What may be the main technical reason if a second poster-colour layer begins to disturb the first dry layer?

Answer and explanation

Correct answer: Too much water and repeated brushing in the second layer

The governing concept is controlled layering in opaque poster colour. Although the lower layer is dry, excess water can soften or reactivate its binder, and repeated brushing adds friction that lifts the pigment. Therefore, option A is correct. The first layer being clean, the brush being small, or the paper being white does not normally disturb a properly dried layer. Use a moderately thick mix, wait for drying, and apply the next coat with few gentle strokes.
