And, its superb coating is definitely dependable in impeding early deterioration yet it executes gradual polishing action that is good at reducing needless paint buildup. a 1” putty knife for cleaning the prop and shaft as well as tighter areas– a plastic putty knife is less likely to scrape the bronze propeller, but will wear away with use. We have to replace it every 3 or 4 cleanings.

Non marine-grade products: Non marine-grade products should be avoided when cleaning a boat hull as they can pollute the sea water or get damaged easily due to the corrosive seawater Ablative Bottom Paint. This is softer and enables the coating to subside at a regulated rate. This is the reason why it is was called self-polishing bottom paint. The disappearance of paint enables for new, un-oxidized paint to be uncovered.Furthermore, what makes this product good value for the money is its unrivaled multi-season protection. This implies that it can offer the best possible shield for your boat. Its size (per gallon) can already cover an area that is as big as 430 square feet.

However, this timeframe will vary based on the condition and the size of the vessel with larger 50ft+ hull lengths taking over 1 hour to clean. Regardless of the type of paint, if you start near the waterline and work down, you’ll be less likely to scrape your head or shoulders on barnacles as you ascend.If you’ve gone to the trouble to carefully prepare your hull, you’ll want to use at least a medium hard paint to get a final surface as good as the subsurface you’ve created.

Overall, it’s a solid multi-purpose and multi season paint that you can apply on just about anything made of metal, as you know, it will be a rust or corrosion problem over time.

I prefer to use bottom paints like this on my Jeanneau cabin cruiser, which I like to take for my longest cruises. Mostly, it’s because of the sheer longevity of this paint. The longest I’ve made it with a single hard coating is two and a half years on solely freshwater with a combination of dry and wet storage. This is one of the few antifouling paints I’ve been using for a long time now.

I used two thin film coats as per recommendations, and the boat had minimal to zero build ups for that entire time, thanks to the biocide and the way sheds taking most of the gunk with it. As much as possible, I choose this over anything else, assuming it’s available. It’s far cheaper than a lot of reliable bottom-side boat paint products out there. And it’s mostly because I get the most value for money out of it. For some reason, barnacles seem to really like to grow up inside thru-hulls, and have to be scraped out with a screwdriver. This has to be done carefully so that you don’t chip your bottom paint off the thru-hull.

After cleaning the bottom twice with just snorkel gear, we bought a hookah and have never regretted it. You definitely need at least a mask so you can see what you are doing and fins sure help – particularly if you’re free diving. Thoroughly pressure-wash your boat on a regular basis to remove salt debris or other sorts of marine growth and filth that could accumulate. Use cleaning agents that are especially formulated to shield your vessel’s finish. Wearing an old wetsuit when you clean the bottom of your boat can protect your skin from cuts and scrapes.
