Once immersed, PropOne will work for a minimum of 1 year. After this point the coating will still be there but it will start to lose its effectiveness, continuing to work depending on local conditions and vessel usage.

Check out our PropOne Reviews Page and see for yourself!

PropOne is a two-coat system consisting of a Primer Coat and a Foul Release Coating (Clear Coat). The Clear Coat is a non-biocidal, super-slick coating which prevents organisms from strongly adhering to the surface of the propeller and all underwater fast-moving metals.

Organisms can be easily dislodged once the boat is placed in drive and there is sufficient water flow through the running gear.

The removal of the fouling organisms is purely a mechanical effect. The Clear Coat does not prevent marine growth by chemically poisoning the environment.

PropOne, being a foul release coating will last longer than antifoul, with minimal effort needed in the way of maintenance given its self-cleaning properties.

PropOne relies on its slick surface and the force of flowing water over this surface, meaning barnacles, tubeworms, weeds, slime, bryozoans, zebra mussels and other growth will struggle to stick onto your running gear! With bonus benefits like:

  • No build-up of copper or other toxic biocide residues can happen in marinas and harbours where the foul release is used.
  • Unlike biocidal antifouling paints, these coatings can be used in both fresh and saltwater as the physical properties and performance of the paint are not altered by variations in salinity.

Unlike some competitors’ foul release coatings, you are encouraged to apply PropOne™ yourself if you are familiar with application of similar products. To get the best results out of your PropOne kit we suggest you understand and follow our application guides and technical information.

Yes, PropOne was formerly known as PropGold.

Yes, you can re-apply PropOne to bare metal areas where PropOne has worn off due to regular use, such as the tips of the propeller blades.

Contact us at for more information on re-applying PropOne over an existing application.

All PropOne kits have a shelf life of 3 years from date of manufacture, with the date of expiry being clearly labelled on your kit.

PropOne can be applied to all underwater metallic surfaces:

  • Propellers
  • Propeller shafts
  • Prop struts
  • IPS drives
  • Rudders
  • Trim tabs
  • Bow & stern thrusters

You can also use our Underwater Light Coating (ULC) clear coat directly on underwater lights.

PropOne will remain just as effective even if the boat is left out of the water for extended periods of time and hauled out/launched repeatedly.

No maintenance required. Once the boat has been hauled out, avoid heavy abrasive cleaning like scraping and very high-pressure hosing. To remove lingering marine growth all that is needed is light wiping with a non-abrasive cloth and light pressure washing with water.

Allow for surface preparation, either using PropOne Silicone Remover and Paint Stripper or  80-120 grit mechanical grinder before you start painting as well as proper surface cleaning using our recommended surface preparation cleaner, Prop Wash and solvents.

This will be the majority of the time with the painting process being relatively quick.

Refer to brief application guide for more information on painting times

We suggest a minimum 12 hours drying time after the final coat for an average air temperature of 20°C (68°F) and minimum 16 hours drying for air temperatures of 10°C (50°F). Lower temperatures or humidity will extend cure time.

Minimum time to immersion at 55% RH:
20°C (68°F): 12 hours
10°C (50°F): 16 hours
Lower temperatures or humidity will extend cure time. Minimum application conditions: 10°C (50°F), 55% RH.

Ensure that rain or other water-splashes do not contact the surface of PropOne while it is drying.

PropOne can be used in fresh or saltwater as it is a foul release, not an anti-foul. The coating surface is not altered by variations in salinity. PropOne relies on a slick surface and flowing water over this surface, meaning Zebra mussels and other freshwater growth will struggle to stick onto your running gear!

When it is time to renew, the old PropOne clear coat and primer must be removed before re-applying.

For this we have a Silicone Remover and a Paint Stripper available to remove the clear coat and primer coat. However, you may opt to use a mechanical grinder for this also. Once removed, normal application can proceed.

See brief application guide for more information

We always recommend using Prop Wash before acetone to ensure the metals are cleaned with an acid based solution to draw out any contaminants.

Acetone, whilst being a good cleaner and helps to dry the metal, can often leave contaminants inside the porous metal, which could affect adhesion.

If you do clean with Prop Wash after acetone, you will see your rag turn black and the metals are much brighter.

Apply 2 thin coats of primer, as it is a very thin coating. The Clear Coat is much thicker and you only need to apply 1 generous coat.

The surface is touch dry at the point when a gloved finger is lightly touched against the paint surface and no mark is made in the paint nor is paint transferred to the glove.

In the specific case of PropOne primer, when brushing one coat over another, if the coat underneath is marked by the brushstroke, it isn’t touch dry.

Touch dry for the primer is the point at which the coating loses its “shine”.

Typically this overcoating window lasts anywhere between 3-10 minutes depending on the temperature.
