I've done a few sets of glitter Bio, both full nails and tips.
Full nails - thin layer of clear gel and cure....another thin layer, then with small scoop / spoon (I used the chisel end of cuticle pusher!) sprinkle gel over nail whilst over foil (extra gel that falls off can be re-used) then cure. Quick dust with soft brush and another thin layer gel - sanitise, file to smooth out any lumps (don't panic that it goes dull at this stage) and then S-gel to bring up shine again and seal.
Glitter tips - similar to above but applied clear gel to nail, cured sanitised, slight buff, then applied clear gel to tip only, sprinkled glitter, backswiped with clean brush to give neater edge and cured. Dust again and now use clear gel again over nail bed, as tip is a little thicker than rest of nail now, to re-build curve of nail, and finish as above.
Looks fab - and no need to start mixing!
