Make Your Super Glue Cure Faster Than Ever With One Simple Addition

Delivering a strong and long-lasting hold for common materials such as plastic, glass, and wood, super glue (cyanoacrylate) has been a favorite adhesive since 1942. Super glue dries quickly, i.e. shifts from a liquid to a solid, but curing is what creates the firm full-strength bond. After application, the glue reacts to the moisture in the air or on the materials' surface, hardening during the process. The overall glue curing time varies by the brand, temperature, and humidity levels present when you apply it. If you don't wait until it's cured to its full strength, the adhesive might not withstand the stress or force of handling. But what if you want the glue to cure faster? The simple addition of an activator spray adds moisture and acts as an accelerator in the curing process, creating the bond almost instantly. The activator spray, typically available from hardware stores, is often applied to the substrates' surface before adding super glue.

Cyanoacrylates, sold both in liquid or gel form, are adhesives with home, crafting, and industrial applications. They require and react with moisture in a heated process known as polymerization. During polymerization, the glue's molecules combine, forming a polymer network. This process is what activates the super glue's bond, letting it adhere firmly to the application surface. Working as a catalyst, activator spray speeds up the required time for the super glue's polymerization.

You can use this genius super glue trick anytime you want faster cured glue, or when in a challenging environment. For instance, on cold, dry days or in low humidity conditions, the activator is a good supplement to kickstart curing. It also helps counteract other influencing factors such as light, temperature, and adhesive thickness, which may slow down the cure. Working with porous materials like wood or fabrics can be difficult if the glue penetrates the surface's pores too much. Activator spray is a good guard against this process, letting it cure before absorption occurs. It's also a proven gap filler when mending or bonding items with significant gaps, such as cracks.

Not using an activator spray is a common mistake made with super glue. If you've never used it before, look for top-rated options such as AG Adhesive Guru Glue Accelerator Spray or Magic Chems CA Glue Accelerator Spray. Some companies also sell super glue and accelerant packaged together. The precise directions may vary by activator brand; however, you typically spray a light coating on the substrates' clean, dry surface. You will then apply the super glue on the opposite side of the substrate you want to repair. Finally, you can then hold the two items together to create the instant bond. Activator spray is highly flammable, and must be kept away from open flames or heat sources. Only use it in a well-ventilated space, and avoid breathing the spray's fumes. Following all manufacturer's instructions, wear protective gear when applying. When not in use, always keep out of reach of children and pets.
