What effect do steel trowels have on the finish of concrete?

Steel trowels are specifically designed to provide a very smooth and hard finish on concrete surfaces. When a concrete finisher uses a steel trowel, it works by compacting the surface layer of the concrete, which helps to eliminate any imperfections left by previous finishing tools, such as floats. The action of the steel trowel closes off the surface pores of the concrete and gives it a dense, refined texture. This is important in various applications, especially where aesthetics are a priority or where a durable surface is required, such as in industrial floors or polished concrete applications.

A smooth, hard surface also facilitates easier cleaning and maintenance over time. Consequently, the use of a steel trowel is crucial in achieving the desired finish on concrete projects where a high-quality result is necessary.
