Chemotherapy for Rot

 

Two very good articles on treating or preventing rot:

I am thinking that an oiled interior with an occasional treatment of ethylene glycol seems to be a great combination. The EG allays the fear of rot forming under an oiled surface.

 

I especially like how it can be applied over a painted surface (but not epoxy) and it will penetrate through to the wood.

 

Any thoughts?

Any comments?

 

Simple, cheap, and easy.  This seems like a good thing to keep in mind for wooden boats.

I am surprised this has not generated more of a discussion.

 

For the traditional builds this is an excellent way of preventing further deterioration. Basically it is applying standard automotive antifreeze with something like a pump garden sprayer to the inside of your boat. The ethylene glycol kills mold organisms and prevents further growth, and it does not stain the wood.

 

What is really interesting is that it soaks through most finishes so you can apply it over your paint and varnish. This might be something you do once or twice a year to maintain your boat.

Read those articles and they were interesting. Having been fighting mold in my boat for 2 years now I like that this stuff penetrates into the wood. That's what I could never find before.. Water and bleach did nothing but warp my plywood box tops, so I may try this stuff especially since it can be applied after. I read in the article it is preferable to find just the eg on its own, without the additional stuff they put in for automotive use. Interesting article.

I would use plain antifreeze mixed 50/50 with water to treat your boat. The only mention of the additional stuff was in the first reply, and that was for treating new plywood before encapsulating with epoxy.

That was that persons opinion, I would like to see his concerns proven by testing.  He may be making a simple thing more complicated than necessary.

 

I think Dave Carnell was referring to the old standard green antifreeze. Some of todays longer lasting antifreezes, the red ones, are made from something else.

This is of course an old post but wondering if anyone is using antifreeze on their boats. I wonder how it would work to mix it in boat soup.

CW, this discussion comes up frequently on the Woodenboatforum.com. Seems to be pluses and minuses. Take a look over there.
