The Pool Plaster Diamond Disc 50 Grit is designed for aggressive resurfacing and removal of coarse, heavy-scale, or overexposed plaster. Our NON-CORROSIVE Pool Plaster Disc has been used in polishing swimming pool plaster since 1986. Unlike traditional electroplated pads that use corrosive metals for bonding, our discs feature a NON-CORROSIVE matrix material, eliminating rust problems caused by residual water and use over time.

This 50 grit disc works effectively on all pool plaster finishes including marble, quartz, Pebblesheen, and specialty finishes like Durazzo and Hydrazzo. For best results, work in small sections, rinse away plaster residuals, and avoid overheating. Excessive heat can damage both the disc and the plaster surface. Always maintain a maximum of 3,500 RPMs during use.

Our 7″ diameter hook and loop backer pad (AG7529) should be used with the Pool Plaster Disc 50 Grit to ensure 100% contact with the surface. Using a smaller backing pad can cause uneven wear and reduce the life of the disc. See our How To Repair Rough Pool Plaster page for more detailed instructions and tips.

Pool plaster disc 50 grit is designed to remove coarse, heavy-scale, and overexposed pool finishes. Our NON-CORROSIVE Pool Plaster Disc has been used in smoothing and polishing swimming pool plaster since 1986. All diamond pads use a corrosive metal for diamond bonding unless specified because of the cost. That causes rust problems from the residuals most of the time after use. Our diamonds are bonded with a NON-CORROSIVE matrix material, unlike traditional electroplated pads. When using a pool plaster disc without water, it is important not to overheat the disc. After doing a 5 ft × 5 ft area, use a hose to wash off the plaster residual material remaining. This will keep the pool plaster disc and pool plaster from overheating. Excessive heat will cause a breakdown in the integrity of both pool plaster discs and pool plaster. Maximum 3500 RPMs. Our 7″ diameter hook and loop backer pad AG7529 used with our Pool Plaster Diamond Disc 50 Grit ensures 100% contact with the pool plaster finish you are resurfacing. (Using a smaller diameter backing pad will cause the pool plaster disc to wear unevenly and reduce its life of the pool plaster disc.)
