PropOne Testimonials

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 slick surface of PropOne reduces the adhesion of marine growth, such as barnacles, tubeworms, weed, slime will struggle to stick onto your running gear! With bonus benefits like:

PropOne will maintain its performance for at least 1 year in the water. Eventually it will start to lose its effectiveness, however it’s not uncommon for performance to be maintained for 2+ years!

Unlike conventional antifouling, PropOne does not wear away and dissolve with time and motion through the sea. When antifoul is applied to running gear it typically struggles to adhere and in service will polish away too quickly to give long term protection against fouling. Read more here!

Do not apply PropOne to anode surfaces. Best to either:

  • Mask over anodes with tape before applying PropOne.
  • Remove anodes and mask off the surface below the anode.

Once applied, there is no maximum time to launching! 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.

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

It’s hard to recommend and give 100% assurance and that’s why we usually recommend to remove the coating scheme and start again. However for small areas it doesn’t always make sense to do this!

To do the touch up we recommend abrading back the damaged area to bare metal, making sure to work to an area that is undamaged. Then wash down with fresh water.

Then washdown the area with Prop Wash, then freshwater again. Then dry the entire area with acetone or ethanol including the undamaged area.

Apply a tape line to protect the undamaged area. Follow with the normal instructions for application of PropOne Primer to the abraded area, then before applying the Clear Coat remove the tape and overlap the Clear Coat over the fresh primer and undamaged (older) 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.

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.

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

PropOne ULC is a highly transparent Foul Release Coating specifically designed for application to underwater light lenses without any loss of light.

Yes you can use our Underwater Light Coating (ULC) clear coat on transducers.

PropOne ULC is a transparent foul release coating. It’s silicone based and metal free so it won’t affect the transducers’ sound wave functionality.

With regular vessel usage, no in-water maintenance is required.

If your vessel is left for a long static period and some lingering marine growth develops, all that is needed is light underwater wiping with a non-abrasive cloth or sponge.

PropOne can be used in fresh or saltwater. The coating surface is not altered by variations in salinity. Freshwater fouling organisms will find it equally as difficult to stick to the surface of PropOne as their saltwater cousins!

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.

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