DND Gel Polish - 604 Cool Gray
Couldn't load pickup availability
DND #604 Cool Gray is an unexpected cool soft gray from DND's original gel and lacquer line, the one with more than 1,000 numbered shades. Choose the gel alone, the gel with its matching lacquer, or the lacquer on its own.
What you get
- Gel Polish Only: one 0.5 fl oz (15 mL) gel bottle
- Lacquer Only: one 0.5 fl oz (15 mL) air-dry lacquer
- Gel Polish & Lacquer: the gel bottle and the matching lacquer, 0.5 fl oz (15 mL) each
Why techs stock it
- Air-dry lacquer: the lacquer needs no lamp, handy for pedicures and quick polish changes.
- Professional bottle size: each bottle holds 0.5 fl oz (15 mL), the standard salon size rather than a mini.
- Matched by number: the gel and the lacquer share one shade number, so reorders and client records stay simple.
- Opaque in two coats: a cream finish covers the nail in two thin coats.

Who it suits

- Short nails, paired with a matte top coat.

Which option to choose
Choose Gel Polish Only if you only run gel services, Gel Polish & Lacquer if you also do pedicures or sell take-home bottles, and Lacquer Only for regular polish services. All three are the same Cool Gray shade.
Thin coats win
Most chipping comes from one heavy coat that never cured all the way through. Two thin coats of 604 wear longer than one thick one.
More to pair with Cool Gray: DND gel colours, DND gray shades and DND, DC and DIVA base and top gels.
Frequently Asked Questions
Does the lacquer match the gel exactly?+
Yes. DND mixes DND #604 Cool Gray as a gel and a lacquer with the same shade number, so a gel manicure and a lacquer pedicure match. The lacquer air-dries, the gel needs an LED or UV lamp.
What colour is Cool Gray?+
DND #604 Cool Gray is an unexpected cool soft gray. Screens show colour differently, so check a swatch stick against the client's skin before the full set.
How long do I cure each coat?+
Under an LED lamp, cure each thin colour coat 30 to 60 seconds; a UV lamp takes about 2 minutes. Thin coats cure all the way through, thick ones do not.
Which base and top coat should I use?+
DND recommends DND Base #500 and DND Top #600 No Cleanse. DND, DC and DIVA base and top gels are cross-compatible, so any of them will work.
