01 — Why Nexus Marine

Official SEALS applicator in the Mediterranean.

« You don't buy a product. You buy an installation method. »

Nexus Marine is officially certified as a SEALS applicator for the Mediterranean territory. This certification matters: the product chemistry accounts for roughly 30 % of the final result. The remaining 70 % is determined entirely by the precision and discipline of the application protocol. Certification is not a commercial label — it is a technical requirement that governs every step from surface preparation to final quality control.

02 — The technology

Born from spacecraft. Patented for your boat.

SEALS is the world's first nano-diamond shielding technology designed specifically for boats. Derived from revolutionary spacecraft technology. Patented PHPS polymer — the world's hardest polymer applied to marine protection. Traditional ceramic coatings simply can't compete.

  • Nano-diamondFirst nano-diamond shielding technology in the world designed for boats.
  • Patented PHPSHardest polymer on the market — true 9H hardness.
  • Fast polymerizationImmediate protection, faster curing. Quick application and turnaround.
  • Hydro & oleophobicWater and oil slide off. Assisted anti-fouling, dirt no longer sticks.
  • Eco-friendlyReduces water use and eliminates aggressive cleaning chemicals.
SEALS hydrophobic effect — water and oil slide off the protected surface

The principle : high contact angle = hydrophobic surface = simpler maintenance.

03 — The range

9 products, 9 surfaces, 1 protocol.

SEALS is not a single product — it is a modular system of 9 patented formulations, each dedicated to a specific substrate. Nexus Marine maps your boat zone by zone during the initial audit and selects the right product for each surface.

SEALS range — SILKWALK, ONESHIELD, TRISHIELD, RENEW, PUREGLAS, ZEROOX, FLEXIX, POWERLUX, LUXINT
  • SILKWALK Deck — gelcoat & plexiglass. Hydrophobic, oleophobic, silky shine, UV and saline resistance.
  • ONESHIELD Hull walls (when aground) — carbon nanotubes + nanodiamonds. Elasticity + resistance + anti-fender abrasion.
  • TRISHIELD 1·2·3 Hull walls 3-step pro treatment — porosity near-zero, ×1000 resistance, UV-A/UV-B, self-cleaning under sail.
  • PUREGLAS Glass & ceramics — anti-limescale, anti-trace, anti-salt deposit. Visibility preserved.
  • ZEROOX Stainless & metals — microscopic anti-oxidation film. No more steel polishing chores.
  • FLEXIX Hypalon, PVC, sails, tender, wrapping — transparent barrier on flexible surfaces, no alteration of shine or colour.
  • POWERLUX Engines, hot surfaces, induction hobs — barrier against grease, liquids and cooking residues.
  • LUXINT Interiors — furniture, tables, leather. Microfibre cleaning, no aggressive detergents needed.
  • RENEW Refresh — extends all SEALS treatments between full applications. Express application.

+ CLERABOAT and CLERAGLAS — surface preparation products used by our team before every application.

The official SEALS protocol

Three steps. That's it.

The SEALS process is intentionally simple — that's what makes the application so fast. The complexity is in the chemistry, not in the gesture.

01

PREP

Deep cleaning of the surface with CLERABOAT or CLERAGLAS. Essential preparation for the molecular adhesion of the nano-diamond.

02

SHIELD

Application of the right SEALS product in a single pass. Fast polymerization. The surface instantly feels silky to the touch.

03

SAIL

Just sail. With SEALS, you minimize maintenance and cleaning — more time to fully enjoy your boat and the pleasure of sailing.

"Clean less. Sail more."

05 — Before / After

You can see it with the naked eye.

Real photos from SEALS projects applied by Nexus Marine. SEALS has been tested on Lagoon catamarans, Beneteau sailboats, Sanlorenzo luxury yachts.

Hull

Yacht hull before and after SEALS treatment — side-by-side comparison

Same yacht. Same angle. Same Mediterranean exposure. The SEALS-treated surface shows what happens when soiling and oxidation can no longer find purchase on the substrate — the hull stays cleaner between cycles, and cleaning takes a fraction of the usual effort.

Stainless steel gloss & finish

Yacht stainless steel before and after SEALS — mirror effect, lasting shine

Without treatment, marine stainless tarnishes, pits and loses its shine under salt and UV exposure. With a SEALS protocol applied by Nexus Marine, handrails, pulpits and deck hardware regain a lasting mirror finish — no abrasive polishing, no mechanical refinishing.

Glazing

Yacht glazing before and after PureGlas — hydrophobic effect droplets

PureGlas creates a hydrophobic surface on portlights, windshields and helm station glazing. Droplets slide off immediately rather than spreading and drying as mineral deposits. Limescale adhesion is dramatically reduced; gloss retention extends to 12 to 18 months under Mediterranean exposure.

06 — The journal

Four truths to know before you treat your yacht.

What product datasheets won't tell you. Four angles every owner, captain or broker should understand before signing a quote.

Myth busted

« Nano-coatings are too expensive. »

The cheapest option in year one is almost always the most expensive over ten years.

