I'm On A Boat- Fixing Fiberglass Blisters
HTML-код
- Опубликовано: 6 сен 2024
- A guide to repair and fixing fiberglass blisters on boats. This is a common problem among sailboat hulls produced in the mid-seventies. Narrated by a Camper Nicholson 31 owner completing this project himself by prepping and filling his blisters with epoxy resin. An informative how-to on this topic with demonstration and step-by-step instruction.
One of the most factual "boat folks" on YT I've found. Speaks like an Engineer ! His history of blistering is spot-on fact
Personally, I avoid pressure washers on fiberglass: the huge pressure differential logically encourages water penetration.
Acetone and a heat gun per blister is what works for me (minutes not weeks)
Also, the difference between paint blisters and de-lamination blisters is a big one.
If the repair dent is more than 2 layers deep, I use fiberglass cloth (fine) to rebuild the structure. smallest is deepest then larger as you work out; all in "single cure" mode with compression.
West System epoxy, 404 filler, and Splash Zone are reliable.
Re-coating the entire bottom is usually not needed. Spot repairs work fine. (unless the entire bottom is stripped to bare 'glass)
Cheers
Thank you for that additional detail.
This is an excellent video. Top rating in my book. I love it: "Blisters come back..."
Hi! It's been a few months but I thought you would be interested to know I am working on more epoxy and hull painting videos right now :) The Camper Nicholson 31 featured is finished and being launched today!!
The Iranian hostage crises took place from November 4, 1979, to January 20, 1981. Do you mean the oil embargo by OPEC. That took place in 1973.
Came here to say the same thing. Good video though.
How ironic, was just talking to a gentleman that has a boat on my dock who said the exact same thing about the oil shortage and how my 1965 wayfare may not be to bad, just bought her and was thinking of having her hauled out as I have no info on when she was last pulled out. Now I know both of you are as knowledgeable as you appear to be, I love affirmation!😉👍👍👍
Hi! I have issues with just the gel coat blistering on my deck. Should I clean, seal, and re-gel it over. Or could I just use epoxy rezin and thickener to level out then paint... Instead of gellcoat... Thank you. Your video is short, sweet, and answered 95% of my questions!!!❤
Thanks a lot for this video, you covered everything I needed to know, plus the three blisters I have on my boat don't seem so bad after seeing how many you dealt with.
Great video ! My Camper Nicholson 44 had the same problem with blister , now is time to paint the top side myself .
Thanks! Yes, we get on HMS Bounty this weekend and will try to share as much as we can.
Thanks, he taught high school for 36 years.
Thank you very much very helpful I just got a 1979 mcgregor sail boat and it's goat some blisters and spider cracks and what not but thank you again 👍
Great explanation of the blistering process.. Thank you
Polyester not epoxy and filler should be used to fill and fair using the good stuff isophthalic resin not the orthophthalic resin that was inferior and used on that boat. Because then you can Polyester gellcoat. If you use epoxy to fill you will have to epoxy gellcoat and that is costly and not necessary. Also some of those blisters need fiberglass cloth or chopped strands to structurally repair all that glass that was removed. A lot of work, so if you are lazy like a lot of people posting here forget it, this is a job for a worker...
Pollyester or vynlester gellcoat will not stick to epoxy well trust me ...
I can never understand why on a very expensive item like a boat why high quality materials are not used. What is another grand or two on a $200,000 boat?
Hi, sorry for the delayed response. I believe it is possible for both types of recurrences, but so far this particular boat has not shown any signs of new blisters.
So good...I learned a lot. Thanks for sharing your knowledge.
Yes, he has an amazing knowledge about sailboats. Thanks.
great video! maybe one day we will meet on the water.
Great Video, really taught me something useful; well done and thanks a lot.
I found this extremely educational, just one query though; when you say blisters come back!, do you mean that new ones appear in other locations or can they re-occur where you have previously removed and patched?
Was wondering the same thing
What a wonderful educational video. I am a huge fan of you guys. Is this man your father? Is he the one that was so instrumental in rebuilding your Vega? If he is your so lucky I would have loved to have him for a mentor. Just think of all one could learn from him. I wonder what he thinks of Nauticats. Especially the 33. I think the Fins really know how to build boats but would love to have his feedback. Is there an E-mail he would accept questions from? I have so much to learn Thank you so much
Thanks for the video. I am doing the same job and have a question.How deep you can go in the hull wheh treating the blisters this way ? I believe the hull is 10 to 20 mm thick depending of the area , how many mm you can take out?
From experience epoxy does not adhere to the polyester substrate well, may blister again. Vinyester is the better option.
I learned alot from your video.Thanks.
Thank you wiseman
nice video thanks. pls think about a lapel mic .
Nice job, thanks for sharing.
Unfortunately we will probably be off sailing when he reaches that step.
No one should grind fiberglass without a mask with HEPA filters.
Only if they want to survive. Or run more than 50 feet.
On one side of my boat I have hundreds of blisters. When does one use chopped fiberglass or 801
personally, i never use "chopped 'glass". Use cloth and try to keep the resin/cloth weight ration close to 50:50. If the repair is more than 2 layer deep, I use cloth to rebuild the structure and depth. All layers in one cure, compressed. Cheers
@@solosailor222 Thankyou
Blisters come......I heard that in Health class so many times.
It's not going to dry
Hi, I'm having my 1982 Nicholson 31's hull peeled & reglassed as it has Osmosiscovering the entire hull & rudder, I think this boat is worth doing it. I have found itdifficult connecting with fellow Nich 31 Owners as the Association Website appearsto have been abandoned, can you help? I've only had her a couple of months and I would like to talk to other owners. Keep the great videos coming! Regards Jeff.
Hi Jeff, I believe the Nich 31 group has recently come back after a hiatus. Please reach out to these owners via sailmotuiti (dotcom) Best, the Howertons
Love how he ends this with..maybe its all for naught.
Good stuff. But get the history right. The Iranian hostage crisis was in 1979 and had nothing to do with the rise of oil prices in 1973...
Jean Baillargeon doesn’t change the point at all 👎🖕👎
U remind me a little of the guy teaching me
Better wear a mask while grinding ...
best thing to use is Pollyfilla.
Using Vinyl Ester is ridiculous!

Be more professional about your audio please-maybe I'll be back.
So, all that labor, lay time, cost of materials, strain on your relationship and you end with......"I don't know if it will work, blisters come back" What's the point then? Huge waste of time and so is this video!
This video is actually really helpful, but let me explain something. Interlux primer paint applies micro plates to create a barrier which increases the distance the water molecules have to travel in order to get through. Unfortunately the water molecules are very small and extremely determined that they will eventually work their way through any barrier, no matter what you use. It's going to happen! The micro plate technology deters that problem, which is what we want. That's why you should apply more than 2 layers (alternate between grey and white primer) 4 layers should provide optimum coverage Interlux say, but if you have the time and paint, it certainly won't do any harm to have 10 or how ever many you want. Hope that helps with your project.
Right on...good response. Thanks David
