Frequently Asked Questions About BIABs

Do I need a base coat under the charcoal black BIAB™?

No! The off-black BIAB is a buildable gel that does not need a base coat polish before you apply the builder gel. Using a base coat or primer can help create a long-lasting finish but is not needed for this red builder gel.

How do I apply the charcoal black BIAB?

Applying the off-black BIAB gel is a five-step process:

Prep the nails by cleaning, pushing back cuticles, filing, gently buffing, and dehydrating the nail plate.
Apply the first layer of the off-black BIAB, and cure with The GelBottle Inc Light the Way Nail Lamp.
Apply the second layer of BIAB, and cure with the Light the Way Nail Lamp.
Apply TGB Extreme Shine Top Coat, Glazed Top Coat, or Matte Top Coat, and cure with the Light the Way Nail Lamp.

Is the charcoal black BIAB gel cruelty free?

Yes! Our off-black BIAB is vegan and cruelty free. Our builder gels do not use animal byproducts or testing, and all our products are Leaping Bunny Certified. This is great to have in your salon or nail tech kit for clients who only use vegan gel polish.

How long does the off-black builder gel bottle last?

The charcoal black BIAB in the 20ml bottle can last for 25 to 65 sets, depending on the nail and extension length, and the 7ml bottle can last up to 40 sets.

Can I use the charcoal black BIAB on natural nails or tips?

Both! The off-black BIAB works beautifully on overlays, tips, and natural nails. It even strengthens and protects your nails by reinforcing them with hard, durable layers of gel.

What is the best season to wear the off-black builder gel?

This charcoal black BIAB is a classic for the fall and winter seasons. Help your clients elevate their cozy outfits with this splash of off-black. Read more about different gel polish colors for each season from our blog.

Does BIAB have HEMA?

Our NU All-in-One and Clear All-in-One BIAB contain 50% less HEMA, which means no heat spikes while maintaining the same self-leveling, super strong results as our original BIAB formula offers.

How do I remove navy blue builder gel polish?

Removing charcoal black gel polish is a five-step process:

Start by cleaning the nails thoroughly.
Use the 120/180 grit file to remove the top coat of gel until there is no more shine.
Soak TGB Lint-Free Wipes in 100% acetone, and wrap nails in foil or TGB nail clips for 10 to 15 minutes.
Remove the foil or nail clip from one nail at a time, and scrape off the gel before starting the next nail. Use a TGB Cuticle Pusher to remove the remaining gel.
Buff nails if there is any base coat left, then shape the natural nail.
