Why does my nail technician use a primer?

Nail technicians use a primer to help acrylic nail extension products adhere better to the nail. Primers are special formulations that, if applied improperly, can cause nail damage. Therefore, it is a good idea to leave the application of primers in the hands of the nail technicians. Not all nail extensions require the use of a primer. Wrapped nails, such as fiberglass, silk and linen, or glue and powder applications do not require the application of a primer.
