When you need to fix something broken, choosing the right glue is important. Two popular options are JB Weld and Gorilla Glue. Both are strong, but they work best in different situations. This article will help you understand their differences and decide which one fits your project.
What Is JB Weld?
JB Weld is a two-part epoxy glue. It comes in two tubes, a resin and a hardener. When mixed, it creates a strong, metal-like bond. This glue is famous for fixing things made of metal. It can also work on wood, plastic, and concrete.
JB Weld is often called the “World’s Strongest Bond.” It can hold metal parts together like a cold weld. People use it for car repairs, plumbing fixes, and machines that need steel strength.
Key Features Of Jb Weld
- Strong bond, especially on metal
- Can be sanded, drilled, and painted after it dries
- Resists heat up to about 550°F (288°C)
- Works on metal, wood, plastic, and more
- Takes about 4-6 hours to set and 15-24 hours to fully cure
What Is Gorilla Glue?
Gorilla Glue is a popular brand with different types of glue. The most common are:
- Original Gorilla Glue (polyurethane type)
- Gorilla Epoxy (two-part epoxy)
- Gorilla Super Glue (cyanoacrylate)
The original Gorilla Glue expands as it dries. This helps fill gaps but can be messy. Gorilla Glue works well on wood, stone, ceramics, and many other surfaces.
Key Features Of Gorilla Glue
- Expands to fill gaps
- Bonds wood, stone, metal, ceramic, foam, and more
- Waterproof and weather resistant
- Strong but not as strong as JB Weld on metal
- Gorilla Epoxy is a two-part glue similar to JB Weld
Comparison Table: JB Weld vs Gorilla Glue
| Feature | JB Weld | Gorilla Glue |
|---|---|---|
| Type | Two-part epoxy with steel reinforcement | Polyurethane, epoxy, and super glue varieties |
| Best Use | Metal repairs, high heat areas, machinery | Wood, porous surfaces, household fixes |
| Heat Resistance | Up to 550°F (288°C) | Lower heat resistance, varies by type |
| Gap Filling | Good but not expanding | Expands to fill gaps |
| Set Time | 4-6 hours | 10-30 minutes (varies) |
| Cure Time | 15-24 hours | 1-24 hours (varies by product) |
| Sandable/Drillable | Yes | No (generally) |
| Waterproof | Yes | Yes |
When Should You Use JB Weld?
Choose JB Weld when you need a very strong, metal-like bond. It works well for:
- Fixing car parts or engines
- Repairing metal pipes or plumbing
- Machine parts that need strength
- Fixing tools or metal furniture
It also works on plastic and wood but is best on metal. JB Weld can handle heat well, so it is good for hot areas.
When Should You Use Gorilla Glue?
Gorilla Glue is great for everyday fixes around the house. It works best on:
- Wood repairs like furniture or fences
- Concrete cracks or stone repairs
- Ceramics and pottery
- Plastic and foam crafts
Original Gorilla Glue expands to fill gaps. This can help if parts do not fit perfectly. But it can be messy if you use too much.
Gorilla Epoxy is good for stronger bonds and works on many materials. It is easier to use for small fixes than JB Weld.

Strength and Durability
JB Weld is stronger on metal. It can replace welding in some cases. But it needs good surface preparation. Mix the two parts well. Let it cure fully for best strength.
Gorilla Glue is strong but not as strong as JB Weld on metal. It is better for wood and porous surfaces. It is waterproof and holds up well outside.
Ease of Use
JB Weld takes more time to mix and cure. You need to follow instructions carefully. It is not very messy but requires patience.
Gorilla Glue is easier to use for quick repairs. The original glue expands, so apply carefully. Super glue dries very fast but is brittle.
Heat Resistance
JB Weld can handle heat up to 550°F. This makes it good for engines and exhausts. Gorilla Glue does not resist heat as well. It can fail in very hot conditions.
Which One Is the Strongest?
JB Weld is generally the strongest adhesive for metal repairs. It can hold heavy loads and resist heat. Gorilla Glue is strong for wood and household projects. Its strength on metal is less.
Remember, the best glue depends on your project. Use JB Weld for tough metal jobs. Use Gorilla Glue for wood and general fixes.

Summary
Both JB Weld and Gorilla Glue have their uses. Here is a quick summary:
- JB Weld: Best for metal, strong bond, heat resistant, longer cure time
- Gorilla Glue: Best for wood and porous materials, expands to fill gaps, faster set time
Choosing the right glue can save time and effort. Think about what you are fixing. Think about the materials and conditions. Then pick the glue that fits best.
Helpful Tips for Using Both Glues
- Clean surfaces well before gluing
- For JB Weld, mix equal parts thoroughly
- Clamp or hold parts together while curing
- Work in a well-ventilated area
- Follow drying and curing times carefully
- Wear gloves to avoid skin contact
With the right glue and care, your repairs will last longer. JB Weld and Gorilla Glue are both strong choices. Use them wisely for the best results.
Frequently Asked Questions
What’s Stronger, Gorilla Glue Or J-b Weld?
J-B Weld is generally stronger than Gorilla Glue, especially for metal and high-heat repairs. Gorilla Glue excels on wood and porous surfaces. Choose J-B Weld for heavy-duty, steel-reinforced bonds and durability. Use Gorilla Glue for versatile, everyday fixes on multiple materials.
Is J-b Weld The Strongest Glue?
J-B Weld is one of the strongest epoxy adhesives, especially for metal repairs. It bonds like a “cold weld. ” Its strength surpasses many glues but may not outperform specialized adhesives or welding in extreme conditions. Proper preparation and curing ensure its maximum durability.
What Should You Not Use J-b Weld On?
Avoid using J-B Weld on flexible plastics, polyethylene, polypropylene, Teflon, and surfaces exposed to extreme heat above 500°F. It also fails on wet or greasy surfaces.
What Glue Is Stronger Than Gorilla Glue?
JB Weld is generally stronger than Gorilla Glue, especially for metal and high-heat repairs. It creates a durable, steel-reinforced bond. For extreme heat or specific materials, specialized adhesives like MMA glues may outperform both. Choose JB Weld for heavy-duty, metal-focused projects requiring maximum strength.
