Its not going to make any difference if some of the blisters are deep if the boat isn't kept in the water, whatever the problem is the damage has been done.

Re: Bubbles on hull after cleaning

Not encouraging but reality never is. Obvioulsy I don't have the time to redo this whole thing.

But I am considering, if this is not too idiotic, sanding the area (with small orbital sander) hoping the more serious blisters will pop. Then possibly use a two step thing to seal and repaint it. I found these products and they would 'appear' to do the job of keeping the water out and making it look decent again - if they are compatible. The cost would not be great because we are just looking at the bottom half of the side of the hull and transom area - not a tone of sq. feet. Maybe it will last because, as you say, we don't leave it in the water and it is not in salt water at the big lake. So reasonable on any level?

Re: Bubbles on hull after cleaning

The "right" fix is sanding down, using an epoxy barrier coat, then repainting with whatever bottom paint you want.... you can do it patch by patch or all at once, up to you.

I'd think it would be good to get it over with all at once, but maybe that's just me.....

Re: Bubbles on hull after cleaning

Its kind of a fix it right, or use it as is deal. If you do a half way fix on it there's about a 90% chance it will only last a short time, possibly not even until you put it back in the water.

Un-repaired blisters will change size with temperature and when in the water.

Re: Bubbles on hull after cleaning

So you are saying basically to sand all the blisters to the surface before putting the protective coat one on?

Re: Bubbles on hull after cleaning

I would say at this point do 2 things..

1. Break one open with the tip of a knife and see if something comes out.

2. Get your hull moisture metered.

It might be worth getting it stripped .. let it dry out .. then do your coatings. ( all depending on your meter readings ).

YD.

Re: Bubbles on hull after cleaning

Check the last pages of my first link for bad hull blisters ( the horde ). I'm currently grinding them out of my hull and just picked up my first 1/2 lb container of PC11 epoxy to fill them in.

Red..

Sweet job man !!!

Though it has nothing to do with this post as those are rivets.. make a new thread if you want...

Anyone want to say that the blisters are right at the waterline ? ... or notice that it does not look like a Normal scum line add that ruines the whole bottom ?

Thread is not only inconsitant..but hardly worth reply now..

So this chem just BLEW up blisters out of no were.. just WOW.. just it was nice before..now its just SHOT with blisters all over..LOL..

I could be wrong..but the posters pics for just adding chems and blowing that many blisters ( Right at the waterline ) is not normal...( but I dont think Im wrong ).

YD.

PS. reply IF you like.. I have never Ever seen this.. If you have then ........ Wow......

Re: Bubbles on hull after cleaning

I hear you. My goal would be no unrepaired blisters if I sand the entire area smooth before the barrieer coat is applied. I guess I'd need to experiment with what grade sandpaper it would require to smooth it all out evenly before applying the barrier coat to fill in any and all holes that appear. I assume I'd need to then gently sand the barrier coat after it drys before the paint goes on second so that it goes on smoothly.

Re: Bubbles on hull after cleaning

Well YD, I'm new at all of this so you can doubt and LOL if you like since this does seem so off the wall. Might not be so silly if it were your boat. but that is exactly what happened all within a few hours. I thought I was done when my father-in-law came into the house and said, "what are all those bubbles where you just cleaned?" My son was also shocked.

Since this is 'not worthy' of any more comment I'll apologize and not bother anyone for further info or advice. I'll just do the best I can with what I have gleaned from a few here and consider the subject officially dropped.

Actually, those are not rivets...my boat is glass. After reading up on blisters
http://marinesurvey.com/yacht/BlisterRepairFail.htm, it's possible that the chemical used reacted with the paint and caused these problems.

Re: Bubbles on hull after cleaning

RedFury...

Sorry man.. I just looked at the last post on the thread and saw how it looked like rivets.. My WAY bad.

And thank you for not Slamming me as you had every right to . It was a lack of looking at it on my part..

Breck...

Dont let Me put you off please..

