Thread starter trebor Start date Aug 22, Joined Oct 19, Messages My Uncle runs a certified Dupont bodyshop mostly for semi-trucks. He is very keen on Imron, but is not very familliar with boat bottom paints.
Would it be necessary to remove the bottom paint, or sand it smooth, seal it and paint it? Thanks, Treb Joined Jun 8, Messages 5, Re: Dupont Imron over bottom paint? My uncle seems to think that the imron sealer would bond very well to the bottom paint because he was involved when I done the prep before I applied it.
My only concern is that the bottom paint, having copper and those other chemicals might somehow keep the new paint from bonding well. Ralph Captain. Joined Jun 24, Messages 3, This should help - long and short is some are made to come off so I doubt you could paint over it with good results. Most contain copper compounds combined with other substances for particular characteristics. Some antifouling paints maintain a level of biocide near the hull surface, which deters growth from adhering.
Some paints and coatings rely on their inherent "slickness" to prevent growth from sticking. The abrasion created by the hull moving through the water reduces the paint thickness, exposing fresh layers of biocide to the surface throughout the boating season. Although the wear happens in a controlled fashion, it will wear off faster in higher drag areas on the hull and appendages.
This paint works well in high-growth areas and continues to be effective after haul-out and re-launch. Because ablative paints expose new biocide until worn completely away, additional coats add to their longevity. We recommend the application of three coats. Ablative paints with anti-slime additives are best for heavy fouling areas.
A practical side of ablative anti-foulings is that they can be applied over most other types of antifouling paints. Not recommended when you want a super-smooth bottom finish and have a diver maintain it since scrubbing removes paint and reduces longevity. Ablative paint is not the best solution for boats that are hauled and re-launched without a new bottom job like trailer boats and boats that are stored seasonally. Also, this type of paint requires thicker coats, which means more weight and more money since you need more product.
As the season wears on the paint will become less and less effective, because it "runs out of ammunition," meaning the amount of biocide it releases will decrease. When all the biocide is Cheap Bass Boats For Sale In Oklahoma Data used up, the thickness of the remaining paint is still the same as it was at the day the boat was launched a difference to ablative paints. Some hard antifouling paints have Teflon added to reduce surface friction. These products resist scrubbing and abrasion, making them ideal for avid racers who have their boat's bottom regularly scrubbed.
They also can be wet sanded or burnished for super smooth surfaces that produce very little drag. On the down side, they are incompatible with most other finishes and lose effectiveness when the boat is stored out of water. Avoid when you don't want paint to build up from annual paint jobs.
Paint manufacturers have incorporated them into their products, expanding their usability and effectiveness. Oversimplified, it's sunblock for your boat's bottom. Most boosting biocides work by preventing photosynthesis in the slime and algae that attaches to the boat. If the slime and algae cannot change sunlight into food they die or more likely they move on to another place that is more to their liking. According to Ciba, Irgarol dissipates rapidly, breaks down in water and is fairly low in toxicity to fish, shellfish, mammals and other marine animals.
In addition to reducing algae slime, Irgarol allows the copper bottom paint to do a better job on other organisms. The algae layer can actually reduce the amount of copper present on the surface, thus allowing animals to attach.
By controlling the release rate of the main biocide most antifouling paints use cuprous oxide and the boosting biocide you get longer lasting and more effective antifouling protection. The company says that paints containing Biolux are up to times more effective against slime than products solely based on copper. The reason is pretty simple: removing slime growth is one of the reasons that boaters scrub their boat bottoms.
When antifouling paint is scrubbed, even with relatively gentle materials like burlap, it inevitably removes some active paint film, and thus reduces the effectiveness of the paint. Since Irgarol and Biolux paint formulations remain cleaner, less scrubbing is required. They offer a super slick Teflon PTFE finish to keep growth from attaching to the hull in addition to one or more biocides. West Marine carries a complete line of products for these applications.
TBT tributylin tin was very effective but the toxicant remained in the environment and affected non-targeted species. As a result of the ban, West Marine stopped selling tin-based paints and replaced them with products that are differently formulated to protect the bottom of your Dulux Paint For Boats 2020 boat or outdrive. Paint makers continue to research and develop more effective antifouling products that don't have a lasting negative effect on the marine ecosystem.

You can leave the epoxy primer you hopefully have under the anitfouling, it works fine with anything, as long as it is sanded a bit. Any antifouling left wil boil up. DJ Guest. The bottom paint has to come off. Imron, by nature is somewhat aggressive. Bottom paint, self ablative, are not.
LubeDude Admiral. Joined Oct 8, Messages 6, Aluminum Boats For Sale Alberta Yupoo Yep, you have recieved good advice, remove the bottom paint, and apply the Imrom after sanding with grit.
The reason for the coarse sanding is that you want all the adheasion you can get. You must log in or register to reply here.
