Perfecting Your Prep: Manual vs E-File Nail Preparation
Prep, prep, prep. It’s something you hear time and time again as a nail technician, but there’s a good reason for it. Perfect prep is the foundation of every long-lasting, healthy, and flawless set.
In this guide, we’re breaking down why prep is so important, what it looks like in practice, and how to choose between manual or e-file methods depending on your training, tools, and client needs.
Why Nail Prep Matters
Nail prep isn’t just a step. It’s the foundation of every great set. Done right, it prevents lifting, boosts adhesion and keeps nails healthy.
-
Prevents infection: Proper cuticle work reduces the risk of bacterial and fungal issues. Push and lift gently, and avoid repeated passes with tools or bits to minimise trauma.
-
Creates a smooth surface: Removing non-living tissue and evening out the nail helps your product apply flawlessly and wear evenly.
-
Helps prevent lifting: We recommend using pure acetone instead of a nail dehydrator to fully remove oils, especially under the free edge. Think crisp grease. Get it all off before you start for the best results.
-
Improves retention: Great prep leads to long-lasting results. Use a 150 grit file with a light hand to remove shine. Once you see texture, move on and avoid overworking the area.
-
Protects the natural nail: HEMA-free systems rely on effective prep for proper adhesion. The nail needs enough texture to grip, Always replace tools regularly to keep them safe and effective.
-
Supports adhesion: Without HEMA, prep does more of the work. Clean nails, consistent texture and sharp, well-maintained tools all help your product bond properly and stay in place.
Why does it differ from brand to brand and for HEMA Free brands?
The key to long-lasting results is in skilful prep of the natural nail, this is especially true for HEMA-Free gel products. You might be wondering why. Let's break down the reasons. HEMA is the monomer that enhances the adhesion of a coating on the nail plate. Higher percentages of HEMA allow for maximum adhesion with minimal nail prep. When HEMA isn't present, prep becomes more important to ensure a safer long-lasting manicure.
Manual Nail Prep
What is it?
Manual prep involves using hand tools like nail files, cuticle pushers, nippers and buffers to prepare the nail plate and surrounding skin.
Why you might choose this method:
-
No machinery needed, making it ideal for mobile techs or those just starting out
-
Easier to control and refine your technique as you learn
-
Some clients find it more familiar and reassuring
-
Great for detailed, precision work on delicate skin types
Things to consider:
-
Takes more time to complete, especially for full sets
-
Can be more physically demanding on your hands and wrists over time
-
May be less effective on clients with thicker skin or stubborn cuticles
E-File Nail Prep - PROFILE
What is it?
E-file prep uses specialised drill bits to exfoliate the nail plate and surrounding skin quickly and efficiently.
Why you might choose this method:
-
Speeds up your prep process, especially for back-to-back appointments
-
Delivers consistent results when used correctly
-
Reduces physical strain on your hands and wrists
-
Offers a wider range of bit options for different nail and skin types
Things to consider:
-
Requires proper training and confidence to use safely
-
Can cause damage if incorrect speed, angle or pressure is applied
-
Some clients may be hesitant if they’ve had bad experiences in the past
How to Prep with an E-File
Using an e-file can completely transform your prep process making it less physically demanding. But as with any professional tool, proper technique and training are key.
At HONA, we always recommend completing accredited training before using an e-file on clients. The tips below are based on our experience with hypoallergenic systems and are here to guide you through safe, effective prep techniques once you’ve been properly trained.
Our Top Tips
-
Keep your bits sharp and clean: Replace them regularly and clean thoroughly to maintain performance and safety.
-
Master your angles and speeds: A light touch is everything. Heavy pressure or incorrect positioning can lead to damage.
-
Maintain your machine: A clogged or poorly serviced e-file can affect results and client comfort.
Recommended Bits for Beginners
If you’re just getting started, here are the essential bits we recommend:
-
Flame Bit: Ideal for lifting the proximal fold and accessing side walls gently and precisely.
-
Barrel Bit: Great for exfoliating dry skin without applying excess pressure.
-
Sanding Bands: Use only on very low speed (around 2,000 RPM) for a brief, controlled pass to etch the nail. Always change your sanding band between hands to maintain grit and hygiene.
Basic Step-by-Step
-
Gently lift the proximal fold using a flame bit. This creates space for safe and thorough cuticle work.
-
Exfoliate the cuticle area and side walls with your flame or barrel bit, depending on skin type.
-
Etch the nail plate using a sanding band or a hand file, ensuring light pressure and consistent motion.
-
Clean away dust and move on to your chosen product application.
