??? about fiberglass roofing a houseboat
I have a houseboat whose roof has a bunch of thin
spider cracks, as well as some a bit bigger. The biggest ones aren't wide enough to get any more than a razor knife blade in, if that. I want to put some more fiberglass sheet on it, and have never done that before. Having talked to several people about it, the following is pretty much the impression I've developed about doing the job, and I'd appreciate any more suggestions or advice people are willing to sha · First, use something like a thin wheel on a grinder and dig out the larger cracks, then fill them in with rosin to make them strong...if that's not done before sanding, the cracks will fill up with dust and never get strength from rosin entering them. · Sand the area with medium grit sandpaper. · Clean area with acetone. · Cut fiberglass cloth to fit the area, then staple in place. · Saturate the cloth with rosin using a roller. Best to set up a cover like a tarp, because in direct sun the rosin could set up too quick. · After all that has been done and dries, apply gel coat ...I've heard to apply 1, 2 and 3 coats, so as yet don't have a good idea of how many to apply. One of the things I'm still trying to figure out, is how to deal with the excess rosin which will want to drip down the side of the boat. Can anyone suggest any good way(s) of dealing with that issue? |
