What is the typical effect of finishing in only one direction compared to two directions?

• A. Reduces time to finish
• B. Creates waves that grow larger with repeated passes
• C. Improves Uniformity
• D. Increases surface strength

Answer: (B)

Finishing in a single direction mostly affects the surface texture and how evenly it lays down. When you drag the trowel or float in the same orientation for every pass, the pressure and paste movement align in that one direction. Each additional pass reinforces those same marks, so the ridges build up and the surface can develop wave-like undulations. That’s why the typical result is waves that grow larger with repeated passes. Finishing in two directions helps break up and fill those ridges, giving a flatter, more uniform surface. The other options don’t match what usually happens with one-direction finishing.
