Frequently asked questions
What is the main difference between BIAB (Builder in a Bottle) and traditional builder gel in a jar?
BIAB (Builder in a Bottle) is packaged in a convenient bottle with a built-in brush, making it ideal for quick overlays, nail strengthening, and short extensions. Its consistency is slightly thinner and self-levels quickly. Traditional builder gel in a jar has a thicker viscosity, requires a separate brush, and is preferred for building long extensions, sculpting custom shapes, and creating pronounced arches or apexes. Both formulas provide high-strength nail protection.
How does the "Low Heat" formula in Lavis Builder Gel prevent burning under the lamp?
When builder gels cure under UV or LED lamps, they undergo a rapid chemical reaction (polymerization) that releases heat, which can cause a painful burning sensation on sensitive nail beds. Lavis Builder Gel is formulated with specialized low-heat photoinitiators that slow down the curing reaction slightly during the initial seconds. This controls the exothermic reaction and prevents the painful heat spike, providing a comfortable, sting-free curing process for clients.
What are the benefits of using a HEMA-free and TPO-free builder gel?
HEMA (hydroxyethyl methacrylate) and TPO (trimethylbenzoyl diphenylphosphine oxide) are common chemical monomers and photoinitiators that are known allergens in nail cosmetics. Repeated skin contact can trigger contact dermatitis and permanent product sensitivities. Using Lavis HEMA-free and TPO-free builder gel protects both nail technicians and clients from developing these severe allergic skin reactions, ensuring a much safer salon environment.
What is a "Soft Flex Gel Polymer" Dual Form, and how is it used?
Unlike stiff plastic tips, Lavis Dual Forms are manufactured using a specialized Soft Flex Gel Polymer. This material flexes to match the natural C-curve of the nail, preventing air bubbles and minimizing product overflow at the cuticle. After curing, the flexible form pops off cleanly without force or risk of cracking the cured gel. Simply fill the form with builder gel, press it onto the prepped nail, cure, and release the form.
Can I refill builder gel, and how often should a refill be done?
Yes, refilling is highly recommended and represents one of the most profitable services for a nail salon. Instead of soaking off the entire set, the technician files down the top color layer and the outgrown portion of the builder gel. After prepping the new growth area, new builder gel is applied to the base, rebalancing the apex. Refills should be done every 2 to 3 weeks to prevent lifting and protect nail health.
Professional Builder Gel: The Definitive Guide for Salon Owners & Nail Technicians
As client demand shifts toward healthier, lighter, and more durable nail enhancements, professional builder gel has emerged as a cornerstone service for modern nail salons. Offering the strength of traditional acrylics combined with the flexibility and high-gloss finish of gel systems, builder gel allows nail technicians to provide overlays, reinforce natural nails, build structural apexes, and sculpt short-to-medium extensions.
Unlike traditional products that release heavy chemical odors or cause uncomfortable heat spikes under the curing lamp, modern builder gel systems prioritize client comfort. By stocking advanced formulas that are both HEMA-free and TPO-free, salons can protect both their technicians and clients from developing chemical sensitivities while expanding their service menus with premium, high-margin treatments.
Why Professional Salons Stock Builder Gel
Adding builder gel to your service menu is one of the most effective strategies to increase salon revenue and improve client retention. Clients choose builder gel because it feels lightweight and natural, resembling their own nails while offering outstanding durability. It provides up to four weeks of wear without chipping or lifting, compared to just two weeks for standard gel polishes.
For salon owners, builder gel offers excellent business margins. A single bottle or jar can support 30 to 40 complete services. With average service charges ranging between $45 and $60, a salon can recover the cost of a new bottle from just one client, turning the remaining applications into direct profit. Additionally, builder gel services save time. The self-leveling properties of high-quality gels reduce filing and shaping time by up to 10 minutes per set, allowing technicians to accommodate more clients each day.

- BIAB (Builder in a Bottle) Ver 1: Featuring a classic, medium-viscosity formula with a built-in brush, Ver 1 is designed for practiced technicians who prefer control over building arches. It requires a quick hand-flip to center the apex before curing.
- BIAB (Builder in a Bottle) Ver 2: This thick-viscosity formula performs similarly to a rubber base. It does not run or flood cuticles, allowing technicians of all skill levels to build structure without needing to flip the hand.

| **Technician Level** | Intermediate to Advanced | Beginner to Professional |
| **Built-in Brush** | Yes | Yes |
Curing Guidelines & Curing Times
Proper curing is critical to ensure the durability of the builder gel and prevent lifting. Curing times vary based on the lamp type and the thickness of the gel layer:
- LLED Lamps (48W or higher): Cure each builder layer for 60 seconds. For thick overlays or sculpting layers, a 90-second cure is recommended.
- UV Lamps (36W): Cure each layer for 120 seconds to ensure the UV light penetrates to the base layer.
- Flash Curing (Mini LED Lamps): Use a mini hand-held lamp to cure individual nails for 5 to 10 seconds immediately after placement to keep the gel from moving before the full hand is cured.
Step-by-Step BIAB Application Workflow
Follow this professional application process to ensure maximum adhesion and a perfect nail structure:
- Prep the Nails: Perform a standard dry manicure. Push back the cuticles, remove non-living tissue, and buff the nail surface gently to remove the shine. Cleanse with isopropyl alcohol to remove dust and oil.
- Apply Dehydrator & Primer: Apply a coat of dehydrator followed by a protein bond primer to maximize adhesion. Allow it to air dry completely.
- Apply Base Gel: Brush a thin layer of base gel over the nail. Cure for 30 seconds in an LED lamp.
- Create the Slip Layer: Apply a thin layer of builder gel over the entire nail without curing. This wet layer acts as a guide, helping the subsequent gel droplet flow smoothly.
- Place the Builder Droplet: Place a larger droplet of builder gel near the apex (the center of the nail). Use a detail brush to guide the gel toward the cuticle and free edge, keeping the product thin at the margins.
- Shape & Level: Allow the gel to self-level. For BIAB Ver 1, turn the client's hand upside down for 5 seconds to help the apex center. For Ver 2, verify the smooth surface under the light reflection.
- Flash Cure: Use a mini LED lamp to cure the nail for 5 seconds to lock the shape in place.
- Full Cure: Cure the entire hand in a professional LED lamp for 60 to 90 seconds.
- Finish: Wipe away the sticky inhibition layer with alcohol, shape the free edge if necessary, and apply your top coat.
Safety & Chemistry: HEMA-Free & TPO-Free
HEMA and TPO are chemical compounds commonly used in nail products to aid curing and adhesion. However, repeated exposure to these compounds can lead to skin allergies and irritation. Lavis builder gels are formulated without HEMA or TPO, providing a safer option that reduces the risk of allergic contact dermatitis. This formula change ensures a healthier environment for technicians who handle gel products daily.
Care, Maintenance & Refill Guidelines
Builder gel nails are easy to maintain, making them a popular choice for regular salon clients. Instead of removing the product completely during every visit, technicians can perform a refill service:
- Refill Frequency: Schedule refills every 2 to 3 weeks to maintain structural balance as the nail grows.
- Refill Workflow: File away the top coat and color layers. Remove any lifted sections of gel, prep the new growth area, and apply new builder gel to the base of the nail.
- Nail Care Advice: Encourage clients to apply cuticle oil daily and wear gloves during household chores to keep the nails hydrated and prevent lifting.
