Final answer:
The correct answer is option 2) Base coat, which is the second layer in the HardTop Floor Coating System, providing thickness and key properties like color and texture to the coating.
Step-by-step explanation:
The HardTop Floor Coating System is designed to protect and enhance concrete floors. It includes several layers, each serving a unique function in the protection and aesthetics of the floor. The typical system starts with a Primer, which is the initial layer applied to the clean concrete surface to ensure good adhesion of the coating and to help seal the concrete.
Next is the Base coat, which is a durable layer that provides the bulk of the coating's thickness and properties like color and texture. Following the base coat, a Top coat may be applied; this layer is often clear and designed to provide additional protection against wear, chemicals, and UV light. Finally, some systems might include a Sealer, which is applied to protect the top coat, enhancing durability and making the surface easier to clean. Each layer must be properly applied and cured to ensure the best performance of the coating system.
