Which practice helps ensure uniform plaster thickness?

• A. Varying trowel angle
• B. Maintaining consistent trowel angle and pressure
• C. Using a different trowel for each section
• D. Skipping cure time

Answer: (B)

Uniform plaster thickness comes from controlling how much material you put on the surface with each pass. Keeping the trowel at a steady angle and applying the same amount of pressure throughout the job ensures the plaster is spread evenly, so the layer remains uniform across the wall. If you vary the angle, you change how much plaster the blade lays down and how it compresses, which creates thicker spots and thinner spots. Using a different trowel for each section can introduce slight differences in blade shape and edge feel, causing inconsistent deposits and thickness. Skipping cure time doesn’t affect thickness itself—it affects drying, strength, and cracking risk. In short, a steady angle and constant pressure are the best way to achieve uniform thickness.
