Is Super Glue and Baking Soda Waterproof?

Super glue and baking soda are a surprising combination when it comes to adhesive strength and waterproof properties. While baking soda is typically known as a non-waterproof powder, when mixed with super glue, it creates a powerful and effective solution.

Keep reading to more about the effectiveness of this combination and why you should consider using it for your future projects.

Understanding Super Glue and Baking Soda

Super glue, also known as cyanoacrylate adhesive, is a strong, fast-acting adhesive that bonds porous and non-porous surfaces together. It forms a firm bond in a matter of seconds due to a chemical reaction with moisture present in the air.

Baking soda, on the other hand, is a common household ingredient widely used for cooking and cleaning. It is an alkaline substance that, when combined with an acidic ingredient, produces carbon dioxide and water. This reaction is typically observed when baking soda is combined with an acid such as vinegar.

The Combination: How Does It Work?

When super glue and baking soda are combined, the baking soda acts as a filler or reinforcement for the super glue. The baking soda absorbs the moisture present in the glue, accelerating its curing process and forming a hard, plastic-like substance. This resulting adhesive mixture is often referred to as “super glue epoxy.”

Potential Waterproofing Ability

The claim that super glue and baking soda create a waterproof seal primarily stems from the strong bonding properties of super glue. Super glue epoxy has been touted as a potential solution for repairing leaks, sealing cracks, or even creating watertight joints.

However, it is important to note that while the cured adhesive mixture may have a high resistance to water, it is not impervious to all forms of moisture. Water can still permeate through any gaps or cracks in the bond, compromising the waterproofing ability.

The Impressive Benefits of Super Glue and Baking Soda

Super glue is commonly used for various quick fixes due to its fast-drying nature and strong bonding capabilities. In its initial form, super glue is soft and comes in a liquid or gel state.

It relies on the moisture and humidity present in the air to activate its drying and curing process. Once fully dried and cured, super glue becomes waterproof.

Mixing baking soda with super glue offers several benefits that further enhance its adhesive properties. Baking soda acts as a catalyst for the super glue, causing it to dry and cure at an accelerated rate. This is particularly beneficial when time is a crucial factor in completing a project.

Furthermore, the addition of baking soda to super glue produces a stronger bond between the surfaces that need to be glued together. The resulting adhesive mixture outperforms regular super glue, making it an excellent choice for quick fixes that require maximum strength and durability.


The combination of super glue and baking soda creates a waterproof and highly effective adhesive solution. Adding baking soda to super glue enhances its drying and curing speed, allowing for faster completion of projects. Additionally, the mixture produces a stronger bond compared to using super glue alone. It is important to note that the super glue and baking soda mixture becomes waterproof only after the glue has fully set.

Considering the impressive benefits and enhanced strength of this mixture, incorporating baking soda into your super glue applications is a wise decision. It amplifies the glue’s existing properties, providing faster drying and curing times, as well as forming a more durable bond. Whether you are working on a quick fix or a larger project, the combination of super glue and baking soda will undoubtedly exceed your expectations.
