Why is floral adhesive considered waterproof once dry?

Floral adhesive is considered waterproof once dry because it forms a barrier against moisture. When the adhesive dries, it solidifies into a strong, water-resistant material that can withstand exposure to water and humidity without breaking down or losing its effectiveness. This property is crucial for floral arrangements, especially those that may encounter water through methods like watering plants or placement in humid environments. The waterproof nature helps ensure that the structural integrity of the arrangement is maintained, allowing the flowers to remain securely fixed in place without the risk of the adhesive dissolving or weakening over time due to moisture.

Other options, while related to the function of floral adhesives or the characteristics of certain adhesives, do not accurately describe why the adhesive is labeled as waterproof. For instance, while holding flowers firmly is an essential function, it does not inherently provide waterproof qualities. Preventing flowers from wilting and being made from natural ingredients pertain to different aspects of floral care and composition but do not explain the waterproof characteristic of the adhesive itself.
