Drying times are generally related to air circulation, temperature, film thickness and number of coats, and will be
affected correspondingly. The figures given in the table are typical with:
* Good ventilation (Outdoor exposure or free circulation of air)
* Typical film thickness
* One coat on top of inert substrate
Substrate temperature 5°C 10°C 23°C 40°C

1. The surface should be dry and free from any contamination prior to application of the subsequent coat.
The given data must be considered as guidelines only. The actual drying time/times before recoating may be shorter or
longer, depending on film thickness, ventilation, humidity, underlying paint system, requirement for early handling and
mechanical strength etc. A complete system can be described on a system sheet, where all parameters and special
conditions could be included.
