What is SEAJET 038 TAISHO and why choose it
SEAJET 038 TAISHO is a copper-free, super self-polishing antifouling coating designed for yachts and pleasure craft. Based on a unique high-activity hydrolysis polymer, it delivers outstanding antifouling performance even in high-fouling waters, ensuring effective, controlled release of active ingredients over time. It is suitable for all common marine substrates, including aluminium, when correctly primed.
This one-pack antifouling is easy to apply by brush, roller or (for professionals) spray, and is available in a wide colour range to match or contrast with existing hull finishes.
Main features

Drying and overcoating times (40 µm DFT)
- At 5 °C: surface dry 3 h; hard dry 6 h; minimum overcoating interval 8 h; no maximum; minimum time to launch 16 h.
- At 10 °C: surface dry 2 h; hard dry 5 h; minimum overcoating interval 7 h; no maximum; minimum time to launch 12 h.
- At 20 °C: surface dry 1 h; hard dry 4 h; minimum overcoating interval 6 h; no maximum; minimum time to launch 10 h.

Drying times and overcoating intervals increase with increasing film thickness. Before recoating, always ensure the existing film is fully dry throughout.
Substrates and primer systems
- Suitable substrates: suitably primed GRP, wood, steel, aluminium.
- Recommended primers:
- SEAJET 015 Underwater Primer.
- When applying directly over SEAJET 117, apply SEAJET 038 TAISHO within 48 hours.
- For aluminium (Spanish/combined data): SEAJET 017 followed by SEAJET 117 before SEAJET 038 TAISHO.
Applications and use cases
Typical applications
- Antifouling protection for yachts and recreational boats operating in high fouling areas.
- Use on hulls made from GRP, wood, steel or aluminium, when correctly prepared and primed.
- New builds or maintenance repaints over compatible existing antifouling systems.
Surface preparation
- On existing antifouling:
- High-pressure fresh water wash (approximately 200 bar) to remove fouling and salt.
- Remove any existing antifouling in poor condition.
- For antifouling in good condition, check SEAJET compatibility guidance before application.
- Ensure the surface is dry and free from salt, grease, oil or other contaminants; degrease if required.
- On GRP / steel:
- Sand with P100 abrasive paper, remove all dust and apply SEAJET 015 or SEAJET 117 as primer.
- On wood:
- Sand with P100 abrasive paper, remove dust and apply SEAJET 015.
- On aluminium:
- Sand with P100 abrasive paper, remove dust and apply SEAJET 017 followed by SEAJET 117 before SEAJET 038 TAISHO.
Application recommendations
- Stir thoroughly before use until the product is of a uniform consistency.
- Apply two full coats.
- Apply an additional coat on leading edges, waterline, rudders and stern gear for extra protection.
- Antifoulings should only be wet sanded or chemically stripped.
- Do not burn-off or dry sand old antifouling coatings.
- Values for film thickness and spreading rate are based on roller application; brush application may require more coats to achieve the specified thickness.
- After immersion, SEAJET 038 TAISHO may show a slight colour change; colour differences between batches may occur, so mix different batches together before use.
FAQ
1. On which substrates can SEAJET 038 TAISHO be used?
It can be used on suitably primed GRP, wood, steel and aluminium surfaces.
2. Is SEAJET 038 TAISHO copper-free?
Yes. It is a copper-free self-polishing antifouling based on a unique resin system.

Two coats are recommended, with an extra coat on leading edges, waterline, rudders and stern gear.
4. What is the recommended dry film thickness per coat?
The recommended dry film thickness is 40 µm per coat (approximately 100 µm wet).
5. How long can the boat stay ashore after application before launching?
The maximum immersion time after application is 3 months.
6. Can it be applied by spray?
Yes, SEAJET 038 TAISHO can be applied by spray, but spray application is for professional use only.
7. What thinner should be used?
Use SEAJET THINNER A, with thinning between 0 and 5% by volume if needed.
8. What are the drying times at 20 °C?
At 20 °C, the coating is surface dry in about 1 hour, hard dry in about 4 hours, can be overcoated after a minimum of 6 hours, and can be launched after 10 hours.
9. How should existing antifouling in poor condition be treated?
Existing antifouling in poor condition should be removed after high-pressure fresh water washing to eliminate fouling and salt.
10. Does colour variation occur?
Yes. Slight colour changes may occur after immersion, and colour differences between batches are possible; mix batches together before use to minimise variation.
