What is an ablative bottom paint?

Ablative Bottom Paint Ablative paint is designed to gradually wear away as water flows beneath the hull, either from use or from the movement of tides and currents. Fresh biocide is exposed as the paint layers wear away, preventing marine fouling organisms from attaching to the surface.

What is the difference between ablative and non ablative paint?

If you are trailering your boat, or keep it on a lift you should always use an ablative bottom paint. Ablative bottom paint, also known as self- polishing bottom paint, is softer and allows the coating to wear off at a controlled rate.

How long does ablative bottom paint last?

Boaters recognized early on it is important to keep the bottom of their craft free of barnacles due to loss of speed and performance. The key is knowing when to pull your boat out of the water for a new bottom paint application. Ablative paints are typically reapplied every 1–3 years.

How long does ablative bottom paint last out of water?

The wearing away of the self-polishing bottom paint allows for new, un-oxidized paint to be exposed. Therefore, if you are trailering your boat, or it comes in and out of the water for any reason, the paint will oxidize within 72 hours.

Can you put ablative paint over hard paint?

Ablative paint is “soft” antifouling paint. It gradually sloughs off releasing more antifouling as your boat moves through the water. Ablative paint is great for boats that are used more often. You cannot put hard paint over ablative paint because the ablative paint sloughs off and will take your hard paint with it.

How do you clean ablative bottom paint?

1. Don’t scrub ablative paint underwater. Modern bottom paints, either hard or ablative, already do a good job of keeping fouling away. Usually a fast run or a light sweep with a hand or soft sponge will help the paint shed any surface coating — but don’t wait too long between cleaning runs (see point No.

Can you put ablative paint over hard bottom paint?

The basic issue in switching from ablative to hard paint is that the ablative paint can still try to wear away under the hard paint and will take the hard layers with it. If there are years of ablative paint build up, the recommendation is to soda blast the hull back to gelcoat.

Can I paint over antifouling paint?

Most modern paints should be compatible with each other. If you’ve taken the existing antifouling back to the yacht’s gel coat or epoxy coating, it’s recommended that you paint the hull with primer to ensure good adhesion. If your existing paint is flaking, you need to prime any bare or flaky patches.

Can I paint over ablative paint?

Can I paint over old Antifoul?

How does ablative paint work?

“Sloughing bottom paints”, or “ablative” paints, are an older type of paint designed to create a hull coating which ablates (wears off) slowly, exposing a fresh layer of biocides. Scrubbing a hull with sloughing bottom paint while it is in the water releases its biocides into the environment.

What does antifouling paint mean?

Anti-fouling paint is a special coating that is applied to the hull and propellers of a marine craft. The coating is used to slow down the growth of marine organisms such as barnacles, slime, algae and mossy weed.

Do I need antifouling paint?

No you do Not need anti fouling paint for your described usage. For proper prep, sanding and cleaning with acetone should do the trick. I highly recommend Pettits undercoater primer and EasyPoxy topside paint. It is easy to apply with foam rollers and yields a high gloss quality result.

What is ablative bottom paint?

Ablative bottom paint is a newer technology then hard paint. It is the preferred bottom paint of most users since it typically lasts longer and continuously exposes a new active outer coating that protects against marine growth.
