(0 customer reviews)

From 78.18 

Self-cleaning antifouling coating.

  • Biocide free
  • Long Lasting
  • Easy to apply
  • Insulates against galvanic current.

Crystal Prop coating is ideal for propellers, shafts, struts, flaps and engine cranks (according to tests: it resists more than 6000 hours to salt and acid with eletricity)
When applied, it creates a durable hard, slick surface that marine growth does not adhere to. Crystal Prop does not need a primer, thanks to its superior adhesion to metal. This makes it extremely durable and will hold up to propeller cavitation. The Crystal Prop kit consists of two bottles containing paint and hardener, which are mixed with a 1:1 ratio. This is a single-coat application that can be applied by brush or spray.

Each Kit Includes :

  • Paint
  • Hardener
  • Mixing container

propellers with crystal-prop
Crystal Prop creates an extremely smooth propeller surface resulting in decreased water resistance. This improves the overall performance of the vessel, resulting in higher hull speed, lower fuel consumption and resistance to the onset of cavitation. Marine growth will not attach to the paint. A treated propeller cleans itself as soon as it starts rotating, unlike traditional antifouling paints Crystal Prop will not lose its effectiveness with more use.


It creates an excellent barrier against corrosion, by forming a strong protective film over the metal blocking it against galvanic currents. This will extend the life of sacrificial anodes. Crystal Prop is an ecologically friendly product; free of harmful toxins, biocides and metals.


Looking for a hassle-free solution to protect your boat from fouling? Look no further than Crystal Prop. Unlike other antifouling coatings, Crystal Prop is incredibly easy to apply. You can use a brush or spray gun to apply a single layer, and that’s it! The result is a durable protective coating that keeps your boat looking and performing its best. Plus, with a dry-to-the-touch time of just 2 hours and a launch-ready time of 48 hours, you’ll be back on the water in no time.


  1. Clean The Surface
    Clean propellers and underwater gear well. Remove all traces of marine growth, contaminants, old antifouling and grease.
  2. Prep The Surface
    Sand metallic surfaces with 80 grit sandpaper. For sterndrives and saildrive legs with original metallic coating; use 120 grit.
  3. Clean Surface
    Wipe down the metallic surfaces with acetone to remove any signs of dust, oil and grease.
  4. Mix Crystal Prop
    Mix Crystal Part A and Hardener Part B in a 1:1 ratio. Be sure to mix thoroughly and gently so as not to create bubbles.
  5. Apply Crystal Prop
    Apply Crystal Prop using a brush or spray gun (1.2mm nozzle and filters up to 190 micron). Apply only one coat in a thin, smooth layer (approx. 60 micron).
  6. Let Dry
    Crystal Prop will be touch dry in 2 hours, fully dry in 12 hours and the boat will be ready to launch in the water in 48 hours.


Q: How long does Crystal Prop take to dry?
A: Crystal Prop is dry-to-the-touch in just 2 hours and launch-ready time of 48 hours.

Q: Do I need to apply primer before Crystal Prop?
A: No primer is needed.

Q: What colors are available?
A: Only Clear is available at this time.

Q: Is Crystal Prop toxic?
A: Crystal Prop is an ecologically friendly product; free of harmful toxins, biocides and metals.

Q: How does Crystal Prop work?
A: It dries to a hard and slippery surface that allows it to function like an antifouling paint. Marine growth can not adhere to the surface, once water flows over the surface any growth will slip off.

Q: What is the shelf life of Crystal Prop?
A: Crystal Prop has a shelf life of 2 years if unopened and stored in a cool, dry place. However, once opened, it can only last up to 6 months if resealed correctly. To ensure that the product stays fresh, it is important to seal the bottle securely and store it upside down after opening.

Q: Is Crystal Prop repairable?
A: Yes, for re-application it is sufficient to sand the surfaces with 240 grit sandpaper and apply again.


A 100ml kit of Crystal Prop will cover approximately 1.5 square meters or 2,325 square inches of metal.
