common mistakes
Spraying too close
Make sure to spray at a distance of 15cm
Painting in humidity
Humidity will affect the drying time and how the paint dries, sticks, and looks on a surface.
High humidity slows drying, causes blushing and hazing, and results in poor adhesion
Wrong waiting time between layers
Waiting too long between layers will cause low adhesion. Not waiting enough time will also cause low adhesion but to the previous surface.
Touching before curing
This wil leave permanent marks on the paint which you will need to redo the job to get rid of it
