To apply acrylic nails you should first prepare the nail surface by removing any old nail polish. You should then buff out the nail so that any ridges are removed. Wash your hands to remove any residue. You can then begin the application for your new acrylic nails. There are various sizes so first make sure to choose the nail that properly fits each finger. You then take nail adhesive that comes in a tube similar to crazy glue. Put the glue on the acrylic nail and then place it on top of your real nail. Hold in place for ten to fifteen seconds and you are done. It is very hard to remove the glue so make sure you make any adjustments quickly.
