Get the Right Grit

posted 6/1/2015 in Kreg Tool Tips: Sanding by Kreg Tool Company

For most boards, you’ll start out with 120-grit sandpaper. Rough lumber with noticeable marks or scratches may require a coarser grit first. If the project will be painted, 120 should be adequate. If you’ll be applying stain or finish, continue sanding with a finer paper. Progress through 150-grit and then 180, and that should be sufficient for most finishes. Plywood can usually start at 150 or 180; just be careful not to stand through the thin veneer. Regardless, consistency is key. Parts sanded to different smoothness may look and feel different when finish—and especially stain—are applied.
