Orange Peel

(Poor Flow, Texture)

Paint film having an uneven texture, much like the skin of an orange.

Common Cause

The paint is under reduction. The viscosity is too high for spray conditions.
Thinner/reducer evaporates too fast for spray conditions.
Extreme shop temperature. When ambient temperature is too high, droplets lose more solvent and dry out before they can flow and level properly.
Improper gun adjustment and techniques.
① Excessively thick or thin film, spray gun too far from surface.
②Incorrect compressed air pressure and nozzle adjustment.
Improper flash-off or recoat time between coats.

Reduce to proper viscosity in recommended ratio.
Select recommended thinner/reducer based on temperature, humidity, air movement, and size of repair.
Use proper gun adjustments, techniques, and air pressure.
Ensure sufficient flash-off and drying time.
Prepare and sand substrate correctly.
Avoid temperature and humidity extremes. The temperature of the substrate shall be less than o 50 C. Recommended air temperature is around o 20 C.

(1) Compound or polish to reduce surface texture.

(2) Or, sand smooth with very fine grit sandpaper, compound and polish to restore gloss.

(3) Or, sand down to smooth surface and refinish.
