Pool Plaster Diamond Disc Pad 70 Grit can be used wet or dry to remove trowel marks and the first step in new polish pool plaster finishes. Our 70 Grit Pool Plaster Disc is made with selected 70 grit diamonds that are bonded to a specific NON-CORROSIVE material. Pebble Shine Diamond Disc 70 grit. Used to polish Durazzo Polished Marble Pool Finish and Hydrazzo Polished Marble Pool Finishes. The residuals from the bonding material will not stain swimming pool plaster, unlike other pads residue that stains pool plaster finishes over time. Works well with all variable speed polishers, and sanders. When using a pool plaster disc without water it is important not to overheat the disc by doing a 5 Ft. x 5 Ft. area then use a hose to wash off plaster residual material remaining. See our Resurface Rough Pool Plaster Guide
. 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 disc and pool plaster. Our 7" diameter hook and loop backer pad AG7529
used with our Pool Plaster Diamond Pad 120 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 uneven and reduce the life of the pool plaster disc) Do not exceed 3500 RPMs. CII-37-1008, DIAMOND DISC FLEX 7" 70 GRIT, 70D7FXO.
