How to Use This Calculator

Enter Medium (0=Oil, 1=Acrylic, 2=Watercolor), Layer Thickness (1-5), and Room Temperature.
Set Relative Humidity and Additive (0=None, 1=Accelerant, 2=Retarder).
Review the Touch-Dry Time (hours) result.
Use Safe to Recoat (hours) and Full Cure Time (days) to inform your decision.

How the result changes with Room Temperature

Medium (0=Oil, 1=Acrylic, 2=Watercolor): Painting medium: 0 = oil, 1 = acrylic, 2 = watercolor.
Layer Thickness (1-5): 1 = thin glaze, 2 = normal, 3 = moderate impasto, 4 = heavy impasto, 5 = extreme impasto.
Room Temperature: Ambient temperature in Fahrenheit. Warmer = faster drying.
Relative Humidity: Relative humidity percentage. Lower = faster drying.
Additive (0=None, 1=Accelerant, 2=Retarder): 0 = none, 1 = drying accelerant (Liquin, flow aid), 2 = retarder (clove oil, slow-dry medium).

Touch-Dry Time: Estimated time until the paint surface is dry to light touch.
Safe to Recoat: Minimum time before adding another paint layer.
Full Cure Time: Time for the paint to fully cure and harden.
Ready to Varnish: Minimum days before applying varnish.
Thickness Factor: How much thickness affects drying time.
Temperature Factor: Temperature's effect on drying (< 1 = faster, > 1 = slower).
Humidity Factor: Humidity's effect on drying (< 1 = faster, > 1 = slower).

Identify Input Parameters
4 parameters
Medium (0=Oil, 1=Acrylic, 2=Watercolor) = 0, Layer Thickness (1-5) = 2, Room Temperature = 70, Relative Humidity = 50 = 5 input(s) provided
Calculate Touch-Dry Time
101.82 = 101.82
Calculate Safe to Recoat
Safe to Recoat = touchDryHrs * 0.6
61.09 = 61.09
Calculate Full Cure Time
509 = 509
