How It Works
Four things to understand: how the barrier works, the system it powers, why we measure results in the field, and how we handle safety.
01 — The Science
Most surface products do their job while they're wet, then wash away with the very next cleaning — leaving nothing behind to protect the surface in between.
Shield3 works differently. Its surface layer bonds onto the surface and stays put, forming a persistent, non-leaching protective barrier that stays active between routine cleanings.
That's why we describe Shield3 as a barrier that complements your cleaning — not a replacement for it. You keep cleaning as you always have; the bonded barrier works in the gap between those cleanings.
02 — The System
One system that meets contamination where it travels — across surfaces, through stored air, and on gear.
A bonded barrier for high-touch surfaces — benches, handles, mats, lockers. It bonds on and keeps protecting after it dries, active between routine cleanings.
Treatment for the air inside enclosed storage — closed lockers, gear bags, and equipment rooms — where moisture and odor build up between uses.
Protection carried into the wash, reaching gear and uniforms. In active development — not yet a shipping product.

03 — Why We Test
ATP testing measures bioburden — the amount of biological residue on a surface — reported in relative light units (RLU). It's a fast, standard way to gauge how clean a surface is.
In the field, we take an RLU reading before treatment and again after, on the same marked zones, to document the change in surface bioburden under real conditions.
We keep this field evidence separate from our laboratory validation, and we report ATP results as bioburden measurements — not as pathogen-specific kill claims.
04 — Safety
Straight answers for athletic directors, facilities staff, and risk managers. What the testing says, what the label requires, and how we apply it in your building.
The Layer 1 surface chemistry was evaluated in GLP acute-toxicity studies run to EPA test guidelines (OCSPP 870 series) and rated on EPA's four-category scale, where Category IV is the least toxic.
| Skin irritation | Category IV | Non-irritating (irritation index 0.0) |
| Eye irritation | Category III | Minimally irritating; no effects at 48 hours |
| Acute oral | No effects | No mortality, no clinical signs of toxicity |
| Acute inhalation | No effects | No mortality at 2.09 mg/L (LC50 > 2.09 mg/L) |

The surface product is a ready-to-use, alcohol-based liquid. Its label carries a flammable-liquid warning and a GHS eye-irritation warning, and it sets the rules for how it is applied. We don't work around those rules — we build the service on them.
No dilution, no mixing on site. Same formulation every visit.
Layer 2 inserts are humidity-activated and placed in enclosed storage — lockers, bags, equipment rooms — following the manufacturer's placement guidance. SDS provided.
Our products are not EPA registered and we don't represent them as such. Shield3 complements — does not replace — routine cleaning.
An empty facility, after hours. A backpack electrostatic sprayer. An applicator in the PPE the label calls for. Marked ATP zones swabbed before, and again after. Then surfaces dry, we confirm, and your program comes back in the morning to a documented result — not a promise.
