View Full Version : Chainplate caulking

I'm looking for the BEST caulking for the area where the chainplate comes through the deck. This seems to be a constant source of a fresh water leak.

The best approach is to make an escutcheon or plate cut out to slip over the chainplate and screw it down bedded with Life Caulk or bedding compound. The escutcheon can be wood, brass/bronze or stainless.

Mine has a high quality two-part polysulfide. It's held up for lots of years.

I do have a plate where they can be applied. Two part it is.
Thanks, mariner

The best solution to leaking thru-deck chainplates that I have found is to make your own from material like phenofiber (tufnol if you are on other side of the pond) about 3/8" thick. Make the hole so that there is about 1/8 clearance to the chainplate on all sides plus make a small chamfer around the hole on the bottom. Use a good flexible caulk overfilling the hole and screw the thing down. The chainplate will have room to flex without breaking the bond and water can run off with no chance to puddle on the deck..
