Why is it important to remove dust from a dry acrylic layer before applying new paint?

Answer and explanation

Correct answer: The new layer adheres better and the surface remains clean

The governing concept is surface preparation and adhesion between paint layers. Dust forms a loose barrier on a dry acrylic surface, so a new coat may stick unevenly, show unwanted specks, or lose a clean finish. Removing it makes the surface cleaner and supports more reliable adhesion, so option A is correct. Dust does not always darken colour, change brush size, or make paper wetter.
