Substrate Technology, Inc.

Prep/Master® Grinders, Dust Collectors, and Diamond Systems

Substrate Technology

This is our own line — the equipment and tooling we build, brand, and stand behind. As the makers of the Prep/Master® grinder and the source for STI diamond tooling, polishing systems, and patented terrazzo pads, we bring you products engineered from decades of real-world surface prep experience — and backed by experts who actually know the work. Call and talk to a real surface-prep expert, not a call center.

The Prep/Master® Grinder

The heart of our line: the Prep/Master® grinder — our own low-maintenance, gear-to-gear concrete grinder and polisher, built to last and available in a range of sizes. We design it, build it, and support it in-house. Learn more about the Prep/Master.

FL-07 Diamond Pads — Our #1 Patented Pad

Our best-selling pads, period: the FL-07 diamond pads are patented and exclusive to Substrate Technology — you can't buy them anywhere else. They're the go-to polishing pad for contractors who know them, fitting a wide range of grinders, and they deliver a consistent, high-quality polish step after step. We also offer them in a ring-type version for hand grinders for edges and detail work. There's one source for FL-07 — and it's us.

STI Diamond Systems & Tooling

Our color-coded diamond polishing systems (CLC, EGT, and TPS) take you from grind to polish on concrete and terrazzo — and we make the full range of STI diamond tooling to go with them:

  • Diamond tooling — grinding segments, prep tools, and polishing pads
  • Surface prep tooling — for coating and adhesive removal
  • EG attachment holders, adapters, and the parts that tie it all together
