269g plywood tank?

How much does this stuff cost? You might be able to just use good old rubberized coating.

You just use the PermaFlex, I believe, but I will email them to confirm.

From the Sani-Tred website:

"SANI-TRED PermaFlex is a single component (1 part), liquid rubber "ULTRA ADHESIVE" paint-like coating. After cure, there is little resemblance to paint. PermaFlex is a paint replacement product, self-priming, easy to use, easy to apply and cures reliably even in extremely cold temperatures."

• PermaFlex has the ability to cure tack-free in 4 hours, or less, at temperatures 70° F or higher and the ability to cure overnight at temperatures exceeding minus 15 below zero Fahrenheit and still retain its cured qualities.
• Freshly applied PermaFlex may be subjected to rain, snow, or extreme cold without affecting its curing.

yea i read that but on the site it also says "
Products Needed: PermaFlex, LRB (Liquid Rubber Base) and TAV (Thickening Activator)"



if you only need the permaflex then its only 100 per gallon plus shipping. thats less then the sweetwater epoxy paint.

From reading other information on the site, the LRB can ONLY be applied over top of the PermaFlex, which is applied as a primer of sorts. The TAV can be mixed with the LRB to create a caulk-like mixture that is used for "filling and sealing large voids, joints, seams, cracks, holes or rough areas on horizontal, vertical or inverted areas."

Once you fix any of those types of areas, you go back over the whole with more PermaFlex.

LRB is also used to level rough/uneven floors.

I think that you can just use PermaFlex, in multiple layers, without the LRB and TAV. Those are just used to provide slightly stronger protection for weak area's or cracks, or to level rough/uneven floor.

One gallon coats 240 sq ft, and costs $100.05 (+ shipping).

From the website:
"Standard Application Rate: 240 sq. ft. per gal on concrete, wood, block, brick, stone/mortar as well as other standard building materials. Approximately 300 sq. ft. per gal when applied to steel, aluminum, cast iron, fiberglass and most non-porous materials. After application and cure, PermaFlex leaves a thick layer of smooth rubber approximately four times the thickness of a household garbage bag, (2 coats - approx 14 mils thick)."

Oh yah, it also comes in 4 colors, Light Tan, Light Grey, Black, and Off White (which looks like white to me ).

Then it comes in 3 sizes:

1 quart = $42.95
1 gallon = $100.05
5 gallons = $475.25

Bingo! Here's the stuff. This might be a cheaper option. In the US, its called PermaDri

Yah, I finally heard back from the company. Here is what they recommend for a plywood fish tank with a glass front window:

____________________________________________________________
1. The first thing you would do is prepare the substrate. Meaning
remove any loose crumbly substrate, make sure the substrate is clean,
dry, free of any previous applied products, and foreign matter.

2. Prime the sealing surfaces of the glass using 'Sani-Tred 2-Part
Epoxy Primer' as shown below.

3. Prime the plywood with 1 coat of PermaFlex (240 sq ft per gal). Once the Epoxy Primer has become tack-free, apply 1 coat of
PermaFlex over the Epoxy Primer.

4. Patch and profile any joints, seams, cracks, holes and rough
areas using a 3/4" bead of LRB/TAV mixture (Liquid Rubber Base,
Thickening Activator).

5. Apply LRB (Liquid Rubber Base) or LRB/TAV mixture over the
entire surface to create a permanent, impervious, waterproof membrane.
Our life time warranted membrane is applied @ 80 sq' per gal (20 mil
thick).At this point the substrate is 100% waterproof.

* If possible, apply the LRB to horizontal surfaces and once
cured flip the aquarium to apply the LRB membrane to another horizontal
surface.

* If the above option is not applicable, LRB can be
mixed with TAV to create a thickened mixture which can be applied at any
thickness whether vertical or inverted. Less TAV can be used to create a
mixture of any viscosity.

6. Topcoat the surface with 1 coat of PermaFlex (240 sq' per gal).
If Metal Halide, VHO or any other extremely intense lighting will be
used apply 1 coat of a good 2-part epoxy or any extremely UV resistant
paint.

_____________________________________________________________
So, according to this email, I need:

1 gallon of PermaFlex = $100.05
1 gallon of LRB = $85.75
1 gallon of TAV = $47.95
2 half-pints 2-part epoxy primer = $30.00

Total = $263.75

That's more than I want to spend on a liner. I'll look into the PermaDri stuff, see how much of that I need and how much it will cost...

I checked out Ames Blue Max, which is $150 for a 5 gallon pail (and free shipping to my local Ace Hardware), but that comes out to 3 or 4 gallons more than I would need for this project...

Not sure on the PermaDri stuff either. I had corresponded with the company a few months ago, but can't seem to find my emails. I'm waiting to hear back from them now.

I really liked the idea of this PermaFlex, because it comes in different colors, and you can touch up any nicks or scratches without recoating the entire surface. It permanently bonds new-to-old, and it cures under just about any conditions you can think of (down to -35 or -45 F even!).

Just got this back from Sani-Tred. I asked if the PermaFlex did not create a watertight seal, if only the LRB did, and if I couldn't just use two layers of PermaFlex. Here is the response:
____________________________
All the products are waterproof
The PermaFlex is a coating; LRB/TAV is used for sealing joints, cracks &
holes, can be applied @ any thickness in 1 application
_________________________________________________

Not really sure what that means. I have a feeling that you can just use PermaFlex by itself (they showed a pond being coated with just permaflex), and use the LRB/TAV to reinforce seams. Not 100% though...

You should be able to just apply the Liquid Rubber and be done with it.
