The Pros and Cons of Super Glue for Household Repairs

by Ahmet Emek on June 13, 2023

When it comes to household repairs, having the right adhesive can make a significant difference. Super glue, also known as cyanoacrylate adhesive, has gained popularity as a go-to solution for fixing various items around the house. Its strong bonding capabilities and quick-drying nature make it a convenient choice for many DIY enthusiasts. However, like any other product, super glue has its pros and cons. In this article, we will explore the advantages and disadvantages of using super glue for household repairs.

What is Super Glue?

Super glue is a type of fast-acting adhesive that creates a strong bond between various materials. It is composed of cyanoacrylate, a chemical compound that polymerizes rapidly when exposed to moisture. This rapid polymerization process creates a durable and nearly-instant bond.

Advantages of Super Glue

1. Strong Bonding

One of the primary advantages of super glue is its exceptional bonding strength. It can securely join different materials, including plastic, metal, ceramics, glass, and wood. The adhesive creates a bond that is resistant to impact and vibrations, ensuring long-lasting repairs.

2. Quick-Drying

Super glue sets and dries rapidly, allowing for swift repairs. Unlike traditional adhesives that require extended drying times, super glue forms a solid bond within seconds. This quick-drying property makes it ideal for urgent fixes or projects that require immediate results.

3. Versatile Application

Super glue can be used for a wide range of household repairs. Whether you need to mend a broken ceramic figurine, fix a loose shoe sole, or reattach a small metal part, super glue provides a versatile solution. Its ability to bond different materials makes it a go-to adhesive for various DIY projects.

4. Cost-Effective

Compared to other types of adhesives, super glue is generally affordable. It offers excellent value for its adhesive strength and versatility. A small amount of super glue can go a long way, ensuring that you can tackle multiple repair tasks without breaking the bank.

5. Widely Available

Super glue is readily available in hardware stores, supermarkets, and online retailers. Its popularity has made it a commonly stocked item, ensuring easy accessibility whenever you need it. You can find super glue in different sizes and formulations to suit your specific repair needs.

6. Waterproof

Super glue forms a water-resistant bond, making it suitable for repairs in damp or humid environments. Whether you're fixing a bathroom fixture or an outdoor ornament, super glue's resistance to water ensures the durability of the bond even in moist conditions.

7. Heat and Chemical Resistance

Another advantage of super glue is its resistance to high temperatures and chemicals. It can withstand moderate levels of heat and exposure to common household chemicals without compromising its bonding strength. This feature makes it suitable for repairs in areas where other adhesives may fail.

8. Long Shelf Life

Super glue has a long shelf life if stored properly. When kept in a cool and dry place, unopened super glue containers can remain viable for an extended period. This ensures that you can have a reliable adhesive on hand whenever you need it, even if you don't use it frequently.

Disadvantages of Super Glue

1. Irreversible Bonding

Once super glue has dried and bonded two surfaces together, it becomes extremely challenging to separate them without causing damage. This irreversible bonding property can be a disadvantage if you need to make adjustments or disassemble the repaired item in the future.

2. Limited Gap-Filling Capability

Super glue works best when used to bond surfaces in close contact with each other. It has limited gap-filling abilities compared to other types of adhesives like epoxy. If you're dealing with uneven or mismatched surfaces, super glue may not provide the desired results.

3. Skin Irritation and Toxicity

Super glue can cause skin irritation if it comes into contact with the skin. It is important to handle it with care and avoid getting it on your hands or fingers. Additionally, some formulations of super glue contain toxic chemicals, so it is essential to read the product labels and follow safety precautions.

4. Potential Damage to Surfaces

While super glue is known for its strong bonding capabilities, it can potentially damage certain surfaces. Delicate materials like foam, fabric, or some types of plastics may be susceptible to discoloration or degradation when exposed to super glue. It is advisable to test a small, inconspicuous area before applying it to the entire surface.

5. Difficulty in Reversing the Bond

As mentioned earlier, super glue forms a nearly-indestructible bond. If you need to separate bonded items, it can be a challenging task. While there are some methods to break the bond, they may involve applying excessive force or using solvents that could damage the repaired item.

6. Short Working Time

Super glue has a short working time, which means you need to work quickly when applying it. Once the adhesive comes into contact with the air, it starts to polymerize rapidly. This limited working time can be a disadvantage if you're working on large or complex repairs that require precise adjustments.

7. Incompatibility with Certain Materials

Although super glue works well with many materials, it may not be compatible with all surfaces. Some plastics, such as polyethylene and polypropylene, have low surface energy and may not bond effectively with super glue. It is advisable to check the compatibility of the adhesive with the materials you intend to repair.

8. Sensitivity to Moisture

While super glue requires moisture to activate its bonding process, excessive moisture can interfere with its performance. High humidity levels or wet surfaces may affect the adhesive's ability to create a strong bond. It is essential to ensure that the surfaces to be bonded are clean, dry, and free from excessive moisture.


Super glue offers several advantages for household repairs, including its strong bonding capabilities, quick-drying nature, versatility, and cost-effectiveness. However, it is important to consider the disadvantages as well. The irreversible bonding, limited gap-filling capability, potential damage to surfaces, and sensitivity to moisture are factors that should be taken into account when using super glue. By understanding both the pros and cons, you can make informed decisions and utilize super glue effectively for your household repairs.

FAQs (Frequently Asked Questions)

  1. Can I use super glue on flexible materials like rubber or silicone? While super glue can bond some flexible materials, it may not provide a durable or flexible bond on rubber or silicone surfaces. It is advisable to use adhesives specifically designed for flexible materials.

  2. Is super glue safe to use on food-contact surfaces? No, super glue is not recommended for use on surfaces that come into direct contact with food. It is important to use food-safe adhesives that are specifically formulated for this purpose.

  3. Can I paint over a surface repaired with super glue? Yes, you can paint over a surface that has been repaired with super glue. However, it is advisable to ensure that the adhesive has fully cured and the surface is clean and prepared before applying paint.

  4. How can I remove super glue from my skin? If you get super glue on your skin, do not pull or force it off. Instead, soak the affected area in warm soapy water and gently peel or roll the adhesive away. Acetone or nail polish remover can also be used, but it is important to test it on a small area of skin first.

  5. Can I use super glue for outdoor repairs? Yes, super glue can be used for outdoor repairs. However, prolonged exposure to sunlight and extreme weather conditions may affect its durability. It is advisable to choose a weather-resistant formulation or consider alternative adhesives designed for outdoor use.
