Gorilla 2 Part Epoxy
Two-component epoxies are probably the strongest commercially available adhesives. They are used for robust projects and repairs where maximum structural strength is needed. They do a phenomenal job at bonding stones, and this gorilla 2 part epoxy is the best one we found!
This Gorilla epoxy is the preferred model for bonding stone because of its clear drying color. Most of the epoxies leave an ugly dark or discolored residue when they dry. The Gorilla 2-part epoxy dries crystal clear, leaving you with a clean and professional-looking finish.
The application and preparation of this epoxy are much easier than with other models. This epoxy has a syringe system that allows you to mix an equal amount of the resin and the hardener.
This system is great if you don’t have experience with mixing 2-part epoxies or just want an easy mixing experience where you don’t have to think about the right amount of the two components. You also get a cap that you can place on the nozzles to prevent the hardening of the adhesive in the bottle.

Overall, this gorilla 2-part epoxy is an excellent choice for heavy-duty stone repairs and projects. Its extreme tensile strength will ensure your bonds are strong and enduring.
Gorilla Original Waterproof Polyurethane Glue
Here is another gorilla glue on our list. This time, it’s the original gorilla polyurethane glue that bonds stones superbly.
The original gorilla glue has the power necessary to bond even the heaviest and most robust stones. Only a small amount of glue is needed since the glue expands as it dries. This foaming makes the bond extremely strong and will hold the rock pieces firmly.
The environmental resistance of this adhesive is as good as it gets. Water, snow, sun, or wind, nothing can disturb the bonds. This glue will withstand all conditions and is ideal for outdoor use. If you have to repair a broken statue or stone masonry, this is the glue to go for. It will hold that bond for ages!
The gorilla polyurethane glue works excellent for a stone to wood gluing combination. This type of adhesive is designed for bonding porous surfaces, and gorilla specializes in wood adhesives. This makes this adhesive the best glue for stone to wood you can buy!
There are many other materials this polyurethane glue can bond, such as metal, glass, plastic, and more. While it works with non-porous materials well, it performs the best on porous surfaces.
One thing we don’t like about this glue is the drying color. It has a brownish color when dry and doesn’t look so good when the bonds are visible. If you’re concerned about the looks of your stone project, painting the dried residue is a great solution.
This adhesive is very affordable, and when you factor in the strength and the spectacular environmental resistance, this is a steal of a deal!
J-B Weld 8265S Original Cold-Weld Steel Reinforced Epoxy
The J-B Weld Steel Reinforced Epoxy is officially our strongest adhesive on the best glue for stone list. It has an unmatched bonding strength and is suitable for stone projects where maximum structural resistance is necessary.
The environmental resistance of this glue is surprisingly high for an epoxy adhesive. It can withstand temperatures of up to a whopping 550 degrees. That kind of resistance is on par with most polyurethane adhesives. This epoxy also offers good water, petroleum, and chemical resistance.
The unmatched strength we mentioned earlier is what makes this epoxy stand out. It has an incredible tensile strength of 5020 PSI! That means that it can withstand over 2 tons of pressure per square inch, which is a weight of an SUV! This amazing strength makes this glue a perfect choice for bonding large and heavy stone parts!
This type of strength is achieved by metal reinforcement. It also provides great metal and stone bonding properties. This makes it a phenomenal choice for gluing stone to metal! Apart from metal, it can also bond stone with plastic, wood, ceramic, and more.
This adhesive seems almost too good to be true because of its extreme strength, resistance, and versatility, but it’s not all sunshine and roses.
The J-B Weld Epoxy takes 4-6 hours to set and requires clamping. That’s a really long setting time, and if you’re not repaired to wait for that long, a quick setting epoxy like the one from Bob Smith Industries is a better choice.
One more drawback of this epoxy is that it dries dark grey. It is not suitable for visible bonds but can be painted if needed. Look for a clear drying epoxy like the one from Bob Smith Industries we also previously mentioned.
While it takes a lot of time to dry and doesn’t provide the best-looking bonds, this epoxy definitely has its applications. It’s irreplaceable when it comes to stone structures that require massive strength.
