Overspray Cratering

Appearance

Small particles of coating that reach the surface not intentionally sprayed (such as overspray from an interior nonstick reaching the exterior of a pan).

Probable Causes

Too much overspray in application process.

Suggested Solutions

  1. Move the spray gun closer to the surface; reduce the velocity of the spray; increase the ratio of coating to the air in the spray.
  2. Mask part to avoid overspray reaching other surfaces.
  3. Increase air exhaust around parts to remove overspray.
