Antifouling coating to protect your ship

Antifouling coating is a coating that inhibits the growth of organisms that mostly attach themselves on ship hulls. It is very common in Hong Kong. Since the country is located next to a sea, a lot of the local marine boats encounter fouling. The performance of the boat and the durability will decrease over time if nothing is done about this fouling growth. Thus, an Anti fouling coating is the perfect solution. The gouvernement agrees, introducing, since november 2016, a new regulation where anti fouling systems are the new standard to apply on boats.

From the slightest sign of fouling to full growth, all visible fouling will affect your boat. It will slow down your boat’s speed quickly and the hull will be more prone to detoriation.

The top four reasons to say yes to Anti Fouling

  1. Prevent damage by aquatic organisms
  2. enhance the durability
  3. increase speed
  4. cut down the costs.

The right type of anti fouling coating for your boat

There a few different types of anti fouling coatings. Available in many sizes and forms. But you should keep in mind that just going for the coat that suits your boat type is not always the best solution. Nowadays, forgetting about the type of water it is in and the usage purposes is not aAnti fouling coating-on-ship-in-watern option. So to make it easier for you, here are the two basic types of anti fouling paints in which you can categorize the boat in. To make it easier, here are the types. characteristics are named, so that every boat owner can find the most suitable coating for his boat.

  • Hard anti fouling: This coating is strong enough to withstand cleaning with a cloth without the coating coming off. It also has a long durability. But as all coatings, they will not last a life time. The present biocides will slowly dissolve in the water. Eventually, often during seasons when the boat is not cleaned properly, the fouling will build off and coating will damage. This type of coating is very popular for race yachts and power boats.
  • Eroding coatings: Like the name already gives away, will eventually wear away. This also means that the anti fouling rips off, and has to be reapplied more often. The biocides of the paint will be washed out so there will be still paint on the hull of your boat, but that does not mean that the protective coating is still there as well. It’s suitable for cruising yachts and motor boats. Eroding coatings are cheaper than hard antifouling coating.
  • Copper based: This type of coating is formed of epoxy resins which are mixed with copper  powder or copper nickel alloy. This is an expensive alternative, but it does provide long term protection.

Only anti fouling paints that are registered pesticides can be used in Hong Kong

Innovative antifouling developments in Hong Kong

This antifouling paint prevents the organisms in the water to attach themselves to the hull of the ship. Because the coating is hydrophobic, a layer of water forms on the surface of the hull. This misguides the organisms into thinking that the hull of the ship is liquid, not solid. Resulting in less organisms growing on ships.

Enzyme based antifouling coating

The most common anti fouling coatings are metal basis. Since these biocides and metals aren’t that good for the environment, people created enzyme based antifouling coatings. This type of coating is environmentally friendly.

Nano anti fouling paint

Nano coatings are used for more and more objects every day, and now there’s already a Nano antifouling paint for ships. This Nano coating manages to make the surface of the hull so slippery, that no organisms and bacteria can attach themselves to the ship at all. This is because the coating is able to completely absorb into the surface of the object. At the moment, only motor boats use these coatings. But this coating is going to be used more in the future for more type of boats. Research has already shown that the coating indeed works and fights off every organism.

Additional information when applying Antifouling coating

Here are tips which make the result even better! Antifouling-coating-on-boat

  1. Choosing to apply the coating with a brush or roller gives accurate results but takes long to finish.
  2. If you want to cover a big area at once, a larger width brush is perfect to apply it with.
  3. Prepare the boat. Look if there is still some paint left on the boat or wear and tear. Once you’ve removed that, you’re ready to start.
  4. Apply extra layers of paint to parts that have to endure a lot. Such as the hull, outdrives, rudders, waterlines and other trailing edges.
  5. And always follow the guidebook to prevent peeling, cracking and blistering during or after the applicatio
