Okay, I've got a finishing question..............
Okay, you have a board. Let's say a hardwood board since that's what we mostly use around here. You sand it initially, with let's say....100 grit, to get it generally smooth and round off the edges and so forth.
Is there a difference in finish material penetration, i.e. BLO, stain, gel stain, clear lacquer, clear poly, etc., between the sanded surface at 100 grit and continuing to finish down to 220? down to 400? 800? 1000? I realize the some finishes are meant to stay on the top of the surface and not actually penetrate so I'm asking genrally here:
Does the porosity of the wood change as you sand to a finer/smoother surface (before applying any finishing product)?
I seem to remember being told a long time ago that one can help keep end grain from absorbing too much finish material (and subsequently getting too dark) by sanding to the next higher grit or two. Does this sound right and does it apply to the above question?
Thanks for your insight, explanations and info.
