Lifting
Lifting — product separating from the natural nail — is the most common acrylic complaint. The location of lifting is diagnostic:
| Where it lifts | Likely cause |
|---|---|
| Cuticle edge (proximal) | Product too close to cuticle; primer not reaching that area; prep missed the cuticle zone |
| Sidewalls | Product extending onto the lateral skin; insufficient prep at the sidewalls |
| Tip / free edge | Free edge not sealed; tip bond failure; tip not properly blended |
| Whole nail lifting off | Dehydrator or primer skipped; incompatible product; completely smooth nail plate (prep failure) |
Bubbles in the product
| Cause | Fix |
|---|---|
| Air trapped during bead placement | Place beads firmly without trapping air between bead and nail surface. Don't drag. |
| Working time exceeded before placement | Work faster with each bead once picked up; place and don't overwork |
| Over-working the bead | Place and smooth with minimum strokes; over-working introduces air |
| Too-dry bead | Porous consistency creates internal air pockets; use a medium-wet bead |
| Contamination in monomer | Replace monomer if consistently getting bubbles — contaminated monomer can cause issues |
Cloudy or discoloured product
| Cause | Fix |
|---|---|
| Moisture contamination during application | Work in a dry environment; don't blow on nails; keep monomer covered between beads |
| Over-wet bead | Excess monomer that doesn't fully react can create cloudiness; use correct ratio |
| Product contamination | Replace monomer if it has become contaminated (e.g. water, oil, colour pigment) |
| Wrong product pairing | Some monomer/powder combinations from different brands don't produce clear results; stay within a brand system |
| Age/degradation | Expired or improperly stored product degrades — replace aged stock |
Cracking and breaking
| Type of crack | Cause | Fix |
|---|---|---|
| Stress crack at mid-nail | No apex or misplaced apex; product too thin in the stress zone | Build a structural apex; see apex guide |
| Crack at free edge | Free edge product too thin; tip bond failure | Build more product at the smile line; ensure tip is properly bonded |
| Horizontal crack near cuticle | Product too thin at base; or lifting creating a stress point | Build more product near the base; address any lifting before it progresses |
| Surface micro-cracking | Product over-filed; too-thin application layer; product degradation | Don't over-file; maintain adequate product thickness; check product age |
Rough or grainy surface
A rough or grainy cured surface is almost always a too-dry bead problem:
- Too-dry bead: the powder doesn't fully bind; creates a porous, grainy texture
- Over-worked bead: working the bead too much as it begins to set pulls the surface
- Filing too early: filing before full cure tears the product
A rough surface can be addressed with filing and buffing once fully cured, but the underlying issue (bead ratio or filing timing) needs to be corrected at the process level.
Flooding the cuticle
Product that touches or overlaps the cuticle skin almost always lifts — the product bonds to the skin and lifts when the skin moves. Causes:
- Too-wet bead that runs before setting
- Placing the cuticle bead too far back (too close to the cuticle)
- Not checking the cuticle gap before curing
Uneven or missing apex
A flat nail (no apex) breaks easily; an apex in the wrong position creates nails that look unfinished or are still structurally compromised:
- Missing apex: product distributed evenly rather than built in the mid-nail zone
- Apex too far back: creates a thick nail near the cuticle, thin in the stress zone
- Uneven apex: different height on each nail, creating inconsistent side profiles
The solution is consistent lateral profile assessment during application. See: how to build a nail apex correctly.

Why do my acrylic nails keep breaking at the same spot?
Consistent breakage in the same location points to a structural issue. Breaking at the stress zone (mid-nail) usually indicates an absent or misplaced apex. Breaking at the free edge suggests the tip product is too thin. Breaking near the cuticle often points to lifting that's been ongoing — the product has separated from the nail and the remaining bond is under disproportionate stress.
Why does my acrylic look yellow after a few weeks?
Yellowing in cured acrylic is usually caused by: UV exposure (sunlight degrades some acrylic pigments), product contamination (certain pigmented gel polishes can migrate into acrylic), or the product itself if it's a lower-grade formulation. Use a UV-inhibiting top coat, and test your top coat product with your acrylic for compatibility to prevent pigment migration.
Can I fix lifting at home between appointments?
Advise clients not to — any gap between the product and the natural nail is a potential entry point for moisture and bacteria. Self-fixing with a home nail glue creates an additional layer over the problem rather than addressing it. The correct approach is to come in for a repair appointment.
