Why is humidity important for paint booth?

Proper adhesion of paint and finish to surfaces does require high humidity level, too fast drying of freshly applied paint might cause orange peel effect or wrinkling of the finish or other flaws that will increase rejection rate.

Recommended humidity level for your paint booth

The recommended humidity level for painting application is 50 to 80% RH.

(Reference: ASHRAE Handbooks)

Some specific and more stringent humidity level might be required by Industry standard or coating manufacturer.

How can you bring humidity to your artifact conservation room?

Most of the humidifier technologies can be applied to humidify Paint or finishing booth.

Selection of the proper humidification solution should be based on the following:

  • What is the required maximum humidification capacity (load) required?
  • What sources of energy are available on site?
    Most of the time paint booth are equipped with gas fired heaters.
  • How is the ventilation system installed and how is the air distributed?
  • Which humidification system will require the least amount of energy – calculated for the overall HVAC system?

It is common for this application to require no drop of humidity during production process.

AEM evaporative humidifier and cooler is an efficient and eco-friendly solution to get proper humidity level to your paint booth. the same equipment can be used in summer to cool down the air in the paint booth reducing your load on other cooling equipment and reducing your energy bills.

Gas fired humidifier or other technologies able to deliver large humidity capacity can be considered.

Atomizing directly into paint booth should be avoided as any water droplets not fully evaporated would cause a paint application defect the same way a lack of proper humidity level can cause.
