I bought a 5/6" x 4" ceder fence board for a spacer on hinge for a pump cover, not thinking that it was green wood. I used my jointer to smooth the surface and reduce it to the 3/8" thickness I needed. In that process, I realized that the wood was very wet.
Doing some online research, the most frequent opinion seemed to be to allow 4-5 weeks fence boards to dry before painting. I put the board in my furnace room, which my gas water heater keeps quite warm. A day or so later, I thought to weigh the board with my kitchen scale at 562g. A few days later, it weighed 499g. a few days later it was down to around 482g and seems to be about the same now, a couple of days after that.
I now am wondering if the lack of more weight loss recently might indicate that it is dry enough to paint now, even though it has only been maybe a week since I planed it down.
