Wood fence color

The fence boards, if you used treated will darken with age and depending on location and amount of moisture around the fence, especially close to the ground, you may get some algae growth on the boards.

Stain/seal products will lengthen the time between the fence needing a cleaning by a fair amount and keep it looking much nicer.

How did you treat the top of the fence as far as construction? If you have your top stringer a couple feet below the top of your fence, there is a very good chance you will get a lot of warpage of boards and the top of the fence will look like a redneck with bad teeth with boards bending toward your yard and other bending toward the neighbors yard. My neighbor put up 8 ft. treated boards and that is what his fence is doing now.

Sounds like you did it right. I like the sloped concrete and I do that for every post I cement into the ground for the same reason----to direct water away from the wood.

I'm debating between the Behr Waterproofing Wood finish (clear/slight yellow/orange tint) or the ready seal wood finish that seems more like a straight oil.

Basically trying to spray something with either my airless sprayer or ideally my pump sprayer to keep the grey at bay for a few years at least. I'll wait till my moisture content drops a bit. It's all over the place from readings in the 40% range to 18%.

Here is the ugly side behind my house for reference.

Check out Sherwin Williams. I used their super deck stain on my porch and railing last year and it still looks great. They have a line called Woodscapes as well.
