Humidification for spray painting - Surface treatment
The correct relative humidity (RH) is essential for optimal spraying results. With the correct RH during the spraying process, the open time of the paint is extended, which gives the paint time to settle better, so that a smoother and tighter result will be achieved.
In addition, the risk of static electricity is considerably reduced and the dust formation in your rooms will decrease.
If water-based paint is sprayed on a hygroscopic surface, it may be beneficial to create a so-called Flash-off zone immediately after spraying. in a flash-off zone the RH is kept artificially high so that the paint has time to dry from the inside out. Immediately after spraying, the product is placed in this artificially damp room(flash-off zone) for a short period of 5 to 15 minutes. The result produces a quicker paint transfer speed, a more even finish which makes the overall appearance more appealing.
