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. Pool Plaster Disc uses Matrix Abrasive bonding technology for controlled pool plaster surface correction in both dry and wet polishing.

Also available in 50 Grit and 120 Grit.
