ZENGRIT12 · 25 · GRADED SILICA QUARTZ
The grip, the wear surface and the mechanical key between coats. Washed, kiln-dried and screen-graded natural silica quartz.
What is ZENGRIT?
ZENGRIT is washed, kiln-dried and screen-graded natural silica quartz, supplied for broadcasting into wet resin. It is the aggregate that gives a POLYZEN broadcast floor its anti-skid profile, its wear surface and the mechanical key between coats. Quartz is chosen over softer fillers for a wearing surface because of its hardness: Mohs 7 against 3 for calcium carbonate and 1 for talc. It is also unaffected by dilute acids.
Grip or Build — Which Grade
| Grade | Grading | What It Does | Where It Goes |
|---|---|---|---|
| ZENGRIT 12 | 0.6 – 1.2 mm | An even, close grip profile — enough bite for traction under braking and steering, without the coarseness that makes a deck loud and hard to clean. The grade where profile matters more than build. | ZENDECK Park ZK-100 at 2 mm · ZENDECK Grip ZK-300 ramps · anti-skid profile on existing resin floors · mechanical key between coats · wet-area and process floors |
| ZENGRIT 25 | 1.2 – 2.5 mm | The thickness-building grade. The larger granule contributes real build to the section, so a 3 mm deck is reached economically, and the coarse profile stands up to heavy tyre traffic. | ZENDECK Park ZK-100 at 3 mm · heavy tyre-traffic decks and aisles · thickness-building broadcast layers · key under heavy seal coats · high-wear transitions and aprons |
Ordered by the Bag
ZENGRIT is not part of a pre-measured kit. It is ordered by the bag, and the quantity depends on the build-up and how much profile is to be retained. Broadcast quantities are confirmed on the System Data Sheet for the floor being laid.

The Full Build-Up
ZENGRIT is broadcast into the wet wearing coat. A complete POLYZEN floor is built from a primer, an optional levelling underlay, the wearing coat and — where an anti-skid or decorative profile is required — a broadcast aggregate.
