How to waterproof a plywood aquarium

[spartman]

Supposed to be used in ponds according to the label.
Monsterfish rescue had his tank setup with it.

Going to try using foam PVC sheet and silicone to line some small plywood breeders as a test for the inevitable monster tank. Using this:

Any advice/ input would be greatly appreciated.
This is available in 8ft x 4ft sheets in thicknesses of 3,5 and 10mm

A client of mine uses 3M 5200 on sailboat hulls if that's any indicator of strength I looked at it but decided on GE 1 Silicon at $4 a tube vs. 5200 @ about $15 a tube.

A for purchase, Ames Blue Max sells through Ace Hardware. If you don't have one near you then they will sell direct. $150 for 5 gallons, $49 per 1 gallon. The 5 gallon was professionally packed and shipped very affordabley.

Also, you wrote "3M 5200 has been found to work best for the viewing panes installation when using these products". Has anyone actually done any tests to confirm adherence of 3M 5200 to liquid rubber or vice versa? I know you said that you were going to but I never saw any updates in your build thread. As far as I know butyl or polyurethane caulk have been recommended by the liquid rubber reps. 3M 5200 is a great product and would probably work well but I personally haven't seen any comparisons or build journals that prove that it works "best".

I havent use the 3m 5200 but I did use the GE 2 XST paintable formula, then sealed it with 6 coats of Zavlar since the silicon isnt safe for fish, my tank has been up and running for a year and a half without any issues

blue seal looks promising.. has anyone ever tried it?

i have found that pond liners can sometimes put moisture into the wood and rot it out, my father works at the MN Zoo aquarium department and on their large concrete dolphin aquarium they used an epoxy paint

Would plastidip fall under the category of liquid rubber? You can actually buy it in 5 gallon contains with UV resistance.

Anyone else try it on a real tank?
