Conditions:

  • Temperature between 5°C and 40°C.
  • Relative humidity of less than 85%, preferably between 10:00 and 16:00.
  • Ideally, apply when the temperature of the substrate is at least 2ºC above dew point and if possible away from direct sunlight.

Drying time: 
Surface dry, 1 hours, Hard dry, 8 hours at 23ºC.

Recoating time: 
16 hours at 23 ºC 
Note: higher temperatures will accelerate the recoating times (approximately halved for every 10ºC increase), whilst lower temperatures and high humidity will retard the recoating times (approximately doubled for every 10ºC decrease).

Requirements:
 One coat
