New Application Technique

Simplified application process, flawless finish, applied like a pro



Experience a faster and easier application process with the new, All-In-One Propspeed Application Kit! The kit also introduces a new application technique launched as a part of our Like A Pro approach. The new application technique using the 4" Propspeed Rollers introduces a more efficient technique compared to traditional brushing methods, achieving a more consistent finish.

For instance, when applied to a 33-inch, 5-bladed propeller, this technique reduces the application time by 35%.

For large commercial propellers, the time savings are significantly larger due to the increased surface area covered. This not only enhances efficiency but also reduces labor costs.


Dans le kit:

2 Propprep

Propprep est essentiel pour la préparation chimique de la surface métallique à revêtir. Le faible pourcentage d'acide phosphorique traite le métal en préparation de la couche d'Etching Primer Propspeed, le primaire d'accrochage.


3a&b Etching Primer Base & Hardener

La combinaison de Propspeed Etching Primer Base, le primaire d'accrochage, et du durcisseur, donne l'un des meilleurs primaires d'accrochage sous-marins du marché. Réputé pour son adhérence constante et sa résistance à la corrosion.


4 Clear Coat

C’est la couche de finition non toxique pour les surfaces lisses qui empêche l'adhérence des organismes marins et contribue à réduire les coûts d'exploitation des propriétaires de bateaux. More speed, less fuel.



The process to apply Propspeed to your running gear isn’t difficult, but the process must be strictly adhered to in order to get a superior result. Failure to follow the instructions precisely will likely result in premature failure of the coating.

The application of Propspeed requires planning. Make sure you have installed and taped over all zincs, all application gear is on hand, and you thoroughly understand the process – then you’re ready to get started.


Find Out How Much Propspeed You Need:

If your commercial vessel is under 100ft you can use the Propspeed Coverage Calculator™ app to estimate how much product you need to coat your underwater assets.

For larger jobs, we have a technically skilled and knowledgeable team ready to train, supervise, and support the integration and application of the Propspeed foul-release coating system. Please send an email to Clint Jones or get in touch with us using the button below.

    You can’t control the weather, (if we could it would always be boating weather right?), but you can choose conditions that will ensure the best application outcome. Propspeed is best applied when temperatures are in the 16°C / 60°F – 32°C / 90°F range, humidity is below 85% and all application surfaces can remain dry for the duration of the application and curing process. Plan to do the application when conditions in your area are closest to these parameters.

    Ambient temperatures influence the application of Propspeed and the set times of the metal Etching Primer and Clear Coat. We all know that there is a big difference between 60°–90°F, while it is not complicated, it is important to follow the correct re-coat window and drying time based on the environmental conditions you are operating in. Use the chart below to understand how environmental conditions influence the re-coat window and time your re-coats accordingly.

    You shouldn’t rush a Propspeed job, especially when you are working in open air. If the weather does not cooperate, or if it is too cold, too hot, too humid or too windy to start a job, we recommend you wait until conditions improve. The results will be worth the wait.



    Propspeed Application Technique


    * Metal Preparation - Reapplication

    If underwater metals are already coated with Propspeed, or if other coatings are applied, you will need to remove all other coatings before starting the new application. The easiest, fastest and recommended way to do this is with Stripspeed, a solvent-based paint stripper that has been specifically developed to remove foul-release coatings in less than 30 minutes. The thick consistency hangs on vertical and overhead surfaces and is easy to use. Just crack the bottle open to let some air in, shake well for 90 seconds until the consistency is thick and start using. Read the detailed application instructions on how to use Stripspeed here.

    Application Tip

    • As the last resort, old coatings can be removed using a dual-action or air-driven sander
    • You must wear a dust sanding mask when removing old Propspeed - inhaling any residue could be harmful

    * Metal Preparation - 80-grit Profile

    Once you have successfully removed the previous coating, sand the metal to achieve an 80-grit profile to prepare the surface for a mechanical bond with the first coat of Etching Primer. This applies to all  first-time Propspeed applications as well and can be done using a dual-action sander, or by hand using wet and dry 80-grit sandpaper. 

    With any surface coating, proper surface preparation is essential.


    Application Tip

    • High-pressure clean to remove marine foul from the surface, then allow sufficient time to dry
    • Old coatings need to be removed completely before a fresh Propspeed coating can be applied
    • Ensure the surface is thoroughly dry before sanding, and you can wet sand difficult areas
    • Plan ahead and mix any settled solids at the bottom of the Etching Primer Base can. This usually takes no more than 2 or 3 minutes.

    1 Initial Clean

    Once the surface has been sanded and had the old Propspeed mechanically removed it’s time to clean the surface with denatured alcohol.


    Application Tip

    • All surfaces must be wiped down with denatured alcohol
    • Ensure there is no residue remaining

    2 Metal Conditioning

    Apply Propprep solution liberally using the red Propprep wipe or solution. Immediately wipe the surface with a clean white cotton dry rag to ensure no residue is left.

