Hull Pro is 100% Biocide-Free. Here is What That Actually Means.
No copper. No toxic chemicals leaching into the water your family swims in. No microplastics. Hull Pro protects your hull without poisoning the ecosystem around it — and performs better than traditional bottom paint while doing it.
What this means for you and your waterways
Hull Pro — The Environmental Summary.
No biocides in the water
Traditional bottom paints continuously leach copper-based biocides designed to kill marine organisms. Hull Pro's applied formula contains no biocides — nothing leaches, nothing accumulates in the sediment or food chain.
No microplastics
Ablative antifouling paints shed microplastics as they wear. Hull Pro is non-sacrificial — the coating does not ablate or shed particles into the water. What goes on stays on until you choose to remove it.
Less fuel, fewer emissions
Hull Pro's smooth surface reduces drag — engines work less hard at the same speed. Up to 20% fuel savings means fewer emissions per trip, season after season. Better for your wallet and the air above the water.
The problem with traditional bottom paint
Antifouling paint was designed to poison marine life. That is not an exaggeration.
Traditional copper-based antifouling paints work by continuously releasing toxic biocides into the water around your vessel. That is the mechanism — it is designed to kill. Here is what that means in practice.
Copper toxicity in the water column
Copper ions from antifouling paint accumulate in marina sediment and the water column. Studies have found copper concentrations in heavily trafficked marinas that exceed safe thresholds for aquatic life — harming fish, shellfish, and invertebrates that don't have a choice about where they live.
Copper-based antifouling paint is already banned or restricted on freshwater lakes in many US states for this reason.
Microplastic shedding
Ablative antifouling paints are designed to slowly erode — that erosion is what keeps fresh biocide continuously exposed. What that also means is that every season, microscopic paint particles shed directly into the water. Those particles do not disappear. They enter the food chain.
Hull Pro is non-sacrificial. It does not ablate. No particles, no shedding, no microplastics entering the water.
Sandblasting waste and chemical disposal
Removing old antifouling paint requires sandblasting — a process that generates copper-laden dust requiring careful containment and disposal as hazardous waste. Haul-out facilities that do this work are subject to strict EPA runoff regulations for good reason.
Removing Hull Pro requires sanding at 300 grit. Clean, straightforward, no hazardous waste classification.
Myth vs. Fact — Common misconceptions about biocide-free coatings
Biocides are necessary to prevent fouling in saltwater.
Biocides kill growth. Hull Pro makes growth easier to remove. The approach is different — not the result. Maintenance is still required in saltwater, but no toxic chemicals are needed to achieve it.
Eco-friendly coatings sacrifice performance.
Hull Pro's smooth ceramicized epoxy surface reduces drag — something antifouling paint physically cannot do. Up to 20% fuel savings and up to 15% speed increase are documented results. Traditional paint adds drag as it builds up over seasons.
Hull Pro is banned at green marinas because of its hardener.
Hull Pro's Part B hardener carries standard safety warnings common to all two-part epoxy systems. The applied, cured formula is classified as not a marine pollutant under international maritime law. If your marina has questions, we will speak to their harbormaster directly.
What the data actually says
Hull Pro's environmental credentials are documented. Not marketed.
Hull Pro is a two-part ceramicized epoxy — Part A base and Part B hardener, mixed at a 4:1 ratio. Every environmental claim we make is backed by the product's Safety Data Sheets, independently prepared according to USA Federal HAZCOM 2012 standards.
Part A is classified as non-hazardous under OSHA. No hand, skin, eye, or respiratory protection is required for Part A handling. Part B is a standard epoxy hardener — corrosive in unmixed form, as all two-part epoxy hardeners are, and classified as not a marine pollutant under international maritime shipping law.
Neither part contains Persistent, Bioaccumulative, or Toxic substances. Neither part contains substances regulated as pollutants under the Clean Water Act. The applied formula contains no biocides — by design, not by accident.
What the SDS confirms
Part A: Non-hazardous under OSHA HCS
No hand, skin, eye, or respiratory protection required. No hazardous substances at their given concentrations.
No PBT or vPvB substances in either part
Neither part contains Persistent, Bioaccumulative and Toxic substances — confirmed in both SDS documents.
Clean Water Act compliant — both parts
Neither part contains substances regulated as pollutants under the Clean Water Act Priority Toxic Pollutants list.
Part B: Not a marine pollutant under IMDG
Under International Maritime Dangerous Goods Code, Part B is classified as not a marine pollutant — the same standard used to regulate cargo shipped across international waters.
Low VOC — under 250 g/L
Well within EPA and state air quality thresholds. No respirator required for application in well-ventilated conditions.
No biocides in the applied formula
The cured Hull Pro coating contains no antimicrobial or antifouling biocides. 100% biocide-free is not a marketing claim — it is what the chemistry produces.
From the marine community
A scuba diver and marine media professional shares his perspective.
Gareth Bartlett works in marine media and dives regularly — he sees the underwater impact of bottom paint firsthand. In this reel, he explains why the industry shift toward biocide-free solutions matters, and why Hull Pro is the product he stands behind.
Gareth is not a sponsored athlete. He is a working marine media professional who chose to share Hull Pro because he believes in what it does for the water he dives in.
"If you own a boat, think about using Hull Pro. It's a sustainable alternative to traditional bottom paints — environmentally friendly."

A note on green marinas
Some green marinas don't yet recognize Hull Pro. Here is why — and what to do about it.
Hull Pro's Part B hardener carries standard safety warnings — corrosive in unmixed form, as all two-part epoxy hardeners are. Some marina staff see those warnings and flag the product without reviewing the full environmental profile of the applied, cured formula.
The applied Hull Pro coating is classified as not a marine pollutant. Neither part contains substances on the Clean Water Act's priority toxic pollutants list. If your marina has questions, we will provide full documentation and speak to their harbormaster directly.
