PropOne Vs. PropGlide

It is widely accepted that a build up of marine life on the surface of a boat’s propeller and drive shaft negatively impacts engine efficiency and performance. Even if the prop has a thin layer of growth on it’s surface area, fuel efficiency is reduced by a significant amount. To counter this problem, engineers have turned to developing “super-slick” coatings. When the drive is engaged, and the prop begins to move, any organisms attempting to adhere to the prop simply slide right off! No chemicals are used to poison or kill the organisms in the environment.

How do PropOne* and PropGlide compare?

Which coating gives you the most bang for your buck?

PropGlide is much newer to the market than PropOne, but has been in development for over ten years. Being new to the slick coating market, PropGlide appears to be able to avoid slipping into the same ruts that their competitors have. The biggest obstacle for PropOne is the cost. Comparing the two products at price point, PropGlide is about 30% less expensive and offers 25% more product. That’s 2 strikes for PropOne right off the bat. PropOne is available in the following sizes: 1000mL, 500mL, and 250mL. On the other hand PropGlide offers a size larger than PropOne’s 1000mL and still manages a lower cost. Also PropGlide offers a size smaller than PropOne’s 250mL for sailboat owners who don’t need the larger quantities of product. (For more information on choosing the right size of PropGlide, see this Coverage Chart.)

In terms of performance, both slick coatings are equally good. They do the job and do it well. It is too early to say which product will outlast the other in the minds of consumers. But for right now, we recommend PropGlide as opposed to PropOne. The savings alone makes PropGlide worth every penny.

 

 

 

 

*PropOne was formerly known as PropGold. It is essentially the same product, just a different brand name.

This PropGlide Technical Data & Application Guide will detail how to apply any size kit of PropGlide by detailing the best preparation of the surface and application of the etching primer, and the final application of the Clear Topcoat.

Preparation of the Surface

The preparation of the surfaces to be coated with PropGlide is the key for the product to work effectively.

1. Remove previous coatings, fouling organisms/marine growth from metal surfaces. All substrates that are to be coated with PropGlide must be bare metal. These areas should be machine sanded with a Dual Action sander fitted with a soft pad and 60-80 grit abrasive discs sandpaper. Sanding the surface by hand is recommended at hard-to-reach areas where the dual action sander cannot reach. Use 60 – 80 grit wet/dry sandpaper, with water as a lubricant. Make sure the sand paper is changed frequently to ensure the necessary profile is achieved. Hand sanding these hard-to-reach areas is required to ensure the surface is properly abraded. The shaft should be done with hand sanding rather than using a machine. From this point forward, there shouldn’t be any direct hand contact to areas which are to be coated with PropGlide. It is advisable to wear latex gloves as it will ensure the areas to be painted remain clean and sound.

2. Once the surface sanding process is completed, wash all the areas with clean fresh water and wipe with clean, lintfree cotton rags soaked in water to wipe off sanding residue. Continue doing this until the rags don’t show any sign of residue, contaminants or discoloration.

3. After cleansing with water is completed, use a rag soaked in acetone or denatured alcohol to remove water on the sanded surface.

Continue to use the rag until it becomes dry from evaporation of the acetone or denatured alcohol. Use one or more rags as required, until the rag looks white clean, as there will be no contaminants when the rag is white clean. Again, care should be taken not to touch cleaned surfaces with bare hands. This is because fingers and hands contain oils which can transfer to the cleaned surfaces and therefore would inhibit the adhesion of the coatings.

Apply the Etching Primer

There is a Primer Base (Part 1) and a Primer Hardener (Part 2) to activate the primer base. This two-component etching primer dries chemically by reaction of the mixed components and provides protection against corrosion and increases the adhesive property of the subsequent coats. It may be used as a pre-treatment primer on non-ferrous metals such as bronze and aluminum as well as zinc and galvanised iron. May also be used as pre-treatment primer on blast-cleaned steel plates.

Temperature Limitations: Primer and Topcoat should be brought to 70-80°F (21-27°C) temperature range prior to mixing and application. Apply in good weather conditions when air and surface temperatures are above 50°F (10°C). Surface temperature must be a least 50°F (10°C).

PropGlide Etching Primer Physical Properties

  • Mixing Ratio: Primer Base (Part 1) : Primer Hardener (Part 2) = 4 : 1 by volume
  • Colour: Primer Base (Part 1) : Yellow, Primer Hardener (Part 2) : Clear
  • Dry Film Thickness: 8 microns
  • Drying Time: 5-15 minutes touch dry (temperature dependent)- 1 hour hard dry @ 20°C/68°F

Painting Interval: Apply PropGlide Clear TopCoat when Etching Primer is just touch dry Pot Life: 8 hrs @ 20°C/68°F

1. Agitate the Primer Base (Part 1) contents by scraping the bottom and sides of the can, as there will be settling. Mix contents of primer until the settled parts are incorporated back into solution and uniformly blended. Do not strain material, even if particles are present.

