How To Use:

1. Nail Prep: Sanitise your hands and your client’s. Push back the cuticles using the ProPrep Cuticle Pusher and trim excess with the ProNip Cuticle Nippers. Shape nails with a TGB 220/240 File, gently buff with a TGB 100/180 Buffer, and cleanse with 100% acetone.

2. Optional Base Layer: Apply a thin layer of TGB HEMA-free Bond Base or Rubber Base for extra retention. Cure in the TGB Light The Way Nail Lamp on Low Heat Mode for 99 seconds.

3. First Layer: Apply a thin, even layer of Hard BIAB to the natural nail. Cure for 99 seconds in Low Heat Mode.

4. Second Layer (Building the Structure): Apply a medium bead of Hard BIAB, spreading side to side and pulling away from the cuticle area. Turn the hand to help create the apex. Cure each nail individually for 99 seconds.

5. Third Layer (Optional for Added Strength): Repeat the second layer process for extra durability. Cure again for 99 seconds.

6. Refine the Nail: Remove the tacky layer using acetone or isopropyl alcohol. Shape using a TGB 120/180 File and smooth with a 100/180 Buffer. Focus on refining the cuticle area and free edge. Remove dust and cleanse again.

7. Top Coat & Finish: Apply TGB Gel Colour if desired, following gel polish steps. Seal with your chosen TGB Top Coat and cure for 60 seconds. Finish with TGB Cuticle Essence, avoiding the nail to prevent top coat dulling.
