  • BoatUS Magazine's Mark Corke shows you how to easily fix gelcoat spider cracks, hairline cracks, and crazing in your boat's fiberglass gelcoat. While this may seem like a scary project, with a little time and patience, it's something you can do yourself with great results!
    It's important to differentiate between stress cracks and spider cracks (though the terms are often used interchangeably). Stress cracks are generally deeper, involve more than just the gelcoat, have an underlying cause (structural or impact), and are likely to come back if the underlying cause isn't addressed first. Spider cracks are less likely to come back as they're superficial and often caused by age, UV, weather, or dings.
    Here's a helpful list of the tools and products I used in the video:
    Acetone: I used an Evercoat product, linked here, but any acetone would be fine.
    www.evercoat.com/product-detai...
    Pretaped Masking Plastic: 3M brand, readily available at Home Depot. You can also find it in Sherwin Williams stores and some West Marine stores have it.
    www.homedepot.com/p/3M-Scotch...
    Dremel rotary tool:
    www.dremel.com/en_US/products...
    Dremel bit: Silicon carbide grinding bit in a bullet or cone shape
    www.dremel.com/us/en/p/84922-...
    OR tungsten carbide bit (bullet or cone), but be very careful not to grind too deep.
    Premixed gelcoat for almost any boat color:
    www.iboats.com/shop/paint-and...
    NOTE: The catalyst is included when you buy the gelcoat.
    Syringes: cheapest I've found from Walmart
    www.walmart.com/ip/Monoject-C...
    Colloidal silica: For thickening the gelcoat
    www.westmarine.com/buy/west-s...
    Plastic mixing sticks: West System
    www.westmarine.com/buy/west-s...
    Respirator: Available at home improvement stores
    Wet/dry sandpaper: (available at home improvement stores)
    www.westmarine.com/buy/3m--we...
    Polishing compound:
    www.mirka.com/Polarshine-45-P...
    Buffing machine: The one I have is no longer available but this is the equivalent
    www.dewalt.com/products/power...
    Polishing pad:

    I worked with resins, gel coats, micro bubbles (silica) and fiberglass mat in FAA aircraft mechanic school years ago. So I had an idea on how to mix gelcoat and apply. However, it’s been years since I’ve done it. This video was just what I needed to make an almost perfect repair in my transom. (Log bumped it last year and put a bunch of radial cracks as big as my hand.) I followed this video to the letter and got results I’m proud of. Best advice I could give is don’t be afraid to grind those cracks wide. I ground next to one and not directly in it as I was being gun shy. I could see the crack when I look for it, but from a few feet away it’s invisible. I figure if it opens up again next year I’ll just give it a do over. Thanks Mark for making this video and passing on all your professional knowledge!

    Great video with a wealth of information! Challenge is finding the matching grade of white for the boat. Will definitely try this !

    • @boatus
      @boatus  Год назад

      Thanks, Pierre. Yes, color matching is probably the hardest part if you don't have gelcoat that matches your boat. Thankfully several companies make premixed gelcoat to match most standard boat colors. If necessary, you can also try matching it yourself using white gelcoat and a tinting kit, though that takes a bit more finesse and practice. And some companies can create a custom match if you can bring something to match from. Good luck with your repair.

      Mark. There are two reasons for getting spider cracks (three, if you include a collision). One, is the gelcoat has been incorrectly applied too thick. Two, the laminate is too thin and flexing. Or a combination of both. Gelcoat doesn't like to flex, so the thicker it is applied the less it will flex and if there is movement in the laminate, spider cracks will appear again. Cheers

    • @boatus
      @boatus  3 года назад +1

      Thanks for the question, David. You're right -- cracks do not always happen to be in the most accessible/convenient places. However, if you are careful when filling the crack, it is usually possible to sand down the repaired gelcoat so that it is flush with its surroundings by wrapping the paper around a shaped block of wood. Alternatively, I suggest checking out another video we have done on repairing vertical surfaces where we discuss a technique that requires using a sheet of mylar - something that might work well for your situation: ruclips.net/video/5EapSjzjAyQ/видео.html

      Thanks for watching, Edward. There are two ways to get the correct color: You can buy pretinted color for nearly any boat (see the description for a link) or have it matched similar to buying paint at a store. Or you can buy tints and tint it yourself, which is a much trickier job. We are looking into doing a gelcoat tinting video sometime in the future.

