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
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.
