How To Choose Sandpaper For Your Next Project

Hello,

Sanding is one of the most important steps in woodworking. The right sandpaper ensures a smooth surface, highlights natural grain, and prepares wood for finishing. Choosing the best wood sandpapers depends on understanding abrasive types, grit sizes, and the project at hand.

What to Look For in Wood Sandpaper

When selecting sandpaper for woodworking, consider the following factors:

• Abrasive material: Aluminum oxide is versatile and long-lasting. Zirconia and ceramic are tougher and better for heavy sanding. Silicon carbide is excellent for finer finishes and sanding between coats.
• Grit size: Coarse grits (40–80) are used for shaping or removing rough material. Medium grits (100–150) are ideal for smoothing. Fine to extra-fine grits (180–320+) prepare wood for staining or finishing.
• Backing and flexibility: Paper-backed sandpaper is economical, while cloth-backed options are stronger and better for power sanders. Flexible sheets are useful for hand-sanding curves and details.
• Coating type: Open-coat sandpapers shed dust better and resist clogging, making them perfect for softwoods and resinous species. Closed-coat sandpapers provide more abrasive coverage for harder woods.
