No, Fibrique Express Repair does not require a bonding agent, as it already contains 50% bonding properties. It is not necessary to use any LCN bonding agents (Bonder Intense, Bio Bond or Base Bond) prior to using Fibrique Express Repair, as this would cause the Fibrique to slide off the nail and will cause lifting issues.  It is also important to gently stir Fibrique Express Repair before application as the bonding agent in this product tends to float to the top, and the fibers tend to sink to the bottom of the jar.  Recommended use on normal to hard nails and best used for thin overlays and repairs due to its minimal flexibility.
