What is Epifanes PU Speedcoat and why choose it?
Epifanes PU Speedcoat is a professional two-component, chemically drying polyurethane topcoat designed exclusively for spray application. Based on an acrylic poly-ol resin, it delivers an extremely high-gloss finish with outstanding flow, very short overcoating times and long-lasting gloss retention. Once fully cured, the surface is scratch resistant, weather resistant and polishable, making it suitable as a durable protecting finish for both interior and exterior areas on properly primed substrates.
The system is intended for professional sprayers who require a fast-drying, high-build topcoat with excellent appearance on FRP, steel, aluminum and plywood constructions.
Main features
- Two-component polyurethane topcoat (Component A + Component B).
- Dedicated to spray application only (conventional air, HVLP and RP spray guns).
- Extremely high gloss with very good flow and leveling.
- Fast overcoating: short recoating and dust-dry times at standard temperatures.
- Long-term gloss retention with scratch and weather resistance.
- Polishable after full cure (approx. 7 days at 68°F / 20°C).
- Usable on FRP, steel, aluminum and plywood in combination with suitable Epifanes epoxy and polyurethane primers.
- Available in Epifanes colours, maritime-related colours and RAL colours on request.

Drying and pot life (1 mil dry film, 65 % R.H.)
| Temperature | Dust dry | Recoatable | Sandable | Pot life after mixing |
| 59°F (15°C) | 1.5 hours | 2 hours | 30 hours | 4 hours |
| 68°F (20°C) | 1 hour | 1 hour | 24 hours | 3 hours |
| 77°F (25°C) | 1 hour | 1 hour | 20 hours | 1.5 hours |
Note: Higher wet film thicknesses and/or limited ventilation will extend drying times, especially on horizontal surfaces.
Applications and use cases
- Yacht and boat topsides and superstructures on FRP, steel or aluminum using appropriate Epifanes primers.
- Metal structures (steel and aluminum) requiring a high-gloss, durable spray finish in professional environments.
- Plywood and wooden components that have been correctly primed with compatible Epifanes epoxy and polyurethane primers.
- Interior and exterior protection where high gloss, fast throughput and polishability are required.
For additional gloss and depth, one or more coats of Epifanes PU Speedcoat Clear Gloss may be sprayed over Epifanes PU Speedcoat Colour. This is also recommended if the surface will be polished.
Wet-on-wet application is possible when the solvents of the previous coat have evaporated (typically 60–90 minutes at 68°F / 20°C). If the subsequent coat is applied after more than 48 hours at 68°F, sanding is required.
FAQ – Epifanes PU Speedcoat
1. Can PU Speedcoat be applied by brush or roller?
No. This product is formulated solely for spray application and is not suitable for brush or roller use.
2. On which substrates can I use PU Speedcoat?
It can be used on FRP, steel, aluminum and plywood, always in combination with the correct Epifanes epoxy and polyurethane priming system or intact compatible two-component coatings.
3. How many coats are recommended?
A minimum of three spray coats is recommended to achieve a total dry film thickness of approximately 3.5–4.5 mil.
4. When can I polish the finish?
The coating can be polished after approximately one week at 68°F (20°C).
5. What are the ideal application conditions?
Apply between 59–86°F (15–30°C) with 50–75 % relative humidity in a well-ventilated area, avoiding major temperature differences between product, substrate and environment.
6. How long is the pot life after mixing?
Pot life depends on temperature: about 4 hours at 59°F, 3 hours at 68°F and 1.5 hours at 77°F.
7. What is the theoretical coverage?
Approximately 130 ft² per kg at 1 mil dry film thickness, depending on application technique and substrate shape.
8. Do I need to sand between coats?
Intercoat sanding is not required for wet-on-wet application. If the overcoating interval exceeds 48 hours at 68°F, sanding is necessary before applying the next coat.
