graphite/epoxy over varnished finish

 

I have a WD10 with a varnished hull. I am sanding off the varnish and will replace it with the graphite/epoxy mix. Now that I have sanded, the hull is completely gray, with splotches of darker gray where the wood grain does not show through quite as much.

How much do I need to sand to apply the graphite/epoxy mix?

Do I have to remove all the varnish (and how would I know that), or is the sanding just needed to create a suitable surface for the graphite/epoxy to adhere well?

 

Thanks, Jerry

Hey Jerry,

You need to sand the same as if you were applying a new coat of epoxy. Just a light sanding will do, no rougher than #220 for sure.

You need to remove all the varnish and leave a rough enough surface for the new epoxy to stick.

Have fun,

Laszlo

Thanks Laszlo. It worked great. No more worrying about going over beaver dams!
