Dry vs. Wet

We recommend dry use for most pool resurfacing projects because it’s simple and cost-effective. Any quality 7″ variable-speed polisher with GFCI or cordless works. Wet use can extend disc life, but requires specialized water-fed equipment.

⚠️ Safety: Keep RPM ≤ 3,500. Avoid overheating. Always use GFCI protection and proper PPE.
