Hello,
I have a design made out of cardboard that I will be keeping outside
in the elements. �I need it to be able to hold rain water inside it,
so I'm wondering if there is any way to water proof it? �Here are some
ideas:
1) �What If I painted it with an oil based paint?
2) �How about using epoxy glue and covering the entire inside?
3) �What about coating the inside with Portland Cement?
4) �I could coat the inside with tin foil, then use epoxy on the

Is there a much better idea than these?
Thanks
It's not possible to waterproof cardboard. �I would buy some thin
sheetmetal (flashing?) and use your cardboard design as a pattern to cut
the metal.

buy PVC tank, think used 55 gallon drums.
It would help a bunch if OP told us what the heck this thing he built is
supposed to be. My gut impression isn't that it was a water tank, but
rather some sort of sculpture or yard art that he prototyped, and now
wants to avoid recreating in the proper materials.

As another poster said, painting it with fiberglass resin is the only
thing that will give more than a few days of waterproofing, but that
stuff is nasty and expensive. Finding a good tinsmith to recreate it in
copper or something would be the traditional solution.
