At Substrate Technology, we’re always bringing in new products — but some of our best tools have been quietly getting the job done for years. Two of them deserve a fresh look: our STI CASH Pads and the SPIN-1 Pad System. If you polish concrete, terrazzo, or marble, these proven, solutions might be exactly what you’ve been missing — and they’re often more affordable and more versatile than you’d expect.
Here’s a refresher on what each one does, and how to know which is right for your job.
STI CASH Pads: One Pad System for Concrete, Terrazzo & Marble
The STI CASH Pads are resin-bond diamond polishing pads that bring concrete, terrazzo, and marble to a smooth, high-gloss finish. What makes them so useful is their versatility — one family of pads handles all three surfaces, stepping through the grits to refine each one to a clean, reflective shine. Whether you’re polishing a concrete floor, restoring terrazzo, or working marble, the CASH Pads have you covered.
The Simple 3-Step System
CASH Pads work in three progressive steps to build your shine — run them in order and stop at the level you want:
- Step 1 → a 1000-level satin finish (and preps the surface for the next step)
- Step 2 → refines it up to a 2000-level, higher gloss
- Step 3 → takes it to a 3000-level, high-gloss/mirror finish
Run all three for a high-gloss, reflective floor, or stop earlier for a softer satin look. They run wet or dry, and they’re available in a wide range of sizes — 17″ and 21″ for most electric buffers and swing machines, a 7″ size for hand grinders, and most diameters between 7″ and 27″.
Best for: polished concrete, terrazzo restoration, and marble polishing — on buffers, swing machines, or hand grinders.
SPIN-1 Pad System: Fast, High-Gloss Polishing on New Concrete
If you’re polishing new, smooth, steel-troweled concrete, the SPIN-1 Pad System is one of the fastest routes to a beautiful high-gloss finish — and it does the work in a fraction of the time compared to large polishing machines. These are diamond-impregnated natural-fiber burnisher pads that run on a high-speed burnisher (propane or electric), wet or dry, taking the floor through a five-grit polishing sequence to a clean, reflective shine.
The 5-Grit SPIN-1 Sequence
SPIN-1 comes in five grits, run coarse to fine (never reverse the order):
- #1 — most aggressive
- #2 — fine
- #3 — super fine
- #4 — polish
- #5 — buff
Depending on your floor and the finish you want, you can run all five or just a few steps. Each pad treats approximately 20,000 square feet, and they’re available in 17″, 21″, and 27″ sizes. SPIN-1 is also excellent for polish restoration and buffing guard products.
Is Your Floor a Candidate?
SPIN-1 is designed for new, smooth concrete — at least 4,000 PSI, 28+ days old, steel-troweled, and free of sealers or coatings. If your floor is older, coated, or rough, a traditional grind-and-polish system is the better route (and we can point you there).
Best for: fast, high-gloss polishing of new troweled concrete on a high-speed burnisher.
Which One Is Right for You?
Both deliver a beautiful polished finish — they’re just built for different jobs:
- Choose CASH Pads if you work across multiple surfaces (concrete, terrazzo, marble) and want a versatile pad system that runs on buffers, swing machines, or hand grinders. Great for terrazzo and marble restoration as well as concrete.
- Choose SPIN-1 if you’re polishing new, smooth, troweled concrete and want the fastest route to a high-gloss finish using a high-speed burnisher.
Not sure which fits your project? That’s exactly what we’re here for. We’ve been helping contractors choose the right polishing solution for years, and we’ll help you match the right pads to your floor, your machine, and the finish you’re after.
