Sandpaper is an abrasive material that is often used at construction sites or furniture workshops.
Proper sanding creates the best finishes, whether you're working with wood, metal or drywall.
Aluminum oxide is a common sandpaper type that works on wood, plastic, metal and drywall. The particles break during sanding, constantly exposing new, sharp edges. Aluminum oxide sandpaper is long-lasting, making it a popular choice for power sanding,but you can also use it for hand sanding.
The grit number of a sanding product indicates the size of the abrasive particles. The lower the number, the larger the abrasive particles - they remove more material but create more noticeable scratches. A higher number indicates smaller particles which don't remove as much material but leave a finer, more polished appearance.
Sanding projects use several grit sizes, starting with lower-number grits and moving up the scale to finer, higher-number grits. Each higher grit removes scratches from the previous grit, creating an increasingly smooth surface.
There is a wide range of grit numbers available, from 24 for heavy material removal to 2000 and beyond for working with automotive finishes. The specific grit numbers you need vary by project and the material you're sanding, so follow the abrasive product manufacturer's recommendations.
