Gel Curing Calculator
Calculate gel nail curing times based on lamp type, wattage, gel type, and coat thickness.
About this calculator
This calculator estimates lamp-on seconds for curing gel layers across a full nail set, from per-coat timing through batch curing and electricity use. Lamp type selects a base cure time and reference wattage — UV at 120 seconds and 36 watts, LED at 30 seconds and 48 watts, hybrid at 45 seconds and 36 watts (lines 28-40). Wattage then scales time inversely via reference wattage divided by your lamp wattage, floored at 0.4 so very high-wattage lamps cannot shrink cure time below forty percent of the base (line 43). Gel type applies a fixed multiplier — builder gel longest at 1.5, color at 1.0, base at 0.8, top coat shortest at 0.7 (lines 46-47) — and coat thickness adds 0.7 plus the thickness step times 0.3 (line 50). Per-coat seconds round the product of base time, wattage factor, gel factor, and thickness factor (line 53).
Per-nail time multiplies per-coat seconds by coats per nail (line 56). Total service seconds assume five-finger batches: ceiling of nail count divided by five batches, each batch cured once per coat rather than curing each nail individually (lines 59-61). Total cure minutes convert those seconds with one decimal place (line 64). Energy per service multiplies lamp wattage by lamp hours derived from total seconds (line 67). Flash cure uses a separate base — 30 seconds for UV, 10 for LED and hybrid — scaled by the same wattage multiplier for quick surface setting (line 73).

How to Use This Calculator
- Select your lamp type from the dropdown: UV lamp, LED lamp, or UV/LED hybrid.
- Enter the lamp wattage (W) — common values are 36W UV or 48W LED.
- Choose the gel type (base coat, color gel, builder gel, or top coat) and coat thickness.
- Enter number of coats per nail and total nails to cure (10 for a full set).
- Read the recommended cure time per coat (sec) and total cure time (min) for the full service.
- Use the energy per service (Wh) and cost per cure cycle to estimate monthly lamp operating costs.

Frequently Asked Questions
Why does higher lamp wattage shorten cure time per coat?
Wattage enters through an inverse multiplier: reference wattage for your lamp type divided by the wattage you enter, with a floor of 0.4 (line 43). That multiplier multiplies the base cure seconds along with gel type and thickness factors before rounding to per-coat seconds (line 53). A more powerful lamp therefore reduces seconds per coat, but never below forty percent of the type's base time.
How does nail count change total cure time without changing per-coat seconds?
Per-coat seconds depend on lamp, gel, and thickness inputs only (lines 28-53). Nail count instead drives how many five-finger batches are needed via ceiling of nail count divided by five (lines 59-60). Total cure time multiplies per-coat seconds by coats per nail and by batch count (line 61), so more nails extend service time through extra batches rather than longer individual coats.
Why does builder gel take longer to cure than top coat at the same settings?
Gel type applies a lookup multiplier before per-coat time is rounded (lines 46-47, 53). Builder gel uses 1.5 while top coat uses 0.7, so the same lamp wattage and coat thickness produce more than twice the per-coat seconds for builder gel compared with top coat. Color gel at 1.0 sits between those extremes as the neutral reference.
What is flash cure time and how does it differ from full cure per coat?
Flash cure is a separate quick surface-set estimate, not a fraction of full cure time. UV lamps use a 30-second base while LED and hybrid use 10 seconds, each scaled by the same wattage multiplier used for full coats (line 73). Full per-coat seconds still come from the base time, wattage, gel type, and thickness product (lines 28-53).
