Why must an acrylic painting be completely dry before varnishing?

Answer and explanation

Correct answer: To prevent trapped moisture and surface damage

The governing concept is compatibility between a dry paint layer and a protective finish. If varnish is applied while acrylic is still wet or damp, moisture and soft paint may become trapped, causing cloudiness, unevenness, smearing, or poor adhesion. Waiting until the surface is completely dry allows the varnish to form a stable layer. It does not thin paint, renew a brush, or enlarge the canvas.
