What is the main function of an isolation coat in an acrylic painting?

Answer and explanation

Correct answer: To form a protective barrier between the paint layer and final varnish

The governing conservation concept is separation of layers. An isolation coat forms a clear intermediate barrier over the cured acrylic paint, helping protect the paint film if a removable final varnish later needs cleaning or replacement. Option D is correct. It does not cut the canvas, instantly dry paint, or convert acrylic into oil colour; those functions are unrelated.
