but im worried about the high cost of epoxy , and was looking for an alternative.

i found that some people have used some sort of 'pond paint' and was wondering if it is avalible in nz

One of our members made one. To quote him...

'The tank was made from 18mm construction plywood with fibreglass reinforced corners and resin coating on the inside of the tank. Over the fibreglass was epiglass 2-pack reaction lacer primer. The finish was 2 coats of black swimming pool paint. The glass front was 10mm thick. '

The tank was a corner one holding 600 litres. That tank was built in 2000 and is still going strong with no problems whatsoever.

Epoxy is expensive if you buy it from a hardware store or marine shop, but try a place like Altex http://www.altexcoatings.co.nz/where.htm buying direct from their depots is much cheaper (1/2 price compared to some brands).

I have built a couple of kayaks before(http://home.clear.net.nz/pages/grantglazer/Kayak/index.html ), and would apply the same principal to a plywood tank or pond (strength and water resistance needed). using fibreglass cloth would be a very good idea. You won't be slamming the tank into rocks like a kayak so 3oz cloth would be easier to use then the normal 6oz and all that you will need but the price difference between these 2 weights of cloth isn't much. Coating it with only epoxy or epoxy based paints i.e. pool paint could lead to the coating developing cracks overtime. Any crack or ding in the coating will start rot in the ply (even marine ply). The glass cloth will stop this from happening.

A full size sea kayak only costs $600 to build so a 5 foot tank / pond should be around the $200 mark (guessing here). Actually using the Stitch and Glue method you could make the pond any shape you want - why restrict yourself to it being square?
