Applications and use cases
- Decorative woodwork: Ideal as the clear base component in the Seajet 130 system for high-gloss finishes on quality interior and exterior joinery.
- Marine and yachting wood surfaces: Suitable for wooden parts where a durable, UV-resistant gloss varnish is required when mixed and applied as the complete Seajet 130 Polyurethane Gloss Varnish system.
- High wear zones: Recommended for wood surfaces exposed to abrasion and regular handling, thanks to its hard, chemically resistant film once fully cured.
- Professional workshops and yards: Compatible with airspray, brush and roller application, fitting varied professional application setups.
Surface preparation and application guidance
Surface preparation
- Surfaces in poor condition: Remove old varnish layers by sanding or stripping.
- Existing two-component varnish in good condition: Clean the surface thoroughly.
- Wood: Sand along the grain with P60–P80 abrasive paper, then sand again with P100–P220. Remove dust with a tack rag.
Application of the system
- Apply a minimum of five coats of SEAJET 130 Polyurethane Gloss Varnish (mixed base and hardener).
- For the first two coats add 10–15 % SEAJET THINNER P. For subsequent coats reduce to 0–10 % thinner.
- Sand between coats with P280–P400 abrasive for a smoother finish, followed by careful cleaning with a tack rag.
- Apply using a good quality bristle brush. For roller application, use a short-hair mohair or foam roller suitable for polyurethanes, then brush out with a soft long-haired brush to level the film.
- Avoid application when damp or in direct sunlight. Dry mornings under stable conditions are recommended.
FAQ
How many components does SEAJET 130 POLYURETHANE GLOSS VARNISH BASE have?
It is the base component of a two-pack polyurethane system and must be mixed with the specified hardener before use.
What is the correct mixing ratio?
The recommended mixing ratio is 67 parts base to 33 parts hardener by volume. Mix thoroughly and stir well before application.
Which thinner should I use?
Use SEAJET THINNER P. For airspray applications a thinning level of 0–10 % by volume is typical, depending on temperature and application conditions.
Can I apply it by brush or roller?
Yes. The product can be applied by brush, roller or airspray. When brushing or rolling, additional coats may be needed to reach the specified dry film thickness.
How many coats are recommended?
The technical literature recommends applying a minimum of five coats of the mixed Seajet 130 Polyurethane Gloss Varnish system for best durability and gloss build.
What are the ideal application conditions?
Apply between 5°C and 35°C ambient temperature, with product and substrate also within their specified temperature ranges, and at relative humidity up to 80 % RH. Avoid damp conditions and direct sunlight.
How long does it take to dry?
At 20°C and 30 µm DFT, the system is typically surface dry in about 2 hours and hard dry in about 8 hours. Overcoating is usually possible after 24 hours.

Section 8. Personal protection measures
The following personal protective measures are highlighted in the safety documentation for SEAJET 130 POLYURETHANE GLOSS VARNISH BASE:
- General ventilation: Provide adequate local exhaust ventilation and general extraction to keep vapour and particulate concentrations below occupational exposure limits.
- Respiratory protection: If exposure may exceed limits, use a respirator to EN 140 fitted with a combined particulate and vapour filter to EN 14387, with an assigned protection factor of at least 10 (for example, A2P3). During spraying in enclosed booths, a compressed air-fed respirator may be required until vapour and particulate levels are below limits.
- Hand protection: Use chemical resistant gloves tested to EN 374. Nitrile gloves provide good protection for spray application. Viton gloves are recommended for intense solvent contact (for example, immersion). Inspect and replace gloves regularly if damaged. PE under-gloves may be used in difficult situations such as high exposure or unknown chemical composition.
- Eye and face protection: Wear safety eyewear to EN 166 designed to protect against liquid splashes.
- Skin and body protection: Wear anti-static protective clothing made from natural fibre or high temperature resistant synthetic fibre. Avoid solvent-soaked clothing; change contaminated garments promptly.
- Hygiene measures: Smoking, eating and drinking should be prohibited in the application area. Wash hands and exposed skin thoroughly after use and before breaks. Do not use solvents or thinners to clean skin.
- Environmental precautions: Prevent product and cleaning residues from entering drains or watercourses.
