Is there a way to repair this grip-textured gel coat, or whatever it is?

I have this crack. It's not structural I don't think. It's right on top of the cudy near the base of the mast. The area is still firm. Is there a way to fix this nicely?

I imagine grinding it all down for a normal fiberglass repair, but how can I get the grip-paint stuff back? Is that part of the gel coat, or some kind of paint or stick-on stuff?

An image is attached.

Thanks.

That looks like more than just a cosmetic gelcoat crack. Perhaps its flexing and some reinforcing is necessary. It might be easier after you fix that problem to just put a coat of anti-slip paint on that section as matching the gelcoat color is going to be hard,

Weedy,

I think Jim nailed it. It appears to be more than gelcoat that needs fixin'. Reinforcing from below will be the start to keep that part from flexing enough to ruin any repairs you make, so I would do that first. Then repair the topside with fillers and gelcoat, followed by nonslip. It would make good sense to pick up a copy of one of Don Casey's many books on sailboat repair. He's kind of the Bono of sailboat maintenance. One thing I think he recommends is making a mold of the non-slip from a different location so you can match the repair. Whatever you do, post pics. It's always nice to see somebody's "moistened bint" take shape. I redid my non-slip with KiwiGrip and highly recommend it. My deck is that waffle pattern and after applying KiwiGrip, it took on kind of a woven burlap (by smoother) look that I find pleasing to the eye. And it's like standing on rubber sandpaper (if that makes sense). Good stuff.

Hard to tell but looks like the cabin top where you stand to bag the Main, probably soft in that area surely wet core, worse from the crack but wet before, probably from a deck leak maybe that cleat that looks like it was added on. That spot will take on a lot of water and the rot will accelerate. I would fill with something right away if only temporary, flexible is better 5200 maybe. Or to fix correctly the easiest way is to cut a big section from the top, dry and fill as needed and set the piece back in then fix the cosmetics.

Find the leak and fix it, deck repairs are well documented throughout the forums.

Tanley, those are cool videos! I was wondering what the process would be to make a mold of the non-skid.

Tanley, good post!

As to the damage in the OP, I'm thinking someone dropped the mast or some such thing at some point. That's a wee bit more than cosmetic 'gel coat crazing'!

Hi Don, that Kiwi stuff looks pretty good.

I just went out and took a couple more pictures. One is from inside the cuddy, right under the damage, showing that the crack doesn't go through. Second is just a picture showing where on the boat the crack is, from farther away.

I also stood over the crack and bounced my 150 pound self up and down. No deflection in the crack.

if I don't get around to this repair before winter, I plan to clean it, fill it with something, and place this adhesive grip-mat stuff over it.

Tanley, thanks for the videos. I've been watching this guy on youtube too. I'm not sure it the non-skid is gel coat though. If feels rubbery compared to the gel coat.


How is this for a repair solution:

1. Scrub the thing down impeccably.

2. Sand the gel coat along the crack to see how deep it is. If it's somehow not into the glass, skip to step 5.

3. Sand/cut the cracked area away, preferably from inside the cuddy, but it's a tight fit so I might resort to working from the outside in. Sanding out for a regular structural fiberglass repair.

4. Commence a regular structural fiberglass repair, perhaps beefing-up this area from underneath. I've never done any fiberglass work before, but I've watched several videos on YouTube, and it looks like good honest fun.

5. Do a gel coat repair, maybe trying to match the grip pattern in the gel coat, if that's what it is, otherwise either leave the scar and tell myself it gives the boat character, or sand off the pattern and apply some Kiwi grip.

A bit of Marine Tex will make a good temporary repair.

Re: Is there a way to repair this grip-textured gel coat, or whatever it is?

My boat has a textured non-skid and others have had to make some repairs.

The following is what was found on the owners group for my boat.

Quote:
Repairs can be made easily to scratches and gouges in the nonskid. Wax some
of the nonskid that is OK and spray a thin layer of PVA over it. You can
make the mold with a fine grade of Bondo like material. The product we use
is Rage Gold from Evercoat. Regular Bondo is too course to pick up the
detail and last. You can make these little molds quick and easy and you only
have to make them big enough to fix the bad spot being repaired.

Prepare the chipped, scratched, or gouged spot in the nonskid by using a
needle file or scraper. Only rough up the scratch itself. Don't disturb
the nonskid next to the scratch. The mold that you made will lock in
perfectly to the nonskid anywhere on the boat. The best way to do it is to
cut a section of the mold to be just a little bit bigger than the scratch.
Spray the mold with PVA . Using a small brush paint the area around the
scratch with PVA so the gel coat won't stick to anything but the scratch it
'self. Come right up to the edge of the scratch without touching the scratch
itself. Make sure the PVA is completely dry. The hardest part of the whole
repair is making sure you have the right color of gel coat. Mix the gel coat
up and again using a small artist brush put enough gel coat in the scratch
to fill the area. Place the mold down so it locks in and put a weight on it
so it won't move. Pull the mold off when the gel coat sets up and do the
clean up. After some practice you can get so good at this that the repair
won't show at all. The explanation may be awfully wordy but it really is
easy to do. I hope this helps.
