Does it matter how much time elapses between sanding a board and sealing it?

If it is reclaimed lumber, do you need to seal it same day you finish sanding it? Say it’s a 100 year old board and you take off all the gray and nastiness, do you need to seal it immediately? Or does it not matter at all?

What about new (but dried/seasoned) wood? Does that react differently?

Thanks much in advance!

I don’t know that it makes a difference, I regularly have a few days inbetween. I think that more important than the time between is to take into account the finish you are using and do the pre-finishing accordingly. I.E. – raising the grain beforehand if you are going with a water based finish.

I wouldn’t really go so far as to say time is of the essence after ya sand, but if you’re not going to do your finish work right away, I wouldn’t do your finish sanding, either. Just for the simple reason the more sanding you do on your wood, the more you open it up to air, moisture, etc. You could probably get away with doin’ your rough sanding, but I wouldn’t try to do any more than that, & then leave it sit for a long period of time. jmtcw. Enjoy your day.
