Application

Apply only on a dry and clean surface with a temperature above the dew point to avoid condensation. Minimum temperature for curing is: -10°C/14°F. At the freezing point and below be aware of the risk of ice on the surface, which will hinder adhesion. The film formation may be adversely affected by light rain, high humidity and/or condensation during application and the following interval after application: 10 hours , 20°C/68°F In confined spaces provide adequate ventilation during application and drying.

Airless spray: 5-10% thinning is recommended. Under extreme conditions up to more than 20% may be necessary to obtain satisfactory film formation. Electrostatic spray: 10% thinning is recommended. Contact HEMPEL for more information. May be specified in another film thickness than indicated depending on purpose and area of use. This will alter spreading rate and may influence drying time and overcoating interval. Normal range dry is: 40-75 micron/1.6-3 mils.

Recommended basecoats: Recommended systems are: Hempel Hempadur 45141, Hempel Hempadur 45143, Hempel Hempadur Mastic 45880, or Hempel Hempadur 45881.
