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 a GFCI or a cordless model works. Wet use can extend disc life, but requires specialized water-fed equipment. Pool Plaster Disc uses Matrix Abrasive bonding technology for controlled correction of pool plaster surfaces in both dry and wet polishing.

⚠️ Safety: Keep RPM ≤ 3,000. Avoid overheating. Always use GFCI protection and proper PPE.

Also available in 50 Grit and 70 Grit.