    @billcook6886 3 года назад +2

    Thanks for the great series of gelcoat repair videos! Do you see any benefit to using a flexible epoxy after grinding out gelcoat stress cracks, followed by the gelcoat per your instructions? I've heard that a gelcoat-only repair may crack after a couple of years.

    • @boatus
      @boatus  3 года назад +1

      Thanks for the question, Bill. I would caution against using any sort of flexible substrate under the gelcoat. The gelcoat is essentially a stiff coating and anything underlying gelcoat that is flexible will definitely lead to cracking. Providing the gelcoat repair is done in the way that I show in the video, all will be well. The only time that I would not use my method would be when there is extensive cracking covering the entire deck, which I have seen on some boats. In this case the only sure-fire remedy is to fill and fair the cracks with an epoxy filler and then paint the surface.

    Hello Mark - Thanks for your instruction. I'm new to this process. Wondering what you can use in lieu of silica to create the paste? or would you have filled the spider crack with 3M platinum filler? If silica is the best way to go, then great; I just want to make sure I know the options. Thank you for your knowledge and instruction!

    • @boatus
      @boatus  8 месяцев назад

      Thanks for the question, Amanda. There are likely other acceptable ways to repair spider cracks in boat gelcoat, however, this is the method that Mark prefers. The silica is necessary to thicken the gelcoat enough that it fills the repair and doesn't run out. Depending on the size and location, you might be able to use mylar plastic instead. You can learn more here: ruclips.net/video/5EapSjzjAyQ/видео.htmlsi=bpGHmhU0RQEd8v5g

  • @lucianmarius2003
    @lucianmarius2003 3 года назад

    Thanks for the tutorials you posted. Please explain to me why in one case you used colloidal silica as a thickening agent for gelcoat, and in another you used only simple gelcoat. For me, the depth of the gelcoat's defects was similar.

    • @boatus
      @boatus  3 года назад +1

      That's a great question, Lucian! If you're working on a flat/horizontal surface, there's no problem using straight gelcoat for the repair. You're not fighting gravity, and it's going to stay where you put it. If, on the other hand, you are working on a vertical surface, you've got to have a way to keep the gelcoat where you put it. And it also depends on depth of the repair. If you go to our vertical gelcoat repair video (ruclips.net/video/5EapSjzjAyQ/видео.html), we had some deep holes that needed filling, which we used filler to do, essentially bringing the surface flush with the surrounding gelcoat. We just needed to brush on some gelcoat, like you would paint, to cover those repairs, and the mylar plastic gives you a smoother finish (not as much sanding required) and keeps the gelcoat from running. In the case of repairing spider cracks, you're grinding out the cracks somewhat, so there's a bit more area to fill, hence the use of the colloidal silica for thickening. Hope this helps, and thanks for watching!

    • @boatus
      @boatus  3 года назад

      Thanks for your question, Steven. Repairing the gelcoat on the bottom of the Hobie is certainly possible and you can find out more about the recommended technique for this at ruclips.net/video/TJHk81_nKRI/видео.html. To be successful, you really need to flip the boat over, which means removing the rig, but the results will be worth it. Trying to work upside down is difficult as you will be fighting gravity and working in awkward positions. Best of luck, and we would love to know how this turns out!

    • @boatus

      Hi, Steve, and thanks for the great question! You need to remove the snaps, repair the cracks as shown, and then screw the snaps back on. You should not have to fill and redrill the holes, but do put a little mastic polysulphide sealant, such as the Boatlife products available at West Marine and other retailers (www.westmarine.com/buy/boatlife--life-calk-sealant--P004_127_003_003?recordNum=2), on the threads of the screws before you reattach them.

    • @boatus
      @boatus  3 года назад +1

      Awesome questions, Mike. I'd call it about a tablespoon per syringeful of gelcoat. You can always start with a little and add more if needed until you get it to the consistency you want. (Don't forget to wear a respirator while handling the silica!) Too little, and the gelcoat will run out of the repair. Too much and it will become super thick. For nonwaxed gelcoat, you can use PVA or cover it with something like a mylar sheet. We talk about that a bit in this video, more so to keep the gelcoat from running, but it can also be used for nonwaxed gelcoat: ruclips.net/video/5EapSjzjAyQ/видео.html (You might find some other useful gelcoat repair tips depending on where the repair is and how deep.)
