PlasterKing Resin Polishing Pads — High-Performance Pool Plaster Polishing

Technical Specifications

PlasterKing Pad Full Product Line

Unlike generic polishing pads, the PlasterKing line is purpose-built for pool plaster and will not leave black marking on finished surfaces — a critical advantage for pool contractors who need a clean, professional result. The 5mm diamond layer provides significantly longer service life compared to thinner alternatives, and the Hook & Loop system ensures fast, tool-free pad changes on the job.

Key Features & Benefits

No Black Marking on Surface

The PlasterKing pad is specifically formulated so it does not leave black marking on pool plaster surfaces. This means contractors can deliver a clean, finished result without additional cleanup or remediation steps.

5mm Thick Diamond Layer for Extended Life

The 5mm diamond layer provides a substantial amount of abrasive material, translating directly into more polishing cycles per pad before replacement is needed. For contractors working on multiple pools, this reduces consumable costs over time.

Hook & Loop Attachment System

The Hook & Loop backing allows for fast, tool-free pad swaps between grits, minimizing downtime during multi-stage polishing sequences. It is compatible with all polishers of the pool contractor's choice.

High Maximum RPM Rating (5,500 RPM)

Rated to 5,500 RPM, the pad is safe for use with high-speed polishers commonly used in pool plaster applications. This rating gives contractors confidence when running the pad at full machine speed.

Best Cost/Performance for Plaster Polishing

Alpha Professional Tools positions the PlasterKing line as the best cost-to-performance option for plaster polishing, making it a practical choice for contractors managing consumable budgets across multiple job sites.

Available in Multiple Sizes and Grits

The PlasterKing line is available in 7" and 9" diameters with #50 (coarse) and #100 (finer) grit options, allowing contractors to select the right combination for each stage of the polishing process.

Common Applications

Pool Plaster Polishing

The primary application for the PlasterKing pad is polishing pool plaster surfaces. It is designed to work with water-fed polishers used by pool contractors in both new construction and renovation settings.

Multi-Stage Plaster Finishing

Used in sequence with the #50 (Yellow) and #100 (Red) grit pads, contractors can progress from initial surface preparation through to a refined finish on pool plaster.
