Disposable white files for straight base EXPERT 20 Staleks, grit 180, x 30

STALEKS EXPERT 20 disposable white files in 180 grit, the natural nail grit

The STALEKS EXPERT 20 disposable white files in 180 grit are the self-adhesive abrasive strips designed for the MBE-20 and SPBE-20 straight bases, in a 140 x 18 mm format, on a soft foam layer and in a pack of 30 pieces. This is the grit a nail technician uses most often on the natural plate: the grit of a finished shape, of an even free edge and of a manicure carefully prepared before colour goes on.

Why 180 is the reference on a natural plate

A natural nail cannot be treated like an enhancement. It is thin, it reacts to heat and it does not forgive abrasives that are too aggressive, which leave micro tears along the edge and weaken it. This grit sits exactly in the right place: efficient enough to redraw a shape in a few passes, measured enough not to fray the free edge.

In practice it takes a bitten or broken nail back to a clean line, evens out length that varies from one finger to the next, and leaves a regular edge that will not catch on clothing. It is also the grit you reach for at a touch-up appointment, when a client comes back with a single snag to sort out rather than a whole service to redo.

Working the free edge without weakening it

The movement matters as much as the abrasive. On a natural nail, file from the side towards the centre, avoid any sawing motion, work on a dry nail and never straight after a soak. The strip is presented slightly tilted under the free edge to draw the line, then brought upright to smooth the cut.

Finishing then means passing very briefly along the underside of the edge to remove the threads that always remain there. Many technicians follow this grit with a finer abrasive from the same range to soften the edge further, particularly on thin nails.

Preparing a gel polish application

Before colour, the shape has to be settled, and that is exactly this grit's job. Length is fixed, the line is clean, the corners are softened, and the material no longer needs touching once the base coat is on. A nail shaped at 180 offers a regular edge on which the capping will hold without catching.

The same grit also lets you tidy up the outline of a reinforced nail, where a thin layer of product has been laid down to support a soft plate: the abrasiveness is enough to correct the contour without lifting the reinforcement.

Straight bases, soft foam, a 140 x 18 mm strip

These refills are cut for the two straight holders of the series, the MBE-20 and the SPBE-20. The metal gives the stiffness a clean straight line needs, while the soft foam interlayer under the abrasive absorbs part of the pressure: on a curved natural plate, that give stops the corner of the strip from marking the surface. The client experiences a gentler service and the technician keeps control of the line.

A single-use abrasive, a base on protocol

Every strip belongs to one client. It is not washed, not disinfected and not stuck back on once lifted: adhesive and abrasive are designed for one service, no more. At the end of the appointment it joins the treatment waste, while the metal base follows the usual salon route of cleaning, then disinfection, then sterilisation.

The routine is visible to the client and easy to explain: she sees a clean strip come out of its packaging, exactly like a drill bit taken from its pouch. On natural nail work, where the edge is sometimes filed very close to the surrounding tissue, that rigour is anything but a detail.

Application and removal in practice

1. A clean, dry, disinfected base is the starting condition.
2. Take the protective backing off the 180 grit strip.
3. Lay the strip edge to edge on the base, then smooth it from one end to the other so no bubble is trapped.
4. Carry out the service, brushing the dust away as soon as the abrasive loads up.
5. Take the strip by a corner, peel it off and bin it.
6. Put the base through cleaning, disinfection and sterilisation.
