Acrylic (Liquid and Powder) Nail Enhancements
What the exam tests
Acrylic questions test monomer and polymer chemistry, bead ratio, product control, and safe application. You must understand that curing is polymerization, not evaporation, and that the liquid-to-powder ratio controls strength, shrinkage, and lifting risk.
Core concepts
- Use ethyl methacrylate monomer and polymer powder; never use methyl methacrylate, which is not approved for cosmetic nail use.
- A proper bead is workable, not runny; too wet causes shrinkage and lifting, too dry causes brittle, flaky product.
- Apply in thin, controlled layers, keep product off skin, and build the apex at the stress zone.
- Polymerization begins when liquid and powder meet; set time is affected by ratio, temperature, and humidity.
- File cured product with controlled strokes; overfiling thins the enhancement and damages the natural plate.
Worked example
A bead is so wet that it runs toward the cuticle. You do not chase it with more powder after it has begun to set. You remove it, adjust to a firmer bead, and reapply with a margin at the cuticle. The reasoning: a wet bead shrinks as monomer is used up, creating stress and lifting at the edges.
Traps
Adding monomer to already set product. Using too much primer. Touching skin with uncured acrylic. Overfiling the natural nail. Judging set time only by the clock.
