Hertron Prime Grind M — Stone Polish & Hardener

No orange peeling here. Hertron® Prime Grind M acts as both a polish and a hardener — it reacts with the stone’s surface to harden it (increasing wear resistance) and enhance its shine. Unlike outdated crystallization coatings that can cause “orange peeling” damage when done incorrectly or overused, Prime Grind M uses a unique vitrification process that polishes and hardens your stone while letting it breathe — no residue buildup.

Why Prime Grind M?

Traditional crystallization coatings can leave stone with “orange peeling” — surface damage that shows up when they’re applied incorrectly or overused, and they can seal the stone so it can’t breathe. Prime Grind M avoids both problems. Its vitrification process hardens and polishes the stone without that risk, and it prevents residue buildup so the stone keeps breathing. You get a harder, shinier, more durable surface — done the modern way.
