Aluminum items are revered for their strength.
However, traditional tear and wear can cause them to break down, making them un-useful
But should this mean that this is the end of them? I don’t think so
I have found that with the right epoxy, any item is easily fixable.
Below I will take you through the three best epoxy for aluminum items.

1. 3M Marine Adhesive Sealant 5200 (05203)
It’s the sealant I use whenever I need to conduct some repairs on the family boat.
It has been designed to withstand water without coming loose or breaking down.
Apart from boats, you can also use it with jet skis, kayaks, and other common marine vehicles.
Key Specifications
• Compatible with wood, fiberglass, and metal
• The container comes with three fluid-ounces
• Its full curing time is 48 hours
Pros
• Highly resistant to water
• Affordable
• Flexible when dry
Cons
• It takes 48 hours to dry and up to seven days to become fully cured
• It has a strong smell
Reason for Inclusion
DIY home improvements can take on various shapes.
Every once in a while, I found myself having to make repairs on jet skis and boats and need an adhesive that can withstand water contact.
2. Epoxy Paste
If I were to give an example of the best DIY two-component epoxy, this would be it. I have used it as a coat and as a patch with equal efficiency in the past.
I particularly like it because it quickly bonds with all surfaces, except for a few plastics.
Key Specifications
• Paintable
• It weighs 3.36 ounces, and each tube has 60.0 milliliters
• Suitable for molding, filling, sealing, and bonding
Pros
• Versatile
• Very strong
• Very short dry time
• Long work time
Cons
• It results in an ugly surface (you can always paint it out)
• You need to use it immediately you have mixed it up
Reasons for Inclusion
Things are constantly breaking in the home, and when they do, I need something strong to help fix them.
I found that I can use this epoxy paste to glue (see the best glue for plexiglass here) the aluminum base of a faucet spray to an aluminum sink. How handy is that!
3. MASTERCOOL 90934 Alum Bond A/C Repair Epoxy – 2 oz.
It’s the only epoxy on this list intended to bond with aluminum.
I use it for DIY tasks involving products such as radiators, tanks, water jackets, pumps, and valves.
The two-component epoxy is specially formulated using modified curing agents to guarantee durability and maximum strength.
Key Specifications
• 650 PSI maximum line pressure
• 3500 PSI tensile strength
• 8600 PSI compression strength
• 83D hardness shore
Pros
• Easy to use
• Specifically intended for use with aluminum products
• Can be drilled, threaded, and sanded after curing
• It doesn’t take long to cure fully
Cons
• Requires a clean surface which means I can’t use it on DIY automotive repairs or improvements on greasy surfaces
• More expensive than the other epoxy for aluminum on this list
Reasons for Inclusion
It doesn’t stick up and is perfect for fixing all aluminum items, from broken ac lines to fan housings.
