pwillems Posted July 12, 2015 Report Share Posted July 12, 2015 Hi all, Started yesterday on my Spindrift 11N. The first step involved some butt joins. All went well for one of the sheets, but it appears I failed to correctly wet out a section of the glass on one side of the other sheet. This was the first piece I laid down and the process required me to wet out the glass and lay it down before laying the ply on top of it... I can see now that I should have wet the glass out more thoroughly and also put some goop on the ply as well. The good news is that the 3 other joins look great. So, what is to process to fix this? Do I need to sand back the whole thing removing all the glass and start over?Thanks. Quote Link to comment Share on other sites More sharing options...
Dnjost Posted July 12, 2015 Report Share Posted July 12, 2015 Been there, done that. 6" angle grinder and do over. You need to apply a coat of resin to the wood prior to laying the glass as it will help wet out and make a better final bond.

pwillems Posted July 12, 2015 Author Report Share Posted July 12, 2015 All sorted. Epoxy wasn't rock hard yet so 20 mins with the orbital brought it back to bare wood. Won't make that mistake again. Cheers. Quote Link to comment Share on other sites More sharing options...
PAR Posted July 12, 2015 Report Share Posted July 12, 2015 On raw wood, you need to wetout the surface first, to prevent glue starvation. On previously epoxied wood, you just need to scuff the surface for good adhesion, unless employing another coating or lamination on "green" epoxy. It's hard to tell from your photo, but it looks like much of the joint has good wetout. Grind away the areas where it's milky, as these are the places it's not well bonded. Apply more fabric and goo to the areas you grind away. Quote Link to comment Share on other sites More sharing options...
pwillems Posted July 13, 2015 Author Report Share Posted July 13, 2015 Check this out Impressive technique. That looks like you'd barely need to sand it at all. Quote Link to comment Share on other sites More sharing options...
PAR Posted July 13, 2015 Report Share Posted July 13, 2015 Once you figure out the basic procedures for this type of joint, you can make them so they require very little effort, to fair them up. With some practice you'll stack up a handful of these joints, one atop of another, each coming out nearly perfect, once you pop them from the jig.
