The best types of glues for building a spaghetti bridge are:
- Hot Glue
- Cyanoacrylate (Super Glue/Gorilla Glue)
Due to convenience, cyanoacrylate glues, like super glue or gorilla glue, are the best for spaghetti bridges because they are easy to use, fast-drying, and incredibly strong. However, if you have them on hand and don’t mind the potential mess, epoxy or hot glue are better.
The type of glue you choose will either make your spaghetti bridge stronger or cause it to fall to ruins. It would be best to have a strong adhesive that will rise to the challenge. See below for the different types of glue you can use for your spaghetti bridge.
One of the most substantial types of glue is epoxy. Epoxy is a strong resin that stands up to the competition. Those who have built spaghetti structures in the past state this is one of the best adhesives for securing your formation.
Epoxy kits vary in price, but this brand found on Amazon is a low-cost option. This epoxy dries clear, is non-toxic, and is easy to use. You can apply the epoxy with the applicator included in the package or use a clean paintbrush to apply a thin coating.
Mixing epoxy can be messy. However, here is another option that is a highly-rated craft epoxy that does not require mixing. The easy school glue cap allows you to apply the adhesive with minimal mess easily.
It is important to note that epoxy does take several hours to dry. You can speed up the drying process by incorporating heat, such as using a hairdryer or a space heater or increasing the room’s temperature.
Veteran spaghetti architects recommend coating the entire structure in epoxy once you’ve erected your bridge. This coating fortifies your framework for added stability.

2. Hot Glue
Hot glue is an excellent option for spaghetti and other pasta structures. The glue is polymer-based and solidifies at room temperature. You may be concerned that the heat will cause the spaghetti to warp. Since hot glue is polymer-based, it will not interfere with the structural integrity of the noodle.
In this YouTube video, you can see how fast hot glue dries on pasta compared to regular white school glue:
The host shows that with the hot glue, noodles dry in place without being supported for a lengthy amount of time. Conversely, the white school glue requires several seconds to a minute of support before the glue securely dries in place. You can see how the structure wobbles and falls over in the school-glue example, whereas the design of the hot glue model remains intact.
Hot glue is more pliable than other types of adhesives, which makes it an excellent option for the joints and corners of your spaghetti bridge. You can continue adjusting your bridge as it dries without sacrificing stability. You can also use hot glue to create a sturdy spaghetti base for your structure.
3. Cyanoacrylate (Super Glue/Gorilla Glue)
Super glue is tried and true, suitable for everything adhesive. This old, reliable adhesive is commonly found in all craft stores. Cyanoacrylate glues are fast drying, durable, and used on almost any surface or material. This makes them incredibly favorable for spaghetti structures.
Super glues come in thin, medium, and thick viscosity. The adhesive quality of the bond increases with the thickness. A thicker consistency is a heavier and stronger mixture, while a thin viscosity is lighter but less robust than the thick version. For best results, you can use thick glue for the base and thin glue for the top of the bridge.
Gorilla Glue Super Gel is a favorite among spaghetti bridge engineers due to its rapid drying time and durability. This product provides an easy, easy-to-use applicator and dries in under one minute.
It is not advisable to mix different glues in one solution because glues often contain toxic chemicals, and you never know how these chemicals will react with others. However, you can incorporate each of these adhesives into other areas of your bridge.
As mentioned previously, epoxy is a fan favorite and provides excellent glue for the base. Hot glue is ideal for the corners and joints of your bridge. Gorilla Glue may be beneficial to you for touch-ups and final details because of its sheer strength– even in small quantities.
Choosing the correct type of glue for your project is essential. You want to be sure the glue is strong enough to hold your bridge upright and gentle enough not to damage the spaghetti.
Also, these glues vary with drying time – epoxy may take hours, hot glue takes minutes, and cyanoacrylate is usually instant. Continue to support your bridge during the drying time, and you will have a successfully sturdy build.
