Protective Coatings Application: Dehumidification

Objective: To recognize how dehumidification is used as a method of controlling environmental conditions during surface preparation and coating activities.

  • Relative humidity is expressed as the amount of moisture in the air compared to the maximum amount possible.
  • Relative humidity has a major bearing on surface preparation and coating application.
  • Low relative humidity means very little corrosion.
  • Relative humidity is expressed as % up to 100%.
