High-performance hook-and-loop diamond polishing pad engineered for smoothing and polishing pool plaster. The PlasterKing® system features a 5 mm thick diamond layer for long life and is offered in 7" and 9" diameters with #50 (yellow) and #100 (red) grits. Unlike many polishing pads, PlasterKing® leaves no black marking on the plaster surface. Designed for wet use, the pads pair with Alpha® PlasterKing® Backer Pads (e.g. PK710HH) and work with any standard hook-and-loop polisher of the pool contractor’s choice.

MP758HL is the recommended backer pad for the PlasterKing® polishing pads. MP658HL may be used when more flexibility is needed to polish tight corners. For pneumatic underwater polishers (e.g. AIR-680UW), use the reverse-thread PK710HH backer.
No. PlasterKing® is wet-use only. The bonding system is engineered for wet performance, and dry use will damage the diamond layer and shorten pad life.
Yes, PlasterKing® pads are suitable for long-term use with the Alpha® AIR-680UW underwater pneumatic polisher.
Most likely, Alpha® will begin offering electroplated PlasterKing® pads for the next spring season. Contact DST to confirm availability.
Pool contractors typically stop polishing at #100 grit since once water covers the plaster, the color is enhanced and higher grits offer no practical benefit.
Yes. Most pool applications occur April through Memorial Day, and October is also a busy season — before and after pool season is when contractors do most polishing.
