PropOne FAQs

Does PropOne work?

Yes it works! PropOne is applied to thousands of vessels every year, all around the world.

Since 2012 PropOne has earned a reputation for outstanding performance, worldwide support/customer service and unbeatable value for money.

How long will PropOne keep working for?

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.

How does PropOne work?

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.

Can I apply it myself or do you have to be a licensed applicator to buy it?

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.

How is PropOne different from antifoul?

The Clear coat of the PropOne system has an ultra-slick surface that marine growth struggles to stick to. PropOne Clear Coat contains no copper, tin or any other biocides or toxic substances harmful to marine life and it is designed specifically with a long service life in mind when applied to underwater running gear.

In contrast, antifoul paints release chemically poisonous materials to kill marine growth.

What is the shelf life of PropOne?

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.

What can be coated with PropOne under my boat?

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.

If my boat is out of the water for a period of time, will PropOne lose its performance? Does it need maintenance?

PropOne does not need maintenance (as it is self-cleaning once the boat gets moving on the water) and will remain intact even if the boat is left out of the water for extended periods of time and hauled out/launched repeatedly.

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.

How long does it take to apply? When can I have my boat back in the water after application?

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.

Is PropOne suitable and recommended for sterndrives and IPS drives?

PropOne is indeed suitable and recommended for sterndrives and IPS drives, it works well for this application.

See our testimonials for images of PropOne applied to IPS and sterndrives!

Can PropOne protect against freshwater growth?

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!

Do I have to remove my existing PropOne coating entirely to re-new? Or can I just top up with a clear coat?

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.

How should new propeller metal be prepared for PropOne application? And how do you know when a surface is ready for application?

See our New metal PropOne application PDF

See technical data sheet and brief application guide for more information

Is Prop Wash mandatory for application?

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 helping to dry the metal can often leave contaminants inside the porous metal. That could affect adhesion.

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

How do you know the PropOne primer coat is ready for clear coat application i.e. Touch dry? And how many coats of Primer/Clear Coat are needed?

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 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.

For more information, please refer to the brief application guide and technical data sheet.

Can you partly use PropOne primer and save the rest for later? If so, how do I split it?
