Dip liquids 1, 2, 3, 4 explained: base, activator, top coat and brush saver

The dip liquids in plain English

A dip system has a powder and a short set of liquids, always used in the same order. The names change from brand to brand, but the jobs do not. Every system has some version of these four, and some leave one out.

Many brands also sell a brush saver, a separate bottle for keeping the base brush usable. Read the label on yours for how to use it.

All our dip liquids are on one shelf: dip liquids.

The numbers are not the same in every brand

The numbers (#1, #2, #3, #4) tell you the order within one brand. They do not mean the same thing across brands. A bottle labeled #3 might be an activator in one line and a top coat in another. Here is how the lines we carry are numbered:

That table lists what we stock on the shelf today. Your brand's own directions for the full sequence always win. When in doubt, read the bottle caps and match the step name, not just the number.

A quick buying checklist

• Pick the brand first, then buy every liquid in that line. Do not buy a lone activator "to try".
• Match the powder to the liquids you plan to use. OPI and NexGen are our dedicated dip powders, and AIO powders (Chisel, Le Lilia, DND DIVA) are usable as dip but read the jar.
• Check that you have every step in the list above, not just the base and top coat. A missing activator is the most common reason a first dip fails to harden.
• Buy a brush saver and a pack of lint-free wipes at the same time, since you will use both from the first set.

The order, step by step

1. Prep or bond (if your system has one) on a clean, dehydrated nail.
2. Base, one thin coat at a time, each followed by powder.
3. Activator after the last powder layer. Cap the free edge.
4. File and buff. OPI uses 180 grit to shape, then 100 and 220 grit buffers.
5. Activator again to reseal the filed surface.
6. Wait. OPI says a few minutes. A supplier guide says at least 60 seconds after the last activator, then wipe with a lint-free wipe.
7. Top coat in thin strokes. Two thin coats beat one thick one.

The full walkthrough with prep and aftercare is in the dip powder guide.

Can you mix brands of dip liquids?

The safe answer is no. An exam-prep guide for nail techs says to use only one manufacturer's products together, because mixing brands can cause an uncontrolled reaction and lifting. Dip liquids are chemically matched: base and activator are designed to react with each other, and top coats are designed to react with their own brand's activator. OPI describes it exactly this way for its system.

Powder is more flexible than liquid. Many people use a powder from one brand over another brand's base, and some AIO powders are formulated for dip systems from other brands. Even so, if you see lifting, dull top coat, tacky surface or white haze, the first thing to try is the full system from one brand. See why dip powder chips or lifts.

If you only need one bottle (say your activator ran out), buy the same brand and the same line. Do not substitute a different brand's activator because the label says activator.

Brush saver and keeping bottles working

Dip liquids are meant to harden. The base coat brush hardens every time it is left with product on it, and an activator that gets into the base bottle turns the base thick and stringy.

• Wipe the neck of every bottle and the brush before closing. A supplier troubleshooting guide lists carrying activator into the base as a cause of hardening base coat and brushes that harden.
• Keep each liquid to its own brush. Never use the base brush to touch the activator.
• Use a brush saver if you do many sets. We stock Kiara Sky Brush Saver and SNS Brush Saver Plus. Follow the instructions on the bottle.
• Store liquids upright with the caps closed. Replace any liquid that no longer flows like water.

What goes wrong when a liquid is wrong or old

Shelf life: a supplier guide gives powder a shelf life of about three years in cool, dark storage. For liquids, check the printed date or batch code, and replace any bottle that has changed texture.

Worked example: where each OPI liquid goes

OPI's Powder Perfection is the clearest published example of a three-liquid system. The sequence on OPI's own pages is:

1. Base Coat on one nail, dip in color powder at 45 degrees, tap off. Repeat on all nails.
2. Second Base Coat and color powder.
3. Third Base Coat, dipped into the Clear Color Set Powder. Dust off.
4. Activator, one generous coat, capping the free edge. Wait until the powder hardens.
5. File with 180 grit, buff with 100 then 220 grit. Remove dust.
6. Second Activator coat over the whole nail. Wait a few minutes.
7. Top Coat, two to three quick strokes. Dry, then a second coat.

The base coat appears three times, the activator twice, the top coat twice. That ratio is the same idea in four-step systems, with the prep or bond step added once at the start.

Using the liquids with AIO powder

All-in-one (AIO) powders can be used as dip as well as acrylic. Kiara Sky says its All-in-One powders are designed to work with its dip essentials, which it lists as Dip Bond, Base, Seal Protect and Top Coat, and with its EMA monomer for acrylic. Its example dip sequence is: prep the nails, apply Bond, then Base, then the All-in-One Natural powder; two more coats of Base and the color powder; the first coat of Seal Protect and file; the second coat of Seal Protect, wipe the excess, and finish with the Top Coat.

The lesson is that an AIO powder does not skip the liquids. If you use it as dip you still need the base, the activator-type step and the top coat. See AIO powders explained for the full difference between using AIO as dip and as acrylic.

Safety notes for liquids

These liquids are strong adhesives and are meant for the nail, not the skin. OPI lists ethyl cyanoacrylate, polymethyl methacrylate and hydroquinone as ingredients in its Powder Perfection top coat, and labels the line professional only. The exam-prep guide notes that activators can produce vapors and sensitize skin, so ventilate and keep resin off living skin.

The AAD names the adhesives in dip as the main allergy culprit and recommends a one-nail test for a first dip manicure. Allergic reactions can start hours to days after the service. If you notice swelling, itching or bumps around the nail, remove the dip and see the guidance in the dip powder guide.

Keep bottles away from children, heat and open flames. Wipe up spills with a lint-free wipe and throw it away; do not leave wet product on a surface.