Please dont take my post as a recommendation for the Forum.. there are some smart cats here..and Trust me when I say will spend HOURS of Research for others just to help.. The Forum is Extensive more then most realize..

Unfortune has it that I have to deal with people that BS why..what..how..when and where almost weekly..

Still .. the Diagnosis would be that there were allready blisters present..and you didnt see them because of scum or whatever..

I could not believe that the product would attack your coating in the way ( consistant blistering ) that you suggested. Again.. I have Never Seen this happen like your pics show.

Now then..

With your blisters.. Your going to have to strip down to where the blisters starts from. I still suggest you get it metered. Then do your epoxy barrier coatings ( you May..and I Stress MAY be able to bridge your popped and sanded blisters with epoxy coatings depending .. but not recommended here ).

Again.. You are welcome here ( though I might not be soon ).

YD.

PS. no mods have personally talked to me about this..and I will never Edit my post to make me look less of an *** then I can be at some times

Re: Bubbles on hull after cleaning

No worries... wmbreck......I don't recognize anything from your photos that would make me.. or others.... to jump to any catastrophic conclusions.... If she were mine....I would do some sanding in a suspect area down thru the color....to the laminate... and post photos of your progress. Were are with you.

Re: Bubbles on hull after cleaning

Y, Dr. No problem. Forget aabout it. I'm simply frustrated and mad at myself for doing something perhaps stupid. I was thinking it through again and there was one variable I never thought of.

I had no hose near the boat to rinse the solution off. I did have the big can of water that I had used to run the motor to get the gas out of the carb for the winter. That means some oil in the water, So "maybe' that reacted with the acid 'OR' more likely did not rinse the stuff off as it appeared to. So this may have been my fault unknowingly. That is why I kept saying that the hull looked flawless even close up before the blisters just jumped out in a few hours. It may have been near the same as not rinsing it or not fully rinsing it. Does that sound even remotely possible?

That is why I'm so irritated that I may have to now spend a few days of my precious vacation time sanding, sealing and painting this instead of enjoying it. I guess I need to put a nice electic sander as item no. one on my Christmas list

Thanks again for the input.

Re: Bubbles on hull after cleaning

YD, I wouldn't slam someone unless they were attacking me repeatedly, so no problems here...everyone makes mistakes...even doctors.

They do look like rivets on first glance though, there's so many of them you'd think I own an starcraft!

I agree with the consensus here though, sand them down and find out exactly what you are dealing with.

Re: Bubbles on hull after cleaning

Just a quick update on my 'blistering saga' above that I sought advice on a few months back. As a refresher, I had used an acidic cleaner on thye hull from a local marina and somehow must not have rinsed it sufficiency or somnething else and the entire side from the waterline down blistered. I was considering options and got tons of advice here on what I should and could do.

Anyway my wife's uncle was at the lake last week and came home and asked me why I would mess a with something so minor that you had to get 2-3 feet away to even see it? I thought he was going more blind. But we just got back from closing up the cottage last night on lake Ontario for the winter. Upon reinspecting the bubbles/blisters, it seems that they have all shrunken down by about 50% meaning that the majority are very small (just pimple sized) Again, only one or two went through the white coating to where you can see something a darker area (fiberglass) underneath. I even felt under the cover on the outside of the transome and that seemed almost perfectly smooth? I was stunned. I do recall one of you guys saying these things might shrink back down in time.

All of that to say that I might leave it alone (as a few suggessted) and see what happens after fixing the few spots that seemed to go through to the FG and any others that might look like they should be "popped", resealed, and painted. Again the boat does not sit in the water at a dock and probably will see 20-30 hours of use for the summer.

Any additional thoughts are welcomed.

Thanks again for all the insight and any other comments based on what I have just shared.

Re: Bubbles on hull after cleaning

Well, there is something to say about leaving things alone and seeing what they do

Unless you are in a huge hurry to go balls out sanding and painting, I'd guess I'd just keep an eye on it and take care of it only if it becomes either a large cosmetic issue, or something you worry about water intrusion from.
