Chlorinated Rubber antifoul

[Ifraser]

I recently attended a wooden boat meet in Poole harbour where I discovered one of the boats was using Chlorinated Rubber paint under the waterline. apparently it has antifoul properties but more importantly it effectively coats the bottom of the boat in rubber. You may have seen my earlier posts that I have an edge glued carvel boat with some leaks. Could this paint system assist?? Anyone know or heard anything about it....thanks Iain

I hate to sound depressing, but I think you will find that most antifoulings use chlorinated rubber as the binder. If it uses "Thinners no 3" it is chlorinated rubber. A fairly cheap and durable paint, if a gloss finish is not needed, but alas no caulking properties to speak of.

Years ago there were sundry magic rubber based brews such as Black Rubber Sheathing and Limpetite, which did stop some leaks and apparently stopped worms as well, but they are long gone from the market.

Its really a tie coat, intended to allow antifouling to be applied over other paint systems such as epoxy. I use it because also it's said to have some anti-corrosion properties. Can't see it helping much with leaks, I'd look to a bituminous paint for that.

Where chlorinated rubber paint scores is in its flexibility; very useful when you sail an expanding, contracting, wracking classic.
