Technique for working with hard gel on natural nails:
-
Perform a clean manicure and proper nail preparation (preferably using a soft file instead of a buffer).
-
Nails must be healthy and not overly thinned or damaged.
-
The thickness of the material at the free edge should be at least 1 mm.
-
For soft and flexible nails, file out the inner side of the nail enhancement to prevent lifting. The filed area should be sealed with a non-wipe top coat.
Reinforcement Technique “Sidewalls” with 4in1 BIAB Gel PNB:
- Remove the old coating and perform a manicure without shortening the nail length.
- Prepare the nail plate and disinfect it using Nail Prep PNB.
- Apply a very thin base layer (substrate) of 4in BIAB GEL PNB using rubbing motions and cure for 60 seconds.
- Reinforce the free edge using the “sidewalls” technique.
- Distribute 4in BIAB GEL PNB along the free edge from stress point №1 and the growth points to stress point №2. The thickness at the edge should be 1.5 mm along the entire perimeter. Stress points are the areas of the nail most affected by pressure and strain as the nail grows.
- Apply a modeling layer of 4in BIAB GEL PNB to fill the sidewalls and create the desired nail architecture. Cure for 90–120 seconds using half power mode.
- Remove the sticky layer using Gel Cleanser PNB and adjust the length.
- Cover with a gel polish color and create a design if desired.
- Apply Express/Protect/Powder/Shock/Art Top PNB to finish.
Important!
- The BIAB coating does not contain harmful adhesive ingredients; adhesion is achieved through the optimal volume of material in the stress zones. Therefore, using the “sidewalls” technique is essential for obtaining excellent results without using a primer.
- You can also use 4in BIAB GEL PNB in your usual gel-in-a-bottle strengthening techniques, provided you use a primer and an elastic base coat.
