Hi fellas,
Is there a way to use something like fiberglass tape and glass resin to waterproof a wood cavity so it will indefinitely hold stagnant or running water?
Thanks

What’s it for?

I know shower liners are designed for this type thing.

There is a glue you can seal the seams with.

I should mention that I want to create a barrier between the wood and the water and not necessary “waterproof” the wood itself. Also, I would I prevent the barrier from sweating?

rwe2156, It is an irregular cavity in the wood that will be filled with water.

Yes, they do that on wooden boats quite frequently.

Yes. Just as you would for fiberglassing anything else. More like fiberglass cloth/weave, but you might be able to get away with tape.

Just don’t use the fiberglass matting that looks like a bunch of strands stuck together. That stuff is awful to work with. Get a woven mat.

Thanks a bunch. Yes, I have seen the cloth. It appears to be a lot more flexible.

Search Google for West System fiberglass and/or epoxy.

Would a small plastic pond or a flexible pond liner membrane work for your application?

I watched a show on building wood canoes and they glassed the bottom, you could see the wood right through it.

bigblockyeti, I don’t think that would work for this project unless I could melt the plastic. Rick M., that is exactly what I want and I think the west system will do that. The price is a shocker for sure. Amazon is advertising another similar product a little less with good review and they have some that is penetrating kind (bit more expensive though).

You can use epoxy and cloth (6oz) and it will be fine. If you use polyester resin (fibreglassing resin) .... It won’t, at least not for long. Depending on the application, epoxy alone could also work. I have made plywood fuel and water tanks this way ….. and a bath tub.

Cool video Rick. Thank you.
Paul, thanks the conformation. I ordered the cloth and the epoxy. Now all I need to figure out is how to execute what is in my head. Thanks a lot for the inputs.
