Introduction: What is Sandpaper?

Sandpaper is a tool used to smooth surfaces through abrasion. It consists of paper or cloth coated with a type of mineral grit. The grit’s coarseness or fineness determines how much material is removed. Now, let’s learn how to use sandpaper effectively.

Step 1: Choose the Right Grit

You’ll need to choose the correct grit for the job. Here’s how:

  • Coarse Grit (40-60): For removing paint or heavy material.
  • Medium Grit (80-120): For initial sanding and smoothing.
  • Fine Grit (150-180): For final sanding and polishing.

Step 2: Prepare the Surface

Clean the surface thoroughly, removing any debris or dust. This ensures a smooth finish and prolongs the life of the sandpaper.

  2. Start with a low speed and increase as necessary.
  3. Move the sander evenly across the surface.

Common Errors and Solutions

Sanding against the grain on wood can cause scratches. Solution: Always sand in the direction of the grain.
