Gluvit And Cloth

[cc190cc]

Greetings,

I am working on my aluminum boat renovation project and had a question about gluvit. I am repairing an area with some holes on the edge of a 90 degree angle on my lower hull. After repairing the holes with marine tex, i was thinking i would gluvit over the repair area. Considering this is on a corner, 90 degree, i was hoping to build up a little extra strength and was thinking about putting some fiberglass cloth over the ninety degree area, the same way you would if i were using fiberglass.

It is kind of hard to explain so, hope you understand. I guess to make it simple, can i use a fiberglass cloth with gluvit?

Ayuh,... Donno,... But, laying cloth on a 90? corner is about Impossible....

LOL ok.....cloth is very flexible...anyone else have input?

That would probably work but structurally I would not put a lot of faith in it.

I would put down a regular layer of gluvit, let it cure for a while depending on ambient temp and then put the cloth/gluvit on in a second layer.

My gluvit took 4 days at 70 degrees to cure to the point it was not tacky or stinky.

Re: Gluvit And Cloth

You're asking if you can cover fiberglass cloth with gluvit instead of resin?

Sure, but it won't do anything. It'll be only as strong as using gluvit alone. Fiberglass resin has to hold individual fibers in position relative to each other, and gluvit doesn't do that. Depending on the coating on the fiberglass you use it may not adhere to the glass at all.

If you want to repair the holes better than marine-tex, you need to weld or patch.... the downside of aluminum boats is that they're harder to repair than fiberglass boats.

Gluv-it is just a somewhat flexible epoxy, so yes you can use it with cloth. Wrapping it around a 90* corner is the tough part, it needs to have a radius or it will lift off the surface.

I can't say it will be a long term patch, but it will hold for a while.

Re: Gluvit And Cloth

after the marine tex i would try to get some alum and bend it as needed,clean both with acetone and use 5200 and then closed end rivets

I agree 100% with jspano...why repair it like it's a 'glass rig, it's aluminum You are on the right track using the gluvit.

Aluminum is strong and lightweight, and will last a long time unless you run the boat onto some rocks, hit a submerged mine leftover from WWII, etc.

Rivets are easy to deal with and will not leak if properly used as mentioned above. I'd rivet in some bracing/supports and then apply two light coats of gluvit, allowing a week between coats.

Re: Gluvit And Cloth

I was actually thinking the patch with 5200 and rivets would be best. I just dont know what type of rivets i should use that wont lossen up. Do i just use a standard aluminum rivet i can get at hardware store?? If someone could post a link with the correct rivets to get, i will go this route.

A four foot section of aluminum i have would be perfect for it, it was just the drilling additional holes through hull below water line, and not knowing the proper rivets to use that was stopping me.

This is on the side of the hull, if riveted with 5200 it wont eventually loosen up or leak?

Would pics help?

Re: Gluvit And Cloth

I just looked up closed end rivets, looks like the standard rivet i am accustomed to. Ill go this route, im just gonna have to get some aluminum rivets that are large enough!!

Re: Gluvit And Cloth

google closed rivets
i bought mine at
WWW.RIVETSINSTOCK.COM
things you want are all alum, rivet,mandrel all parts
the one you listed is steel mandrel(that's the that looks like a nail)
don't want dissembler metal
next is the grip range... figure the gauge of the metals 2 pc 3/16 = 6/16= 3/8

Re: Gluvit And Cloth

remember a 16th of an inch = .0625
3/16= .1875
3/8 =.375
for the grip
if i have this right if the 2 pcs of metal are 3/16 each which =.375 you would need the grip range in or just above that

Re: Gluvit And Cloth

Thanks alot Joe!! One more thing, i have the boat completely gutted right now. Should i put the patch ont he inside, outside, or both?

Re: Gluvit And Cloth

i did mine on the inside thought the surface was cleaner,no paint and would be less drag on the hull.
look at my thread(it's in my signature) the last page

mine was on a flat surface

chad

thanks
just read all labels and prep like what was mentioned above

Good Luck

Re: Gluvit And Cloth

IF the hull is stripped....... consider having the holes welded up.

Do not weld seams that are riveted but, by all means consider welding for a hole and follow it up with gluvit.

Be cautioned that jspano has done some great work so he set the bar at a good height for a good repair
