I just finished fixing a fracture on the rail. The resin has hardened and I can see the texture of the glass and the fibers on the edges of the glass did not stick to the board, what did I do wrong? Also, when I was applying the resin to the cloth, the cloth was moving with my stroke, is this ordinary? I’m guessing I didn’t sand the ding enough to begin with. Should I go back and fix this or am I fine?
pix will always help you get a better determination of the best course of action…but from the sound of things, you probably just didn’t sand around it enough to get a good bond. as long as it’s smooth, even, and water tight…i wouldn’t worry too much about it. if it was a really poor repair, then it probably won’t last. fix it now…fix it later (if it needs it)…your call.
If its your board, abd the repair is smooth and water tight go surf if it starts to go after 1 or 2 setions repair it again.
If on the other hand it is someone else’s board, don’t leave it to chance re-do it now.
Lets see - if I understand it right, you have some frayed edges sticking up around the perimeter of your cloth patch and the cloth in general is only saturated to where the weave of the cloth itself is apparent and kinda rough ( though the cloth itself is wetted out all the way ) , right? Cos you either squeegeed your repair patch or brushed in resin pretty stiff-like?
Good. That’s the way it should be. No excess resin, nice strong lamination. The frayed edges are a bother, true. But you were gonna need to sand there anyhow.
Sand the edges to a feather edge, hotcoat/gloss it to fill the weave and you’re there. Next time, you might tape the cloth down on all sides with masking tape around the edges, making sure it’s stretched out flat, if the cloth moving about worries you, but as long as your patch is flat, completely wetted out ( no dry spots ) and pretty much centered on the ding with a reasonable amount of overlap onto sound glass all around, you’re fine.
When I’m in a rush I’ll try to do an all-in-one layup, lay the resin on heavy and then try to get away with just feathering out the edges but it’s not the best way to go about it. Better off with a thin lamination that covers the ding and shows you any low spots, high spots and such that you’ll have to deal with .
hope that’s of use
doc…
