What grit number is used to produce a high gloss shine on nails?

To achieve a high gloss shine on nails, a grit number of 240 is typically used. This level of grit represents a fine sandpaper that smooths the nail surface effectively while minimizing any roughness that could dull the overall finish.

Using 240 grit sandpaper allows nail technicians to refine the surface and prepare it for polishing, creating a shiny, polished appearance. The finer the grit number, the smoother the surface it creates, leading to a more reflective shine when coupled with a top coat.

Grit numbers like 120 and 180 are coarser and are usually employed for shaping and shortening nails rather than finishing. A grit number of 400, while it may seem finer, is often used for polishing purposes but may not effectively contribute to the initial smooth surface needed before applying any shine products. Thus, 240 grit strikes the right balance for producing that high gloss finish on nail surfaces.
