[Rhodes22-list] Portlight re-sealing

[Larry Gioia]

 Oh gosh, 14-21 days to cure - I'd mess something up during that time.

 In the past I have used marine 100% silicone and the portholes and port lights never failed while I owned the boats. I just finished reinstalling a 1 X 3 port in my big boat and the mfg was quite adamant that I use Dow 975 silicone sealant. It has strong adhesion (60 psi?) to fiberglass and lexan /plexiglass. Down side it takes 14-21 days to cure. I should have read the data sheet, so we are here in Sunny (sort of) Fl for a couple more weeks until we can head south east a couple hundred miles. If you don’t mind the wait it might be the best product to use. Chris Geankoplis Enosis

 Scott, Roger, Michael,                      Thank you!  I had searched for portlight, but searching for just port or Beckson brought all these back - looks like all-silicone is the answer and I see the steps now.   And yes, on my '86 water sits in the forward-facing ones also - There is a canvas cover that snaps over both of them - seems to help somewhat.                   Larry

 Larry,

A quick check of the list archives brought up this August 2020 post by Graham Stewart:

    Regarding the use of silicone for ports.
    
    Beckson, one of the largest manufacturer specifies that silicone SHOULD be used :
    
    Their installation instructions are found here: https://www.beckson.com/installport.html 
    
    "Choice of Sealant:
    There are many brands of caulk, adhesive and sealant available in your marine chandlery 
    or hardware store, but be wary, not all are like. Many are for specific applications and may
    contain solvents that are destructive to thermoplastics. Chemical solvents should not be 
    used for clean up.
    
    Beckson recommends 100% silicone sealant only. Availability of silicone varies regionally.
    Please contact your sealant manufacturer for the most up to date information with regard 
    to materials and compatibility. Silicone has been around for nearly 50 years without sign 
    of failure. Most other caulks and sealants fail after 10 years.
    When a port is installed properly, silicone works best for years of enjoyment.
    
    Sanding previously caulked areas:
    Previously caulked or sealed areas must be sanded in order to remove the old caulk. 
    If not removed, a strong bond will not occur. Surfaces may appear to be free of caulk to 
    the eye, but residue may still be present on the gel coat. Sand lightly with 220 grit paper
    to prepare for the silicone sealant."
    
    Check with the port manufacturer before deciding. Butyl is probably a safe choice but 
    while it is an excellent sealant it is very weak as an adhesive. On a slightly curves surface 
    that adhesive quality might be important.

Larry,

Check the archives for a step by step article on replacing a Beckson opening port.

>>> Hi,  I think a few of the portlights on my '86 R22 are leaking.  Image that after only 34 years in the Florida sun.  I searched the listserv and saw emails from 2008 suggesting to use BoatLife Sealant and to clean with acetone beforehand to remove wax.  I was hoping Peter would have a video about it, as his videos are always great, but didn't see one - his remanufactured Rhodes probably hasn't needed it yet.    Any suggestions other than that?  I'm guessing they're a bit tricky to remove.  I see screwheads on the exterior but nothing on the interior, unless the interior ring pops off.  The BoatLife website https://www.boatlife.com/product-category/boat-caulk-and-sealants/   shows a bunch of different products - lifeseal sealants, life-calk sealants, life-calk 2-part sealant, liquid life-calk sealant, liquid lifeseal sealant, marine silicone rubber sealant  (I assume LifeSeal Sealant), available in tubes and cartridges (probably either).
