Likewise don't use 5200 topsides - good for thru hulls, very difficult to remove. I am planning to bed everything topsides with 4000 however butyl tape is being suggested by several folks.

Re: How to waterproof holes in the deck?
You want a sealant that will flex a bit without losing adhesion. I would use butyl rubber tape. The tape is easier to use round cord-like butyl. You can occasionally find it at the hardware store but most RV stores have it or online.

The Butyl rubber tape I'm finding is 3/16" thick. Is that the right stuff? It seems terribly thick and would hold the stanchion away from the deck by a enough to make them wobbly. Really sharp looking boat you have too, you have some amazing skills. |

Re: How to waterproof holes in the deck?
Having used 5200 under railings ONCE ! I learned the Hard way.I fixed the leaks no Problem!! but 5 yrs later work had to be done in some of the areas repaired with the 5200. All I can say is, Maybe if your gonna sell it, but if your gonna keep it use something else !! It makes for a much harder job getting things apart! Just saying 5200 is for below the water line!!

Re: How to waterproof holes in the deck?
Please read the following photo essay on how to properly do the job, and DO NOT use 5200! Or Silicone!! Read the essay and I believe you will find butyl tape is the only way to go, and at the end of the essay there is a paypal link to buy the right size tape for the job. I just got some in the mail and delivery was very prompt. It is very rare for a true expert to divulge their "trade secrets" in such a thorough manner, refreshing! 5200 is referred to as DEVIL'S GLUE ha! The advice above on having adequate backing plates is a good idea.
This essay was one of the best written and most complete essays on ANY DIY job I have ever read, (and I just finished gutting and remodeling an 1853 farmhouse so I have read hundreds of them lately!)

Re: How to waterproof holes in the deck?
I am facing an analogous problem and I would welcome suggestions.
I am about to install a chain washer with the intended outlet to be to port of the windlass - a Jabsco flush quick connect hose fitting. I am not concerned with sealing the hole to protect the core. No different from the measures when install the windlass or the foot switches. The issue is how to seal the hose which is coming from well aft of the anchor locker entering it from essentially the V berth... the hose will run under the bunk. The anchor lock is wet, has a large week at the bottom and fills with water when the bow drops into a wave... and I do wash it out with a hose to get all the mud off the chain which drains through this weep hole. The penetration into the anchor locker for the wash hose will be quite low... I don't want to run the hose visible in the V berth.. so under the bunk hides it nicely. But it also means it very low in the anchor locker and could leak. I can't imaging sealing hose so perhaps I have to use some sort of thru hull ... but I need to connect hose to both sides. Or maybe epoxy in plastic or brass pipe and thread on hose barbs connectors on each end... and reinforce the pipe with a layer or two of plywood epoxied in. Since there is chain there it seems it should be brass rather than plastic pipe. How do you make a water tight penetration in a bulkhead for a hose? |

Re: How to waterproof holes in the deck?
I've removed deck hardware with 5200 or something like boat life... I would suppose it depends on how much surface area is involved. It's strong but if the surface is not perfect for the bond the bond can be broken.
