Red Seal Painter and Decorator Practice Exam

What is a common reason for priming surfaces before applying paint?

1. To decrease application time

2. To improve the durability of the paint

3. To make the paint smell better

4. To change the color of the final coat

The correct answer is: To improve the durability of the paint

Priming surfaces before applying paint is essential for several reasons, with improving the durability of the paint being a primary factor. Primers are specifically formulated to enhance the bond between the surface and the paint. This strong adhesion helps prevent issues such as peeling and chipping, thereby extending the life of the paint job. Additionally, primers often have properties that allow them to seal porous surfaces, reducing the amount of paint absorbed and providing a more uniform finish. This sealing effect contributes to durability, as it helps in protecting the surface underneath from moisture and other damaging elements, which can lead to deterioration over time. Other options, while they may have some relevance in specific contexts, do not fundamentally address the enhanced durability that priming provides. Primers do not generally aim to decrease application time or alter the smell of the paint; their primary role is to create an optimal surface for the paint and enhance its performance. Changing the color of the final coat is also a secondary concern of primers and is not their main purpose. Thus, enhancing durability is the most accurate reason for the necessity of priming surfaces prior to painting.
