I have followed all the threads about weight vs. strength and have come up with my questions of how to find the perfect balance. I'm using 6oz. cloth inside and out and U.S. Composites slow epoxy. Please correct anything I say as wrong, this is my understanding from what I think I've read here.
When I get ready to do the saturation coat, I brush, roll, whatever, to get the epoxy spread, and then take a squeegee to remove the excess.
How long would it need to sit before the Squeegee?
Can I just push the epoxy to another part of the hull and continue on? Seems like it would waste a lot of epoxy just to squeegee it off and not use it.
Once I get ready to apply the cloth I really like the idea of doing it all at one time opposed to strips.
Do you have time though to wet out a whole hull this time of year. I'm assuming you mix a cup or two of epoxy at a time and go to work, mixing more as you need it.
Do you ever run into a problem with it kicking before you finish, or what do you do to prevent it? In my mind I can think of like your painting a wall and you keep working the wet edge.
Do you alternate back and forth from one side of the hull to the other so your always working a wet edge?
The boat I'm building has tumblehomes ( I guess that's how you'd say it) How would you do that? Pick a spot to stop putting down cloth and finish up with a strip once you flip the hull?
From my understanding you want no more epoxy than is actually needed. A thin saturation coat. Enough to wet out the cloth, then a few thin filler coats to fill in the weave of the cloth. I will say this, and it's just from making the splices. Epoxy is much thinner and easier to work with, spread and such, than poly.
This last comment is mostly for Ron. After I finished the splices tonight I had a little epoxy left over. Now I don't know exactly what time I mixed it, but I'm pretty close on when I did. After somewhere between 45mins and an hours I gave up and went in the house and it was still flowable in the cup. Question is can you work that slow. If not might think about a faster hardner
Another question just popped in my head. With epoxy do you ever back off on the hardner like you would with poly to increase working time
