| Post subject: | Delam repair on side of H 18- |
I have done deck repairs before, but this one's a bit different. Estimating 1980 vintage hull. An area approximately 3' long by 1' high is soft, directly outboard of the daggerboard slot. From inside there is a layer of fabric hanging like a curtain, not glued to the fiberglass wall (!) No stiffness in the delammed fabric. Hull is relatively stiff outside, but not comparable to original or rest of hull. I was thinking of injecting epoxy through the fabric and rolling it in to saturate. Hull can be positioned on its side so epoxy will flow flat out over the repair rather than drip down while drying. I suspect someone mighty say, no you need to cut it all out and add saturated fiberglass cloth layers... which I'd rather not do. Any one else have experience to share? ? |

I've done a bit of fiberglass work, building a boat. Your idea seems reasonable to me. Maybe add another layer of epoxied cloth over the repaired area and extending a foot or so either way to further stiffen it. |

Your idea sounds good. What I would do after you (carefully) drill some holes through the inner skin, roll the hull on it’s side, and inject the epoxy - place some bags filled with sand on the inside skin of the hull. This will put even pressure on the skin to hold it in contact with the core. Make sure the outside of the hull is also supported so it doesn’t deform under the weight and take a permenant set. You will probably also want to put some release film or waxed paper between the bags and the inside of the hull so they don’t get stuck to the epoxy. sm |
