Runs or orange peel are typically caused by incorrect spray technique; how should you address this?

• A. Adjust spray technique
• B. Change to a coarser grit
• C. Apply more coats with faster passes
• D. Increase temperature of environment

Answer: (A)

Runs and orange peel come from how the finish is being applied, not the material itself. The best fix is to adjust spray technique so the finish atomizes properly and lays down a smooth, even film. Focus on getting a consistent distance from the surface, moving with steady speed and uniform overlap, and controlling trigger timing so you don’t lay down too much material in one spot or drag the gun too slowly. Keep the spray gun perpendicular and maintain a steady pattern; if needed, fine-tune air pressure and fluid flow to match the coating and reducer so the spray comes out fine rather than heavy. When the technique is right, the film builds evenly and the texture becomes smooth without runs or orange peel.

Other options don’t address the actual spray behavior: changing grit affects sanding after the finish, not how it’s sprayed; applying more coats with faster passes risks more material buildup and worsens defects; increasing the room temperature changes drying and viscosity but doesn’t fix the spray pattern itself.