2. Stir Primer Hardener (Part 2) then add entire contents to the Primer Base (Part 1) container. Mix primer base and hardener for 30 seconds and apply mixture to sanded surface immediately after mixing.

3. Application of the Primer Base/Hardener mixture should be thin. The film should be thin enough, so that it is barely coating the surface, yet it does not provide sections or lines on the sanded surface that are not coated. Do not touch the primer mixture as it dries. The method of application of the primer may be done by using either a natural bristle brush or foam roller. 4. Apply a second coat of Primer Base/Hardener mixture after the first coat dries.

Apply the Clear Top Coat

The Clear Top Coat that should be applied to the last coat of Etching Primer within 5-15 minutes. The Clear Top Coat serves as a slick finish that will inhibit marine growth from attaching to the surface.

PropGlide Clear Top Coat Physical Properties:

  • Binder type: Silicone Polymer
  • Solvent: Xylene
  • Colour: Clear coating
  • Finish: Glossy
  • Dry time: 45 minutes touch dry ; 8 hours hard dry @ 20°C
  • Recommended film build: 75 microns per coat
  • Thinning: N/A
  • Clean up: Acetone
  • Shelf life: 12 months

1. After 5 to 15 minutes (depending on temperature) of applying the 2nd coat of Primer/Hardener mixture promptly apply the Top Coat. Application of Top Coat should be thicker than Primer/Hardener mixture, yet not thick enough so that the Top Coat produces runs. The Top Coat is to be applied with brush only, NO foam applicators are to be used.

2. Let the Top Coat dry overnight before launching.

Propspeed Vs. PropGlide

Propspeed ReviewFoul Release Systems Like Propspeed and PropGlide provide the best solution to keeping growth of your props and running gear. While these are not antifouling prop paints, they do keep the growth off buy creating a super slippery surface that the marine growth cannot stick to. Propspeed recommends that their kits by applied by a professional Propspeed applicator. On the other hand, PropGlide is available for any DIY applicator and is 30%+ less and more product for the money. If you want to apply this yourself, be sure to follow the details in the respective application manuals.   You can find these on any of the Propeller Foul Release Kit listed on our website.
PropGlide is newer to the market, but been in development for over ten years, while Propspeed  has been available for many years and is the leading brand name in the market place. The biggest issue with Propspeed is the cost. Very expensive!  PropGlide is also expensive but 30% less than Propspeed. In addition, you get 25% more product with PropGlide , so be sure to get the right size. You might be able to use a smaller size kit with PropGlide  which could then save you over 50%! You can find the comparison on PropGlide’s web site: Propspeed Compared

Performance of both coatings has been comparable, with much fewer complaints about PropGlide   Either they are just newer in the market with less complaints, or they truly have improved performance. Time will tell. At this point we recommend trying PropGlide  as a Propspeed alternative – since there is comparable performance with Propspeed, the cost savings alone is worth it! And PropGlide offers a sailboat size kit making it affordable now for sailboat owners.

PropGlide Frequently Asked Questions

logo-200x43 How does PropGlide work? PropGlide is a coating system that is applied to the props and underwater running gear of any vessel. Once applied, the PropGlide system reduces friction to the metal surface which greatly improves efficiency by not allowing growth to stick to the underwater metals. The result is an improvement in prop speed and fuel efficiency.

Is PropGlide toxic? Not at all. PropGlide contains no toxic biocides. It works be creating a super slippery surface not allowing growth to attach to the props and underwater metal.

Does PropGlide prevent barnacles and zebra mussels? No. It does not prevent from occurring. Barnacles and Zebra mussels will still grow. However, they will NOT attach. As soon as the vessel starts moving, the growth slides off with ease!

What can I expect after applying PropGlide to my props and running gear? You should expect growth not to stick to the properly prepared and kept surface while experiencing greater fuel efficiency and speed.

Can PropGlide be used in salt water and fresh water? Yes, PropGlide may be used in any type of water, including fresh water, salt water and brackish water conditions.

propglide foul release coatingHow long does it take to apply Propglide? The application time varies by the size of the prop(s) and running gear that you are covering, but typical application can be done in a few hours. Please see our application guidelines for detailed information. Note: Remember to wait overnight before launching your vessel!

Who can apply PropGlide? Unlike many other foul release coatings, you may apply PropGlide yourself by following the application guide, or you can contact a local boatyard or dealer in your area to apply it for you.

If I haul me boat after I have applied Propglide, will it still work after leaving the boat of the water? Yes, PropGlide can be left out of the water without affecting any performance of the system.

How long will PropGlide last? There are many factors that can affect the longevity of PropGlide including number of hours and kilometers traveled, various environmental factors including water temperature and purity. PropGlide will last 1-2 years depending on the above factors.

Can I recoat PropGlide for my next haul out? You must remove all of the old PropGlide by sandblasting, sanding, scraping, wire wheel or grinder. After all old PropGlide is removed down to the metal surface, clean the area to be primed with Xylol or Acetone. Recoat PropGlide using the application guidelines.
