Tips and Tricks for Working with CA Glue with Activator

Understanding Super Glue

Super glue, also known as cyanoacrylate adhesive, is a fast-acting adhesive that forms a strong bond between surfaces. It works by reacting with moisture present in the air and on the surfaces being bonded. Super glue is available in various viscosities, allowing it to be used for different applications.

Preparing the Surfaces

To ensure a long-lasting bond with super glue, it is crucial to prepare the surfaces properly. Follow these steps:

  1. Clean the surfaces: Remove any dirt, dust, grease, or moisture from the surfaces you plan to bond. Use a mild detergent or rubbing alcohol to clean them thoroughly.
  2. Roughen smooth surfaces: Smooth surfaces may not provide enough texture for the glue to adhere to. Gently sand or score the surfaces to create a rougher texture that promotes better adhesion.
  3. Fit the surfaces together: Before applying the glue, ensure that the surfaces fit together properly and align them correctly. This will help in achieving a strong bond.

Applying the Super Glue

Proper application of super glue plays a vital role in its effectiveness. Follow these guidelines:

  1. Apply a small amount: Super glue works best in thin layers. Apply a small drop of glue to one of the surfaces. Remember that a little goes a long way.
  2. Spread evenly: Use a disposable applicator, toothpick, or the nozzle of the glue tube to spread the glue evenly across the surface. Avoid applying too much pressure, as it can squeeze out excess glue and create a messy bond.
  3. Use in moderation: Apply only the amount of glue necessary to create a bond. Excessive use of glue can weaken the bond and make it prone to failure.

Proper Clamping and Drying

Clamping the bonded surfaces together during the drying process enhances the bond strength. Follow these steps:

  1. Align and press surfaces firmly: Once the glue is applied, carefully align the surfaces and apply firm pressure for a few seconds. This will help the glue spread evenly and ensure a strong bond.
  2. Use clamps or weights: If necessary, use clamps or weights to hold the surfaces together during the drying process. Follow the manufacturer's instructions regarding the recommended drying time.
  3. Allow sufficient drying time: Super glue sets quickly, but complete curing may take several hours. Avoid disturbing or stressing the bond until it has fully dried.

Enhancing Bond Strength

To make your super glue bond even stronger, consider the following techniques:

  1. Use an activator: Some super glues work in conjunction with an activator spray. Apply the activator to one surface before applying the glue to the other surface. The activator promotes faster bonding and increases bond strength.
  2. Mix with baking soda: For gap-filling applications, you can mix super glue with a pinch of baking soda to create a stronger and more durable bond. The mixture creates a quick-drying filler that fills gaps and provides added strength.

Avoiding Moisture and Temperature Extremes

Super glue is sensitive to moisture and temperature. To ensure a longer lifespan for your bond, follow these precautions:

  1. Keep surfaces dry: Moisture can interfere with the curing process of super glue. Ensure that the surfaces to be bonded are completely dry before applying the glue.
  2. Avoid extreme temperatures: High temperatures can accelerate the curing process, while low temperatures can slow it down. Optimal bonding conditions usually range between 50°F (10°C) and 80°F (27°C).

Storage and Shelf Life of Super Glue

Proper storage of super glue can extend its shelf life and maintain its effectiveness. Consider the following tips:

  1. Seal the container tightly: After each use, wipe the nozzle clean and seal the container tightly. This prevents air exposure and keeps the glue from drying out.
  2. Store in a cool, dry place: Super glue is best stored in a cool, dry place away from direct sunlight. Extreme temperatures and humidity can degrade its adhesive properties.

Removing Super Glue

If you need to remove super glue from a surface, follow these steps:

  1. Soak in warm, soapy water: For non-porous surfaces, soak the bonded area in warm, soapy water for a few minutes. Gently peel or rub off the glue residue with your fingers or a soft cloth.
  2. Use acetone or nail polish remover: For stubborn or cured glue, apply a small amount of acetone or nail polish remover to a cotton swab or cloth. Gently rub the glue until it starts to dissolve. Be cautious not to damage the surface, especially for delicate materials.


By following these tips and techniques, you can significantly enhance the longevity and strength of your super glue bonds. Proper surface preparation, application, clamping, and drying play crucial roles in ensuring a successful and long-lasting bond. Additionally, taking precautions to avoid moisture, extreme temperatures, and storing the glue correctly can further prolong its effectiveness. With these practices in place, you'll be able to make the most out of your super glue and complete your projects with confidence.


1. Can I use super glue on all materials? Super glue can bond to a wide range of materials, including wood, metal, plastic, ceramic, and glass. However, it may not be suitable for certain types of rubber or silicone.

2. How long does it take for super glue to dry? Super glue sets quickly, usually within seconds to minutes. However, complete curing may take several hours, depending on the specific product and bonding conditions.

3. Can I use super glue for outdoor applications? While super glue can withstand some outdoor conditions, prolonged exposure to moisture and UV radiation may degrade its adhesive properties. Consider using specialized outdoor adhesives for long-term outdoor applications.

4. Is super glue waterproof? Super glue is water-resistant, but it may not be entirely waterproof. It can withstand occasional exposure to water, but prolonged immersion or continuous exposure may weaken the bond.

5. Can I reuse a container of super glue once it's been opened? Super glue containers are designed for single-use applications. Once opened, the glue can dry out quickly, making it less effective. It's best to use a new container for subsequent applications.
