Will antifouling paint still be relevant in 2025?

Is antifouling paint for boats worth it in 2025?

Antifouling paint is a common term for antifouling paint containing biocides. In 2025, the choice will be made based on effectiveness, overall cost, and responsibility – and according to the significantly tightened conditions set by Tukes in Finland.

Make the right decision quickly

Save money and time: choose a solution that minimizes friction, wash cycles, and unnecessary work steps.
Stay on the right side of regulation: our guidelines comply with Tukes policies – no room for interpretation.
Choose smartly for the conditions: foul-release, epoxy + washing, or approved antifouling – we clearly explain when each works.
Get the job done right the first time: step-by-step instructions and checklists reduce errors and rework.

Strategic Perspective – Efficiency, Cost, Responsibility

Efficiency: a clean hull reduces friction → lower consumption, better range.
Overall Cost: paint vs. maintenance interval, washing and lifting infrastructure, seasonal work – often a biocide-free model is more cost-effective overall.
Responsibility & Regulation: In Finland, the use of biocidal antifouling is restricted; for many boaters, biocide-free AFS + planned maintenance is the recommended primary path. (helcom.fi)

Alternatives to antifouling paint 2025

ALTERNATIVE	PROS	CONS
Silicone-based fouling release	Very low friction; often performance equal to or better than copper paint; biocide-free	Higher initial cost; requires careful preparation
Hard epoxy + regular washing	Durable, long lifespan; chemical-free during use season	Requires washing/lifting infrastructure during the season
Copper-free antifouling	Lower environmental impact	Effectiveness varies by region, needs practical monitoring
Ultrasonic system	Chemical-free; continuous prevention	Investment; varying results depending on hull shape
Trailering/Dry storage	No coating chemicals; quick spring launch	Requires logistics/space

Rationale: HELCOM recommends biocide-free AFS solutions for areas with low fouling pressure, and scientific evidence supports the effectiveness and lower toxicity of silicone coatings.

How to choose – 5-point quick guide

Water Area: inland waters → no antifouling paint. On the coast, assess local fouling pressure (harbor, current, salinity).
Usage Profile: frequent use → fouling release works excellently due to movement; harbor-intensive use → epoxy + washing or considered antifouling.
Maintenance Readiness: can 1–2 washes be done during the season? If yes, a biocide-free solution is often the most cost-effective overall.
Hull Material: ensure system compatibility (aluminum/steel/wood/laminate).
Regulation: if you opt for antifouling paint, verify the copper leaching limit, use in marine areas, and other Tukes requirements.

Practical guide – if you choose antifouling paint

Pre-treatment: degreasing → wet sanding → dust control → correct primer.
Application: follow manufacturer's recoating intervals and drying times; film thickness is crucial.
Safety & Environment: consumers should not spray paint; wear protective gloves; do not wash in the sea with boat washers; do not release wastewater into the environment.

Practical solutions for your boat

Next, we break down the most common questions into practice: when is antifouling paint sensible, how to choose correctly, which mistakes to avoid, how to do the job, and how to transition smoothly to a new surface.

Antifouling paint: when is it sensible in 2025?

If you operate in marine areas and the fouling pressure is clearly high, and washing/lifting facilities are not available, biocidal antifouling may be justified. However, remember Finland's usage restrictions and first consider a biocide-free alternative.

Antifouling paint removal – a safe and clean transition to a new surface

Remove if the surface is flaking, incompatible, or if you are switching to a biocide-free system. Methods: wet scraping, sanding with dust control, chemical stripper; blasting only by a professional.

Frequently Asked Questions (FAQ)

Is the use of antifouling paint permitted everywhere?
No. Its use is prohibited in inland waters; allowed only in marine areas and for boats >7m under Tukes conditions.

Can I wash an antifouled hull in the sea?
No. Washing in sea boat washers is prohibited, and untreated wash waters must not be released into the environment.

Does silicone coating really work?
Yes. Reviews and field tests show that silicone is in many places more effective than copper-based paint for leisure boats – without biocides.

Why is the trend towards non-toxic solutions?
Boaters' environmental awareness has increased. Additionally, HELCOM's 2025 guidelines emphasize biocide-avoiding AFS systems where practically possible (e.g., low fouling pressure areas).
