Gumpaste, a popular medium in cake decorating, allows for the creation of intricate sugar flowers, decorations, and figurines. Its unique composition, consisting of confectioners’ sugar, water, edible gum, and sometimes additional ingredients, makes it pliable and ideal for molding and shaping. However, achieving proper adhesion is crucial for successful gumpaste creations. This article provides a comprehensive guide to understanding gumpaste, its properties, and effective adhesion techniques.
Definition and Composition
Gumpaste is a type of sugar paste used in cake decorating. It is made by combining confectioners’ sugar with water, edible gum (such as tylose or CMC), and potentially other ingredients like corn syrup or egg whites. The edible gum acts as a binder, providing strength and flexibility to the paste.
Kneading and Conditioning
Kneading and conditioning gumpaste are essential steps before using it. Kneading helps to activate the gum and distribute it evenly throughout the paste, making it pliable and easy to work with. This process also helps to remove any air bubbles that may cause weakness in the final product.
Proper Consistency
Achieving the right consistency is crucial for successful gumpaste adhesion. The paste should be pliable and smooth, similar to modeling clay, without being overly sticky or dry. If the gumpaste is too sticky, it may become difficult to work with and may not adhere properly. If it is too dry, it may crumble and break easily.
Adhesion Techniques
There are several effective techniques to make gumpaste stick together:
a. Water: Brushing a small amount of water onto the surface of the gumpaste pieces helps create a sticky surface for adhesion. However, it is important to use water sparingly, as too much can dissolve the gumpaste and weaken the bond.
b. Edible Glue: Edible glue, a mixture of water and edible gum (such as tylose or CMC), is a commonly used adhesive for gumpaste. It provides a strong bond and can be applied using a small brush or a fine-tip applicator bottle.
c. Tylose/CMC Paste: Adding a small amount of tylose or CMC powder to gumpaste can increase its adhesive properties. These edible gums act as binders and help the gumpaste adhere more efficiently.
Drying and Setting
After assembly, gumpaste creations need time to dry and set properly. Larger or delicate pieces should be supported with foam or tissues until they harden. This prevents them from collapsing or losing their shape.
Troubleshooting
If gumpaste pieces are not sticking together firmly, there are a few potential causes:
- Incorrect Consistency: The gumpaste may be too dry or too wet. Adjust the consistency by adding more water or kneading in more gumpaste, as needed.
- Insufficient Adhesive: Ensure that enough water, edible glue, or tylose/CMC paste is used to create a strong bond between the pieces.
- Dirty Surfaces: Clean the surfaces of the gumpaste pieces before attaching them to remove any dust or debris that may prevent adhesion.
Tips and Tricks
- Allow the gumpaste to rest for a few minutes before using it. This helps to relax the paste and make it more pliable.
- Store gumpaste properly in an airtight container to prevent it from drying out or absorbing moisture from the air.
- Work in a cool and dry environment to prevent the gumpaste from becoming too sticky or soft.
Conclusion
Achieving strong adhesion with gumpaste is essential for creating beautiful and long-lasting cake decorations. By understanding the properties of gumpaste, using proper adhesion techniques, and following these tips and tricks, cake decorators can create stunning gumpaste creations that will impress and delight.

FAQs
How do you make gumpaste stick to itself?
There are several effective techniques to make gumpaste stick to itself:
- Water: Brush a small amount of water onto the surface of the gumpaste pieces to create a sticky surface for adhesion. Be careful not to use too much water, as it can dissolve the gumpaste.
- Edible Glue: Use edible glue, a mixture of water and edible gum (such as tylose or CMC), to attach gumpaste pieces together. Apply the glue using a small brush or a fine-tip applicator bottle.
- Tylose/CMC Paste: Add a small amount of tylose or CMC powder to gumpaste to increase its adhesive properties. These edible gums act as binders and help the gumpaste adhere more efficiently.
Why won’t my gumpaste stick together?
There are a few possible reasons why your gumpaste may not be sticking together:
- Incorrect Consistency: The gumpaste may be too dry or too wet. Adjust the consistency by adding more water or kneading in more gumpaste, as needed.
- Insufficient Adhesive: Ensure that you are using enough water, edible glue, or tylose/CMC paste to create a strong bond between the pieces.
- Dirty Surfaces: Clean the surfaces of the gumpaste pieces before attaching them to remove any dust or debris that may prevent adhesion.
How do you make edible glue for gumpaste?
To make edible glue for gumpaste, you can mix the following ingredients:
- 1/4 cup warm water
- 1/2 teaspoon tylose powder (or CMC powder)
Combine the warm water and tylose powder in a small container and stir until the powder is completely dissolved. The mixture should have a syrup-like consistency.
Can I use water to make gumpaste stick?
Yes, you can use water to make gumpaste stick. However, it is important to use water sparingly, as too much water can dissolve the gumpaste and weaken the bond. It is also important to note that water may not be as effective as edible glue or tylose/CMC paste for creating a strong adhesion.
