Which tool is used after floating to achieve the final surface finish in hand finishing?

• A. Screed
• B. Steel Trowel
• C. Bull Float
• D. Edger

Answer: (B)

In hand finishing, the final surface finish is achieved with a steel trowel. After floating, the goal is to compact and smooth the top layer until it becomes dense and has a uniform, slick look. The steel trowel’s hard blade presses and fills surface micro-voids, pushing enough cement paste to the surface to seal it and create that refined finish. Timing is important: wait until the concrete has stiffened enough to hold a slight indentation but is still workable; moving too early can gouge the surface, while moving too late won’t produce the smoothness you want. Screed is used for leveling while pouring, not for finishing the surface. A bull float smooths and raises cream during early stages, and an edger shapes the edges near forms. So the tool that best delivers the final hand finish is the steel trowel.
