To ensure the color of the paint is accurate
To avoid the paint from bubbling
To reduce the texture of the finish

The correct answer is: To allow for better adhesion of the paint

Ensuring that the joint compound is dry before painting is crucial for achieving better adhesion of the paint to the surface. When paint is applied to a wet or damp joint compound, the moisture content can interfere with the bonding process. This may lead to paint peeling or flaking over time, as the moisture from the compound can cause the paint to lift off the surface. Additionally, if the joint compound is not fully dry, it can lead to an uneven surface that may become visible once the paint is applied. Proper drying allows for a smooth, uniform surface, which is essential for a professional-looking finish. By allowing the compound to dry completely, you can ensure that the paint adheres effectively and maintains its integrity over time.
