Multiple Choice

Which paint finishing defect resembles the texture of an orange?

Orange peel is a texture issue where the painted surface has tiny bumps and valleys, giving it a citrus-skin look. This happens when the coating doesn’t flow out evenly during drying, leaving a rough, dimpled finish rather than a smooth one. The underlying idea is that the film isn’t leveling properly, often from too-thick paint or poor atomization. Common causes include high viscosity, using the wrong reducer, spray gun settings that don’t atomize well (like too large a nozzle, too high or too low air pressure), insufficient flash time, or environmental factors that hinder leveling. Fixes involve thinning the paint to the correct viscosity, adjusting spray gun parameters for finer atomization, maintaining proper distance and speed, and ensuring the surface is clean and properly prepped. Blistering would look like raised bubbles, fish eye as circular craters around contaminants, and runs as sagging drips—different textures or shapes that point to other problems.
