Replacing Deck Caulk


Teakdecking Systems SIS-440

Dug out some failing 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 set up fast, stuck well, and seems the perfect durometer for a deck joint--not too hard or too soft.  The color also matches the existing caulk.  It's also priced under $15/tube.  What's not to like?

I bought this tube last winter and it summered aboard in the southern Florida heat.  Amazingly, the tube was still good.  Clearly, shelf life isn't a big problem.
