What is PropOne Primer and why choose it
PropOne Primer is the anti-corrosive base coat of the PropOne two-coat system, designed for use on propellers and fast-moving underwater running gear. It is applied as a thin, solvent-borne primer that prepares and protects ferrous and non-ferrous marine alloys, including aluminium, before application of the PropOne Clear Coat foul release layer. When correctly mixed with its Primer Activator and applied over properly prepared metal, it contributes to durable adhesion and corrosion protection under continuous immersion.
Main features
- Part of a dedicated two-coat PropOne system (Primer Coat + Clear Coat).
- Anti-corrosive primer for propellers and running gear permanently immersed in water.
- Compatible with ferrous and non-ferrous marine alloys, including aluminium.
- Designed for use with a non-biocidal foul release Clear Coat that prevents strong adhesion of organisms.
- Helps ensure marine growth can be mechanically removed once the vessel is driven.
- Applied in two thin coats by brush or roller for complete coverage.
- Mixing ratio with Primer Activator: 4 parts Primer Coat to 1 part Primer Activator (by volume).
- Pot life of mixed primer: 4 hours at 25°C (77°F).
- Minimum application temperature: 5°C (40°F).
- Time to immersion (with Clear Coat applied) at 55% RH: 16 hours at 10°C (50°F), 12 hours at 20°C (68°F).
- Not suitable for aquaculture applications and must not be applied to anodes.

System and application conditions
- Mixing ratio (by volume): 4 parts Primer Coat to 1 part Primer Activator.
- VOC of mixed primer: 687 g/L.
- Recommended storage temperature: between 5°C and 27°C (40°F–80°F).
- Minimum application temperature: 5°C (40°F).
- Minimum application conditions for time to immersion data: 10°C (50°F), 55% RH.
- Pot life of mixed primer at 25°C (77°F): 4 hours.
Applications and use cases
- Anti-corrosive primer for propellers permanently immersed in water.
- Primer for fast-moving underwater running gear such as rudders, propeller shaft struts and trim tabs.
- Suitable for all ferrous and non-ferrous marine alloys, including aluminium.
- Used where a non-biocidal foul release solution is required, since the associated Clear Coat does not prevent marine growth by chemically poisoning the environment and fouling removal is purely mechanical when the vessel is driven.
- Not to be used in aquaculture applications.
- Must not be applied to anodes.
FAQ
1. What is PropOne Primer used for?
PropOne Primer is the anti-corrosive base coat in the PropOne system for protecting propellers and underwater running gear before applying the foul release Clear Coat.
2. On which materials can PropOne Primer be applied?
It is suitable for use on all ferrous and non-ferrous marine alloys, including aluminium.
3. How should the surface be prepared before applying the primer?
The surface must be thoroughly cleaned of marine growth, old coatings, rust and corrosion using brushing, abrasion or scraping, followed by cleaning with Prop Wash Wipes, rinsing with fresh water and wiping with acetone before coating.
4. What is the correct mixing ratio for PropOne Primer and Activator?
Mix 4 parts Primer Coat with 1 part Primer Activator by volume. One whole bottle of Activator is added to one whole can of Primer.
5. How many coats of PropOne Primer are required?
Two thin coats of Primer are required, applied sparingly by brush or roller, allowing the first coat to become touch-dry before applying the second.
6. How soon should the Clear Coat be applied after the primer?
The Clear Coat should be applied as soon as the Primer coating is touch dry.
7. What is the pot life of the mixed primer?
The pot life of mixed PropOne Primer at 25°C (77°F) is 4 hours.
8. Can PropOne Primer be used in aquaculture or on anodes?
No, it is not suitable for use in aquaculture applications and should not be applied to anodes.
