How Often Should Acrylic Nails Be Filled. You should get them done every two weeks. Acrylic nails aren't designed to last more than two weeks.
A: Nail technicians use a primer to help acrylic nail extension products adhere better to the nail. You should get them done every two weeks. The acrylic life is a committed life, and if you're not ready to get to a salon every two to three weeks for a fill, then it's best not to start.
By keeping the nails trauma free, the healthy conditions of the nails should not be affected with regular fill maintenance.
Therefore, it is a good idea to leave the application of primers in the hands of the nail technicians.
Despite these advantages, acrylic nails are not meant to last forever. Soak, file, repeat — and be patient. When the solution dries, there isn't a visible gap between the acrylic nail and your natural nail.
