A bad finish on a cherry vanity made me rethink my whole sanding routine
I was finishing a custom cherry vanity for a client in Boise, and the top coat looked awful. It was blotchy and rough, even after three coats. I was ready to blame the new brand of lacquer I was trying. Then my buddy, who runs a shop across town, stopped by. He ran his hand over the raw wood before I sealed it and just said, 'You're still sanding to 220, right?' I was. He told me to feel it again, but with a damp rag to raise the grain. The surface felt like sandpaper. I'd been sanding dry, which leaves tiny wood fibers standing up. When the finish hits them, they swell and make a rough surface. Now I do a light water pop after 180 grit, let it dry, and *then* sand with 220. It adds a step but the difference is night and day. Anyone have a different method for dealing with grain raise on open-pored woods?
