Hi Patrick ,

You might take a look at this article from Practical Sailor .

http://www.practical-sailor.com/news...7sheathing.pdf

A very informative article about Dynel compared to other fabrics used to
reinforce the epoxy covering on a boat hull.

Also , go to the System Three web site and download their Epoxy Book ( caution
though , it is a 2 Megabyte Adobe .pdf file so it might take some time to down
load ) In its fifty odd pages it gives a good description of how to apply a
fiber sheathing .

An alternative would be any good book from the library about boat building with
Stitch and Glue or Wood Strip construction and then covering with epoxy and
fiber glass .


Another brand specific information page ,

Anyway , I've not used Dynel but the Practical Sailor discusses the differences
.. They seem quite similar in installation . But I think the most recommended
steps are
1/ coat the bare wood with a bit of thin epoxy - to seal the wood and keep it
from later sucking up all the epoxy meant to bond down the fiber cloth . let it
cure , full cure if the area to be covered needs the have the cloth massaged to
make it cover the area, but probably ok to proceed right away if the area is a
flat area .
2/ spread the fiber over the area to be covered , wet it out with thin coat of
epoxy , don't put on so much as to float the fiber away from the wood
3/next day start adding additional layers of epoxy to fill in the weave of the
fiber . Two or three coat probably needed .
It is probably a good idea to do this when the temperature of the wood is
dropping or constant rather that temperature rising - as temperature rises air
bubbles will tend to come out of the wood ,


But follow the epoxy brands precautions from the type of epoxy you have already
ordered about applying overcoats as to amine blush , need to wash or sand
between coats etc. they are all different .

Good Luck ,

David

I have a small carvel wooden sailing boat (20 footer .... She was Dynel
sheathed either
from new (in 1963) or soon thereafter.

I've ordered some Dynel and epoxy.

Trouble is, last time I had some good advice about applying the stuff, but I
don't recall the details (it was nearly twenty years ago) and I don't recall
where the advice came from. Specifically, I seem to remember the advice had
something to do with not allowing the cloth to "float" on top of the epoxy
but making it sit right up against the wood. I also can't remember if I
started with a pre-soaking coat into the wood and then followed up with the
cloth or whether I started with the cloth hung dry and then all the epoxy
worked through it.
