What is a possible result of dust remaining beneath an acrylic paint layer?

Answer and explanation

Correct answer: Adhesion may weaken and the surface may become uneven

The governing concept is surface preparation and adhesion. Paint bonds best when it contacts a clean, suitably prepared ground. Dust acts as a loose intermediate layer, preventing direct contact between acrylic and the surface; it can cause weak adhesion, small bumps, pinholes, or an uneven finish. Option D is correct. Dust does not increase transparency or painting size, and it cannot restore or renew a brush.
