Gorilla 7700111 Super Glue Gel


Gorilla Super Glue Gel, 20 gram (Pack of 2)

Gorilla glue is known to bond everything, and those bonds are known to be rock solid and durable. That’s why the gorilla super glue gel is one of the best choices for joining metal to stone.

The standard liquid gorilla super glue can do the trick as well, but we had more success with bonding stone to the metal with the gel version of this glue because of its viscosity.

The liquid formula is too liquid for this application. It runs, spills, and makes a mess out of your project. On the other hand, this gel formula makes the application of the adhesive a breeze! The glue goes right where you want it to and doesn’t set as fast as the liquid version, giving you more open work time with the glue!

The structural strength of this adhesive is superb. It will bond stone to meta amazingly and really fast as well! This is the advantage of this super glue compared to others. It cures in only 60 seconds, which means you can finish your project sooner than with the other adhesives!

This particular model of gorilla glue doesn’t have the clogging problem of some of the other gorilla adhesives. The specially designed anti-clog cap ensures your glues durability and makes you use every single drop without any waste!

The Gorilla glue gel is an ideal choice for gluing stone to metal. The bonds are strong, drying is fast, and the application is as easy as pie.

This is another very strong cyanoacrylate glue or superglue on our list that bonds stone to metal with ease. It’s got excellent structural strength and holds the bond much better than regular CA glues.

The trick is the special formulation of this adhesive that makes it up to 3 times stronger than “normal” super glues. It also makes the viscosity much higher and therefore makes application a breeze. You will glue metal to stone in just a few seconds with this phenomenal glue!

The thickness of this glue is medium, and that makes it so easy to work with. No spillage, no mess, just a beautiful-looking bond that’s clean and strong. Another thing that enhances the looks of the bonds with this glue is the fact that it dries clear. It doesn’t leave any ugly residue when dried and is transparently clear.

We absolutely love the quick curing property of this glue. It makes you finish any project or repair so much faster. This CA adhesive takes only 5 to 15 seconds to cure! That’s extremely fast! It doesn’t require clamping as well and makes the whole gluing process a care-free experience.

Bob Smith Industries BSI-201 Quik-Cure Epoxy (4.5 oz. Combined),Clear

Here is another Bob Smith adhesive that cures ultra fast. This company is known to produce excellent adhesives that have unbelievable curing times, and this epoxy is no different.

After mixing the hardener and the resin, you will have a 5 minute open work time with the epoxy. After that, wait for another 5 minutes, and voila! Your stone will be attached to the metal, and the bond will achieve its full strength in only 1 hour!

That’s probably the fastest curing time we saw on a 2 component epoxy, and that alone makes it a worthwhile purchase!

Apart from its crazy fast curing times, this epoxy forms pretty serious bonds. The stone and the metal will be bonded with no problem, and what’s more important, they will remain joined for a long, long time.

This epoxy has tremendous extreme temperature resistance. It will withstand temperatures ranging from -40 to 180 Fahrenheit! To add to its environmental resistance, it’s also waterproof, making it resist high moisture conditions.

We love how versatile this epoxy is! If you end up with some leftovers from your metal and stone project, you can easily use this glue to bond glass, ceramics, laminate, and more!

One unique feature of this epoxy is its clear drying color. Usually, most epoxies have a gray or black color when they dry, but with this epoxy, the results will be much cleaner and better-looking. It’s excellent for visible joints that need to be transparent for the look not to be altered.

All in all, this epoxy will do a fantastic job of attaching stone to metal. It makes bonds of professional-grade that look good and last long.

Glue For Stone To Metal – Guide


In this section of the article, we will share with you some of the things to look for when choosing glue for stone to metal.

Type of Glue

3 adhesives

The type of glue you use for bonding metal to stone is crucial. You won’t achieve the same bond strength, longevity, and resistance with different types of glue.

The ones we recommend using are epoxies (single and two-component), cyanoacrylate or superglues, and polyurethane adhesives. PVA glues don’t work that well with stone and metal and should be avoided.

Epoxies

Let’s start with epoxies. They are an excellent choice for bonding stone and metal. They have everything you need, strength, durability, clean and professional-looking results.

Epoxies are known as one of the strongest commercially available adhesives with a tensile strength of 5000 PSI+. That’s some serious structural strength that will be more than sufficient for bonding metal to stone projects in any environmental conditions.

It’s also waterproof and has great moisture resistance. The hot and cold air doesn’t affect the bond as well.

One thing worth mentioning is that the epoxies aren’t so easy to apply like other adhesives. This is especially true for two-component epoxies that require mixing the hardener and the resin in equal and precise amounts. It takes some practice, but once you get used to epoxies, you won’t be able to stop using them.

Super Glue

Super glues are one of the most popular adhesives today. They are preferred by many because of their easy application and reliable and strong bonds.

They also work excellently on attaching metal to stone. But not every super glue will work for this application.

You need to make sure to use super glue that has more tensile strength than the regular crazy glue and similar models. Gorilla glue, Loctite, and Bob & Smith were all tested by our team, and we had excellent results with these high-grade cyanoacrylate adhesives.

The advantage of using super glue for stone and metal is the ease of use. You need to apply the glue, wait for a minute, and that’s it! It’s a great choice for inexperienced people with no prior practice with adhesives.

Polyurethane Adhesives

Polyurethanes are up to 3 times stronger than regular construction adhesives. These adhesives are used by professionals on heavy-duty projects that require superb resistance to environmental factors.

Because of their unmatched strength and resistance, they make a great glue for metal and stone. Especially if the joined parts are to be located in moist areas and areas with extreme temperatures.

They are fairly easy to apply compared to epoxies but have long curing times compared to CA adhesives. Clamping is usually required to ensure an adequate bond.

In the end, all three choices are good and will work on stone and metal if applied correctly.

Drying Time

The drying time will determine how fast can you finish your project and how much open work time do you have with the glue.

The setting time varies a lot between different adhesives. CA adhesives have extra short set times, and while they make you finish faster, they aren’t suited for joining parts that require more time for assembly.

Epoxies and polyurethane adhesives usually have long settling times of 5 to 30 minutes. They are good choices for delicate parts that need accurate positioning.

The curing time should always be as quick as possible. When the adhesive is fully cured, it achieves its full strength. You want this to happen as soon as possible to be able to use the bonded parts.

Super glue wins here as it has some superbly fast curing times of just 15 seconds! There are some epoxies like the one from Bob Smith that cures in 15 minutes but they usually cure in about 4 to 24 hours. Polyurethane adhesives have almost the same curing times as epoxies.

Environmental Resistance

From the three types of glue we described above, polyurethane glue has the best tolerance to temperature and liquid.

It’s specifically designed to work in harsh outdoor conditions. It tolerates water and moisture without any issues. Snow, sun, and rain can’t do anything to the bonds from this adhesive.

On the other hand, super glue isn’t nearly as good for the outdoors application as polyurethane. It has acceptable water resistance but doesn’t tolerate heat and cold that well.

Epoxies perform really well in moist environments. They will resist extreme temperatures as well. They are a solid choice for outdoor projects but are not as good as polyurethanes who should be your first choice for those types of crafts.


Frequently Asked Questions


How to attach stone to metal?

Prepare the surface of both materials by cleaning them with a solvent like acetone. Apply the preferred glue on one part and press the other onto the glued area. Leave the parts undisturbed for at least an hour. We recommend using epoxy, super glue, or polyurethane adhesive for this type of bonding.
