OK, so I’ve started putting up 1” thick rough sawn hemlock boards (battens later) and pretty much went with the advice of “put it up wet and let it dry on the wall” method. The boards are fairly fresh cut. Yes, I know it’s going to shrink. This is on a garden shed for my wife. The original plan was (is?) to paint it. She was told and is ok with leaving it until late summer/early fall or even letting it go until next year to let the hemlock dry and “settle in”.
She saw me oiling a cut-off with linseed oil (just had to see what it looked like) and she liked that it didn’t darken the wood, but popped the grain some. She said, “Can we paint it with that? And if we do, can I still paint it later if I want?” I know we could still paint it later… oil-based primer and then a good exterior paint, but I wondered if oiling it sooner rather than later would have a negative effect on drying. I’m not talking about oiling it now while it’s still pretty fresh, but rather in a month or so. Would oiling it help to prevent some of the cracking/checking that I feel pretty confident will be coming? Would it still allow the wood to breathe enough to dry?
The pine facia and any other exposed “normal” lumber used for trim is getting primed and painted. Maybe as soon as this afternoon (at least primed well). I just don’t want to screw up the hemlock as I know it has some considerable drying to do.
Why paint and not stain?
I’m told they really don’t care much for hemlock, but that may only be because it’s green. Once it dries it may be more attractive. So it may get painted if for no other reason than to prevent the bees from eating it.
