Buying Guide: Extra Fine Sandpaper Grits At A Glance
- What is extra fine grit? Typically 1000 to 20000 grit, used for polishing, finishing, and final smoothing.
- Wet vs dry sanding: Wet sanding reduces dust and heat, often yielding a smoother sheen; dry sanding is faster for material removal at lower grit ranges.
- Material considerations: Silicon carbide is common for metal and automotive work; aluminum oxide is common for wood and general purpose.
- Sheet size and handling: Standard 9 x 3.6 inches sheets fit most blocks; finger cots or gloves can help when finishing delicate parts.
- Grit progression: Start with a coarser grit to shape, then move through finer grits toward ultra-fine for a high-gloss finish.
Frequently Asked Questions
- What grit should I start with for finishing wood? – Start with 120–180 for shaping, then 220–400 for smoothing, and move to 800–2000 for final polishing.
- Is wet sanding necessary for metal polishing? – Wet sanding can produce finer finishes and reduce dust; use it for final steps on metal.
- Can I use the same sandpaper for wood and metal? – Yes, most silicon carbide and aluminum oxide papers work on both, but choose finer grits for metal finishing.
- How do I prevent clogging when wet sanding? – Keep the surface wet and clean the paper regularly to maintain cutting efficiency.
- What is the benefit of a wide grit range in a single kit? – It provides a complete finishing workflow from rough shaping to final polish without switching brands.
- Do ultra-fine grits remove material? – Ultra-fine grits primarily polish; they remove minimal material but improve surface quality.
