Propspeed®

How to Apply

In the Kit:

Propspeed Propclean Wipes

1 Propclean

The denatured alcohol in Propclean ensures that the metal surface is now completely free of contaminants and ready for Propprep. 
Propspeed Propprep Wipes

2 Propprep

Propprep is critical in the chemical preparation of the metal surface to be coated. The low percentage of phosphoric acid treats the metal in preparation for the Propspeed Etching Primer.

 

Propspeed Etching Primer Base and Hardener

3a&b Etching Primer Base & Hardener

Propspeed Etching Primer Base & Hardener combined are one of the best underwater Etching  Primers on the market. Known best for its tenacious adhesion and corrosion resistance.

 

4 Clear Coat

The non-toxic, slick top coat that repels marine growth and contributes to lowering boat owners’ running costs. More speed, less fuel.

 

* Propstrip

Propstrip

Simple way to pull labour costs out of your re-application process. Let Propstrip do the hard work for you.

Application Tip

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.

Ambient temperature has an effect on the application of Propspeed and the drying times of the Etching Primer and the Clear Coat. We recommend a minimum temperature of 10°C, 50°F. It is also recommended to avoid applying the product in direct sunlight or humidity above 85%.

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.

Preparation

* Metal Preparation

For first time Propspeed applications, the metal surface must be abraded to an 80 grit profile to form a mechanical bond. This can be done using a dual-action sander, or by hand using wet and dry 80 grit sandpaper. 

Any remaining old Propspeed coating needs to be removed completely before a fresh Propspeed coating can be applied. Pressure wash the existing coating to remove marine foul from the surface, then allow sufficient time to dry. Propspeed can be removed by sanding using 80-grit sandpaper. A dual action or air driven sander can be used and difficult areas wet sanded by hand.

Alternatively, for quick and easy removal, use Propstrip. You can read in detail about how to remove Propspeed with Propstrip here. 

You must wear a dust sanding mask when removing old Propspeed - inhaling any residue could be harmful.

With any surface coating, proper surface preparation is essential.


Application Tip

  • High pressure clean previously applied Propspeed
  • Ensure surface is thoroughly dry before sanding
  • Wet sand difficult areas

1 Initial Clean

Once the surface has been sanded and/or had the old Propspeed chemically or mechanically removed it’s time to clean the surface with the Propclean wipe provided.

 

Application Tip

  • All surfaces must be wiped down with Propclean
  • 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

Critical Information

Be prepared! Once you start this stage of the application process you need to finish it without breaks. Ensure all product is mixed and ready to go, and all the tools you’ll need are easy to access. You may need to work in sections, applying both Primer Coats and the Clear Coat to one area before moving on to the next.

3a&b Etching Primer

Ambient temperatures influence the application of Propspeed and the set times of the metal Etching Primer and Clear Coat. We recommend a minimum temperature of 8 degrees celcius. In hot conditions never apply the product in direct sunlight or in humidity above 85%.

The yellow pigment in the bottom of the Etching Primer Base can 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.

You can use foam rollers or brushes to apply the Etching Primer.

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

  • Ambient temperatures influence the application process
  • Check weather conditions beforehand
  • Consider using a thermometer for exact ambient temperatures

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 coats.

Ensure the Clear Coat is well mixed. Apply using a brush only (no foam rollers). Apply one coat only, much the same way you would the last coat of varnish.

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

Make sure the surface is completely coated with Clear Coat. Any missed areas will appear dull in luster. 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 in the Clear Coat.

Propspeed requires a minimum of 8 hours to dry before launching. In cold conditions, 5-13°C , 40-60°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, however it does need to be covered to protect against UV light.

During cleaning of 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