Bob Smith Industries BSI-201 Quick-Cure Epoxy
The last glue for stone on our list is the quick-drying epoxy from Bob Smith Industries. It is an epoxy that gives you both quick drying time and clear drying color.
Bob Smith Industries manufacture some of the fastest setting adhesives on the market. They didn’t like that epoxies usually need so much time to dry, and that’s why they made this epoxy that sets in only 15 minutes!
It’s by far the fastest drying epoxy for stones we found and if you don’t need much time for repositioning the stone parts, this will save you a lot of time!
Another perk of using this epoxy is that it’s clear drying. This is not common with epoxies as they tend to dry in color and leave an ugly-looking residue behind. Using this epoxy, your stone projects and repairs will look like they’ve been done by a professional!
This epoxy works great on stone because of its flexibility that doesn’t make the bond brittle over time. This gives you a resistant bond that will last for years!
The one thing we don’t like about this epoxy is the limited water resistance. It is not suited for outdoor applications and highly moist environments. It’s best to use it for indoor stone projects.
The strength of this adhesive is solid but isn’t on par with the highest performing epoxy models. The J-B weld steel-reinforced model is almost as twice as strong as this epoxy. This means that this glue is best suited for medium-strength projects that require clean bonds and fast results.
What To Look For When Choosing Glue For Stone
Stone is a unique material that has its unique features. Because of that, not every adhesive will work with it. We will go through the most important factors to consider when choosing glue for stone. Before we do that, let’s find out a bit more about stone.
Stone is a term used to describe a piece of rock. This word is often used to describe a natural rock that is frequently used as a building material. Those can be granite, limestone, and marble.
The most important thing to remember about stone is that it is a porous material. That means that it has holes where liquid can pass through.
Certain adhesives work better for porous materials like stone, and those are the ones we’ve recommended and the ones we will discuss now.
Type Of Adhesive
The main three adhesives that bond stones well are polyurethane adhesives, epoxies, and super glue. Other adhesives can work but are not as effective as these three. We will now go through each of these and examine their pros and cons.
Polyurethane Glue
Polyurethane adhesives are urethane-based glue that has exceptional heat and water resistance. It is one of the best adhesives for bonding stones, especially if the stone is located outdoors.
Polyurethane adhesives are used for heavy-duty construction applications and are up to 5 times stronger and resistant than basic construction adhesives. They usually expand when it dries and bonds the stone really well because of that.
It offers great flexibility, and its bonds last the longest on stones because of that. If applied correctly, you can expect these bonds to last for decades!
Their extreme resistance to environmental conditions further improves the longevity of the bonds. These adhesives can withstand extreme temperatures with ease. You can even apply them in sub-zero temperatures, and they will cure without any problems.
They offer superb water resistance and will withstand excessive rain with no issues. They are the most resistant adhesives you can find.
The drying time of these adhesives averages 30 to 60 minutes. They need a full day to cure and often require clamping.
These adhesives don’t dry clear, and since they expand, they can sometimes ruin the looks of your stone. For stone projects with visible joints, clear drying adhesives like super glue and some epoxies are preferred.
Polyurethane Adhesives For Bonding Stone
Pros:
- Extreme environmental resistance
- One of the strongest commercially available adhesives
- Their Flexibility doesn’t make them brittle, which improves durability
- Perfect for outdoor stone projects and repairs
Cons:
- Isn’t preferable for visible joints as it expands and doesn’t dry clear
Epoxy Adhesives
Epoxies are the strongest adhesives that you can buy. They offer extreme structural strength and usually have solid water and heat-resisting properties.
The main advantage of using epoxies is their massive strength. There are epoxies with a tensile strength that exceeds 5000 pounds per square inch. That means that this glue can withstand a pressure of one compact truck per square inch!
That’s an unmatched type of strength and makes this glue sufficient for even the most heavy-duty stone projects and repairs.
These adhesives usually have solid water-resistance properties. They aren’t as good in resisting moisture as polyurethanes but are sufficient for most normal conditions with moderate rain and moisture.
