Lead Keel


Anyone ever blast a lead keel on a boat before? Wondering if it's a safe thing for me to do? Any input would be greatly appreciated!

Re: Lead Keel


Thanks!! That's the part I was kind of afraid of. Other then masking off the area with plastic what other options are there or is that even enough? I guess a dumb question is why would they use that material on a boat anyway?

Re: Lead Keel


Not sure, I'd look at chemical stripping instead. If you remove any lead by blasting and your waste will all be haz mat.

Re: Lead Keel


Lead has been used for sailboat keels for centuries. As a solid mass of material it is basically inert causing no harm to anyone or any creature. I blast them wet onto a tarp, some guys scrape them down, others sand them with discs (the stupid ones). Everything just gets tossed into the boatyard dumpster where all the other nasty stuff goes. Boatyards are the final wild frontier when it comes to environmental regs and controls

Re: Lead Keel


That was my original plan doing it wet with some plastic barriers. I just don't to get myself into some EPA issues.

Re: Lead Keel


BTW, lead keels are actually an alloy with antimony (as I recall) which makes them quite hard. Blasting them is more like blasting cast iron, the lead doesn't give itself up very easily, paint and growth comes of readily and you end up with very little metal on the ground.

Re: Lead Keel


The EPA has a short guide on how to comply with the rega in a marina. Google will find it.

M&R
Your in Maine. You need to read the marina rules and regs on blasting in
The boat yards. All boats must be tented and bottom paint treated as hazmat materials.
Old copper paint on alot of boats.
Now with that being said, you can blast the lead keel as its in a sealed tent under the boat.
All paint must be cleaned up in sealed bags and disposed of proporly.
Wear your ppe

This is way we don't. Wet blast boats ...

Re: Lead Keel


One other note, lead tends to oxidize rather quickly. You have to get a barrier coat on to it the same day of you're just wasting the customers money. Lead oxidation won't allow the paint to stick and the paint will just peel off once in water leaving one pissed off customer.

Re: Lead Keel


Needs to be treated as a lead job as does the bottom paint.
Your getting reimbursed for Services, makes it a hazmat job.
If the owner does it him self he can do it any way he wants to.
(take the lead class that Maine offers)

Boats need a complete tent under and around the boat. (encapsulate) to keep any media from getting out. (DEP and EPA rules)


I have tried many ways over the years, and boats are costly no mater how you do them. (yes wet, dry and hand prep...)
Dry is best, clean up wet sucks!


every state has about the same regs on boats, but they do change some.

Not really. You just don't have to worry about contaminating the ocean.

You really really should understand compliance before doing this.

I've been blasting boats for over 18 years and every boat yard does not want you to let materials
hit the ground. Most will not let you through the waste in their dumpsters.
the reg states that it must go to a clean landfill, which means it can go into a reg dumster. But not the boat yards.
doing it at someone's house, well if the neighbors call DEP, and there's a stream or wetlands near by, well get your check book out....
just saying.
all boat yards are only aloud to wash boats if they have a catch basin that will filter out waste.
Maine states that all boat paint should be handled as if it is hazardous material till disposed of properly

Yup, and if you powerwash, all the water gets collected before hitting the ground and filtered before the solids are disposed of and the water is disposed of. That's why I keep saying he needs to understand what he needs to do for compliance. As long as we're talking about Maine, our RRP laws are slightly different from Federal regs - more strict. The Federal guide says check with your state for disposal...

Re: Lead Keel


I definitely will be doing some reading on these guide lines before touching anything. They hold higher regulations for paint removal on marine over automotive typically? I'm guessing because different types of paint used? I'm still learning as I go with things here sorry guys. I'm looking to do things right and by the book that's for sure. Thanks for all your input.
