How long does it actually take to watch paint dry?
1-8 hours for touch-dry, 30 days for full cure
30 days, 0 hours
📐 The Calculation
Latex paint: touch-dry in 1-2 hours, recoat in 4 hours, full cure in 30 days. Oil-based paint: touch-dry in 6-8 hours, recoat in 24 hours, full cure in 30-60 days. The molecules continue cross-linking for weeks after it feels dry.
Assumptions:
- • Room temperature: 70°F (21°C)
- • Humidity: 50%
- • Proper ventilation
- • Single coat on drywall
🤯 For Perspective...
Full cure (30 days) is longer than the Apollo 11 mission
Touch-dry time is about the same as one episode of a TV show
A snail could travel 150 feet while waiting for oil paint to dry