Epoxies aren’t that great in sub-zero temperatures but usually perform excellently in hot environments. Most of the time, they can resist temperatures of up to around 200 Fahrenheit and sometimes more!
The drying time for epoxies varies a lot. Some models set in as much as 10 minutes, while there are epoxies that need up to 6 hours to set.
One thing that deters people from using epoxies is the difficult application. You will need to mix precisely the same amount of hardener and resin to ensure good adhesion.
After that, the bonded parts require clamping, for which you will need equipment and some previous experience as well.
This glue is available in clear drying color and can give you a pretty clean-looking bond.
Epoxy Adhesives For Bonding Stone
Pros:
- Massive amount of tensile strength
- Usually clear drying
- A lot of different setting time options for anyone’s preference
- Great for heavy-duty stone bonding projects and repairs
Cons:
- Not easy to work with for beginners
Super Glue
Cyanoacrylate adhesives or super glues work pretty well for bonding stones. They are quick-drying and offer enough strength to bond most small stones.
Super glue is best for small stones and projects where quick drying time is essential. This glue is ideal for homemade jewelry and crafting projects containing stones.
It is also excellent for projects where many different materials are to be bonded with stones. You can bond plastic, wood, glass, metal, leather, and almost anything you can imagine to stones with this adhesive.
The drying time of this glue is lightning-fast, sometimes as quick as 15 seconds! When you don’t need to reposition stones too much, you can benefit significantly from this glue. It will speed up your projects exponentially!
The bonding power of these adhesives is solid but super glue isn’t as strong as polyurethane adhesives and not even near the epoxies. That’s why it’s best for crafting and DIY jewelry.
The water-resisting properties of this glue will make your jewelry easily washable, and the solid heat resistance makes it dryer-safe.
Super Glue For Bonding Stone
Pros:
- Super fast drying time
- Very versatile
- Affordable
- Great for small stone projects and crafts
Cons:
- Not as strong as polyurethanes and epoxies
Viscosity
The viscosity of the adhesive for stones is one of the most important features to look at.
The recommended viscosity for gluing most types of stone is medium or gel-like viscosity. This is the consistency such as that of a gel super glue models.
If an adhesive is high in viscosity, it will have a hard time seeping through the stone and making a good bond.
On the other hand, if an adhesive is too liquid, it might seep too much, again weakening the bond.
The syrup-like consistency of medium viscosity adhesives seeps just enough through the stone and gives you a durable and solid bond.
Medium viscosity glue is also easiest to apply and is a bonus and a reason more to go for this type of glue.
Drying
The drying time and color are very important factors to consider when choosing glue for stones.
For the fastest drying time, super glue is the best choice. If you actually need more time for assembly of the parts, going for polyurethane or slow-setting epoxy adhesive is a better choice.
Both epoxies and super glues have clear drying models, and both can provide clean-looking bonds that won’t ruin the stone’s looks.
Polyurethane adhesives don’t have that many clear-drying models, at least not ones that we felt comfortable recommending. If you’re concerned about aesthetics, look elsewhere.
Tips For Gluing Stone
- Before starting to glue, make sure to sand the stones that you want to glue together. After sanding, clean them thoroughly.
- When working with industrial-strength adhesives like epoxies and polyurethane glue, make sure to wear protective equipment. Wear old clothes and gloves as these adhesives are almost impossible to get off when they cure.
- Makes sure to work in a well-ventilated area as all of the adhesives we recommended contain fumes that can cause headaches or nausea.
- When working with adhesives, especially more complicated ones like epoxies, read the manufacturer’s instructions for your safety and ensure the best possible adhesion.
- Leave the stones undisturbed for 24 hours, no matter what kind of adhesive you are using. This way, you will ensure the longevity of the bond.
Conclusion
That about covers it for everything you need to know about glue for stone.
Polyurethanes work best for outdoor projects, epoxies for the projects where the highest structural strength is needed, and super glue for quick and easy crafting and jewelry DIY projects.
Any of the models we reviewed work great with stone, and you can’t go wrong with any of them!
