Red Seal Drywall Finisher and Plasterer Practice Exam

What is the characteristic of a "knockdown" texture finish?

1. A smooth finish with no texture

2. A flat surface with random patterns

3. A textured finish achieved by flattening joint compound lightly after spraying

4. A finish made with a roller

The correct answer is: A textured finish achieved by flattening joint compound lightly after spraying

The characteristic of a "knockdown" texture finish is that it is achieved by initially applying a textured spray of joint compound and then lightly flattening it using a wide knife or trowel. This technique creates a unique appearance where the peaks of the texture are knocked down, resulting in a softer and more subdued texture compared to other finish types. This method combines the visual interest of texture with a degree of smoothness, making it a popular choice for ceilings and walls in residential and commercial spaces. The end result is a finish that provides depth and dimension while also allowing for easier cleaning and maintenance compared to rougher textures. By contrast, a smooth finish with no texture or a flat surface with random patterns lacks the dimensionality associated with knockdown finishes, and a roller finish generally creates a more uniform texture that does not involve the same flattening technique.
