I'l support: Awoid silicone and use tape.

Using tape is a must. But why the aversion against silicone? I mean, it's
not the ordinary silicone houshold stuff we're talking about. This stuff is
specially designed for decks. I remember an article in Woodenboat about this
and they where very enthousiastic about it.

I guess I have a general aversion against silicone on boats. This is based
on experience from 20 years ago with some marine silicone products, that I
didn't like.

I realise that I'm probably not up to date on this subject. I'll look
further
in to it. Until then, forget my advise against silicone for deck seams.

....But then again, nobody has even 10 years of experience of the new
silicones.

Glenn, having seen your boat built from the start (virtually) I would hate
to see you ruin the deck with some non-proved new wonder goo when a known
and long-used 2-part polysulphide would be a safe alternative.

Everything I know of wooden boats tells that silicone should be kept far
from wood. If you start using silicone there is no way back. There has
been enough bad examples of miraculous new products failing after a few
years. Your boat is a pretty big testfield for expensive failures...

If you can find some installed examples to check the finish of the
seams, directly, you may find differences significant to you. I can't
speak directly to your question, but I have found a great variety of
appearance in caulks after cure - beyond the obvious coloration.

Rutu' teak decking will have about 1,100 lineal feet of seams. Based on
the manufacturers' coverage figures that will require 4 gallons or 60
cartriges of caulk.

The candidates with estimated cost for Rutu's decks a
Detco - 2 part polysulfide & primer + cartriges - $580
Boatlife - 2 part Polysulfide & primer + cartriges $540
Maritime Wood Products - one part oxime silicone - $510
Teak Decking Systems SIS 440 - one part silicone - $450

I am leaning strongly towards the silicones because there is no mixing
or cartrige filling and you can stop at the end of a cartrige without
wasting the rest of the gallon. Both silicones seem to be highly
recommended with the TDS product getting the most mentions.

Does anyone have experience with either?

I've heard a lot of good stuff about TDS' stuff. I've used 3M's product as
well with good success. Can't remember the number, but it's labeled "teak
deck seam/sealer" or something obvious like that.

No experience with the silicones. I'd really try to find from people who
have used these products for several years in tropical weather before using
them (though I shudder at the thought of that much caulking - have you an
air operated caulking gun or can you rent one?)

I do know the 2 part polysulphides have an excellent repuation.

Don't forget to use the bond breaker tape on the bottom of the seams and the
appropriate primer if you use the 2 part stuff.

Glenn, We highly recommend TDS SIS 440. We did the deck of our 42-foot
a few years ago. Easy to use, works great. We're very happy with it.
And this is after a disastrous experience with Boatlife.

Before we did the whole deck, we did the fantail with samples of a
variety of products. TDS SIS-440 was the clear winner after a year of
use and weather. We were prepared to pay almost anything to not have
to do the job again anytime soon. So cost really wasnt a deciding
factor. Performance was.
