The best deck seam caulk

[chad.lawie]

When it comes to caulking seems on a teak deck, what do you use or think is the best?

Personally I'm going with a 2-part poysulfide.
According to this website:
How to maintain and caulk teak decks on boats.
2-part is the only way to go, the site also recommends going with the cheapest because they are all the same anyway.

any thoughts?

Sikaflex is my personal choice for bedding but not really up for a teak deck. You need something tough enough to handle the UV / weather. Sikaflex is more behind the scenes appropriate.

The two part is probably the best if not only choice. It's the application part that is the real chore. Your link seems to me to be pretty complete. I have never heard of a magic solution that was easy. Nothing new and improved has come up in recent years that I know of.

Single part oxime cure .... http://www.teakdecking.com/caulking%20products.htm
Used on the mega-yachts, etc. Doesnt sag during cure, etc. - less 're-work'. Bonds extremely well but definitely needs a bondbreaker in the bottom of the groove. No mixing (with its resulting mess).
Just a 'very' happy user.

Available in the USA from the 'usual suspects': Jamestown Distributors, etc.

Definitely POLYSULFIDE (though 1-Part is probably as good as 2-Part – and certainly easier).

I like
3M #101 (1-Part)
and others recommend
Detco GS1-302 Deck Caulk (2-Part)

i used the two part on the teak decks on one of my boats, laid new deck, used the primer, mixed the poly and put it in the tubes was suprized at how easy it was. not very messy if you pay attention. the only thing i would do dif. is tape the seam edges before the pour/squirt. i did have some dimples from air bubbles, but that was the only prob. i had. what ever you use make sure you over fill the grooves slightly because the stuff does shrink a little while curing. once it has fully cured all you do is belt sand diag. across the grain to flatten the high spots then go with grain to remove cross cut from belt on wood. good luck
