Ball Surface Finish (Texture)

• Bowling balls can be sanded or polished
• Surface texture is measured in grit
  • Lower grit = rougher surface = earlier hook
  • Higher grit = smoother surface = later hook
• Common finishes:
  • Sanded (e.g., 500–2000 grit)
  • Polished
  • Factory compound
• Surface adjustments significantly affect ball motion and are often customized by pro shops
