When the coating lifts on one client, it happens. Let us go through the causes of lifting one by one, from the most common to the least obvious.
When it lifts on half of them, it isn’t the clients. It’s the system.
Over years of working and teaching I have narrowed this down to six causes. They cover almost every case nail techs bring me.
Causes of lifting: the six most common
Almost all causes of lifting come down to nail prep rather than to the product. Here are the six I see most often.
1. Incomplete preparation
The most common one. The plate isn’t evenly buffed; shiny patches remain along the side walls or in the cuticle zone — exactly where a buffer is hardest to reach and easiest to overlook.
The check is simple: look at the dry, degreased plate at an angle to the light. Shine shows up immediately.
2. Leftover pterygium
The thin film that grows from the cuticle onto the plate. It is transparent and almost invisible — but the base bonds to it, not to the nail.
Ten days later the film separates, taking the coating with it. And it looks exactly like “it lifted at the cuticle”.
3. Dust
You swept with a brush and it spread dust across the plate. You blew it off and some settled back. Dust under the base is the same interlayer as pterygium, only finer.
Which is why degreasing comes after dust removal, not before.
4. Too much cuticle remover
The product ran into the lateral sinuses, stayed there, and the water in it didn’t go anywhere. Base won’t hold on top of that.
Especially with alkaline products, and especially when working in a hurry with no time to rinse the zone properly.
5. Material flooding the side walls
The most typical mechanical error. A thick layer of base runs onto the skin, the skin moves, it pulls the coating with it — and separation starts right at the edge.
The 0.3–0.5 mm gap from the walls isn’t cosmetic. It’s structural.
6. The wrong apex
This one is architecture. If the highest point sits in the wrong place, the load during flexing goes into the bond line instead of the body of the coating. The plate flexes, the coating doesn’t, and adhesion gives way first.
A thin plate with an unlevelled base is the classic recipe for cracks through the middle.
How to find the cause instead of guessing
Look at where it started.
- At the cuticle — preparation, pterygium, dust.
- At the sides — flooded walls, remover residue, an under-buffed edge.
- At the free edge — the edge wasn’t capped, or the stress zone is too thin.
- Through the middle — architecture and apex.
That isn’t a diagnosis, it’s a direction. But it almost always narrows things to one or two causes.
And honestly, about “heavy hands”
There is no such thing as a heavy hand. There are clients with thin plates, clients who use their hands more than most, clients who bite their nails.
All of that is input data that determines the material and the thickness you choose. Not an excuse — a condition of the task. ✨
Which of the six comes up most often in your work? I’m curious, because every nail tech has a favourite among them.
