Bottom paint question

I bought a new Hunter 25 last August and it was only in the water for one month. When the dealer hauled it out and pressure washed it alot of the bottom paint flaked off. Unfortuntley this dealer is now out of business. I am forced to paint the bottom myself and was wondering if I should lightly sand the bottom before applying the new bottom paint. I know Hunter says this voids the warranty but I cant think of any other way to properly prep the bottom. Any help would be greatly appreciated. I was thinking that possibly a light sanding with just a scuff pad might do the trick.

You Got It

Mike- First, before you do anything. Wipe down your areas that you plan to scuff up with Interlux 202, this stops you from sanding in the contaminants. After this is done scrub/scuff these areas and wipe down with 202. Then roll on your paint. Best of Luck. Rob Hessenius

Rob has it right...

... but if you don't know what the old bottom is, or can't find out from the dealer or anyone else who might know, you "may" have a compatibility issue with whatever new paint you plan to use. Most paint makers have compatibiity charts on their websites. Given the high price of bottom paint these days, it is worth making sure your new paint is compatible with the old stuff (which you've got to get it to the point of being either off the boat or well-adhered by whatever means you choose). If you really cannot determine what is currently on your boat, it may pay to invest in a gallon of Interlux Primocon and put that on first as a primer/transition coat. Good luck with the new boat.

sand only where you want the paint to stick

Advice seems crass, but its true: sand well and prepare surface for new paint. But do, do find out what is on there now, as some are not compatible. The up-side is that, from now on, you will know what kind of paint and job was done on your property.

NO NO NO don't sand it......

Your paint was applied improperly. (no de waxer, no primer) Normally, I'd call the dealer and demand they do it right this time. The next step would be to call Hunter and get their input. It's still a new boat. If have to do it yourself don't void the warranty by sanding. Use a de waxer, if necessary, then a no sand primer. The primer sets up a chemical bond between paint and bottom. This link will explain the process of prepping a new boat bottom. Again....Don't Sand!!!! http://www.yachtpaint.com/USA/hotlinks/fiberglass_paintguide.pdf

Compatibility Odds

Mike- The heavy favored odds are that you wont have compatibility issues in your location of Massachusetts. The only issuesc would arise if you have VC or Pettit/WM FW-21. No way would a dealer in your area coat it with that. Just rough up the area that still has paint, just for the bond. Wipe with 202. Rob Hessenius

Light sand is OK

very light. Sand mostly the bottom paint and don't chew up the gel coat

Throw it back on Hunter!

Ask them what you should do. Bottom painting is really pretty simple. Let them tell you what to do. My guess is the dealer used a one year paint and neglected the initial prep work or the power wash was excessive. The other thought is that it is water based bottom paint. Try to find out what the dealer used. Not all paints are compatible r.w.landau

So far no one has suggested that you read the

label on the paint can. all of the questions that have been voiced here are answered in that short piece of prose. Thousands of dollars of research have gone into the products and the method of application but the most frequent complaint I hear from people that sell paint is the people that have trouble with the paint haven't read the label.

They never prep the bottom right

it is really hard to get all the mold wax off the hull. There is aways a few spots they miss. I can be a big problem if they really dia crappy job. Paint will keep popping off for 20 years everytime you roll on a new coat!

Waffle , I read the preparation instructions for

for removing manufacturing wax from a new hull. You need a barrel of clean rags, a special solvent dispenser can, excellant ventilation. AND an awful lot of dedication.. I think that I would not paint the bottom the first year.

It happens...

Most likely the paint was Petit Trinidad 1275 blue, if a hunter is new and has bottom paint on it, it most likely is that color. It is the same paint that Hunter Marine paints the bottoms with in FL. The dealer probally had some laying around and painted it with that. Is there a light grey paint under it? If there is, it is the no sand primer that Hunter uses that is junk. The problem is that if the boat doesn't go into the water 30 days after it is painted, it will flake off sitting on the beach. If your going to do it yourself, go to www.yachtpaint.com that website is so helpfull at painting you won't have any questions. btw, not for noting, but did you try contacting other hunter dealerships?

Do not let the warrenty lapse

I would find out from Hunter what you need to do while keeping the warrenty valid. This would be my first priority.

Bottom Paint and Hunters

I have a friend who has a Hunter 36. One year old. We are leaving next Wednesday to take it to over to Pennsacola to have the bottom done. Whatever was put on his is about gone. I don't know what they used, but the standard here in the warm salt water is Trinidad. The paint on his is light blue. If it is Trinidad, it certainly was not put on like it should have been. It appears to me to be more of an ablative paint than a hard paint like Trinidad. I don't know if it was applied by Hunter or the dealer. Those Hunters sure are pretty inside though.

Ross, what good would that do?

not painting the bottom the first year would do not good at all. The only thing that would do is require an acid bath the next year. I don't think it would help with the hull wax problem. The wax would still be there next year. I would hope the acid would take it off but I am but sure. You could only do this in fresh water. You have to bottom paint in salt water to keep the barnicules off.

I am not sure about why you wouldn't paint it the first year but I know Ross is right about lots of rags. Keep changing them for a clean one. Most people forget to change the rag and they just end up smearing the wax all over the bottom. I do agree that the first step would be to call hunter. It is a new boat and they need to make it right but we all know how that can go. If you have to do it yourself ask a lot of questions, read the tech sheet for whatever you pick and it will tell you exactly how to put it on.

No bottom paint on my new 25

Mike, While this does not address your issue, as I expect you are in salt water, I thought I would share my experience. My boat had been in the water for the last year (fresh water lake, very warm temperature). I pulled the boat last week and, of course, it had lots of green slimy growth on it that looked to be about a half inch thick. I power washed the boat and got a good portion of it off. That left only the chalky film and a real bad crusty line at the waterline. I then sprayed the boat with muriatic acid (cut down 5 to 1 with water) and rinsed it well. I had to do this a couple of times. The boat, after being in the water for a full year, now looks absolutely brand new again. The bottom is as smooth as it was when new. For me, putting bottom paint on, in the manner Hunter requires with no sanding, appears to be way more maintenance than just cleaning it well. I expect I will have some disagreement from others, but I can't really see any reason to bottom paint my boat at all.
