A technician mixes a nail enhancement using liquid monomer and powder polymer. What is the primary risk of using a mix ratio with too much monomer and too little polymer?
- AThe enhancement will develop a permanent yellow tint
- BThe enhancement will not adhere to the nail tip at all
- CThe enhancement will cure too quickly and become brittle
- DThe enhancement will be weak, lifted easily, and may cause skin irritation from excess uncured product
Show answer & explanationAnswer & explanation
Correct answer: D. The enhancement will be weak, lifted easily, and may cause skin irritation from excess uncured product
A monomer-rich (wet) mix ratio results in a weak, porous enhancement that lifts easily and takes longer to cure, increasing the risk of skin irritation and allergic reaction from excess uncured monomer contacting the skin.
Why the other options are wrong
- A. Yellowing is more associated with UV exposure or oil contamination, not monomer ratio alone.
- B. A wet mix will still adhere, just poorly and with lifting issues, not zero adhesion.
- C. Excess monomer actually slows curing and produces a soft, weak product, not a fast-curing brittle one.
Monomer/Polymer Mix Ratio
The proportion of liquid monomer to powder polymer used to form nail enhancements; correct ratio is critical for durability and safety.
- Too wet (excess monomer) = weak, irritating product
- Too dry (excess polymer) = brittle, poor adhesion, service breaks
- Proper ratio produces a smooth, workable bead
Memory trick: Too wet = weak and itchy; too dry = crumbly and cracky.
