What is a possible cause of fine cracks forming in an acrylic paint layer?

Answer and explanation

Correct answer: Drying an excessively thick layer unevenly

The governing concept is differential drying and film stress. In an excessively thick acrylic layer, the surface can dry and contract while moisture remains deeper inside. Uneven contraction places stress on the film and may produce fine cracks. Option D is correct. Properly dried thin layers, a suitable flexible support, and an appropriate medium generally reduce this risk rather than cause it.
