Bottom paint removing......

[billnpat]

See a lot of ads with old bottom paint removing.....for faster and better everything according to there ad's

Anything to that??? my boat is 13 years young....lots of coats....:huh:

look into some one in your area that does the new dustless blasting. Look it up online Dustless blasting.

Thanks.....but what I'm trying to find out is whats the upside??

Unless you plan on keeping you boat on the lift, keep your bottom paint as bare is not really an option in salt water :grin:

I used beer, a dust mask and a sander.

Yes, it sucked.

You will be amazed at the weight of all those years of accumulated paint. I did the chemical stripper method on my last boat, (very messy) and removed the weight of a grown man from the bottom of my boat. Bottom paint is very heavy due to metal content of the paint. Putting a gallon on the boat every year for 10 years can add hundreds of pounds of weight, thus slowing the boat also. In addition to the weight, there is the drag caused by the rough texture of a bottom with years of chips and flaking covered by more paint. I use ablative paints on my current boat to avoid some of the buildup. Next year I think I'm going to have my bottom soda blasted, barrier coated and repainted. I will gladly pay someone to do that, bottom work is a real PIA!

I had my bottom soda blasted last year. It had about 13 seasons on it. Definitely helped a little with fuel usage, plus I was able to check for blistering and barrier coat it. Renewed confidence below the water line..

Not all bottom paints are compatible with one another. Removing many old layers of bottom paint allows you to start over with an entirely new system. Keep in mind over the past 13 years the technology has changed quite a bit. Also old paint if there has been flaking over the years will be rough and that has impact on how fast the boat can move through the water. While more speed may not be your thing, this also means better fuel consumption. After I did ours we reduced our gph burn rates by about 1 gph at planning speed rpms.

Because of the potential health and environmental impact the first step should be to talk to the yard where the boat is stored. They may have a list of approved vendors and a contractor not on that list might have a harder time getting access to your boat.

There was a guy on my canal that had it done to his mid 70's Silverton last year. I didn't see them do it, but I did see it after it was repainted before it went back in the water. That 40 year old hull looked fantastic. Never got the chance to ask him if it made a noticeable difference. I also can't remember what he said he paid, but I seem to remember that it was pricey.
How much are they quoting you to do it.

$1000

When we had the 280 done (4? years ago), it was $ 750 for soda blasting, so the $ 1000 for a 310 sounds reasonable. The guy who did ours brought everything to the boat yard and tented the entire bottom with plastic. When he was done they just rolled up the plastic and that was that. Other than the missing bottom paint there was no sign he had ever been there.

The soda blasting works but it is not as environmentally friendly as Dustless blasting. This system can be used with a boat setting right next to it. If you can find someone in your area to do it this is the way to go. Check out the marine video. http://dustlessblasting.com/

I beg to differ with you on that. Dustless blasting involves using water with the abrasive medium. The result is a slurry of water, spent media, and bottom paint particles. The bottom paint contains harmful chemicals and is hazardous waste. Unless the dustless blasting is being done over an EPA approved water runoff catch basin it will create a huge environmental problem for the property owner. However most boat yard containment systems are designed for fall bottom power washing where bottom paint is a minor part (a few ounces) of the water run off. A dustless blast run off would contain pounds of bottom paint residue and I am not sure the filtering is up to the task of separating that much hazardous material

Without question a dry media blast is messy and environmentally nasty, but only IF done in an open environment. The dry media blast also results in spent media and paint particles, but if it is contained in properly prepared plastic tenting (basically creating a large plastic bag under the hull where the work is done) the environmental impact is negligible.

What Henry says is exactly what my boat yard says.....they only do it over the winter when nearby boats are all under shrink wrap....

 

[DougLas]

Did you guys watch the marine Video?

 

[DougLas]

"Unless the dustless blasting is being done over an EPA approved water runoff catch basin it will create a huge environmental problem for the property owner?" Not sure where this theory has come from. In watching the video most of the water vaporizes into the air. Leaving very little clean up. Where did the water run off basin come from? I watched this blasting done on My Classic Car show and there was no need for special drainage there either.

 

[DougLas]

Another point to consider when soda blasting along with regular sanding. Wind in the wrong direction and boats down wind will end up with bottom paint dust on them. No matter how well the boat is covered it still happens. There have been reports of radars not working right with bottom paint dust on them.

Soda blast the hull....skip the rest. You will never regret it or look back.

$1000

Does that include doing a barrier coat after he blasts the bottom? If not, did you get any prices for that yet?
I may be interested in that price range. Pretty sure the number was higher than that for the guy on my canal.