    Propprep is acidic. Extra care should be taken when wiping the surface. The Propprep solution does not contain corrosive inhibitors, so the treated surface should be coated and primed with Propspeed as soon as possible.

    You are now ready to start painting.

    Application Tip

    • Use Propprep liberally
    • All surfaces must be wiped down

    Information essentielle

    Soyez prêt ! Dès lors que vous commencez cette étape du processus d'application, vous devez la terminer sans pause. Assurez-vous que tout le produit est mélangé et prêt à l'emploi, et que tous les outils dont vous avez besoin sont à portée de main. Il peut s'avérer nécessaire de travailler par sections, en appliquant les deux couches de primaire et la couche de Clear Coat sur une zone avant de passer à la suivante.

    3a&b Etching Primer

    The yellow pigment in the bottom of the Etching Primer Base must be thoroughly mixed before adding the Etching Primer Hardener. This usually takes no more than 2 or 3 minutes.

    Note: Failure to thoroughly mix the Etching Primer Base, as described above, may lead to premature hardening, inconsistencies and short life expectancy of the final coating system.

    Once there are no solids left in the can, add the Etching Primer Hardener to the can and mix again. Any product not being used immediately can be re-sealed in the can and left in the shade for up to 6 hours.

    Note: The cans are “short filled”, and the ratio is exact in the kit. It is best to mix within the can itself as you will pour only a portion of the product into the tray as needed, ensuring to close the lid when the can is not in use as solvents flash quickly.

    For best results and to achieve the time constraints, use one of the 4" Propspeed Rollers from the Propspeed Application Kit to apply the Etching Primer. A foam roller or brush can be used as a secondary option.

    The Propspeed system requires 2 generous coats of Etching Primer. To access all parts of the propeller and shaft we recommend turning the prop using a brush, wooden stick, or gloved hands. Once you have applied the first coat of Etching Primer wait approximately 3 to 5 minutes before applying the next coat. The timing of each coat is essential to enable the required chemical bond between coats.

    To test if it is ready use the dry-to-touch test method: touch the wet Etching Primer with your gloved finger – if it leaves a small print on the primed surface but no Etching Primer transfers to your fingertip, then you can begin applying the next coat. The wait between coats of Etching Primer is very important and must be adhered to.

    The 3-5 minute recoat timing is based on 27°C, 80°F temperatures, cooler temperatures will slow down the recoat time between the two coats of primer, as will warmer temperatures and windy conditions speed up the recoat time between the 2.


    Application Tip

    • Use the Propspeed Application kit to save time and achieve a consistent finish
    • Check weather conditions beforehand, ambient temperatures influence the application process
    • Metals retain the temperature from the night before so consider surface temperature before applying
    • Consider using a thermometer and surface laser temperature reader to make sure conditions are ideal

    4 Clear Coat

    You need to proceed with the Clear Coat as soon as the last coat of Etching Primer is dry to touch. Allowing the Etching Primer to dry completely may result in a failure in adhesion between the Etching Primer coat and the Clear Coat.

    Ensure the Clear Coat is well mixed and apply using the second Propspeed roller from the Propspeed Application kit (no foam rollers) or a brush as a secondary option. Apply a liberal coat to where it will not drip or “hang”. You have roughly 10 minutes to work with the Clear Coat before it starts to set on the surface you have applied to. If you feel you need to add more Clear Coat or spread areas out, do so within the fluid time of the coating before it skins over to dry. Once dry, do not add any more Clear Coat as it will not stick to itself.  

    Make sure there are no heavy runs or sags in the Clear Coat. You’ll have anywhere from 5 to 10 minutes to touch these up. 

    Make sure the surface is completely coated with Clear Coat. Any missed areas will appear dull in lustre. When you have finished coating the entire propeller with Clear Coat, give the propeller one more visual inspection just to make sure there are no areas that you might have missed and to check again that there are no runs or sags in the Clear Coat.

    Any drips that harden on the edges of the propeller blades can be carefully cut off the following day with a razor blade.

    Areas missing the clear coat will appear dull in lustre
    Propspeed requires a minimum of 8 hours to dry before launching. In cold conditions, 10-16°C , 50-60°F, we recommend at least 24 hours drying before launching. Unlike traditional bottom paints, Propspeed’s effectiveness is not adversely affected by sitting out of the water for extended periods of time in warm or cold climates.

    When cleaning your hull, only use a soft cloth on the Propspeed. If the wiping cloth collects shells remove them before proceeding with the wipe  down so as not to damage the Propspeed. Avoid any abrasive cleaning materials or direct high-pressure water.


    Application Tip

    • Do not use a foam roller
    • Apply much like conventional varnish
    • Touch-up runs or sags within 5 to 10 minutes
    • Use the 4" Propspeed Application kit for best results
