Replacing Deck Caulk


Teakdecking Systems SIS-440
Dug out some failing teak deck seams, taped the edges, put in SIS-440, used a putty knife to level the surface, and removed the tape before the caulk setup.  Got a great result.  The SIS-440 stuck well and seems the perfect durometer for a deck joint--not too hard and not too soft.  The color matches the existing caulk and the SIS-440 is priced under $15/tube.  What's not to like?
I bought a tube last winter and it summered aboard in the southern Florida heat.  Amazingly, the tube was still good when I used it last week.  Clearly, shelf life isn't a big problem.
