Concrete finisher
From Wikipedia, the free encyclopedia
A concrete finisher, also known as a cement mason is a tradesman who works with concrete, which includes placing, finishing, protecting and repairing concrete in engineering and construction projects. Concrete finishers are often responsible for setting the concrete forms, ensuring they have the correct depth and pitch. Concrete finishers place the concrete either directly from the concrete wagon chute, concete pump, concrete skip or wheelbarrow. They spread the concrete using shovels and rakes, sometimes using a straightedge back and forth across the top of the forms to “screed,” or level, the freshly placed concrete. After levelling the concrete, they smooth the surface using either a hand trowel, a long handed “bull float” or powered floats. After the concrete has been leveled and floated, concrete finishers press an edger between the forms and the concrete to give a chamfered edges that is less likely to chip.[1][2] [3] [4]
