Red Seal Painter and Decorator Practice Exam

What can adding a sealant help improve on a painted surface?

1. Color intensity

2. Scratch resistance

3. Drying time

4. Color mixing

The correct answer is: Scratch resistance

Adding a sealant to a painted surface primarily enhances scratch resistance. Sealants create a protective barrier over the paint, which helps to guard against physical damage, including scratches and scuffs. This is especially important in high-traffic areas or surfaces that may be subject to wear and tear, as it extends the life of the paint job and maintains the surface's aesthetic appeal. While sealants can sometimes influence the overall look of a painted surface, such as providing a glossy or matte finish, their primary function is to add durability and protection. For example, in a kitchen or bathroom, where surfaces are frequently cleaned or exposed to moisture, sealants help maintain the integrity of the paint underneath. This protective measure is crucial in ensuring that the painted surface remains visually appealing and functional for a longer period. The other options do not accurately reflect the main benefits of sealants on painted surfaces.
