Orange Peel Effect

Definition:
Orange Peel is when the texture of a painted surface is rough and wavy, similar to the texture of an orange. This is caused by roughness in particles that were not well atomized and paint that haven’t dried evenly.

 

Causes:
• Thinner used dries too quickly.
• When applying with a spray gun, causes may include spraying too close to the intended surface or the spray gun was not correctly set up causing paint particles sprayed from spray gun to not atomize perfectly.
• The spray viscosity is too thick especially on paint applications using a paint roller.

 

Solutions:
• Sand the surface affected by the orange peel effect and clean any dust leftover from sanding.
• Reapply paint coating after sanding.
• Use a thinner appropriate for the temperature of the environment; spray from a distance of 15 – 20 cm from the surface; viscosity according to recommendation from manufacturer; and spray gun air pressure and set up as recommended by manufacturer.
