POSEIDON EXTREME

Hull osmosis and hull fouling are two different problems that can affect the hull of a boat. Hull osmosis is caused by water penetrating the hull, while hull fouling is caused by organisms attaching themselves to the hull. Hull osmosis can be a more serious problem than hull fouling, as it can weaken the hull and make it more susceptible to further damage. Our Poseidon extreme package comes with a bottom coat that prevents against hull osmosis and a top coat that prevents against typical fouling.

No, you will need to apply more of the bottom coat primer than you will Hull Pro. To cover 20 linear feet of your vessel hull, you will need to apply 64oz of Poseidon Extreme Primer and 32oz Hull Pro topcoat. The package is sold in this ratio so it is important that you calculate the linear feet you require to coat your hull and purchase accordingly.

Everyone’s water type will differ. It’s important for you to check with your marina to understand growth rate and patterns for your water type. Hull Pro is a fouling-release formula, and will require regular maintenance. We recommend you check our POST-APPLICATION CARE GUIDE for our recommended tools and tips for keeping the combination of Poseidon Extreme and Hull Pro looking its best on your hull, and for keeping your vessel protected.

Poseidon Extreme is able to be applied directly over existing anti-fouling paint after sanding as much of it off as possible. This eliminates the need for costly sanding and repainting with gelcoat. By using Poseidon Extreme as a tiecoat, you can save money compared to the traditional and more expensive process of removing and replacing the anti-fouling paint and choose to transition to a more eco-friendly topcoat like Hull Pro.

Absolutely. A good power washing can help remove stubborn and hard growth. We recommend using a 2500-3500 PSI gas power washer.

Poseidon Extreme provides an extra layer of protection that prevents hull osmosis, which Hull Pro alone does not. Poseidon Extreme primer is a bottom coat that creates a water-tight barrier between your hull and the water, protecting against hull osmosis. This package pairs Poseidon Extremewith the top layer of Hull Pro which creates a fouling-release ultra-smooth protective barrier that decreases adhesion between marine organisms and your hull. Giving you further protection, extending the lifespan of your boat. This package is especially necessary in saltwater environments or if your having issues with hull osmosis.

Poseidon Extreme can last up to 5 years under normal conditions. However, the reapplication interval may vary depending on the specific conditions that the boat is exposed to. For example, boats that are used in saltwater or in areas with harsh weather conditions may need to be reapplied more often.

If you do see some scuffs or damage, you can touch up the top layer of Hull Pro by sanding around the area and applying another coat of Hull Pro. Remember, you’ll have to wait 24 hours for your touch-up to dry, and 48 hours for Hull Pro to be fully cured after application (72 hours total) before you relaunch your vessel.

If you need to fix the layer of Poseidon Extreme, you’ll have to sand past the original primer coating, and reapply both Poseidon Extreme and Hull Pro according to original application instructions.

You must allow Poseidon Extreme 24 hours to cure, before you begin to apply Hull Pro.
