Sail Life - Rebedding deck-hull bolts using butyl tape
ฝัง
- เผยแพร่เมื่อ 28 ก.ค. 2015
- A couple of the bolts in my deck-hull joint have started leaking after 40+ years. Luckily cleaning and rebedding them is very easy! I use simple ethanol to dissolve the old butyl tape and rebed using new butyl tape. Good for another 40 years ;)

I purchased butyl tape at this place: www.pbase.com/mainecruising/bu...
unbelievable what transformation Mads made through during the last five years. Now he has a bigger boat, self confidence, a girl friend, and he actually makes funny jokes. Anyhow, I enjoy watching the old episodes.
Wife now.
Mads, great video! This is the first time I've replied to your channel but I've watched all your videos. I live in Kansas, that's in the middle of the United States. However My wife and I are just starting our 2 year plan/budget to buy a sailboat and move to the coast and become cruisers/livaboards. Your videos give me great inspiration and knowledge. Thanks so much for the quality videos!
I like that you showed the usefulness to yourself for making the videos to maybe later use for reference. My sons and I built a camper that slides into the back of a truck. It holds six kayaks, camping gear and can sleep 5 people when the kayaks are not inside it.
We took photos and video off and on during the process. Later we had to refer back to the photos and video to see where screws or framing were located. When I watch your videos, I feel inspired to edit something together as my channel has no videos.
When ever you remove anything that goes through your deck or hull take a few seconds for a very close inspection of the hole and its edges. All holes must be cleanly beveld and look very closely for minute cracks radiating away from the hole. A clean 45° bevel reduces the risk of cracks occuring and rapidly growing but on a 40 year old deck I'd even put a nice radius on the hole like is done on holes through glass.
Butyl tape is, like you say, amazing.
I've been watching your channel since around the time you bought Athena; So I'm very happy to have found a trusted source to answer some of my questions about butyl tape!
I've been using butyl and I'm on my 3rd good old boat. I keep running into silicone and household or marine sealers on the boats. I have had to take apart butyl joints that I've done and they come apart easily but were well sealed. I'm still learning to use it to its capability.
By the way... when I stow things away on the boat (and I know you've been working and making mess) I make a note of where it is. I list all the stowage compartments in a file on my iPhone and list what is in each. When I need something I look in the file. When I'm finished I put it back in the right place. It's a process I took from the Navy. There is a lot of stuff stowed on a ship and you need to know where it is and that it will be there when you need it.
Butyl tape!? The best. I purchased mine at the same place as you, and of the 6 rolls originally received, I have two left. Harmony is very happy with all of her new butyl tape beddings.
Another great vid! Fair Winds! Doug
Awesome! Thanks for the links. I'm planning on getting some of this when I start bedding fittings.
Mads your enthusiasm shows no bounds.
I was surprised at the remarkably good condition of that bolt you removed - after 40 years too.
I do not know how you will live with yourself, that job was so easy, you should have removed and receded all the bolts in the eve berth. You had enough Butyl tape.😀
Mads, great project (insulating the V berth); also enjoyed the isotherm unit install. I'll have to get one of those for my icebox. As for the V berth, my boat already has the teak slats....thank goodness. And thanks for allowing all of us to come along with you as you complete your project list for the boat. Good luck selling your house also. Ken in Orlando
Mads, your attention to detail in everything you do is amazing. I love it!! Great work😀
Sea Haul Thank you so much :)
Another very informative episode. Thanks Mads.
John (and Julia)
Great video Mads. Keeping the older boats dry seems to be a full time job these days. Just a friendly tip, a wire brush works great and is a pretty cheap way to clean bolts. There are also chemicals that do the job, but this job pertains to keeping liquids out of the boat, not bringing more in. I'm sure your dog will agree against more chemicals too.
Cheers.
As always, enjoyed the video.
I was not even aware of butyl tape, good video, thanks for making and sharing.
Robb's Homemade Life Thanks! I appreciate you taking the time to leave feedback :) Butyl tape is amazing. The entire deck-hull-joint in the ballad is sealed using butyl.
I bought butyl tape awhile ago, I think I know where it is. I am going to give it a try. One hesitation I have had is that I don't have a second set of hands to unbolt or aid in re-bolting. I thought this task required two people. I was inspired that you did this task alone. I am going to try re-bedding over due hardware on my sailboat this week. Thank you!
Most screws and bolts through the deck require two people to remove and especially reinstall, because you want to turn the nut and not the bolt to preserve the seal. It appears that the deck bolt you replaced was a carriage bolt, which has a square-shaped section just below the head that locks into a squared off hole and prevents the bolt from rotating while being tightened.
As always. Good stuff.
