STEP BY STEP

1. Chemical Prep. This step is essential for ensuring long-lasting wear. Use Kinetics Cleanser, a 2-in-1 cleanser and dehydrator, to thoroughly clean the nail plate and eliminate oils and moisture. For oily or problematic nails, double cleansing is recommended. For more precise work on a nail plate you can use a Dehydrator.
Optionally, follow with an application of acid-free Bonder. Acting like double-sided sticky tape, it ensures maximum adhesion.

2. How Much Product to Use? Less is more. Always use a small amount of product. Gently wipe the brush against the neck of the bottle to remove any excess before application.
3. Application Before Gel Polish Color. Use a minimal amount of Rubber Base+ and apply it with gentle rubbing motions to ensure it bonds well with the natural nail. Leave a small gap around the cuticle—this gives your color space to flow into place neatly. Without curing the first layer, reload your brush and apply a very thin second layer to build a light structure. Use a detail brush and work with the reflection from the lamp to smooth the surface. Flip the hand if necessary and let the gravity work. Cure for 30 seconds in a UV/LED lamp.
Note: A structured layer does not mean a thick layer!

4. Application Before Gel Polish Color Using a Gel Brush (Optional).
Using a gel brush can offer better control. Start with a small amount of product and rub it gently into the nail. Leave a small gap around the cuticle. Without curing, reload the brush from the bottle and apply a thin second layer to build structure. Smooth the surface using a detail brush and the lamp reflection. Optionally, flip the hand to allow gravity work. Cure for 30 seconds in a UV/LED lamp.
5. Application Before Hard Gel. When using Rubber Base+ under Hard Gel or Gel in Bottle, you’re not building structure—but you do need slightly more product to create a cushion for proper adhesion. A scrub layer alone won't be sufficient.
Ensure full coverage: wherever you apply the hard gel, the base must be underneath. Start by applying a small amount with a gel brush, rubbing it into the nail. Do not cure.
Then, use the brush from the bottle to apply a thin, even layer over the surface. Cure for 30 seconds in a UV/LED lamp.

6. Common mistakes.
Correct product amount and hand positioning are essential for strong, lasting results.
Incorrect finger position – especially when flipping the hand – can cause the base to float unevenly to one side.
Using too much product – this can cause pooling, uneven structure, and lifting.
