If you love gel manicures, chances are you’ve come across Builder in a Bottle (BIAB) — a favorite for those seeking a natural, long-lasting finish without relying on acrylic or hard gel. But when it’s time to take them off, many wonder how to do it without damaging their natural nails.
How To Remove BIAB Nails: A Quick Guide is here to help, with easy steps used by nail techs that you can follow at home. Let’s get started!
Why Is BIAB So Hard To Remove?
BIAB can be tricky to remove as it's a tough, long-lasting gel that’s made to reinforce your nails. Unlike regular gel polish or shellac, it doesn’t come off easily with standard removers. To take biab nails off safely without harming your natural nails, you’ll need a bit of patience and the right tools.

Step-By-Step: How To Remove BIAB Nail
Essential Tools For BIAB Removal
Having the right tools ready makes removing BIAB much easier, and keeps your natural nails safe in the process.
Acetone
Aluminum foil
Cotton pads
Cuticle pusher
Nail file
Nail buffer
Cuticle oil
Hand cream
Here is a step-by-step guide on how to remove BIAB nails at home using safe and effective techniques.
Step 1: File The Top Layer
Start by gently filing the top layer of your BIAB nails with a nail file. The aim is to remove the glossy finish so the acetone can soak in and work its magic, no need to press too hard, just a light buff will do.
Step 2: Soak Cotton Pads In Acetone
Next, soak some cotton pads in pure acetone until they’re fully wet. You might be wondering if acetone removes BIAB. The answer is yes. Acetone helps break down the builder gel, making it soft and easier to take off without harming your natural nails.
Step 3: Apply Cotton Pads To Nails
Place the soaked cotton pads directly onto each nail. Make sure the gel surface is fully covered for effective soaking.
Step 4: Wrap Nails With Foil
After putting the acetone-soaked cotton pads on your nails, wrap each finger with foil. This keeps the pads in place and stops the acetone from drying out, so it works better to remove the gel.

Step 5: Wait 10-15 Minutes
Soak your nails for 10–15 minutes, depending on how thick the BIAB gel is. The acetone breaks down the gel’s polymer bonds, causing it to soften and lift. Once the gel starts to lift or bubble, it’s ready to be removed.
Step 6: Remove Foil And Cotton Pads
Carefully remove the foil and cotton pads. The BIAB gel should be soft, so take care not to be too rough.
Step 7: Gently Push Off Remaining BIAB
Gently push off the softened BIAB gel using a cuticle pusher or orange stick. Don’t scrape or force it, as this can harm your nails. If any gel is still stuck, rewrap your nails and soak for a bit longer.
Step 8: Buff Your Nails
Once all the gel is off, use a nail buffer to smooth the surface. It helps remove any leftover bits and gets your nails ready for polish or a break.
Step 9: Remove Any Leftover Residue
If a few gel spots remain, gently push or buff them away. Take your time as your nails should feel smooth and healthy, not scratched or worn down.
Step 10: Moisturise Your Nails And Cuticles
Finally, apply cuticle oil and hand cream to rehydrate your nails and skin. Acetone can be drying, so this step is important for gentle removal and nail health.
Fixing Common Problems When Removing BIAB Nails
If the gel isn’t coming off easily, soak your nails again for another 10–15 minutes.
If you’re scraping too hard, gently push the softened gel with a cuticle pusher to avoid damage.
If your skin or cuticles feel irritated, take a break and apply petroleum jelly or moisturiser.
If your nails feel scratched or thin, use a buffer lightly and avoid over-filing.
If you’re not confident doing it yourself, consider booking a professional for safe removal and reapplication.
