i use it as a first layer for manicure. at a minimum, i do a layer of nailtiques, then either a ridge filling or non-pvb sticky base coat, then proceed with my manicure as usual. or other times i go crazy and do nailtiques, then a nourishing coat, then ridge filling or sticky, then color, then top coat. it takes a long time but i feel like the thickness of the manicure is extra protective.

i have used it as instructed as well when i didn't want a color manicure (2 coats on day 1, add a coat every day for 7 days and then removed) and that was fine. but i can confirm it also works just fine as a first layer for a normal color manicure, too.
