Boy I messed this up! I was putting on the epoxy, using a MAS 2:1 epoxy. After I was finished and I was marveling at the job, I noticed that there were a few spots that were missed. I had very little epoxy left so when I poured it out there was not enough to align with a mark on the graduated plastic cups I was using, so I eyeballed the ratio. Bottom line, the ratio was bad and now wherever I put this last bit of expoxy is soft 4 days later. Areas where I did not hit with this mis-ratio’d batch is OK.
I am planning to build my first S&G plywood kayak. I am looking for an advice on Epoxy. What kind of Epoxy will I need and how much quality do I need to buy?
Preparing to re-epoxy after some repair work. Since my initial build, I have been watching Nick Schade videos. Interested in his method to avoid epoxy bubbles. Have seen him use both a torch and heat gun. What is better? Research says heat gun can blow the epoxy around but is more controllable then a propane torch.
While I've built 5 S&G boats, I know very little about how to varnish them; I just blindly did as I was told. That's no longer satisfactory. Lately I've been reading forums, etc, about the subject but I still have a couple unresolved questions. And I think the answers would be of interest to other builders.
I'm now in a point where final sanding is more or less done and in some places I have reached glass fibers too (edges of overlaps and reinforcement patches). Should I seal these areas with epoxy before applying varnish? I'm worried, that the glass matrix will be visible under the varnish unless it isn't surrounded with epoxy. This is my first boat to build and the finish will be far from perfect anyway. So if the effect is minuscule, then it won't really matter. I'm using a natural oil based boat varnish (Le Tonkinois).
I completed a Guillemot Petrel late last fall so it never saw water, stored indoors all winter. I got it out this spring and something had happened to the finish. I am assuming I made a BIG mistake as I have built several kayaks and this is the first finish problem I have had. I thought I followed the same procedure as on previous boats but apparently not . . . .
A couple weeks ago I took time out from other projects to do some quick maintenance on a few a my kayaks. I had a broken back band, worn out gasket and a big ding to deal with. The video is below.
Probably of most interest to people is dealing with the beat up bottom of my Petrel Play SG. This boat has a single layer of glass on the bottom, doubled up only on the keel line. I take this boat to play in rock gardens where the surge sometimes drops me hard on pointy rocks.
i had a disheartening situation tonight. I’m putting thin strips of bent wood on the inside lips of my deck hatches to seal against the foam on the underside of the hatches. I hot glued blocks onto the deck for clamp blocks. Long story short, I knocked off one of the blocks and a chunk of epoxy went with it revealing the fiberglass below. I’ve searched the old archives briefly and didn’t find anything similar. Does anyone have any advice on how to make the least obvious repair? I can’t sand any without getting into the glass.
