❗️Too much adhesive will cause the fan to close, making it harder to place on the NL, it is more likely to twist to the side. The extra adhesive will add weight, so there is more likelihood for lash damage.
❗️Too little adhesive will result in bad retention.
❗️Dip the fan in the middle of the adhesive drop, not more than a mm in. Pull out quickly and apply. Most adhesives have 1-2 sec drying time, so the faster you apply the fan on the NL the better chance you have in applying it correctly and achieving better bond.
