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.

Also available in 50 Grit and 70 Grit.

It delivers a smooth, polished finish on all plaster types — marble, quartz (Diamond Brite), pebble (PebbleSheen), Hydrazzo®, and Durazzo®.
