    Hi Jan,

    I used this foaming agent to fill the space around the deadwood inside my keel. 

    I also used it to repair wet and damaged jefa like rudders. It doesn't expand as much as other foams, but it also generates almost no pressure so that you don't have the problem of the foam pushing parts apart.

    Edvard, it's very kind of you to share your knowledge of epoxy foam with us. Did you save any photos of the stern repair in your "Freedom 30"? If you plan to post such photos, I recommend the "attach file" function (at the bottom of the editing window).

    I've noticed that some customers of the shop you mentioned claim they get much less foam and that it should be poured in small batches. Have you had similar experiences?

    I wonder how long you've been sailing with this new stern, and if you have any way to check if the foam still doesn't absorb water?

    Best regards, Jan.

    PS  I also found another technique.

    I created this thread ("epoxy foam") as  "fork" for the   thread "Freedom 30 car ketch ...")

    …I'm intrigued by the name "epoxy foam."

     Is it the same as "two-component PU pour foam"? Or is it a different type of material?

    i found this (amongst other results) with a short web search. (i didn’t know epox foam either…)

    Thanks for the reply, Ueli! 

    I found this site too. I've been trying to familiarize myself with foam technology lately.  I'm not a chemist, but it seems to me that epoxy foam would be a very interesting product.

     Unfortunately, there's not much information on this website.  So I'm wondering if epoxy foam isn't simply two-component polyurethane foam being sold under the name epoxy foam.

    EDIT (one day later): But—maybe not? I'll continue to research the topic...

    EDIT2: link (from Edvard) to the shop in NL
