Bahamas - Bottom Painting

When I get to the Abacos next winter, I plan to 'bottom paint' the hull. I have 2 gallons of ablative bottom paint (non-tin based) on board which I plan to use, with the addition of 'Sea Hawk Tin Booster' tributyl tin additive. After reading the instructions of the 'Tin Booster' , it mentions that it may not be compatible with 'non-tin based' paints. Has anyone out there had any experience with 'Sea Hawk Tin Booster' (the clear stuff that comes in an 8 Oz. bottle) with non-tin based paint. Any gelling, or other problems????

Thanks,

tom

Re: Bahamas - Bottom Painting

I guess ya want to use a paint ya have! thats the only reason to use it when they have stuff down there ya can't get in the US!! I used to look forward to haveing the bottom done down there just for that reason !! but now Im in LA. and get good paint here ! Im sure that the bottom cleaning guy can tell ya if this stuff will work for ya ! or the paint maker could tell ya if it will work ! maybe an e-mail ?? Just a thought

What part of these instructions do you not understand?

"Mix desired amount of Tin Booster to your paint. Do not mix with non-tin based paints. It could cause the paint to gel."

Re: Bahamas - Bottom Painting

What if the desired amount is fifty gallons? Will I need a bigger can?

you could get a bunch of smaller cans and stack them up or get a bigger boat

Re: Bahamas - Bottom Painting

As a follow-up, I checked with Sea Hawk and they confirmed NOT to us Tin Booster in non-tin paints. I did a test with a very small sample of TB and an Ablative paint I have on board. TB makes the 'non-tin' paint sort of 'curdle' for want of a better description.
The Sea Hawk rep who I corresponded with via email suggested that I add their additive 'Bio Boost' which is zinc based to my non-tin paint. Has anyone out there used 'Bio Boost' and if so, was it effective in controlling marine growth? Barnacles in the Abacos seem to not be a problem on our 3 cruises there over the past 5 years, but 'grass' does form quite readily. Comments regarding Sea Hawk 'Bio Boost' welcome (not interested in sarcasm)!
Thanks,
TOMJ

half this forum is about sarcasm,,,,,,,,,, take it like it is meant,,, just fun,,,,I have not used that bottom paint. the water moves more in the bahamas, that is one of the reasons barnacles do not grow on the hulls, grass will be a problem, but after spending 6 months there i never did have to scrape the bottom, i used micron 66 and had good luck. It was a hard bottom paint. I used a soft paint once and left for 3 months. came back (boat in miami) and had every barnacle and ther cousin on my boat, that is when I went to micron 66

Micron 66 is not a hard paint. It is a "hybrid" ablative, meaning it shares attributes of both hard and ablative paints.

You didn't have barnacles because the paint you used was ablative, you had barnacles because the paint you used was ineffective against barnacles. The anti fouling properties of paint products are not determined by whether or not they are hard or ablative. What works and what doesn't is largely dependant on the fouling conditions where they are being used, not whether they are hard or soft.

Re: Bahamas - Bottom Painting

If your main problem is grass, stop at a feed store and buy the powdered form of tetracyclin . Take it with you and mix about a pound of it with five gallons of bottom paint, Grass wont grow on it.
All the best,
Clif

Or if it does, it'll, at least, be disease free*.

*Tetracycline is claimed to inhibit barnacle settlement by interfering with prior bacterial growth on the surface.

you can learn something everyday.

The original paint was a very soft bottom paint that was supposed to be put on a boat that moves. From what I had been told it was supposed to flake when something attached itself to the hull. when the boat was sitting it did not flake off and allowed the barnacles to adhere to the hull
