24 to 72 hours between coats of tung oil
Allow 24 to 72 hours between tung oil coats for proper drying and curing. The exact time depends on temperature, humidity, and ventilation. Each coat must be fully dry before applying the next to prevent tackiness and ensure a smooth finish. Light sanding between coats improves adhesion.
Factors affecting drying time
- Temperature: 70°F (21°C) or higher speeds drying
- Humidity: Lower humidity reduces drying time
- Ventilation: Good airflow helps evaporate solvents
- Coat thickness: Thinner coats dry faster
- Wood type: Porous woods absorb oil differently
Comparison of drying times by method
| Method | Coat 1 | Coat 2 | Coat 3 |
|---|---|---|---|
| Wiping | 24 hours | 24 hours | 24 hours |
| Brushing | 48 hours | 48 hours | 48 hours |
| Flooding | 72 hours | 72 hours | 72 hours |
