Description

French Base 374 is a porcelain-effect cover base from Slowianka Nail Trends, part of the premium Strong Cover Base Line — a collection renowned for its high durability and strong reinforcing properties.

This base is designed for building, sealing and strengthening the natural nail plate. Once cured, it significantly stiffens the nail, making it suitable not only for normal nails but also for problematic nail plates, including uneven or deformed nails, as well as nails that are thin, soft or prone to breaking.

Key features:

  • Porcelain-effect coloured base.
  • Medium-thick consistency and medium viscosity.
  • High adhesion — wear time up to 4 weeks without lifting or air pockets.
  • Strong reinforcing and stiffening effect.
  • Suitable for long, soft and weak natural nails.
  • Ideal for building, sealing and strengthening.
  • Allows nail building up to 1 mm in a single application.
  • Further building possible with additional layers.
  • Gentle cushioning effect after curing.
  • Medium acidity (pH level approx. 4).

French Base 374 offers excellent application control thanks to its medium viscosity, ensuring fast and precise work around the cuticles without stringing. Using this base, the natural nail can be extended by up to 2 mm.

Curing time in a LED lamp is a minimum of 90 seconds. A lower dispersion layer can be achieved by extending the curing time. Any remaining light dispersion should be cleansed with a cleaner to ensure proper adhesion of subsequent products.

The base provides 10–20% UV protection. In cases of strong or prolonged sun exposure (e.g. extended holidays), Slowianka Nail Trends recommends finishing the manicure with Pro White Top to prevent pigment migration. Under standard conditions, other Slowianka Nail Trends top coats are fully compatible.

Colour description:

French Base 374 is a light, cool-toned, universal pink shade — perfect for classic French manicures and baby boomer designs. It is especially flattering on lighter skin tones and naturally light nail plates, while also working well with darker tones. Pigmentation level: 60–70%, providing strong yet elegant coverage.

Additional information:

  • The product may slightly separate after prolonged storage — this does not affect its quality or performance.
  • Stir gently before use to restore a uniform consistency.

French Base 374 is an excellent choice for nail professionals seeking strength, control and a flawless base for timeless, elegant nail styles.
