The can says "recoat in 4 hours." That's at 70°F / 50% RH. Your garage isn't. StainTime calculates your actual dry time from real weather.
Example Calculation
Timing estimates based on manufacturer TDS and ambient conditions.
Always test on scrap first. StainTime does not guarantee finish outcomes.
Features
Green = apply now. Yellow = workable with caution. Red = wait. Backed by Arrhenius temperature kinetics and solvent-specific humidity thresholds.
Heated indoor, unheated garage, outdoor carport — each has different ambient conditions. StainTime models the difference automatically from your local weather.
Plan your full project: stain Friday → poly Saturday → recoat Sunday → final cure by next weekend. See your best 72-hour apply window. (Pro)
"Your walnut table is ready to recoat." Push alert fires exactly when your recoat window opens — never miss it again. (Pro)
Pine + oil stain + dry air = splotchy risk. StainTime cross-checks your wood species, finish type, and RH to flag the combinations that cause real defects.
Track multiple concurrent projects — tabletop, cabinet doors, deck boards — each with its own finish, coat number, and timeline. (Pro)
