I have a project I’m working on made out of red oak. After giving a good sanding, I wet the whole thing to open up the pores before final sanding. After it dried, there were a bunch of black spots embedded in the wood that weren’t there before. I’ve never had this happen to me ever, and don’t know what it is. I bought the material rough sawn so any foreign material on the outside should be gone. I used Gator sanding discs and Norton sandpaper on it, which I don’t believe have anything in them to cause this. There was no foreign material present on the rag I wet it with. The black spots sand off, but not easily.
My main concern is if this will come back when I apply finish (Waterlox). Also I’m just curious what it may be. Like I said I’ve used the same equipment and processes and have never had this happen. Btw, the camera used for the pictures stinks, the horizontal lines are from the light.
