verhoevenc Posted January 12, 2006 Report Share Posted January 12, 2006 Alright... this is NOT cool! I was using some really hi-grit sandpaper to do some sanding. For some reason, paper changes color from normal sand to black, or something darker as the grit reaches like the 300 area... atleast in the brand I use. However, When I just sanded some of my spruce today up to 600 grit, it left parts of the grain black?!?! Almost like I had stained it black, and then sanded back... or like if I had black grain filled (even though the spruce doesn't need grain filling,,, but you get the idea). How do I get this black out?! -Water (but wouldn't that raise the grain and defeat the sanding I just did?) -Mineral Spirits? (does that raise grain too?) -Re-sand? (but it's already kinda thin....) Any help would be awesome, Chris PS: It didn't do this when I did the EXACT same procedure yesterday? Quote Link to comment Share on other sites More sharing options...
