Re: Bedding Deck Hardware With Butyl Tape

BubbleheadMd, I too am faced with bedding the grab rails. My boat doesn't have grab rails
inside. My plan is to apply the tape to the rail where it mates with the cabin top. I'll clean the teak with acetone then apply the tape, cut out the hole for the screw, set the rail on
the cabin top, then screw it down. I've done this to a couple of cleats (bedded the screw heads there), and tested it this morning. YEAH no more leaks.

Mostly my problem is hardware where you can't wrap butyl around the head of the bolt or screw because the hardware is very tall, and far off of the deck.

For example, I have teak grab rails on the inside and topside of the boat, that sandwich the cabin top between them. The bolt head is on the INSIDE of the cabin, in the interior grab rail, it penetrates the cabin top, into the topside grab rail, and into a threaded insert in the top of the topside grab rail.

The best I could do, was snug them down close to the cabin top surface, and wrap butyl around the bolt as best I could, and then finish snugging the grab rails down.

This is not optimal, because the bolt rotates, disrupting the bond of the butyl tape that is wrapped around it. (which is why I get things partially bolted, and close to the cabin top before applying the tape.)

Still, it seems to work and I have not had any leaks. I have a few such installations, and this is frustrating.
So it only lasts 15 years instead of 30.

Hey, I wouldn't complain about that. I'm just trying to make sure that it's really sealing the cabin top and not allowing water into the core.

Punch the bolts up from the cabin and install long butyl cones. Now carefully drop the rail over them (two people best) and get the nuts started. Now just slowly and evenly tighten them all..

Alternatively use threaded rod pre installed in hand rails and acorn nuts on the inside....

What does it mean if there is brown goo coming from the location?

Re: Bedding Deck Hardware With Butyl Tape

After getting some butyl from Maine Sail, I've pulled a stanchion and some of my chain plates. Mainly the ones the PO had buried in silicone. Suspecting there was a REASON why they had silly-cone all over them, I pulled them before we paint the deck and sure enough, not a spot of bedding. One I had bed with 4200 just after we got the boat and one was good and tight and had what appeared 4200 under it. The other two I pulled, checked for water (unbelievably they were dry), and rebedded with butyl per MS's instructions. I was pleased with the results. I'm confident they will stay dry for a long time. Adding pictures for the benefit of those who might need pics like I do!

Re: Bedding Deck Hardware With Butyl Tape

Sorry to bump an old thread, but after reading this post I'm a little confused.

I've explained my question here:
Confused - epoxy or sealant/tape? - The Hull Truth - Boating and Fishing Forum

But haven't had any replies as of today. Could someone on this forum (I'm new here) please help me out?

They are two different steps. The butyl is the sealant between deck and fitting. The Epoxy is to seal the core in case a fitting ever leaked. Most boats, like 98%, do not come from the factory with sealed cores where bolts pass through..

If you want to seal the core you do that first, then bed the fittings.

Re: Bedding Deck Hardware With Butyl Tape

In the sikaflex documentation it recommends using a thin spacer when bedding items down to prevent all the sealent being squeezed out. Is this a good idea with butyl?
