What SEAJET 122 BRILLIANCE is and why choose it
SEAJET 122 BRILLIANCE is a high performance, one-component urethane alkyd topcoat designed as the final finishing layer above the waterline. It delivers a high gloss, durable surface with excellent colour retention and resistance to minor knocks and scratches. Developed primarily for brush application, it provides a smooth, long‑lasting finish on suitably primed GRP, wood and steel, and can also be applied directly to fibreglass.

Applications and use cases
- Final topcoat for yachts and boats above the waterline: Provides a high gloss, durable finish with excellent colour retention on topsides and superstructures.
- Interior and exterior marine surfaces: Suitable for use on appropriately primed GRP, wood and steel components where a glossy, impact‑resistant finish is required.
- Refurbishment of existing coatings: Can be applied over existing paint in good condition after proper cleaning and sanding.
- Direct application to fibreglass: Ideal for GRP hulls and structures where a primer is not required, or in combination with SEAJET 012 UNIVERSAL PRIMER/UNDERCOAT for more even colour.
Surface preparation guidelines
- Surfaces in poor condition: Remove old paint layers by sanding or stripping.
- Existing paint in good condition or GRP/fibreglass:
- Clean the surface thoroughly.
- Wash down with fresh water and allow to dry.
- Flatten back with P180–P280 abrasive paper.
- Clean the surface with a tack rag.
- Wood, steel and aluminium: Must be primed with appropriate primers before applying SEAJET 122 BRILLIANCE.
- Number of coats: Apply a minimum of two coats of SEAJET 122 BRILLIANCE TOPCOAT.
- Between coats: Sand with P400 or finer abrasive paper.
Application recommendations
- Product is developed for application by brush. Use a soft, long‑haired, good quality brush.
- Roller application is possible, but the paint film must be brushed out to achieve a smooth finish.
- Avoid applying the final coat when the surface is damp or in direct sunlight. Dry mornings are recommended.
FAQ
-
Is SEAJET 122 BRILLIANCE a one‑component or two‑component product?
SEAJET 122 BRILLIANCE is a one‑component urethane alkyd topcoat supplied ready for use after thorough stirring.
-
Which substrates can I paint with SEAJET 122 BRILLIANCE?
It is suitable for suitably primed GRP (fibreglass), wood and steel, and for aluminium when primed with appropriate primers. It can also be applied directly to fibreglass.
-
Do I need a primer before applying this topcoat?
On wood, steel and aluminium, a suitable primer is required. On fibreglass/GRP you may apply SEAJET 122 BRILLIANCE directly or use SEAJET 012 UNIVERSAL PRIMER/UNDERCOAT to achieve a more even colour.
-
How many coats are recommended?
A minimum of two coats of SEAJET 122 BRILLIANCE TOPCOAT is recommended.
-
What is the theoretical coverage per litre?
The theoretical spreading rate is approximately 15.7 m² per litre at around 35 µm dry film thickness, depending on application method and conditions.
-
How long does the paint take to dry?
At 20°C and 35 µm DFT, the coating is surface dry after about 1 hour and hard dry after 24 hours.
-
When can I recoat with another layer?
At 20°C, the minimum overcoating interval is 24 hours and there is no stated maximum. If the maximum practical interval is exceeded, sand with wet or dry P320 abrasive paper before recoating.
-
Can I spray SEAJET 122 BRILLIANCE?
Yes. Airless spray is possible using a 0.011"–0.013" nozzle tip, 80–100 bar pressure and 5–10% thinning by volume with SEAJET THINNER U.
-
In what temperature and humidity range should I apply this product?
Apply between 5°C and 35°C ambient and product temperature, with substrate temperature between 7°C and 35°C and maximum relative humidity of 85%.
