STI Terrazzos – Terrazzo Polishing Pads

STI Terrazzo Pads are versatile 3″ resin diamond pads for wet-cutting and polishing epoxy- and portland-based terrazzo and stone. Thanks to a specialized matrix that cuts aggressively while leaving a fine scratch pattern, they handle multiple roles — first cut, closing step, and the first step of a restoration — on a single pad. As the patent holder — and members of the National Terrazzo & Mosaic Association (NTMA) — Substrate Technology is the genuine source for STI Terrazzo Pads.

Terrazzo Pads vs. Terrazzo REDZ

Both are 3″ wet resin pads for terrazzo and stone — pick by the job:

• STI Terrazzo Pads — versatile: first cut, closing, and restoration first step; aggressive matrix with a fine scratch pattern; cloth tab for easy removal
• Terrazzo REDZ — focused on the closing/polishing steps; no center hole to keep debris and spent diamonds from collecting

Where STI Terrazzo Pads Fit in the Process

Whether you’re installing new terrazzo or restoring an old floor, STI Terrazzo Pads handle the key cutting and polishing steps:

New epoxy or portland terrazzo:

1. First cut with STI Terrazzo Pads to flatten and expose the aggregate
2. Work through the grits (35 → 400) to refine
3. Close and polish with finer pads or Terrazzo REDZ

Restoring worn terrazzo:

1. Start with STI Terrazzo Pads as the first restoration step to cut through wear and damage
2. Progress through the grits to bring back clarity and shine

Their versatility — first cut, closing, and restoration on one pad — is what makes them a shop favorite.

Frequently Asked Questions

First cut or polishing? Both — the specialized matrix cuts aggressively but leaves a fine scratch pattern, so they work as a first cut, a closing step, or the first step of a restoration.

Epoxy or portland terrazzo? Both — plus stone and new unsealed concrete.

Wet or dry? Wet.
