How to Apply a Weathered Finish to New Wood Siding
If you’ve got weathered-wood siding to repair or replace, you could put up fresh wood and wait for it to weather in and look natural, but there’s a better way.
I’d like to attribute this tip, but it’s anonymous. I heard somebody talking about this in a lumber yard on the West Coast twenty years ago. The idea was that you take baking soda, mix it with water, and paint it onto the kind of wood you would use outside–something with a lot of tannins in it. Watch the video to see if it works.
