Toe Rail Recaulk
Toe Rail Recaulk
I'm at the stage in my chores that I'm digging out all the old caulking (3M 101 at the time - it's no longer available) to recaulk our toerail. My fiberglass supplier, with a long history in the boatbuilding biz, is recommending Bostic 940FS. Water cleanup and tooling, it looks easy to work with, with a 20 minute skin time.. I'm having some serious questions as to the wisdom of using this material. The 101 I'm taking out in some places is very resistant to removal (others pull our fine with the V-shaped tool I'm using to get under the center and catch the edges in one pass). However, that's merely caulk, and not an adhesive. Knowing 5200's reputation for later removal makes me think twice. I hope I don't, but realistically I expect that at some point in the future, I'll be recaulking the toe rail. Whether I'd be able to get this stuff out without treating it (time, money, ?? impact on the paint/teak) is keeping my attention right now. Has anyone used this stuff (Bostic 940FS) to say how it behaves, particularly in having to remove it? Secondly, if you've had years of experience (how does it hold up?), if not this, what do you use which is currently available (101's not)? Thanks.

L8R Skip The majority seem to be using either 3M 5200, or it's quick setting brother, or one of the Sikaflex sealants/adhesives. Bostic 940FS has a tensile strength of 255 psi @ non-stated elongation, but over 100% 3M 5200 has a tensile strength of 700 psi with 1350% elongation before break. The Bostic cleans up with water, the 3M cleans up with 3M cleaner, white spirits, diesel fuel, etc. But a question. If you use 5200 why do you think that you would later be recaulking?

Except for installing plastic windows, where I use Sekaflex 295UV along with the appropriate primer, I've always used 5200. for mounting stuff and in my experience it is reasonably easy to remove items installed using it. On the other hand, if one installs, say a thru hull or a winch, one usually does it with the idea that it shouldn't come adrift so I've always view the argument that "Ooooh it is so hard to take it off" with a certain amount of awe. Who wants a thru-hull to come off easily :-) By the by, I've used 5200 when mounting stainless hardware on aluminum when I didn't have anything else. several years later I had occasion to take the fittings off to repaint the spars and the screws came out with a common screwdriver and there was no signs of corrosion anywhere.

I've used MEK, kerosene, white spirits; practically everything but water and it all worked. On the other hand, soapy water works well to smooth it without getting your fingers all sticky :-) Cheers, Bruce |

Essentially he is trying to seal up an external seam between the toe rail and the deck as I understand it. That is a somewhat problematic application because it depends on adhesion to exposed surfaces for effectiveness, and it gets full exposure to sunlight. We've had good luck with the 3M 4000UV on our front widshields which have a similar issue. Nothing is truly permanent in that application but we've been getting 2 or 3 years on average. |

... Toe Rail Recaulk I have been waiting patiently to see if there were any real sailors here and apparently there are NOT. Real sailors would know "toerail" is one word. Duh! You're welcome! Wilbur Hubbard |
