistant and fish safe.

One significant problem with it is that silicone and other adhesives don't stick to it. This is true of the polyurea and polyurea blends, as I understand it.

If true, this would make attaching glass or acrylic difficult and would also mean you could not silicone the seams. Not being able to silicone the seams would mean you'd want to line the entire inside at once to avoid cold joints.

Also, polyurea is more flexible than epoxy so that should not be a problem.

If anyone has any information otherwise please post it here. There are a lot of different polyurea blends so I can't say my information applies to all things called polyurea.

Comeon... no one has read the website on this stuff... it does NOT harden like cement, it actually stays quite playable and has a elastomic ability of 405% which is HUGE!, it is colorable and generally seems to adhere to anything... and it's sprayable... seems like a great compitition product for Pond Armour.

Find out what the Product sells for Per gallon and what it's coverage rate is since no one here will look up your friend to come spray it at $3 a SQR FT, Although it's not a bad price to have it done for you

finally! i was reading through this thread waiting to see if someone is actually going to read about the stuff and follow the link posted. this stuff seems like just just as viable a solution as pond armor. the only thing with this stuff is that you can't really get it factory direct, you have to go through a retailer so there is going to be alot of varibility in pricing. and also it seems to me that it had been assumed this stuff has to be sprayed on, nothing has to be sprayed on. there's no reason you can't go to denfeld paints, see what they can get it for, follow the directions on the can and roll it on yourself. the point of DIY is to save money right, so paying a guy, to bring over his fancy equipment and look pretty doing it

There is a polyurea product called ReptShield that is marketed for wooden reptile enclosures. IIRC it has a coverage of 75 square feet per quart and is $35 per quart.

I suspect the listed coverage is on the high side, especially for a plywood tank. I'm also guessing polyurea can be bought in bulk for much cheaper.