Year 1 Year 10 Gelcoat Gelcoat Traditional maintenance SEALS Nexus Marine protocol

On a 20 m yacht, conventional maintenance accumulates annual polishing, aggressive treatments and — every 5 to 7 years — a partial or full gel-coat replacement. With every cycle, the gel-coat thins. With every sand-back, the vessel's value erodes.

  • Annual manual polishing: €2,500 to €5,000 per season
  • Mid-life gel-coat replacement: €25,000 to €60,000 depending on size
  • Vessel finish slowly written off the books

The SEALS protocol does the opposite: a controlled investment in year one, a stable annual refresh cost and a hull that no longer thins or dulls.

Over 10 years, the cumulative cost gap can exceed €80,000 in favour of SEALS — before counting preserved resale value.

Seasonal angle

Be the first yacht ready for the season.

While others burn crew hours in March, you're already underway.

Spring prep is when every captain counts hours. Stripping winter deposits, aggressive polishing, chemical treatment of pitted stainless, teak finishing. Thirty to fifty crew hours per vessel — sometimes more.

With a SEALS protocol applied the previous autumn and a winter refresh scheduled, the equation changes radically.

  • Express application planned at de-winterisation
  • 1 to 2 h drying — ready for water the same day
  • Surfaces clean from the first soft wash
  • Zero aggressive chemistry needed for re-launch

The result: a vessel operational in 48 h while your competitors lose a week. On a Mediterranean season starting late April, those days are worth gold.

Be sailing while your neighbours are still polishing their handrails.

Blind spot

The tender. The piece everyone forgets.

Flexible surface, maximum exposure, wrong products. The tender is the fleet's blind spot.

Tenders, jet-skis, paddles, bimini covers, fenders: these flexible surfaces take UV wear and salt at full load. Yet nearly every conventional ceramic product cracks or peels on materials that flex.

The result on most yachts: faded colour, dull surface, salt marks that never fully come off after 18 months. And a replacement cost that comes back identical every cycle.

  • SEALS Flexix engineered for flexible surfaces
  • No cracking, no peeling
  • Fast low-pressure airbrush application
  • Compatible with composite, hypalon, vinyl, sails

Nexus Marine treats your tender, jet-skis, paddles and sails under the same protocol as the hull. An integrated fleet logic that few applicators offer.

A consistent fleet is also what your guests see from the tender.

The trade secret

70 % of the result happens before the coating.

The world's best product on a poorly prepared surface — zero result.

The science behind SEALS is simple: nano-diamond technology and the patented PHPS polymer seal surfaces at the molecular level. But to penetrate properly, the substrate has to be impeccably prepared with CLERABOAT or CLERAGLAS. No contamination, no residual film, no untreated micro-scratches.

This is precisely the step amateur or rushed applicators skip — and precisely the step that determines whether the coating lasts 18 months or 6.

  • Gentle biodegradable chemical decontamination
  • Solvent degreasing matched to the substrate
  • Selective micro-polishing of scratched zones
  • Hygrometric control before application

The Nexus Marine method never shortens these steps. Not even when the client is in a hurry. That's the difference between a certified applicator and a generic operator.

Our real craft is everything we do before we put the SEALS on.

07 — Who it's for

For owners. Captains. Fleet managers. Brokers.

The same coating system, a different measurable benefit depending on where you sit in the chain.

Owners

Your yacht is a capital asset operating in a corrosive environment. SEALS protects its long-term value without exposing the vessel to the harsh oxidizing chemistry conventional maintenance depends on. Buyers notice the condition difference immediately.

Captains & chief engineers

Crew hours recovered from routine surface maintenance are crew hours available for seamanship, guest service and safety. Aggressive cleaning chemistry disappears from the lockers — reducing crew health exposure and environmental compliance risk.

Fleet & charter managers

More operated days per vessel per year. Reduced unplanned downtime. Faster turnaround between charters. Quarterly fleet KPI reporting that gives you an actual maintenance dashboard. That is margin recovered on every unit in the fleet.

Brokers & charter agencies

A SEALS-protocol vessel comes to market with a professional photographic dossier, a completed valuation survey, and a documented maintenance record. Better-presented vessels command better asking prices. Clear referral commission structure.

08 — The Nexus Marine protocol

The product does 30 %. We do the other 70 %.

SEALS chemistry is exceptional. But a PHPS nano-coating applied to an under-prepared surface underperforms — and the owner never knows why. The Nexus Marine protocol closes that gap. Five locked steps, trained pairs, monitored conditions.

  1. 1
    Surface audit & custom mappingZone-by-zone inspection of every surface. Product selection confirmed at this stage, not assumed in advance. A detailed mapping document is shared with the owner or captain.
  2. 2
    PreparationDecontamination, degreasing and micro-polishing to the specification required by each surface type. This step determines adhesion quality. It cannot be shortened.
  3. 3
    Single-pass applicationMicrofibre cloth, certified pair, humidity continuously monitored. One single pass per surface. Immediate polymerization — the surface becomes silky to the touch from application.
  4. 4
    Zone-by-zone QCQC inspection completed zone by zone before the vessel is signed off. Maintenance log handed to the crew with all product references and application dates recorded.
  5. 5
    Scheduled annual refreshRefresh date, scope and pricing locked at installation. No need to renegotiate next season. Continuous, predictable protection cycle.
