What is a likely cause if a new acrylic coat separates into small beads?

Answer and explanation

Correct answer: The surface had grease or a water-repellent substance

The governing surface-preparation concept is adhesion and wetting. Acrylic paint must spread and bond to a clean, suitably receptive surface. Grease, wax or another water-repellent contaminant makes the surface resist the water-based coating, causing it to contract into small beads; therefore option B is correct. Paint darkness, brush cleanliness and background lightness do not normally produce this beading defect.
