How much epoxy for my mast?

[Hookturn]

I just bought a Newport Kite (12' dinghy). It has a 20' wooden mast that needs redone badly. Reading the posts here I have determined that a penetrating epoxy (before varnish) is the way to go, but how much do i need? Is 16 oz enough? Or will I need 32 oz? Thanks in advance for your help!

Very fun boat. I sailed one way back in the day when I was a kid after I sold my snowbird. the Kite has a very bendy mast, if you do put on an epoxy it might effect the way the mast bends and the epoxy may not flex as much as the mast and will crack under the spar varnish. I have even seen the wood crack because the epoxy cracked and the wood cracked with it. The spar varnish is really all that is needed, if keep out of the weather it will last a very long time. if it has to stay up make a slide on cover for it.

750 grams of epoxy is enough for a sqare meter of single layer application of glass fiber.

Thanks for the advice! I will just try the varnish then.

And you would have to put a layer of varnish over the epoxy to protect from UV light anyway. For future projects consider getting a bit more than you need. It lasts a long time, and will be useful in a bunch of places.

Is that a hollow wooden mast or solid?

" . . . needs redone badly"

Is it a repair or is it cosmetic?

The varnish is peeling and cracking off and it is a solid mast. I am interested in whether it might make sense to put a penetrating epoxy on just the bottom few inches of the mast as this seems to be the area that looks worst. That part doesn't bend but is wet most of the time. Any thoughts?

Thanks for all your help!
