What is a "screed board" used for in the concrete finishing process?

A "screed board" is primarily used as a straight edge in the concrete finishing process. Its main function is to level and smooth the surface of freshly poured concrete, ensuring that it is uniformly flat and has the desired finish. The screed board is typically guided along the edges of the frame that holds the freshly poured concrete, allowing the finisher to remove excess material and create a level surface.

Using a screed board is critical because it allows concrete finishers to achieve the correct thickness and texture, which are essential for the durability and aesthetics of the concrete slab. Without proper leveling, the surface can have imperfections that may lead to issues like water pooling or uneven wear over time. Overall, the screed board is a fundamental tool in the initial stages of concrete finishing, directly influencing the quality of the finished product.
