Hi,

newbie here, making some windows for a shed. We’ve made some window frames out of 2×4s and are trying to figure out the best finish that will hold through the winter rain.

Based on the reading on this forum and elsewhere, the choices seem many and I was hoping to get some guidance from people who’ve done this before.

Here’s what I’ve found:

1) oil finishes, like danish oil, seem to withstand the weather well, but need very frequent re-application
2) poly finishes are very common (outdoor poly like varathane spar urethane from HD). Some seem to suggest it cracks over time or flakes in intense heat
3) epoxy finish + marine grade poly
4) outdoor paint, I’d like to avoid this as I quite like how the natural wood looks

are there other options? poly seems the most common, is there a branch/version that seem to work best for people? how often does it need attention and recoating?

thanks for any input,

Spike

i used automotive clear coat for some wood shelves in my shower after trying different things and having them fail and stripping and trying and eventually scoring some free auto clear coat. it was a 2 part so similar to epoxy, but obviously made for outdoor use. i get direct sun exposure through the window and constant soap and moisture on it. its been about 5 years and it is perfect. I applied it to black walnut.

thanks squazo. was that an acrylic based paint? I’m seeing both acrylic and urethane based and some links I read suggested acrylic will exfoliate.

also to add to my own list, I’ve noticed at HD they have patio finisher which seem to be agate urethane finishes, but those should definitely fair well in terms of waterproofing as that’s what they are designed for.

last but not least, thompson water seal is popping up in quite a few places, seems like it’s sold at Lowes but not HD, would love to hear anybody’s opinion if people have used that.
