Leathercraft Essentials: Contact Cement vs. Rubber Cement

Leathercrafting is an art that demands precision, skill, and the right set of tools and materials. Among the essential elements in a leatherworker's toolkit are adhesives, which play a crucial role in bonding various leather pieces together. Two commonly used adhesives in leathercrafting are contact cement and rubber cement. In this blog post, we'll delve into the key differences between these two types of adhesives and explore when to use each for optimal results in your leather projects.

Contact Cement 

Contact cement is a popular adhesive known for its strong and immediate bond. It typically comes in liquid form and is applied to both surfaces that need to be joined. One distinctive feature of contact cement is its ability to create an instant and robust bond when the two adhesive-coated surfaces are pressed together. This makes it an excellent choice for projects that require a quick and secure connection.

Pros of Contact Cement:

1. Quick bonding: Contact cement offers a rapid bonding process, saving time on your leathercrafting projects.
2. Strong bond: The bond created by contact cement is sturdy and durable, ensuring the longevity of your leather creations.
3. Versatility: Suitable for a variety of leather types and projects, contact cement can be used for bonding leather to leather, as well as leather to other materials.

Cons of Contact Cement:

1. Limited repositioning: Once the surfaces are joined, contact cement does not allow for repositioning, so precision is crucial during application.
2. Potentially toxic fumes*: Contact cement may emit strong fumes, so it's advisable to use it in a well-ventilated area or with proper respiratory protection.

* There are water based contact cements, like Eco-Weld Water Based Contact Adhesive, that can be a great option to reduce exposure to toxic fumes.

Rubber Cement 

Rubber cement, on the other hand, is a more flexible adhesive that remains tacky even after drying. It is often used in leathercrafting for projects that require a temporary bond or where repositioning is necessary. Rubber cement is typically applied to one surface, allowed to dry partially, and then the two surfaces are pressed together.

Pros of Rubber Cement:

1. Repositioning: Rubber cement allows for repositioning, making it suitable for projects that require adjustments before the final bonding.
2. Minimal residue: Rubber cement leaves minimal residue and is easy to remove from surfaces, making it a good choice for temporary bonds.
3. Flexibility: The flexibility of rubber cement makes it ideal for projects where the leather may need to stretch or move.

Cons of Rubber Cement:

1. Weaker bond: Compared to contact cement, rubber cement may not provide as strong a bond, making it less suitable for permanent connections.
2. Slower bonding: Rubber cement requires more time to set, so projects using this adhesive may take longer to complete.

Conclusion 

In the world of leathercrafting, the choice between contact cement and rubber cement depends on the specific requirements of your project. If you need a fast and strong bond for a permanent connection, contact cement is the go-to choice. On the other hand, if you require flexibility, repositioning, or a temporary bond, rubber cement offers the versatility you need. Understanding the characteristics and applications of each adhesive will empower you to make informed decisions, ensuring the success of your leathercrafting endeavors.
