What is SEAJET 034 EMPEROR A and why choose it
SEAJET 034 EMPEROR A is a high performance, self polishing antifouling coating designed for use on aluminium hulls and other suitably primed substrates. It is ideal for club racing and performance sailing, as it can be burnished during the season to achieve a smoother finish. Available in bright colours and in small pack sizes, it is suitable for use over GRP, wood, steel and aluminium when correctly primed.

Drying and overcoating times (at 56 µm DFT)
- 5°C: Surface dry 3 h; hard dry 12 h; minimum overcoating interval 12 h; maximum none; minimum time before launch 24 h.
- 10°C: Surface dry 2 h; hard dry 8 h; minimum overcoating interval 8 h; maximum none; minimum time before launch 18 h.
- 20°C: Surface dry 1 h; hard dry 5 h; minimum overcoating interval 5 h; maximum none; minimum time before launch 12 h.
- 30°C: Surface dry 30 min; hard dry 4 h; minimum overcoating interval 4 h; maximum none; minimum time before launch 10 h.
Drying times and overcoating intervals will increase if a higher film thickness is applied. Before recoating, ensure that the existing paint film is completely dry.
Storage, shelf life and disposal
- Storage conditions: Store in a dry, cool and well ventilated space, away from direct sunlight. Containers must be kept firmly closed. Handle with care.
- Shelf life: Minimum 2 years at 20°C.
- Disposal: Do not empty into drains. Dispose of this material and its container at a hazardous or special waste collection point.
Applications and use cases
- Club racing and regattas: The self polishing mechanism and the possibility of burnishing during the season make it suitable for performance-oriented sailing.
- Aluminium hulls: Specifically indicated as suitable for aluminium when correctly primed.
- GRP, wood and steel boats: Can be applied over these substrates when used in combination with the recommended SEAJET primers.
- New builds and maintenance: Appropriate both for new applications on properly prepared substrates and for maintenance over compatible existing antifoulings.
Surface preparation and application overview
Over existing antifouling
- Clean the surface with fresh water using high pressure (approximately 200 bar) to remove fouling and salts.
- Remove any loose or poorly adhering antifouling.
- If the existing antifouling is in good condition, check the SEAJET antifouling compatibility table. If compatible, apply SEAJET 034 EMPEROR A directly.
- If the existing antifouling is not compatible or its type is unknown, apply one coat of SEAJET 015 UNDERWATER PRIMER before SEAJET 034 EMPEROR A.
- Antifouling should only be wet sanded. Never burn-off with heat or dry sand old antifouling.
- Ensure the surface is dry and free from contaminants such as salt, grease or oil. Degrease if necessary.
- Apply two coats, plus an extra coat on leading edges, waterline, rudder and stern gear.
New application on different substrates
- Wood: Sand with P100 abrasive paper, remove all dust and apply 2 coats of SEAJET 015 UNDERWATER PRIMER.
- Polyester (GRP): Sand with P100 abrasive paper, remove all dust and apply 2 coats of SEAJET 117 MULTIPURPOSE EPOXY PRIMER.
- Steel: Sand with P100 abrasive paper, remove all dust and apply 3 coats of SEAJET 117 MULTIPURPOSE EPOXY PRIMER.
- Aluminium: Sand with P100 abrasive paper, remove all dust and apply 4 coats of SEAJET 117 MULTIPURPOSE EPOXY PRIMER.
Before use, stir SEAJET 034 EMPEROR A thoroughly until a uniform mixture is obtained. Film thickness and spreading rate depend on the application method; when using a brush, additional coats may be required to reach the specified dry film thickness. Values are based on roller application.
The maximum time the coated hull can remain in the air before immersion is 6 months. After immersion, a slight colour change may occur. Colour differences between batches are possible; mix different batches together before use.
FAQ – SEAJET 034 EMPEROR A
-
On which substrates can SEAJET 034 EMPEROR A be used?
It is suitable for use on properly primed polyester (GRP), wood, steel and aluminium.
-
Which primers should be used before applying this antifouling?
Use SEAJET 015 UNDERWATER PRIMER or SEAJET 117 MULTIPURPOSE EPOXY PRIMER, following the substrate-specific preparation instructions.
-
How many coats are recommended?
Apply two coats, with an additional coat on leading edges, waterline, rudder and stern gear. When using a brush, extra coats may be needed to achieve the specified film thickness.
-
What is the recommended dry film thickness per coat?
The recommended dry film thickness is 56 µm per coat (100 µm wet film thickness).
-
How long after painting can the boat be launched?
Depending on temperature, minimum times before launch are approximately 24 h at 5°C, 18 h at 10°C, 12 h at 20°C and 10 h at 30°C.
-
What is the maximum time the hull can stay ashore after painting?
The maximum immersion time after application is 6 months.
-
Can existing antifouling be overcoated directly?
If the existing antifouling is in good condition and compatible according to the SEAJET compatibility table, it can be overcoated after proper cleaning. If compatibility is unknown or negative, first apply SEAJET 015 UNDERWATER PRIMER.
-
How should old antifouling be removed?
Old antifouling should only be wet sanded or chemically stripped. Never use heat or dry sanding for removal.
-
What pack sizes are available?
The product is supplied in 0.75 l and 2.5 l containers.
-
Does colour variation occur?
Yes, slight colour changes can occur after immersion and colour differences between batches are possible. Mix different batches before use to minimise visible variation.
