What is a likely cause if an opaque colour layer becomes powdery and flakes after drying?

Answer and explanation

Correct answer: Insufficient binding medium (binder) in the paint

The governing concept is adhesion within a paint film. Binder holds pigment particles together and helps the layer attach to the surface. If binder is insufficient, excess loose pigment remains on top; after drying, the coating may become powdery and flake. Thus option A is correct. A balanced mixture, thin controlled application, and a clean suitable surface generally improve stability rather than cause failure.
