We have started on the teak deck project by gouging out the deck seams
and replacing them using the methods suggested by Bryant Vann, Captn Wil
and others in the archives. But the marina did not have 3M 101 in
black. Instead they had a new product from 3M named Teak/Wood Seam
Sealant. The label certainly read as if it were the proper thing for
replacing the seams. We contacted 3M to find out what this new product
was.
The answer came back that: "Teak/Wood Seam Sealant (pn 06570) is now
preferred over the 101 for sealing teak decks (and a bond breaker at the
bottom of the seam is still recommended as the standard procedure).
The new material is a polyurethane (101 is a polysulfide) and the teak
primer (pn 06533) is still recommended.
Another surprise: "4200 would be a suggested product for bedding
through-hull fittings (preferred over 101). 4200 can be used above or
below the waterline."
The only warning with the literature (other than the note on the bond
breaker) is that it must be protected from direct sun and rain for eight
hours after application.
We have done one seam with it and it handles like the 101 that we have
used previously. It may even be a bit more fluid and easier to flow
into the open seam.
