I am refinishing a cabinet with a barn wood plank top. After sanding it down to 220 grit I applied a coat of linseed oil. Unfortunately while at work today it rained, and while it wasn't directly exposed it got wet enough to raise the grains.

Will I need to re-sand after it dries?

  • Assume you're talking about "Boiled Linseed Oil" (BLO)? – JPhi1618 Mar 14 '16 at 20:29
  • Yep, sorry for the confusion, I'm new to working with the stuff but I see that acronym a lot around here. – mreff555 Mar 14 '16 at 20:31

    Seems like the answer is simply "if you don't want raised grain on your wood". – isherwood Mar 14 '16 at 20:36

    Bring it indoors, give it a week to dry fully, and see where you're at. You shouldn't be keeping it outdoors if the final destination is indoors, it's going to change when it climatizes. – Harper - Reinstate Monica Mar 14 '16 at 20:46
  • Yeah but sanding indoors is fairly messy. – mreff555 Mar 14 '16 at 21:01

Sanding oily wood will quickly ruin your sand paper. However, whether it should be resanded depends on how much you care about the finish. As a matter of practice, when I make "fine" wooden pieces, I purposely wet the wood after my first 220 sanding; after allowing it to dry, I sand off the fibers (or grain as you mentioned). And I sometimes repeat the wet, dry, and sand routine if I really need get rid of those fibers. I do this so that few fibers appear if the wood accidentally gets wet, or especially if I am planning to use a water based polyurethane to seal it.

yes. wet wood will not de-fuzz when it dries.
