Lavis Builder Gel In The Jar Ver 2 Collection

LAVIS Builder Gel in the Jar, Version 2: the sculpting builder in 18 shades

Builder gel in the jar is the brush-worked builder for a strengthening overlay on the natural nail, an apex under gel color, or an extension on a dual form; it is picked up with a separate brush rather than the brush in a bottle cap, cures to a hard gel that does not chip, break, or peel easily, and stays flexible enough for long designs. LAVIS Version 2 is the 2025 jar line at ND Nails Supply, 21 listings at wholesale: 00 Clear plus eighteen named colors in 30 mL jars with the name printed on the jar, the Set of 18, and the Fiber builder in a 15 g jar. The gel is more fluid than a typical jar builder, so it spreads evenly, and like the rest of the LAVIS builder line it is HEMA-free and TPO-free and cures with little heat. LAVIS quotes four weeks or more of wear with proper application, a low odor, and a formula it describes as non-toxic and eco-friendly. The shade numbers match the LAVIS poly gel line, so a salon that already runs LAVIS extensions knows the palette.

How to apply LAVIS Builder Gel in the Jar

1. Prep. Push back the cuticle, buff, dust off, and apply Protein Bond and Primer without curing, then one thin coat of LAVIS Base cured 60 seconds.
2. Frame layer, not cured. A very thin layer of builder from the jar over the whole nail, so the bead has something to hold onto.
3. Build. Lift a bead with a two-ended poly and builder brush, set it at the apex in the middle of the nail, push it toward the cuticle without touching skin, and draw the gel to the free edge; use a liner brush to pull it along both side walls. The jar gel spreads evenly, so work it with the brush rather than waiting for it to level.
4. Cure. A 3 to 5 second flash cure per finger, then a full 60 to 90 seconds for the hand. For a form extension, press the dual form on with the bead inside, check the underside, cure, and remove the form.
5. Finish. Refile as little as possible, since filing thins the apex; then gel polish over the build, or wear the color bare, and LAVIS Top.

At the fill, remove the old color, keep the builder foundation, reshape, reapply Protein Bond, and continue from the base step; full removal is by filing, as with any hard gel.

Jar or bottle: which LAVIS builder?

The bottle version (Builder Gel in the Bottle, also in a Version 2) applies with its own brush and, in Version 2, is thick like a rubber base so it holds its apex without turning the hand, which makes it the faster overlay for a gel tech. The jar version is for the tech who prefers to work from a pot with a separate brush: the 30 mL jar holds more product per unit than a bottle, the gel is more fluid than a typical jar builder so it spreads evenly, and the shades are the 2025 named nudes rather than the B-numbered bottle colors. Both do overlays, short extensions on a dual form, and the base for nail art. The jar palette here mirrors the poly gel numbers, so a salon can move a client between jar builder and poly gel without changing the shade.

Which shade for which service

• Strengthening overlay under gel color: 00 Clear.
• Sculpted French and pink-and-white: 01 French White on the tip over 03 Baby Pink or 07 Princess Pink.
• Nude builder set worn bare: 12 Himalayan, 16 Toasted Marshmallow, 17 Ambrosia, or 18 Apricot with a top coat.
• Long extensions and repairs: the Fiber jar, or Fiber as the apex layer under a color build.
• Milky and glazed looks: 02 Milky White or 13 Pink Vanilla as the whole nail.

Stocking the jar line for a salon

Start with 00 Clear, 01 French White, one pink, and one nude; that covers overlays, French, and the bare builder set. Add the Fiber jar if the salon sculpts long, and the Set of 18 once builder is a named service and clients choose the shade from a swatch. A 30 mL jar goes a long way because a bead builds one nail, and the reorder is by number, the same number as the poly gel and the bottle builder. Keep jars capped and away from the lamp, and use a dedicated builder brush cleaned with cleanser rather than acetone.

Why a jar builder set lifts or cracks, and the fix

• Lifting at the cuticle: the bead touched the skin or the base was skipped. Leave a hairline margin, always cure a base first, and press the first thin layer into the nail before the build bead.
• Cracking at the stress point: the apex was too thin or too far forward. Build the apex over the stress area, about a third of the way from the cuticle, and cure a second time from underneath on a long extension.
• Heat under the lamp: LAVIS builder is formulated for low heat, but any gel cured in one thick layer warms. Flash-cure each finger for a few seconds before the full cure, and build in two beads on a thick sculpt.
• The brush drags the gel: the brush was dipped in acetone. Clean builder brushes with gel cleanser only, and wipe between beads.

The Fiber jar: when to reach for it

The 15 g Builder Gel Fiber jar is the fiber-reinforced version of the LAVIS jar builder. It is not a color; it is the jar to use where a plain builder cracks: a long dual-form extension on a client who types all day, a repair over a split that has been glued, or the apex layer under a colored build on a nail biter. Apply it exactly as the colored jars, thin frame layer first, then the bead at the apex, and finish it under a colored jar, a gel polish, or top coat. One Fiber jar per station is enough; it is used a bead at a time on the nails that need it rather than on every finger.

Who buys the jar rather than the bottle

• The tech trained on acrylic or hard gel who is used to lifting a bead from a pot with a brush and placing it, and finds the brush in a bottle cap too small for the way she works.
• The salon that builds in named nudes. The 18 jar shades are the 2025 nude and pink palette with the name printed on the jar, so a client picks Himalayan or Toasted Marshmallow from the swatch stick and the tech reaches for the jar by name.
• The high-volume builder station. A 30 mL jar carries roughly twice the gel of a 15 mL bottle, so the busy station reorders less often and pays less per service.
• The salon that already runs LAVIS poly gel. The jar numbers match the poly gel palette, so a client who moves from a poly extension to a builder overlay keeps the same shade name.

The bottle still wins for the gel tech who wants a fast clear overlay under polish and for the salon that sells the numbered B01 to B36 colors as the finished nail. Most salons that carry both keep the bottle at the gel stations and the jar at the extension station.

Prep and brushes that make the jar work

Because the jar has no brush of its own, the choice of brush decides how clean the build is. A two-ended poly and builder brush picks up the bead with the flat end and shapes the apex with the other, and a fine liner brush pulls the gel to the side walls and draws the cuticle line, which is the step that separates a salon build from a home one. Clean both brushes with gel cleanser between beads; acetone stiffens the bristles and drags the gel. On the nail itself, the fill that lasts starts with LAVIS Protein Bond and Primer on the bare plate and a thin cured LAVIS Base; skipping either is the most common reason a jar build lifts at the cuticle in the second week. Because the LAVIS builder line cures with little heat, the jar can be built in one fuller bead on a healthy nail without the flash of heat that makes clients pull their hand out of the lamp, though a thin sculpt on a thin or damaged nail is still built in two.
