I just purchased No Lift Nails primer. The instructions say to “use sparingly.” How much should be used per nail?

I just purchased No Lift Nails primer. The instructions say to “use sparingly.” How much should be used per nail?

We recommend using the brush that comes with the primer or any other small brush. To use, lightly rough up the nail, remove the dust and place the brush just behind the free edge and let the primer flow onto the nail to the cuticle, being careful not to touch the skin. Don’t flood the nail. Let it dry. The second application should dry to a matte finish, then apply your acrylic or UV gel. — Larry Gaertner is president of No Lift Nails Inc.
