Red Seal Concrete Finisher Practice Exam

What type of finish can be achieved by brooming the surface after the final set?

1. A smooth finish

2. A glossy finish

3. A textured finish

4. A polished finish

The correct answer is: A textured finish

Brooming the surface of concrete after the final set is a common technique used to create a textured finish. This process involves dragging a broom across the concrete surface, which creates small grooves or ridges. These grooves enhance the traction of the surface, making it safer, especially in wet conditions. Textured finishes are particularly useful in outdoor environments or areas prone to slipping, such as driveways, sidewalks, and patios. A smooth finish, in contrast, is typically achieved through methods like troweling or using a float, which do not involve the application of a broom. A glossy finish is usually the result of applying sealers or polish after the surface is completely cured, rather than through mechanical means like brooming. A polished finish takes this further, requiring specialized equipment and techniques beyond brooming. Therefore, the best representation of the finishing technique described is indeed a textured finish, resulting from the brooming process.
