Medium viscous, clear, flexible, and strongly adhesive base gel that can be removed if needed. Apply the strongly adhesive base gel thinly to the nail after Nail Prep / Spray Prep and Primer / Primer Acid Free / Primer HEMA free. The base gel can be applied under both gel and 3 Step polishes, as well as the Xtreme Fusion Gel. It prevents the material from lifting off the nail plate when the nail is bent. Curing: 2-3 minutes under UV, 1-2 minutes under LED (depending on the strength of the lamp)
