Start with any kur base coat. Once the first layer has dried, apply 1-2 coats of lakur as needed. Let each layer of lakur fully dry for 2-3 minutes before applying the next layer, then seal with any kur top coat. To expedite the drying process, apply 1-2 drops of Accelerating Drying Oil at the cuticle and allow the oil to run to the free edge of the nail.

For best results, reapply top coat every 3-4 days to lock in color and help extend wear time.
