Is Super Glue Waterproof? Everything You Need to Know

When it comes to bonding materials together, super glue has become a popular choice for its strong adhesive properties. But what about its durability when exposed to water? Can super glue hold up against the elements and maintain its strength?

Let us explore whether super glue is truly waterproof and provide you with all the information you need to know.

Understanding Super Glue

Before diving into the waterproof aspect, let’s first understand what super glue is and how it works. Super glue, also known as cyanoacrylate adhesive, is a type of fast-acting adhesive that creates a strong bond between surfaces.

It is commonly used for various purposes, including fixing broken objects, crafting projects, and even in medical applications.

How Does Super Glue Work?

Super glue works by forming a bond through a process called polymerization. When the glue comes into contact with moisture, it starts to solidify and form long chains of molecules, creating a strong adhesive bond.

This process happens quickly, which is why super glue can bond surfaces almost instantly.

Is Super Glue Waterproof?

Yes, super glue is considered to be waterproof to a certain extent. Once it is applied and fully cured, it will resist removal by water or mild solvents. However, it is important to note that while it is water-resistant, it is not entirely waterproof.

Super glue can withstand exposure to water under normal conditions, and some types of super glue may even hold up in saltwater. The bond strength of the super glue will depend on the specific type of glue used and how long it is allowed to dry.

It’s worth mentioning that water can still have an effect on the glue over time, so it’s important to consider the specific requirements of your project before using super glue in wet or submerged conditions.

Factors Affecting Water Resistance

While some super glues are indeed waterproof, it is important to consider a few factors that can affect their water resistance:

  1. Quality of the Glue: The quality of the super glue plays a crucial role in determining its water resistance. Choosing a reputable brand known for producing high-quality adhesives can ensure better performance when exposed to water.
  2. Application Method: The way super glue is applied can also impact its water resistance. Properly cleaning and preparing the surfaces before bonding will help create a stronger and more waterproof bond.
  3. Type of Material: Different materials react differently to water and adhesives. Some materials may absorb water, causing the bond to weaken over time. It is essential to consider the compatibility of super glue with the materials being glued together.

Best Practices for Water Resistance

To maximize the water resistance of your super glue bond, here are a few best practices to keep in mind:

  1. Ensure surfaces are clean, dry, and free from any contaminants such as oil or grease before applying the super glue.
  2. Apply a thin and even layer of super glue on both surfaces to be bonded.
  3. Press the surfaces together firmly and hold them in place for the recommended curing time. This will allow the glue to create a strong bond.
  4. Avoid exposing the glued object to water for at least 24 hours, allowing the super glue to fully cure and reach its maximum strength.
  5. Consider using specialized waterproof super glue for applications where water resistance is critical.


Is Super Glue Waterproof When Dry?

Super glue is not completely waterproof when dry. While it has some water resistance, prolonged exposure to water can weaken the bond1. The glue can start to break down and the bond between surfaces may weaken. It is important to note that the level of water resistance can vary depending on the specific brand and type of super glue used.

Is Super Glue Waterproof on Plastic?

Super glue can bond well with various surfaces, including plastic. However, not all super glues are specifically designed to work optimally on plastic. It is important to choose a super glue that is suitable for bonding plastic surfaces. Some brands offer specialized super glue formulas designed specifically for plastic bonding, providing better adhesion and water resistance.

Is Gorilla Super Glue Waterproof?

Gorilla Super Glue is designed to have high water resistance. It is formulated to withstand moisture, making it suitable for applications where water exposure is expected. However, it is essential to follow the specific instructions provided with the product for optimal performance.

Is Loctite Super Glue Waterproof?

Loctite Super Glue is known for its strong bonding properties, but not all variants are explicitly labeled as waterproof. Some Loctite super glues may have a certain level of water resistance but might not be completely waterproof. It is important to check the specific product label or description for its waterproof properties.

Is Super Glue Waterproof After It Dries?

Super glue’s water resistance can diminish over time, especially with prolonged exposure to water. While it may initially resist water, repeated exposure or extended immersion in water can weaken the bond. It is important to assess the specific circumstances and consider using specialized waterproof super glue for applications requiring long-term water resistance.

Will Super Glue Stop a Water Leak?

Super glue is not typically recommended for stopping water leaks. While it can temporarily seal small cracks or leaks, it is not intended or designed for use in plumbing or water-related repairs. For sealing water leaks or plumbing repairs, it is advisable to use specialized products designed specifically for those purposes.

What Glue Holds in Water?

Certain types of adhesives are specifically formulated to hold in water. Marine-grade adhesives, epoxy adhesives, and some types of silicone adhesives are known for their water-resistant properties. These adhesives are designed to withstand exposure to water, making them suitable for applications where water resistance is important.

Is Super Glue Permanent?

Super glue forms a strong bond and is generally considered to be a long-lasting adhesive. However, its permanence can be influenced by factors such as the materials being bonded, the application method, and the conditions to which the bond is subjected to. In some cases, the bond created by super glue can be considered permanent, but it may also be possible to remove or dissolve the glue under certain circumstances.

While not all super glues are completely waterproof, there are specialized varieties available that offer enhanced resistance to water. The water resistance of super glue depends on factors such as the quality of the glue, application method, and the materials being bonded. By following best practices and considering the specific requirements of your project, you can create a strong and water-resistant bond using super glue.