The toothbrush goes in the toolbox, they are *so* useful, and it's cheaper to keep the one you have than use your current brush each time you need to scrub something small.
was thinking the same thing
Will do. I have to re bed all the deck hardware on Spokojny.
I really do think you should have your own brand of butyl tape you love it so much!
Nice video and I hope you find a deep-well socket to use on the other bolts instead of the crescent wrench! Butyl is good stuff!
Great video Mads. I will look into the tape.
Dennis Cline Thanks :) Butyl tape is amazing :) Have a look at the two links in the description. One is a like to some awesome information and the other a link to the stuff I bought :)
***** Thanks for those links Mads, never thought about beveling those holes before.
You are making me feel bad for putting projects off because of being to busy sailing Mads. haha I like that butyl tape and I'm going to use it for sure!
Thanks for the video. I have heard of buytl tape but never used it. Of course, I need to get the sailboat first! :-)
Taking your advice Mads. I have ordered a roll of Bed-it Butyl tape from Hamilton Marine. I will let you know how it works for me.
Hi
You should check out my "tools" video where I show everything I use for my subway. You need a good 12 point socket set. I use this on all my engine and other parts on the boat, they grip amazingly well
Good to see you're moving along so well on your new sailboat!
I don't know if anybody has suggested this or not, but if some have failed in "40 years", then the others will too. While you are at it, you should replace them all, before they start to leak into your nice, new, finished V berth.
From the thumbnail I thought this guy was Michael from Vsauce lmao 😂
took me a while to find this vid again after 4 years... I was looking for the link to butyl tape as it seems to differ as to what it is from web page to web page. Wanted to find the OG..
Can I use Butyl tape on deck fasteners that are crewed in not bolted?
Great video. I am in the process of having my yacht re painted and when done will need to re fit all the bolts. My yacht is aluminium and most the fittings have no nuts and just thread into the aluminium deck. What is the best way of bedding these in to make them waterproof. Obviously using butyl may not work as when tightening the bolt it will remove most of the butyl due to the bolt turning motion. Any ideas?
Hi Mads
Great video.
Where did you buy it in Denmark / Europe?
Thank you for all of your videos!! We just purchased a sailboat and we will begin working on her next month. I know you are busy, but I asked you a question last week on your 2nd Isotherm video about your stripping and crimping pliers. If you get a chance can you let me know what brand they are?
Thanks,
Mike
What do you do if your v berth walls aren’t ripped out like yours in this video?
Great Tutorial - we'll be adding it to our website if that's okay with you :)!
Give white spirit a try also.
My friend, what is the exact name of the product you are using?Thanks.
Why did you not do all of them while you had easy access? Just a little forward thinking.
Good video Mads! I also did a video using Butyl tape on deck fittings, did you see it?
Butyl is religion!
Butyl is king.. never use silicone caulk you will regret it at a later date.
As a long time auto and aircraft mechanic learning about repairs on a new to me 35yo sailboat, it pains me to see an adjustable wrech and locking jaw pliers used on machined fasteners. Otherwise great info.
me too,but...it works!
I have searched now many times and for a long time and I cannot find a please in Denmark where you can by this butyl tape?
Please help @SailLife - as the link you have in the description in USA only it seems and I would like to just by it from a webshop here in Denmark :)
How much do you need, Mads? :) I've got plenty and I could easily spare a few meters. I haven't found a good source of butyl tape over here yet. The stuff I've got is from the link I the description :)
Sail Life well I don't know. My first boat so all is new to me. I guess 2 meters would be enough. If I can buy that from you it would be great :)
Let's write on Facebook messenger maybe?
@SailLife I actually found this yesterday, but I'm not sure it's the exact same. www.wattoo.dk/dafa-multi-sealing-tape-50-mm-5m-900400624?gclid=Cj0KEQjw76jGBRDm1K-X_LnrmuEBEiQA8RXYZ8L6ruKRdnzM0HxenrSbQo-DPGQzVlgee_1HgJfFQboaAo118P8HAQ
But if you have enough and you want to sell some of it, I would love to buy some, like 2 meters I guess. :)
PS: I wrote to you on Facebook Messenger.
Hi Mads, you may consider looking at the material safety data sheet before continuing your usage of butyl tape. Most substances containing the prefix "butyl" are toxic. See this site: www.smalleyandcompany.com/docs/msds/ADT%20RT.pdf
Well then don’t eat it. 😖
Title typo … "blolts" ;)
Craig Morgan Oops :) thanks ... I'll fix that right now :)
Hi Mads , I sent u a message the other day maybe it went into junk folder
Michael Juneau Hi Michael :) You got mail ;)
blolts?
sorry, grammar-nazy
h beek already fixed ;)
good
