What is a possible reason for a new acrylic layer failing to spread evenly over a dry surface?

Answer and explanation

Correct answer: Presence of oil or dust on the surface

A clean, suitably prepared surface supports adhesion and an even film. Oil, grease, or dust creates a contaminating barrier, causing the new acrylic layer to repel, skip, or spread unevenly; therefore option A is correct. A suitable primer normally improves the surface, a clean brush avoids transferred debris, and thorough mixing helps distribute pigment and binder. Those three practices are solutions or helpful conditions, not likely causes of the problem.
